Customer Churn Prediction Model- Built a machine learning classification model using machine learning using many classification techniques like Logistic Regression, Random Forest and Boosting techniques to calculate the probability of each customers from the network using the past data and attributes of more than 3 million customers. --The overall precision of model was ~95% and churn rate was reduced from 2% to 0.95%. 2.Created several simple as well as complex machine learning models like Linear Regression, Logistic Regression, NLP, PCA. Neural Network, SVM etc 3.Time series forecasting models : Arima, Auto Arima, bats, tbats, prophet, ets etc, 4. Natural Language Processing: LDA, TF-IDF, Bag of words, N-gram
