Projects

Adaptive Activation Function

The goal is to create an activation function whose performance on Computer Vision benchmarks is at par with models employing higher number of parameters.
Code to paper that lead to inspiration:

Performance of our Activation Function:
Test Accuracy: 99.61%   Test Loss: 0.028

Loss and Accuracy on MNIST Validation Data

Development of a Self Driving Car

Final Year Major Project

The main objective is to develop a fairly accurate distance estimation method that works on both common and ad-hoc objects. The additional challenge is to predict these distances using low-quality stereo images.
