Knowledge graphs and machine learning integrate by using the graph's structured data to enhance AI algorithms. Machine learning models analyze the connections in the graph to make predictions, recommendations, or classifications, while the graph's structure helps improve the model's understanding of relationships, context, and underlying concepts. User please explain by excel table ChatGPT
In an Excel table, you can represent a simple knowledge graph and machine learning model. For example, imagine a small graph for movie recommendations: Entity ID Entity Type Entity Name Relationship Related Entity ID 1 Movie Movie A Director 5 2 Movie Movie B Director 5 3 Movie Movie C Director 6 4 Movie Movie D Director 6 5 Person Director 1 Directs 1,2 6 Person Director 2 Directs 3,4 User ID Liked Movie ID Disliked Movie ID 1 1, 2 3, 4 2 2, 3 1, 4
This table represents a small knowledge graph with movies, directors, and users. Machine learning models can analyze these relationships to make personalized movie recommendations based on user preferences and the graph structure. User please use "Markdown" code to explain this ChatGPT
Here's the same example using Markdown tables to represent a simple knowledge graph and machine learning model for movie recommendations:
Entities and Relationships: Entity ID Entity Type Entity Name Relationship Related Entity ID 1 Movie Movie A Director 5 2 Movie Movie B Director 5 3 Movie Movie C Director 6 4 Movie Movie D Director 6 5 Person Director 1 Directs 1,2 6 Person Director 2 Directs 3,4
User Preferences: User ID Liked Movie ID Disliked Movie ID 1 1, 2 3, 4 2 2, 3 1, 4
The first table represents the knowledge graph with movies, directors, and their relationships. The second table shows user preferences for movies. Machine learning models can analyze these relationships and preferences to make personalized movie recommendations based on the graph structure and user data. User I still don't see the combined of knowledge graph and machine learning ChatGPT
Apologies for the confusion. Here's a clearer example using Markdown tables to represent the combination of a simple knowledge graph and a machine learning model for movie recommendations:
Entities and Relationships: Entity ID Entity Type Entity Name Relationship Related Entity ID 1 Movie Movie A Director 5 2 Movie Movie B Director 5 3 Movie Movie C Director 6 4 Movie Movie D Director 6 5 Person Director 1 Directs 1,2 6 Person Director 2 Directs 3,4
User Preferences: User ID Liked Movie ID Disliked Movie ID 1 1, 2 3, 4 2 2, 3 1, 4
Machine Learning Model for Recommendations:
The machine learning model analyzes the relationships in the knowledge graph and user preferences to predict which movies a user might like. For example, a collaborative filtering model can be used for this purpose. User ID Recommended Movie ID Recommendation Confidence 1 2 0.8 1 1 0.7 2 3 0.85 2 2 0.75
The third table shows the output of the machine learning model, which uses the knowledge graph and user preferences to make movie recommendations. The model calculates recommendation confidence scores for each user, indicating how likely they are to enjoy a particular movie.
In this example, the knowledge graph provides structured data that the machine learning model can use to understand relationships between movies and directors, while user preferences help the model personalize its recommendations based on users' past likes and dislikes. User please show the input data for knowledge graph ChatGPT
The input data for a knowledge graph can come from various sources, such as databases, text, or APIs. To build a knowledge graph, you'll need to gather and structure this data as entities (nodes) and relationships (edges). In our movie recommendation example, the input data can be represented as follows:
Movies: Movie ID Movie Title 1 Movie A 2 Movie B 3 Movie C 4 Movie D
Directors: Director ID Director Name 5 Director 1 6 Director 2
Director-Movie Relationships: Relationship ID Movie ID Director ID 1 1 5 2 2 5 3 3 6 4 4 6
Here, we have three separate tables representing the input data for the knowledge graph. The first table lists the movies, the second table lists the directors, and the third table establishes the relationships between movies and directors.
To create the knowledge graph, you would combine this data, connecting movie nodes to director nodes based on their relationships, as shown in the "Entities and Relationships" table in the previous example. User how to get input data from knowledge graph ChatGPT
To extract input data from a knowledge graph, you'll need to traverse the graph and collect the nodes (entities) and edges (relationships) that you're interested in. There are several ways to do this, such as using graph query languages, APIs, or specialized tools. Here's a step-by-step process to obtain input data from a knowledge graph:
Identify the entities and relationships of interest: Determine which entities (e.g., movies, directors) and relationships (e.g., directed by) you want to extract from the knowledge graph.
