H-SPLID: HSIC-based Saliency Preserving Latent Information Decomposition

Lukas Miklautz, Chengzhi Shi, Andrii Shkabrii +5

We introduce H-SPLID, a novel algorithm for learning salient feature representations through the explicit decomposition of salient and non-salient features into separate spaces. We…

Learning Set Functions with Implicit Differentiation

Gözde Özcan, Chengzhi Shi, Stratis Ioannidis

Ou et al. (2022) introduce the problem of learning set functions from data generated by a so-called optimal subset oracle. Their approach approximates the underlying utility functi…
