04/17 – 11/21

Project: Precast Structure Compressive Strength.

  • Proposed Random Forest regressor model to predict the erected precast structures' compressive strength. Able to achieve RMSE 7.34.
  • Performed data preprocessing techniques. Used KNN imputer to handle missing values. Performed feature engineering and scaling on various features.
  • Experimented with various algorithm like Linear Regressor, Decision Tree, Support Vector, Naïve Bayes.
  • Model is in testing phase with our trusted clients. The proposed goal is to reduce time of concrete manufacturing by 17-22%.

Project: Sales Insight Dashboard For MEP Equipment.

  • Built a sales insight dashboard using Tableau which proved 10% cost saving on total spent. Saved 20% time of sales analysts by stopping manual data gathering.
  • Used AIMS Grid for project planning and defining purpose, stakeholders, success criteria, final result. Coordinated among stakeholders through RFI and Kick Off.
  • Performed ETL using MySQL and Tableau. Used star schema to define relations among customer, data, markets, product and transactions tables from Sales database.
  • Employed feature engineering on transaction table by adding new feature like normalized amount, profit and profit margin.

Project: Lead Qualifier

  • Identified the problem of leads being not converted to revenue. Bult a model that qualified leads to revenue. Performed deep analysis on company's leads data.
  • Involved in preprocessing, feature engineering, EDA and model building.
  • Built a XG Boost model with precision score of 0.72. Experimented with other ML models.
  • leads to revenue conversion increased by 11%. Helped marketing team to run campaign efficiently on target customers.

Project: Wholesale Store Sales Prediction Created a new Deep Learning based Hybrid model for Stock Prices prediction.

  • Developed a stacking model to help Store Managers predict their future sales and be able to take necessary upstream & downstream decisions to optimize for supply chain cost and customer experience.
  • Employed essential data pre-processing techniques. Analyzed pattern of store sales to capture the cyclic trend over different time period, relation with marketing campaigns, store demographics and nearby competitors.
  • Engineered features like- 'Total Competition Month, Total Promotion Year, Total Promotion Week, IsPromoMonth, Average Sales and Average Customers. Used One Hot Encoding to treat categorical features.
  • Used naïve forecasting as a benchmark model with 33% MAPE. Implemented a stacking model of Decision Tree Regressor, Random Forest Regressor and Light GBM to reduce MAPE to 18%. Used feature selection techniques to get important features.

Project: Sentiment Analysis of Tweets to Flag Negative Sentiments.

  • Built a binary-class Naive Bayes classifier to predict the sentiment associated with a particular tweet and obtained the F1 score of 0.79.
  • Employed essential text preprocessing techniques such as tokenization, regular expression, stop words removal and stemming to obtain clean tweets. Used Word Cloud to visualize and analyze the tweets.
  • Performed feature engineering on Sentiments and converted it into binary classification. Used word embedding and generated optimal document-word sparse matrix using TF-IDF Vectorizer by tuning parameters.
  • Experimented with multiple classification algorithms such as Multinomial Naive Bayes, Random Forest, XGBoost and SVC to compare with binary classification model.

Project: Book Recommendation System.

  • Developed a book recommendation system for customers using memory- based collaborative filtering by utilizing the description of book and user interests.
  • Engineered new feature- 'score to check the popularity and employed cosine distance to measure user-term and item-term similarities.
  • Created profiles for top active users by leveraging interaction strength with the recommended items and achieve test recall@5 of 42% and recall@10 of 53%.
  • Analyzed the solution for the cold start problem based on global and demographic specific book popularity and improved efficiency of the user recommendation engine.