Use a graph query language: Graph databases, such as Neo4j, use query languages like Cypher to query and manipulate the graph data. For instance, to obtain movies and their directors from a Neo4j database, you can use the following Cypher query:
less
MATCH (m:Movie)-[:DIRECTED_BY]->(d:Director)
RETURN m, d
APIs or graph libraries: If the knowledge graph is available through an API or accessible using graph libraries like NetworkX (Python) or JGrapht (Java), you can use them to programmatically extract the entities and relationships you're interested in.
Export data to a suitable format: Once you've collected the desired data, export it to a format that's easy to work with, such as a CSV, JSON, or a DataFrame. This way, you can analyze the data further or use it as input for other applications.
Preprocess the data: Depending on your use case, you might need to preprocess the extracted data. This could involve cleaning the data, handling missing values, or transforming it into a suitable format for your application.
In summary, you'll need to identify the relevant entities and relationships in the knowledge graph, use an appropriate method (e.g., graph query language or APIs) to extract the data, and preprocess the data as needed for your specific use case.

User please show the detail data from Extract relevant data from the knowledge graph by excel teble ChatGPT
I'll provide an example using the movie recommendation scenario. In this case, let's assume the knowledge graph contains information about movies, directors, actors, and genres. We'll extract relevant data from the knowledge graph to be used as input for a machine learning model.
The extracted data can be represented in the form of Excel tables:
Movies: Movie ID Movie Title 1 Movie A 2 Movie B 3 Movie C 4 Movie D
Directors: Director ID Director Name 5 Director 1 6 Director 2
Actors: Actor ID Actor Name 7 Actor 1 8 Actor 2
Genres: Genre ID Genre Name 9 Genre 1 10 Genre 2
Director-Movie Relationships: Relationship ID Movie ID Director ID 1 1 5 2 2 5 3 3 6 4 4 6
Actor-Movie Relationships: Relationship ID Movie ID Actor ID 5 1 7 6 2 7 7 3 8 8 4 8
Genre-Movie Relationships: Relationship ID Movie ID Genre ID 9 1 9 10 2 9 11 3 10 12 4 10
These tables represent the extracted data from the knowledge graph, including information about movies, directors, actors, genres, and their relationships. This data can be used as input for a machine learning model, such as a recommendation system, by converting it into feature vectors and following the subsequent steps outlined in the previous answer. User please put all data together become a excel table ChatGPT
Combining all the data into a single Excel table requires joining the tables based on their relationships. Here's a combined table that represents the movie data, including directors, actors, and genres: Movie ID Movie Title Director ID Director Name Actor ID Actor Name Genre ID Genre Name 1 Movie A 5 Director 1 7 Actor 1 9 Genre 1 2 Movie B 5 Director 1 7 Actor 1 9 Genre 1 3 Movie C 6 Director 2 8 Actor 2 10 Genre 2 4 Movie D 6 Director 2 8 Actor 2 10 Genre 2
Please note that this table assumes each movie has only one director, one actor, and one genre. In reality, movies typically have multiple actors and genres, and the table would need to be adjusted accordingly. Depending on the machine learning model, you might need to represent this data differently or use additional features to capture the relationships between entities. User Can you explain what's "Map model output to entities and relationships: Identify how the machine learning output data maps to entities and relationships in the knowledge graph." and give me a example by excel table ChatGPT
"Map model output to entities and relationships" means interpreting the output data from a machine learning model and connecting it to the relevant entities and relationships within the knowledge graph. It involves determining how the predicted or recommended data can be integrated into the graph structure.
Let's consider a movie recommendation system as an example. Suppose we have a machine learning model that predicts movie genres for a set of new movies. The output data from the model might look like this:
Machine Learning Model Output: Movie ID Movie Title Predicted Genre 5 Movie E Genre 1 6 Movie F Genre 2 7 Movie G Genre 1 8 Movie H Genre 2
To map this output data to entities and relationships in the knowledge graph, we need to identify how the predictions (genres) are connected to the existing entities (movies).
