arXiv Paper Analyzes Resolution-Independent Encoder-Decoder Operator Learning

A new arXiv preprint examines how encoder-decoder architectures for operator learning behave as the discretization of training data changes. The authors use limiting kernels to show that the induced operator-valued kernel can be analyzed independently of the chosen finite-dimensional resolution. The work targets reliable operator learning when only finite-dimensional representations of function data are available.

arXiv paper targets lower-tail calibration of Gaussian processes for Bayesian optimization

An updated arXiv preprint proposes a goal-oriented approach to calibrating the lower tail of Gaussian process predictive distributions, which Bayesian optimization uses to choose where to evaluate costly objective functions. The abstract notes that kernel and hyperparameter choices strongly shape these predictions. The submission is a replacement version (v2) of an earlier preprint.

Monograph Maps Connections Between Gaussian Processes and Kernel Hilbert Spaces

A newly updated arXiv monograph examines the relationship between two kernel-based machine learning traditions: probabilistic modeling with Gaussian processes and non-probabilistic methods built on reproducing kernel Hilbert spaces. The work lays out the mathematical connections and equivalences between the two approaches, providing a unified theoretical treatment of positive definite kernel techniques.

Balanced k-shot sampling causes exact degeneracy in discriminant analysis on LLM embeddings

A new arXiv paper proves that balanced k-shot sampling, which draws exactly k labeled examples per class, induces an exact and provable degeneracy in a family of small-sample discriminant estimators. The result concerns kernelized linear discriminant methods applied to LLM embeddings, where the within-class scatter operator breaks down under equal per-class sample counts. The finding carries practical consequences for few-shot classification pipelines that rely on embeddings from large language models.

Kernel-Based Modular Discriminant Analysis Framework Proposed for Small-Sample Learning

A newly posted arXiv paper introduces a kernel-based modular discriminant analysis framework targeting the small-sample-size problem in machine learning, where labeled data are scarce due to cost, accessibility, or ethical constraints. The work addresses limitations of existing methods that struggle to perform reliably when training examples are limited.
