PROJECTS

Predict Appliance Energy Consumption

Implemented different dimensionality reduction algorithms Random Forest, forward selection, backward elimination, PCA & ICA Developed regression and gradient decent algorithms from scratch by minimizing cost functions for different learning rates Support Vector Machines - Classified house consumption for various gamma & kernels (Linear, Polynomial, Gaussian, Sigmoid) K-means clustering - Implemented Elbow method to identify the no of clusters and predicted consumption for households Decision Tree - Explored different decision criteria (Entropy, Information gain, Gini index, Chi-Square) to observe change in accuracies and implemented tree pruning to avoid overfitting Artificial Neural Networks - Experimented with different activation functions (Tanh, Sigmoid, ReLU), various optimizer (Adam, SGD, AdaDelta), no of hidden layers and different number of neurons Using News to Predict Stock Movements Techniques – XGBoost, CatBoost Aggregated news & market data to anticipate performance of a stock by apt selection of features from sea of available attributes Object Detection with OpenCV Techniques- Convolutional Neural Network, MobileNet Collected images from internet and labelled data to train a CNN to build a face mask detector with 96% accuracy using Keras, Tensor flow and OpenCV. Integrated the model to a live video camera to be used in real-time applications which require face- mask detection for safety purposes due to the outbreak of Covid-19 EDUCATION