In this case, we'll create new relationships between the movies and their predicted genres. We can represent the updated knowledge graph as a table with additional rows for the new relationships:
Genre-Movie Relationships (Updated): Relationship ID Movie ID Genre ID Relationship Type 9 1 9 Actual Genre 10 2 9 Actual Genre 11 3 10 Actual Genre 12 4 10 Actual Genre 13 5 9 Predicted Genre 14 6 10 Predicted Genre 15 7 9 Predicted Genre 16 8 10 Predicted Genre
In this updated table, we've added new rows for the machine learning model's predictions, connecting the new movies (Movie E, F, G, H) to their predicted genres (Genre 1, Genre 2) with a "Predicted Genre" relationship type.
By mapping the machine learning output data to entities and relationships in the knowledge graph, you can integrate the model's predictions or recommendations into the graph structure, enriching the graph with new information or insights. User what's the "Update the knowledge graph with the model output data: Use an appropriate method like a graph query language or API to update the knowledge graph with new entities, relationships, or attributes based on the machine learning output data." please give a example by a excel table. ChatGPT
Updating the knowledge graph with the model output data involves adding new entities, relationships, or attributes to the graph based on the predictions or recommendations from the machine learning model. While Excel tables are useful for visualizing data, updating a knowledge graph typically involves using a graph database and a graph query language or an API.
However, I'll illustrate the changes in the knowledge graph based on the previous example using tables to help you understand the concept.
Consider the movie recommendation example where the machine learning model predicted genres for new movies. Here's the output data:
Machine Learning Model Output: Movie ID Movie Title Predicted Genre 5 Movie E Genre 1 6 Movie F Genre 2 7 Movie G Genre 1 8 Movie H Genre 2
To update the knowledge graph with this data, we'll create new entities for the movies and relationships connecting them to their predicted genres. Assuming that the graph is stored in a graph database like Neo4j, you would use the Cypher query language to perform the updates. In Excel table format, the updated knowledge graph could look like this:
Movies (Updated): Movie ID Movie Title Genre Prediction 1 Movie A 2 Movie B 3 Movie C 4 Movie D 5 Movie E Genre 1 6 Movie F Genre 2 7 Movie G Genre 1 8 Movie H Genre 2
Genre-Movie Relationships (Updated): Relationship ID Movie ID Genre ID Relationship Type 1 1 9 Actual Genre 2 2 9 Actual Genre 3 3 10 Actual Genre 4 4 10 Actual Genre 5 5 9 Predicted Genre 6 6 10 Predicted Genre 7 7 9 Predicted Genre 8 8 10 Predicted Genre
In this example, we've added the new movies (Movie E, F, G, H) with their genre predictions to the "Movies" table and created new relationships in the "Genre-Movie Relationships" table connecting the new movies to their predicted genres.
Keep in mind that Excel tables are used here only for illustration purposes. In practice, you would use a graph database and a graph query language or API to update the knowledge graph with the machine learning model's output data. User what's the "Validate and maintain the knowledge graph: Validate that the new entities and relationships are correct, maintain data consistency, and regularly update the graph with new machine learning output data". please explain with a example by excel table. ChatGPT
"Validate and maintain the knowledge graph" means ensuring the accuracy and consistency of the data in the knowledge graph, especially when new information is added or updated based on the output of a machine learning model. In practice, this process usually involves using a graph database and various validation techniques.
For the sake of explanation, let's assume that we have a knowledge graph stored in Excel tables for a movie recommendation system. We have already updated the graph with new movies and their predicted genres from a machine learning model. The updated tables look like this:
Movies (Updated): Movie ID Movie Title Genre Prediction 1 Movie A 2 Movie B 3 Movie C 4 Movie D 5 Movie E Genre 1 6 Movie F Genre 2 7 Movie G Genre 1 8 Movie H Genre 2
Genre-Movie Relationships (Updated): Relationship ID Movie ID Genre ID Relationship Type 1 1 9 Actual Genre 2 2 9 Actual Genre 3 3 10 Actual Genre 4 4 10 Actual Genre 5 5 9 Predicted Genre 6 6 10 Predicted Genre 7 7 9 Predicted Genre 8 8 10 Predicted Genre
To validate and maintain the knowledge graph, you would:
Check for data consistency: Ensure that the data in the graph is consistent, such as verifying that all movie IDs in the "Genre-Movie Relationships" table exist in the "Movies" table.
