Accomplishments
- Book Recommender System AlmaBetter Verified Project 09/2021, Tags: EDA, Feature Engineering, KNN, Collaborative Filtering, Content Based Filtering, NLP, TFIDF, SVD, Recall Developed different recommender systems for recommendations of books to users, using explicit and implicit ratings of books and popularity-based, collaborative, and content-based filtering.
- Extracted new information of the books using Google API and vectorized it using TFIDF.
- Used models like KNN and Singular Value Decomposition to make recommendations based on user-user and item-item similarities.
- Obtained a recall of 90% using collaborative filtering.
- Bankruptcy Prediction AlmaBetter Verified Project 09/2021, Tags: EDA, Feature Selection, Quasi, L1 Regularization, Random Forest , PCA, Isolation Forest, Resampling, Easy Ensemble, Gaussian Naive Bayes, XGBoost Developed a model which captures the bankruptcy patterns among the companies in industries.
- Reduced the features using different techniques like Random Forest Feature Importance, p_values, VIF, Quasi Feature Selection and L1 Regularization.
- Built multiple models with the combinations of these features considering different use cases.
- Built a Random Forest Model which gave a recall of 94%, a KNN model which gave a precision of 74%, and a Gaussian Naive Bayes Model which gave an F1 score of 51%.
