Darshana Graph: A Corpus for Comparative Indian Philosophy

Darshana Graph presents a corpus of over 125,000 text records from Hindu, Buddhist, and Jain philosophical sources. It includes a unique subset of 8,500 aligned records from 18 commentators across five schools, enabling cross-commentator comparison. The corpus supports stylometric analysis and a large language model pipeline that extracts philosophical concept relationships, revealing disagreement patterns and extraction limitations.

Reversal Q-Learning: A New Off-Policy RL Algorithm

Reversal Q-Learning (RQL) is a new off-policy reinforcement learning algorithm that trains a flow policy using prior data. By modeling flow refinement steps as actions in an expanded Markov decision process and applying virtual on-policy trajectories via reversal, RQL enables effective offline learning without backpropagation through time. Experiments on 50 robotic tasks show RQL achieves the best average performance among state-of-the-art flow-based offline RL methods.

Credit-in-Event: Re-Anchoring Event Credit in Dynamics Models

A new method called Credit-in-Event identifies and addresses temporal credit dilution in learned dynamics models. CREST, a label-free and training-free readout, re-anchors pooled representations by estimating transient event cores and applying event-versus-rest contrast, reducing out-of-distribution error across multiple systems and data types. Ablations confirm the improvement stems from event-core credit re-anchoring, not generic locality or stability priors.

Fairness in Graph Neural Networks via Laplacian Adaptation

A new framework modifies the Laplacian operator in graph diffusion to enhance fairness by incorporating subspace projections, spectral adjustments, and frequency-based filtering. The method leverages graph diffusion's smoothing properties to mitigate bias, with theoretical analysis and empirical validation on synthetic and real-world datasets showing improved fairness without significant computational overhead.
