Projects
Bengali Character Recognition with Deep Learning
Spring 2020
Implemented a DenseNet architecture and trained from scratch with data augmentation and hyperparameter tuning to recognize handwritten bengali characters. Secured an accuracy of 92% with 1 GPU and 100 epochs of training.
Conditional Text Generator using Neural NLP
Spring 2020
Fine-tuned a GPT-2 language model to generate Amazon reviews like text conditioned on keyword and rating. Also fine-tuned a PPLM model for better sentiment control.
