Information Entropy-Based Attribute Reduction for Incomplete Set-Valued Data
IEEE Access, 2022 This paper investigates attribute reduction for incomplete set-valued data based on information entropy. The similarity degree between information values on a conditional attribute of an incomplete set-valued decision information system (ISVDIS) is first

Towards Computing Attributions for Dimensionality Reduction Techniques
Bioinformatics Advances, 2023 AbstractWe describe the problem of computing local feature attributions for dimensionality reduction methods. We use one such method that is well established within the context of supervised classification – using the gradients of target outputs with respect to the inputs – on the popular dimensionality reduction technique t-SNE, widely used in ...

Effective Hamiltonians with Relativistic Corrections I: The Foldy--Wouthuysen transformation versus the direct Pauli reduction [PDF]
, 1993 Two different methods of obtaining ``effective $2\times 2$ Hamiltonians'' which include relativistic corrections to nonrelativistic calculations are discussed, the standard Foldy--Wouthuysen transformation and what we call the ``direct Pauli reduction''.

Coevolutionary Fuzzy Attribute Order Reduction With Complete Attribute-Value Space Tree [PDF]
IEEE Transactions on Emerging Topics in Computational Intelligence, 2021 Since big data sets are structurally complex, high-dimensional, and their attributes exhibit some redundant and irrelevant information, the selection, evaluation, and combination of those large-scale attributes pose huge challenges to traditional methods. Fuzzy rough sets have emerged as a powerful vehicle to deal with uncertain and fuzzy attributes in
