algebraic-topology

We cover some of the the most important concepts of algebraic topology in order to explore how deep neural networks operate in their hidden layers and why they are so amazingly efficient

classification_1

This code trains a neural network model to classify images of clothing using tf.keras

fake_news_detection

This project trains a Long Short Term Memory (LSTM) network to detect and classify fake news.

FFT

The Fast Fourier Transform With One Application In Audio Correction

manual-pruebas-de-hipotesis

Manual de pruebas de hipótesis en R

most_common_words_in_news

We create a function that takes the data from the csv file and prints the five classifications with a list of the x most repeated words for each classification.

random-forests-breast-cancer-prediction

We use the Breast Cancer Wisconsin Diagnostic Data Set to train and test the model that classifies whether a tumor with certain characteristics is a malignant or a benign tumor.

schrodinger

The Schrodinger equation and other cool physics concepts explained.

time-series-decomposition

Time series decomposition using pandas-datareader and dtw
