VectorDefense: Vectorization as a Defense to Adversarial Examples
Training deep neural networks on images represented as grids of pixels has brought to light an interesting phenomenon known as...
I'm interested in (1) understanding the weaknesses, behaviors, and inner-workings of AIs; and (2) making these systems more trustworthy and explainable.
Below are selected projects in Vision, NLP, Explainable AI, and HCI where I'm a lead contributor (the first or senior author).