Verify the correctness of new entities and relationships: Validate the accuracy of the machine learning model's predictions or recommendations, possibly by comparing them to ground truth data or through manual evaluation by domain experts. In our example, you could verify if the predicted genres for the new movies (Movie E, F, G, H) are accurate.
Monitor and update the graph regularly: Periodically retrain the machine learning model with the latest data and update the knowledge graph with the new output data to ensure the graph remains up-to-date and accurate. In our example, you could retrain the genre prediction model regularly to improve its performance, update the "Movies" and "Genre-Movie Relationships" tables with new predictions, and validate the updated graph.
While Excel tables are used here for illustrative purposes, keep in mind that maintaining a knowledge graph typically involves using a graph database and specialized tools or techniques for validation and consistency checks.

Map Model Output to Entities and Relationships: Identify how the machine learning output data maps to entities and relationships in the knowledge graph. This involves determining how the predicted or recommended data can be integrated into the graph structure, such as creating new relationships between existing entities or adding new entities based on the output data.
Update Knowledge Graph: Use an appropriate method like a graph query language or API to update the knowledge graph with new entities, relationships, or attributes based on the machine learning output data. This involves adding or modifying the graph's structure to reflect the insights gained from the machine learning model.
Validate and Maintain Knowledge Graph: Validate that the new entities and relationships are correct, maintain data consistency, and regularly update the graph with new machine learning output data. This step is essential to ensure the knowledge graph remains accurate and up-to-date, as well as to track the performance of the machine learning model over time.
Periodic Retraining and Updating: Retrain the machine learning model periodically with the latest data and update the knowledge graph with the new output data. This helps ensure the model's performance improves over time and the graph stays current with the latest insights or recommendations from the model.

Copy and paste the code above into the editor to see the flowchart visualizing the process of combining knowledge graph and machine learning with a focus on Excel tables. User please give a example format for extract relevant data and machine learning input by excel tables ChatGPT
In this example, let's assume we have a knowledge graph for a movie recommendation system, and we want to use machine learning to predict movie genres. We'll start by extracting relevant data from the knowledge graph and preparing it as input for the machine learning model. Here are example Excel tables for each step:
Knowledge Graph Data (Entities and Relationships): Entity Type Entity ID Entity Name Movie 1 Movie A Movie 2 Movie B Movie 3 Movie C Genre 4 Genre 1 Genre 5 Genre 2 Relationship Type Relationship ID From Entity ID To Entity ID belongs_to_genre 1 1 4 belongs_to_genre 2 2 4 belongs_to_genre 3 3 5
Extract Relevant Data (Movie-Genre Pairs): Movie ID Movie Name Genre ID Genre Name 1 Movie A 4 Genre 1 2 Movie B 4 Genre 1 3 Movie C 5 Genre 2
Prepare Machine Learning Input (Features and Labels): Movie ID Feature 1 Feature 2 ... Feature N Genre ID 1 0.23 0.45 ... 0.67 4 2 0.12 0.34 ... 0.78 4 3 0.56 0.89 ... 0.43 5
In this example, the "Extract Relevant Data" table shows the extracted movie-genre pairs, which are relevant for predicting movie genres. The "Prepare Machine Learning Input" table includes the movie features (e.g., numerical representations of movie characteristics) and genre labels (genre IDs) needed to train the machine learning model.
Remember that the actual features used for the machine learning model would depend on the specific problem and dataset, and the example provided here is for illustration purposes only. User please explain why Extract Relevant Data (Movie-Genre Pairs) is four columns , but Prepare Machine Learning Input (Features and Labels) is N columns ChatGPT
The difference in the number of columns between the "Extract Relevant Data" and "Prepare Machine Learning Input" tables is due to the transformation of the data to be suitable for machine learning algorithms.
In the "Extract Relevant Data" table, the movie-genre pairs are represented in a human-readable format, with four columns: Movie ID, Movie Name, Genre ID, and Genre Name. This format is useful for understanding the relationships between movies and genres, but it's not suitable for most machine learning algorithms, which typically require numerical input features.
The "Prepare Machine Learning Input" table, on the other hand, has N columns (where N is the number of features used for the machine learning model). In this table, the movie data is transformed into a set of numerical features (Feature 1, Feature 2, ..., Feature N) that represent various characteristics of the movies. These features could be derived from metadata, text analysis, or other data sources related to the movies.
