I'm a second year PhD student, working with Josephine Sullivan.

My broad area of research is self-supervised learning for satellite images. Currently, I'm investigating the effect of noisy positive pairs in domain-specific contrastive learning on the downstream task performance.

For classification, it's detrimental to teach a network that a dog is a cat if you want it to distinguish them later on. For segmentation, it seems like it's not detrimental to tell the network that a whole building and a destroyed building are the same. That's pretty unexpected.
Here's my poster I'm presenting on Tuesday at LPS22 about this: Link to poster.
