Domain-Filtered Knowledge Graphs from Sparse Autoencoder Features

John Winnicki, Abeynaya Gnanasekaran, Eric Darve ยท 2026

Sparse autoencoders (SAEs) extract millions of interpretable features from a language model, but flat feature inventories aren't very useful on their own. Domain concepts get mixed with generic and weโ€ฆ

An Interactive Graphical Tool to Check the Coarray Continuity of Two-Fold Redundant Sparse Arrays (TFRSAs) Under Single Sensor Failures

Namya Malik, Ashish Patwari, Sangeetha N ยท 2026

Two-fold redundant sparse arrays possess inbuilt redundancy to tackle single-element failures. This property enables them to perform accurate direction of arrival (DOA) estimation even during single sโ€ฆ