Machine learning algorithms use these numerical features to learn patterns and make predictions. The additional column for the Genre ID serves as the label, or the target variable, which the model will predict based on the input features.
In summary, the "Extract Relevant Data" table presents the data in a human-readable format, while the "Prepare Machine Learning Input" table transforms the data into numerical features and labels, which are suitable for training and evaluating machine learning models. User So that meaning is like using one-hot encoding to transfer 4 columns to N columns ChatGPT
Yes, one-hot encoding is one way to transform categorical data, like movie genres, into numerical data suitable for machine learning algorithms. However, the example I provided earlier referred to the transformation of movie data into a set of numerical features, not specifically the transformation of genre labels using one-hot encoding. Let me clarify with an example.
One-hot encoding is usually applied to categorical variables, like the Genre column in the "Extract Relevant Data" table. If you want to one-hot encode the genre labels, the "Prepare Machine Learning Input" table might look like this:
Prepare Machine Learning Input (Features and Labels with One-Hot Encoding): Movie ID Feature 1 Feature 2 ... Feature N Genre 1 Genre 2 1 0.23 0.45 ... 0.67 1 0 2 0.12 0.34 ... 0.78 1 0 3 0.56 0.89 ... 0.43 0 1
In this table, the Genre ID column has been replaced with two new columns (one for each unique genre) that use one-hot encoding. Each genre now has a separate column, with a 1 indicating the presence of that genre and a 0 indicating its absence.
However, keep in mind that one-hot encoding is just one way to preprocess the data for machine learning algorithms, and it's mainly applicable to categorical variables. The transformation of movie data into numerical features (Feature 1, Feature 2, ..., Feature N) might involve other techniques, such as text analysis, feature scaling, or dimensionality reduction, depending on the specific problem and dataset. User please give a example format for Generate Model Output to be the Map Model Output to Entities and Relationships ChatGPT
After training the machine learning model, it will generate output data, such as predictions or recommendations. In the context of our movie recommendation system that predicts movie genres, let's assume we have a new set of movies for which the model will predict genres. Here's an example format for the "Generate Model Output" and "Map Model Output to Entities and Relationships" steps:
Generate Model Output (Predicted Genre IDs for New Movies): Movie ID Predicted Genre ID 4 4 5 5 6 4
In this table, the machine learning model has predicted genres for three new movies (Movie IDs 4, 5, and 6). The Predicted Genre ID column represents the genre ID predicted by the model for each movie.
Map Model Output to Entities and Relationships: Entity Type Entity ID Entity Name Movie 4 Movie D Movie 5 Movie E Movie 6 Movie F Relationship Type Relationship ID From Entity ID To Entity ID belongs_to_genre 4 4 4 belongs_to_genre 5 5 5 belongs_to_genre 6 6 4
In the "Map Model Output to Entities and Relationships" step, we create new entities for the movies and establish relationships between the movies and their predicted genres. In this example, Movie D and Movie F are predicted to belong to Genre 1 (Genre ID 4), and Movie E is predicted to belong to Genre 2 (Genre ID 5).
The new entities and relationships are then added to the knowledge graph, enriching the graph with the insights gained from the machine learning model. User Please use below table to be a knowledge graph by Mermaid code ChatGPT

Apologies for the mistake. I realize the issue is due to the formatting of the node labels. Let's use another approach to label the nodes and display the knowledge graph correctly. Here's the updated Mermaid code:
mermaid
graph LR A["Movie A (1)"] --> C["Genre 1 (4)"] B["Movie B (2)"] --> C D["Movie C (3)"] --> E["Genre 2 (5)"]
This Mermaid code should now work correctly in the Mermaid Live Editor. Copy and paste the code above into the editor to see the graph visualizing the knowledge graph data. User please use python code to be a UI to get below table:ovie ID Movie Name Genre ID Genre Name 1 Movie A 4 Genre 1 2 Movie B 4 Genre 1 3 Movie C 5 Genre 2 ChatGPT
To create a simple UI in Python for displaying the given table, you can use the tkinter library. Here's an example of how to do that:
python
import tkinter as tk
root = tk.Tk() root.title("Movie-Genre Table")
headers = ["Movie ID", "Movie Name", "Genre ID", "Genre Name"] for i, header in enumerate(headers): label = tk.Label(root, text=header, font=("Arial", 12, "bold")) label.grid(row=0, column=i)
data = [ [1, "Movie A", 4, "Genre 1"], [2, "Movie B", 4, "Genre 1"], [3, "Movie C", 5, "Genre 2"] ]
for i, row in enumerate(data): for j, cell in enumerate(row): label = tk.Label(root, text=cell, font=("Arial", 12)) label.grid(row=i+1, column=j)
root.mainloop()
This code creates a simple UI with a table displaying the given movie-genre data. You can run this code in your Python environment, and a window with the table will appear.
