My Projects - Nathaniel Bagchee

Python Projects

• Several manual and sklearn implementations of Perceptron, Naive Bayes, KMeans/GMM
• Neural Network Backpropagation for a simple neural network
• Blackjack Simulator to simulate the effectiveness of a specific online AI blackjack card counter, can be used to test other strategies as well
• A small neural language model (MLP)
  • Uses nltk library to load corpuses for training/validation/test data
  • Creates embeddings for words (how similar/correlated words are to each other)
  • Predicts the next word from the previous two words embeddings
  • Generates random sentences based on what the model learned during training

Swift Project

• Contributed to a spend management software project for iOS devices, below are the things that I built for the project:
  • Created ways for users to sign in (email/password or Google) and have their data attached to their user profile
  • Implemented a way to crop images and zoom in/out of images
  • Built a way extract the text using OCR and then created regex parsing rules to parse the date, store name, and totals from reciepts
  • Built and labeled a dataset and trained a multinomial logistic regression classifier on it to classify whether items were truly items or not
  • Currently familiarizing myself with Solidity to implment a way to write the receipt data to a smart contract on the blockchain

C Project

• Created a web crawler which extracts all the URL's off of a webpage and filters out the URL's containing hrefs
  • Uses various data structures like sets, hashtables, and a bag

C++ Project

• Created an AVLTree data structure from scratch in C++
