Customized Adversarial Image Generator - 2018

The goal of this project was to implement fast and efficient Customized Adversarial Image Generator which can generate adversarial images for MNIST dataset.

The User has the option to specify the input image and the target class, the perturbed input image which will be classified as target class will be produced.
Implemented a variation of Fast Gradient Sign Method (FGSM) algorithm to perturb the input image.
The Perturbed image which will be indistinguishable to input image by Human eye are produced.

Credit Card Fraud Detection - 2018

The goal of this project was to predict whether a given credit card transaction is fradulent or not using anomaly detection algorithm.

Used multivariate gaussian distribution to model the probability density function, which is then used to flag whether a transaction is fradulent or not.
Used Feature engineering to remove the features that didn't have much impact in modeling the density function.
Dataset source: Kaggle (https://www.kaggle.com/mlg-ulb/creditcardfraud)
