Memory Efficient Experience Replay for Streaming Learning

1 code implementation16 Sep 2018 Tyler L. Hayes, Nathan D. Cahill, Christopher Kanan

We find that full rehearsal can eliminate catastrophic forgetting in a variety of streaming learning settings, with ExStream performing well using far less memory and computation.

Compassionately Conservative Balanced Cuts for Image Segmentation

no code implementations CVPR 2018 Nathan D. Cahill, Tyler L. Hayes, Renee T. Meinhold, John F. Hamilton

The Normalized Cut (NCut) objective function, widely used in data clustering and image segmentation, quantifies the cost of graph partitioning in a way that biases clusters or segments that are balanced towards having lower values than unbalanced partitionings.

Semi-Supervised Normalized Cuts for Image Segmentation

no code implementations ICCV 2015 Selene E. Chew, Nathan D. Cahill

Since its introduction as a powerful graph-based method for image segmentation, the Normalized Cuts (NCuts) algorithm has been generalized to incorporate expert knowledge about how certain pixels or regions should be grouped, or how the resulting segmentation should be biased to be correlated with priors.
