Neural Network developed during my Deep Learning Fundamentals Nanodegree at Udacity 2018. In this project, I created a simple neural network to use it to predict daily bike rental ridership.
This Bike-Sharing-Dataset has the number of riders for each hour of each day from January 1 2011 to December 31 2012. The number of riders is split between casual and registered, summed up in the cnt column. You can see the first few rows of the data above.
Below is a plot showing the number of bike riders over the first 10 days or so in the data set. (Some days don't have exactly 24 entries in the data set, so it's not exactly 10 days.) You can see the hourly rentals here. This data is pretty complicated! The weekends have lower over all ridership and there are spikes when people are biking to and from work during the week. Looking at the data above, we also have information about temperature, humidity, and windspeed, all of these likely affecting the number of riders. You'll be trying to capture all this with your model.
Thinks you have to install or installed on your working machine:
- Python 3.7
- Numpy (win-64 v1.15.4)
- Pandas (win-64 v0.23.4)
- Matplotlib (win-64 v3.0.2)
- Jupyter Notebook
- Torchvision (win-64 v0.2.1)
- PyTorch (win-64 v0.4.1)
Use the package manager pip or
miniconda or Anaconda to install your packages.
A step by step guide to install the all necessary components in Anaconda for a Windows-64 System:
conda install -c conda-forge numpy
conda install -c conda-forge pandas
conda install -c conda-forge matplotlib
pip install torchvision
conda install -c pytorch pytorchYour_first_neural_network.ipynb
This jupyter notebook describe the whole project from udacity, from the beginning to the end.
The whole project is located in the jupyter notebook file Your_first_neural_network.ipynb and it's include the training an the prediction part. The neural network is implemented in the file my_answer.py and used from the jupyter notebook.
This is actually my best version of bike-sharing-patterns. The next steps will be:
- do some experiments with the neural network to change the hyperparameters / hidden units / optimizer / structure of fully connected layers, ...
- convert the image classifier algorithm to keras
- convert the image classifier algorithm to fast.ai
- I will see what's comming next ...
