Music Genre Classifier
-
- Identifying genres of songs is an important problem in music information retrieval.
- Used different machine learning techniques - Gaussian Mixture Modeling, Multi-class SVM, sparse representation classification to classify songs on the basis of their genre.
- Used leave-one-out cross validation for evaluation and compared the validation rate across classifiers.Other creators -
Collaborative Filtering with Attribution Error
-
Generative probabilistic modeling (tweaked LDA jointly modeling user preferences and sensor noise) to resolve ambiguity in noisy user-item interactions (imprecise mobile GPS check-in data), infer latent user preferences, and generate personalized recommendations (new places for you to visit).

Cloud 9 - Intelligent Dating App
-
Cloud 9 is an end-to-end dating application that helps sets up potential dates with matches through Tinder, uses NLP against the chat text to infer the match’s interests, preferences, time availability, etc. and helps schedule a date night at a great venue at a perfect time by leveraging Yelp and Google Calendar APIs, and calls an Uber for you when it’s time to leave for the date.

Automated Skill-Validation and Testing (SaaS prototype)

Built a web-based skill testing service POC that seeks to eliminate the subjectivity of resumes and false positives and negatives in the screening/hiring process. We provide relevant, standardized skill tests, allow independent, approved test-creators to auto-conduct their tests, and provide sophisticated candidate and test analytics.

Built a web-based skill testing service POC that seeks to eliminate the subjectivity of resumes and false positives and negatives in the screening/hiring process. We provide relevant, standardized skill tests, allow independent, approved test-creators to auto-conduct their tests, and provide sophisticated candidate and test analytics. The website was implemented using the MEAN stack, and we worked on the business model and disruptive edge, drew up financial projections, performed competitive analysis, iterated on product design+dev, and created a full-fledged business plan over the course of the semester. Our work received the top grade for the Principles of Innovation and Entrepreneurship course at Columbia University.

Evaluation of iOS App Development Frameworks
-
- Compared development of iOS apps in Swift and Xamarin, i.e. native vs non-native frameworks.
- Analyzed various API and system level calls' effects on app performance, fluidity, and user experience. -
Colgate Calendar
-
Students at Colgate are usually overwhelmed with campus event emails and have a hard time finding events that match their individual interests. Colgate Calendar allows students to keep a list of keywords as filter criteria, and to only be notified of campus events matching their individual criteria.
