AI research explores structural generalization in RL and NLP · 2 sources tracked

Two new research papers explore different facets of generalization in AI models. The first paper, focusing on offline reinforcement learning, argues that the structure of pessimism in datasets is more critical for generalization than the sheer volume of data. It suggests that data augmentation, when applied through a consistency loss, can improve generalization by enforcing symmetric value functions. The second paper investigates structural generalization in natural language processing, proposing a new parser that encodes directionality. This parser, using a BERT-base encoder, outperforms previous state-of-the-art models on specific directional tasks, indicating that incorporating directional information is key for certain types of linguistic generalization.

    Generalization in offline RL: The structure is more important than the amount of pessimism

    arXiv:2607.02288v1 Announce Type: cross Abstract: While pessimism counteracts overestimation bias in offline reinforcement learning (RL), being overly conservative has been associated with hindering certain forms of generalization. However, in this paper we demonstrate that being…

    On the Role of Directionality in Structural Generalization

    arXiv:2607.02307v1 Announce Type: new Abstract: Several SLOG test categories explicitly involve directional distinctions (modifier position shifts, argument extraction positions), yet AM-Parser, the previous SOTA, uses an AM algebra whose operations do not encode direction. We re…
