Pytorch Influence Functions

Determining which images have the greatest positive and negative impact on a Deep Neural Network model’s predictions. Link to Github repository Using PyTorch to Identify Model Influences This project is based on the nimarb reimplementation of Influence Functions from the ICML2017 best paper: Understanding Black-box Predictions via Influence Functions by Pang Wei Koh and Percy Liang. The reference implementation can be found here: link. The Dataset The project makes use of the CIFAR-10 image dataset, which consists of 50,000 training images and 10000 test images in 10 classes.

Pneumonia X-ray

Link to Github repository Chest x-ray image of normal lungsThis project involves building a deep neural network that trains on a large dataset for classification on a non-trivial task. In this case, the task is using x-ray images of patients to classify whether or not they have pneumonia. The Dataset The dataset originates from Kermany et al. on Mendeley. The particular subset used for this project is sourced via Kaggle.

Online News Prediction

Link to Github repository Objectives Create a classification model. Determine which features are best able to predict how often an online article will be shared. Data Set This dataset was acquired from the University of California, Irvine’s Center for Machine Learning and Intelligent Systems archive (https://archive.ics.uci.edu/ml/datasets/Online+News+Popularity#). Data references articles published by Mashable (www.mashable.com).
