In this research project it has been discovered that the interaction between selectivity and the average activity of neurons provides a more accurate prediction of ablation performance deficits in groups of neurons across AlexNet, VGG16, MobileNetV2, and ResNet101.
The primary objective of social neuroscience is to uncover neural mechanisms that underpin social interactions. Researchers have employed various analytical techniques to pinpoint brain regions responsive to social and nonsocial stimuli. Nonetheless, validating these findings necessitates investigating the impact of lesions on these identified brain areas. Unfortunately, such studies are impractical with human participants and not ideally suited to animal behavior. Therefore, this project addresses the validation of several analytical methods in identifying groups of neurons crucial to social functions by examining the effects of targeted lesions in an artificial neural network (ANN).
Detecting brain regions associated with particular cognitive functions, such as visual processing, can pose challenges. To address this, the project introduces modules designed for ablating pre-trained neural network models using PyTorch.
In this project, PyTorch is utilized to generate activations for all units within any layer of a deep learning model. As an illustration, the Fairface model is used, and the resulting activations are saved in a CSV file for further analysis.
Effective knowledge discovery from newspapers, to comprehend the progression of specific events or identify analogous occurrences from the past, presents a significant and formidable challenge. This project focuses on enhancing topic tracking and clustering similar subjects to facilitate a comparative analysis of topic evolution among various groups. The outcome of this endeavor holds vital importance in opinion and trend analysis.

This project is my attempt on Task 4 at SemEval-2022, which was focused on detecting Patronizing and Condescending Language (PCL) towards vulnerable communities. In this project, I built a BERT sequence classifier and used PyTorch to fine-tune it.
The Tamil Speech Synthesis system is built upon Google’s Tacotron model, utilizing keithito’s implementation available here.
