A Fresh Look at Generalized Category Discovery through Non-negative Matrix Factorization

arXiv.org
Generalized Category Discovery (GCD) aims to classify both base and novel images using labeled base data. However, current approaches inadequately address the intrinsic optimization of the co-occurrence matrix $\bar{A}$ based on cosine similarity ...

Causal Order Discovery based on Monotonic SCMs

arXiv.org
In this paper, we consider the problem of causal order discovery within the framework of monotonic Structural Causal Models (SCMs), which have gained attention for their potential to enable causal inference and causal discovery from observational data ...

Modular Construction and Optimization of the UZP Sparse Format for SpMV on CPUs

Proceedings of the ACM on Programming Languages
Sparse data structures are ubiquitous in modern computing, and numerous formats have been designed to represent them. These formats may exploit specific sparsity patterns, aiming to achieve higher performance for key numerical computations than more ...