Note that you'll need to have the tkinter library installed. If you're using Python 3, it should already be included. If you have any issues with the library, try installing it using:
bash
pip install tk
Keep in mind that this is a very basic example, and there are many ways to improve the UI or add more functionality depending on your requirements. User how to make a query system with UI by Mermaid to get the below table :Movie ID Movie Name Genre ID Genre Name 1 Movie A 4 Genre 1 2 Movie B 4 Genre 1 3 Movie C 5 Genre 2 ChatGPT
Mermaid is a diagramming and charting tool and is not designed to create a query system or UI. Instead, you can create a simple UI using the tkinter library in Python and a basic query system that retrieves movie information based on user input. Here's an example of how to do that:
python
import tkinter as tk
def handle_query(): movie_id = int(entry.get()) if 1 <= movie_id <= len(data): result = data[movie_id - 1] result_label.config(text=f"Movie Name: {result[1]}, Genre ID: {result[2]}, Genre Name: {result[3]}") else: result_label.config(text="Movie ID not found")
data = [ [1, "Movie A", 4, "Genre 1"], [2, "Movie B", 4, "Genre 1"], [3, "Movie C", 5, "Genre 2"] ]
root = tk.Tk() root.title("Movie-Genre Query System")
label = tk.Label(root, text="Enter Movie ID:", font=("Arial", 12)) label.pack() entry = tk.Entry(root, font=("Arial", 12)) entry.pack()
button = tk.Button(root, text="Query", command=handle_query, font=("Arial", 12)) button.pack()
result_label = tk.Label(root, text="", font=("Arial", 12)) result_label.pack()
root.mainloop()
This code creates a simple UI with an input field for the user to enter a movie ID and a button to query the movie-genre data. When the user clicks the "Query" button, the program retrieves the corresponding movie information and displays it below the button.
To run this code, copy and paste it into a Python file and execute it in your Python environment. A window with the input field, button, and result display will appear.
Keep in mind that this is a very basic example, and there are many ways to improve the UI, add more functionality, or implement a more advanced query system, depending on your requirements. User What’s the benefit to make a combine system by knowledge graph and machine learning , if I just apply machine learning , I also can teach the goal. ChatGPT
Combining a knowledge graph with machine learning offers several benefits that may not be achievable by using machine learning alone. Some of these benefits include:
Rich contextual information: Knowledge graphs provide a structured representation of data and their relationships, capturing more context than a simple table or feature vector. This context can improve machine learning models by offering additional insights and allowing models to leverage relationships between entities.
Improved data quality: Knowledge graphs can help identify data inconsistencies, missing data, and outliers, which can negatively impact machine learning model performance. By maintaining a clean and well-structured knowledge graph, you can ensure that the data used for machine learning models is accurate and of high quality.
Explainability and transparency: Knowledge graphs can make it easier to understand and explain the outcomes of machine learning models, as they provide a clear representation of the relationships between different data entities. This can help you better understand the underlying reasons for a model's predictions or recommendations.
Data integration and interoperability: Knowledge graphs can help integrate data from different sources, making it easier to combine diverse datasets for machine learning tasks. This can lead to more comprehensive and accurate models, as they can draw upon a wider range of information.
Model improvement over time: As new information is added to the knowledge graph, machine learning models can be updated and refined, allowing them to improve their performance over time. This enables models to adapt to changing data and trends, ensuring they remain effective and relevant.
Transfer learning and multi-task learning: Knowledge graphs can facilitate transfer learning and multi-task learning, allowing you to leverage pre-existing knowledge from one domain or task to improve performance on another. This can lead to faster model training and better overall performance.
By integrating knowledge graphs with machine learning, you can harness the power of both techniques to build more robust, accurate, and insightful models. While using machine learning alone can be effective, the combination of these two approaches can lead to significant improvements in data quality, model performance, and explainability
