Back to the Definition: Estimating Step-Level Advantages via Trajectory Graphs for Agentic Reinforcement Learning

A Graph-based Faithful sTep-level credit-assignment framework (GRAFT) that grafts all rollout trajectories into a trajectory graph, recovering node state-values via Bellman iteration on the graph, and assigning credit to each edge by the node value difference is proposed.

What a Crossref record shows when a paper is retracted: one month of retraction deposits (v2)

**A field-level audit of one month of retraction deposits (v2)** Author: Trafalgar Law (independent). Data pulled from the public Crossref REST API on 2026-09-23. Sample and reproduction query included. This is a metadata audit, not an accusation against any publisher or author. ## Why On 2026-09-19 the record for a fi...

Simultaneous Latent Budget Trees for Stratified Classification

Simultaneous Latent Budget Trees, a probabilistic machine learning framework for classification trees in the presence of a stratification factor such as a temporal, spatial, or demographic variable, acting as a control variable or potential confounder, is introduced.

The Truncation Blind Spot: How Decoding Strategies Systematically Exclude Human-Like Token Choices

Probability-floor samplers substantially narrow the blind spot, demonstrating that the choice of truncation criterion matters for retaining human-used tokens and motivate decoding methods that preserve contextually appropriate low-probability choices while maintaining generation quality.

Regular Fourier Features for Nonstationary Gaussian Processes

This work discretizes the spectral representation directly, preserving the correlation structure among spectral weights without requiring probability assumptions, and yields an efficient low-rank approximation that is positive semi-definite by construction and consistent under mild regularity conditions.

InsurTech innovation using natural language processing

This paper applies various NLP techniques to demonstrate feature de-biasing, feature compression, and industry classification in the commercial insurance context to show that NLP is not merely a supplementary tool but a foundational element of modern, data-driven insurance analytics.

Role of scrambling and noise in temporal information processing with quantum systems

A quantum reservoir processing framework that captures a broad range of physical computing models with quantum systems and it is numerically demonstrated that exponential concentration can still exist even with a physical reservoir such as an Ising model whenever the reservoir operates in a quantum-chaotic phase.

Statistical Properties of Deep Neural Networks with Dependent Data

This paper develops theory for deep neural network (DNN) estimators under dependent data. To provide theory applicable to a variety of DNN-based estimators, I first establish nonasymptotic probability bounds on the theoretical and empirical $\mathcal{L}^{2}$-errors of nonparametric sieve estimators for a general class...

FastManly: An EM-Gradient Algorithm for Manly Mixture Models

A faster implementation of mixtures of Manly transformations is proposed, which uses Newton's method for optimization in an EM gradient algorithm instead of Nelder-Mead in a traditional EM.

Energy-guided Recursive Model

Recursive models show promise on reasoning and language tasks, yet their test-time scaling lacks a principled criterion for selecting trajectories or determining recurrent depth. We introduce \textbf{Energy-guided Recursive Model (ERM)}, which uses Hopfield-type memories of valid local and global structures to assign i...

A lift for input-convex neural net training

The lift is proposed, which replaces the free latent weight by a learnable slack plus an unconstrained network---the body---that takes a permutation-invariant summary of the training batch as input and couples to the gradient formed on it.
