This repository contains implementation of various deep learning and machine learning algorithms in Python. Different library/packages will be used for the implementations like TensorFlow, Keras, PyTorch, Scikit-Learn, etc.

Note: This repository is under constant development and new implementations are being added regularly.

1. The jupyter notebook neural_net_from_scratch.ipynb contains the raw implementation in python for a basic Multilayer Perceptron.
2. The python script neural_net_from_scratch.py is a cleaner version of the notebook version.
3. The jupyter notebook tensorflow_mlp_regression.ipynb contains a tensorFlow implementation of a Multilayer Perceptron with an example using regression on California housing dataset from the scikit-learn library.
4. The jupyter notebook tensorflow_mlp_classification.ipynb contains a tensorFlow implementation of a Multilayer Perceptron with an example using classification on the MNIST dataset.

1. The script rbm_impl.py contains a basic implementation of a restricted boltzmann machine in python using only numpy.

1. The jupyter notebook linear_regression_scratch.ipynb contains basic implementation of linear regression in python using numpy on a randomly generated dataset. The optimization is done using full-batch gradient descent.
2. The jupyter notebook linear_regression_tensorflow.ipynb contains an implementation of linear regression in python using TensorFlow on a randomly generated dataset. The optimization is done using GradientDescentOptimizer from TensorFlow.

1. The jupyter notebook logistic_regression_scratch.ipynb contains basic implementation of logistic regression in python using numpy using the iris dataset. Two of the linearly inseparable species are combined together into one category. The optimization is done using full-batch gradient descent.
2. The jupyter notebook logistic_regression_tensorflow.ipynb contains an implementation of logistic regression in python using TensorFlow on the iris dataset. The optimization is done using GradientDescentOptimizer from TensorFlow.
3. he jupyter notebook logistic_regression_keras.ipynb contains a Keras implementation of logistic regression on the iris dataset. The optimization is done using Stochastic Gradient Descent.

1. The jupyter notebook decision_trees_sklearn.ipynb contains an implementation of the decision tree algorithm in Python using scikit-learn. The iris dataset is used to make a prediction using decision trees.
2. The jupyter notebook decision_trees_scratch.ipynb contains an implementation of the decision tree algorithm in Python from scratch using numpy. The Spotify song attribute dataset is used to make a prediction using the decision trees and compared with the scikit-learn implementation.

This repository contains the implementation of machine learning and deep learning algorithms from scratch as well as using different libraries like Keras, TensorFlow, PyTorch, etc. The goal is to have a single resource where people can find all kinds of possible implementations of basic algorithms in ML and DL so that this becomes a standard reference for base models and projects involving the use of these algorithms.

1. Fork the repository.
2. Add the implementation of the algorithm with a clearly defined filename for the script or the notebook.
3. Test the implementation thoroughly and make sure that it works with some dataset.
4. Add a link with a short description about the file in the README.md.
5. Create a pull request for review with a short description of your changes.
6. Do not forget to add attribution for references and sources used in the implementation.
