An Illusion of Progress? Assessing the Current State of Web Agents

arXiv:2504.01382v4 Announce Type: replace Abstract: As digitalization and cloud technologies evolve, the web is becoming increasingly important in the modern society. Autonomous web agents based on large language models (LLMs) hold a great potential in work automation. It is therefore…

Is Supervised Learning Really That Different from Unsupervised?

arXiv:2505.11006v3 Announce Type: replace Abstract: We demonstrate how supervised learning can be decomposed into a two-stage procedure, where (1) all model parameters are selected in an unsupervised manner, and (2) the outputs y are added to the model, without changing…

Enjoying Non-linearity in Multinomial Logistic Bandits

arXiv:2507.05306v2 Announce Type: replace Abstract: We consider the multinomial logistic bandit problem, a variant of where a learner interacts with an environment by selecting actions to maximize expected rewards based on probabilistic feedback from multiple possible outcomes. In the binary…

An Empirical Analysis of the Laplace and Neural Tangent Kernels

arXiv:2208.03761v2 Announce Type: replace Abstract: The neural tangent kernel is a kernel function defined over the parameter distribution of an infinite width neural network. Despite the impracticality of this limit, the neural tangent kernel has allowed for a more direct…

A Minimalist Bayesian Framework for Stochastic Optimization

arXiv:2509.07030v2 Announce Type: replace-cross Abstract: The Bayesian paradigm offers principled tools for sequential decision-making under uncertainty, but its reliance on a probabilistic model for all parameters can hinder the incorporation of complex structural constraints. We introduce a minimalist Bayesian framework…

Longitudinal Flow Matching for Trajectory Modeling

arXiv:2510.03569v2 Announce Type: replace-cross Abstract: Generative models for sequential data often struggle with sparsely sampled and high-dimensional trajectories, typically reducing the learning of dynamics to pairwise transitions. We propose Interpolative Multi-Marginal Flow Matching (IMMFM), a framework that learns continuous stochastic…
