SelfTune is an RL framework that enables systems and service developers to automatically tune various configuration parameters and other heuristics in their codebase, rather than manually-tweaking, over time in deployment. It provides easy-to-use API (Python, C# bindings) and is driven by bandit-style RL & online gradient-descent algorithms.

This is a custom implementation of a logistic regression model in Python, created from scratch. The model uses gradient descent optimization to learn the optimal weights and bias for binary classification tasks. It also includes L2 regularization to prevent overfitting, with the regularization strength controlled by the lambda hyperparameter.

In this project we will be using the publicly available and Kaggle-popular LendingClub data set to train Linear Regression and Extreme Gradient Descent Boosted Decision Tree models to predict interest rates assigned to loans. First, we will clean and prepare the data. This includes feature removal, feature engineering, and string processing.There are several entries where values have been deleted to simulate dirty data. Then, we will build machine learning models in Python to predict the interest rates assigned to loans. We will evaluate our models' performances using the root mean squared error (RMSE) metric and compare our models' results.

In recent years, speech emotion recognition is playing a vital role in today’s digital world. In our project, we considered RAVDESS Dataset for training the model. We considered 10 different Machine Learning Algorithms to find out which is the best algorithm among those by considering their accuracies. After that, we cleaned the dataset by applying mask function to remove unwanted background noise, so that we can increase the accuracy and again applied all 10 algorithms on this clean speech dataset to verify which is the best algorithm. Finally, by using that algorithm’s model, we tested a sample audio file to predict its emotion. KEYWORDS : Python, Librosa, Scikit-learn, Soundfile, Pyaudio, RAVDESS dataset, MLPClassifier, Logistic Regression, Naive Baye’s, K-Neighbor Classifier, XGB, LightGBM, Random Forest, Decision Tree, Stochastic Gradient Descent, Support Vector Machine, Jupyter Notebook.

This program implements linear regression from scratch using the gradient descent algorithm in Python. It predicts car prices based on selected features and uses a dataset of cars with their respective prices.
These are some popular Machine Learning Algorithms which I have implemented with some data sets. These include implementation of Linear Regression(multi variate), Gradient descent for Logistic and Linear Regression, Decision Trees, Random forests, Naive Bayes, KNN Implementation form scratch, SVM as a multiclass classifier, PCA implementation. They all are written in python 3.5 .
