LOA: Logical Optimal Actions for Text-based Interaction Games

1 code implementation ACL 2021 Daiki Kimura, Subhajit Chaudhury, Masaki Ono, Michiaki Tatsubori, Don Joven Agravante, Asim Munawar, Akifumi Wachi, Ryosuke Kohita, Alexander Gray

We present Logical Optimal Actions (LOA), an action decision architecture of reinforcement learning applications with a neuro-symbolic framework which is a combination of neural network and symbolic knowledge acquisition approach for natural language interaction games.

Reinforcement Learning with External Knowledge by using Logical Neural Networks

no code implementations3 Mar 2021 Daiki Kimura, Subhajit Chaudhury, Akifumi Wachi, Ryosuke Kohita, Asim Munawar, Michiaki Tatsubori, Alexander Gray

Specifically, we propose an integrated method that enables model-free reinforcement learning from external knowledge sources in an LNNs-based logical constrained framework such as action shielding and guide.

Polar Embedding

no code implementations CoNLL (EMNLP) 2021 Ran Iwamoto, Ryosuke Kohita, Akifumi Wachi

Particularly, the latest approaches such as hyperbolic embeddings showed significant performance by representing essential meanings in a hierarchy (generality and similarity of objects) with spatial properties (distance from the origin and difference of angles).

Structural Supervision Improves Few-Shot Learning and Syntactic Generalization in Neural Language Models

no code implementations EMNLP 2020 Ethan Wilcox, Peng Qian, Richard Futrell, Ryosuke Kohita, Roger Levy, Miguel Ballesteros

Humans can learn structural properties about a word from minimal experience, and deploy their learned syntactic representations uniformly in different grammatical contexts.

Interactive Construction of User-Centric Dictionary for Text Analytics

no code implementations ACL 2020 Ryosuke Kohita, Issei Yoshida, Hiroshi Kanayama, Tetsuya Nasukawa

We propose a methodology to construct a term dictionary for text analytics through an interactive process between a human and a machine, which helps the creation of flexible dictionaries with precise granularity required in typical text analysis.

Image Position Prediction in Multimodal Documents

no code implementations LREC 2020 Masayasu Muraoka, Ryosuke Kohita, Etsuko Ishii

Datasets for these tasks contain a large number of pairs of an image and the corresponding sentence as an instance.

Dynamic Feature Selection with Attention in Incremental Parsing

no code implementations COLING 2018 Ryosuke Kohita, Hiroshi Noji, Yuji Matsumoto

One main challenge for incremental transition-based parsers, when future inputs are invisible, is to extract good features from a limited local context.

A neural parser as a direct classifier for head-final languages

no code implementations WS 2018 Hiroshi Kanayama, Masayasu Muraoka, Ryosuke Kohita

This paper demonstrates a neural parser implementation suitable for consistently head-final languages such as Japanese.

Effective Online Reordering with Arc-Eager Transitions

no code implementations WS 2017 Ryosuke Kohita, Hiroshi Noji, Yuji Matsumoto

We present a new transition system with word reordering for unrestricted non-projective dependency parsing.

Multilingual Back-and-Forth Conversion between Content and Function Head for Easy Dependency Parsing

1 code implementation EACL 2017 Ryosuke Kohita, Hiroshi Noji, Yuji Matsumoto

Universal Dependencies (UD) is becoming a standard annotation scheme cross-linguistically, but it is argued that this scheme centering on content words is harder to parse than the conventional one centering on function words.
