• Responsible for binary classification of Sleep/Awake using 9 different smartphone sensor time series data and Fitbit data gathered using AWARE Framework for 120 users.
• Engineered features from raw sensor data into various descriptive statistics such as mean, standard deviation, count, percentiles, and so on
• Aggregated them in 3 different time windows (10/30/60 minutes) for Sleep prediction and data analysis.
• Preprocessed data by resampling and joining Fitbit sleep data with engineered features, dropping features/tuples with high nullity, Imputing/interpolating features to eliminate nullity, and visualizing tables for data.
• Implemented a time-table like data imputation method that assigns and updates average values for various sensors throughout the day in the respective time-windows that captures cyclical user behavior.
• Created a pipeline for tuning various classifier model hyper parameters which consisted of oversampling(SMOTE) on training data, scaling features, and GridSearch with K-Fold Cross Validation on Training set.
