Generalization Analysis on Learning with a Concurrent Verifier

no code implementations11 Oct 2022 Masaaki Nishino, Kengo Nakamura, Norihito Yasuda

In practical situations, it is natural to expect the input-output pairs of a machine learning model to satisfy some requirements.

Differentiable Inductive Logic Programming for Structured Examples

1 code implementation2 Mar 2021 Hikaru Shindo, Masaaki Nishino, Akihiro Yamamoto

Our framework can be scaled to deal with complex programs that consist of several clauses with function symbols.

Bilingual Text Extraction as Reading Comprehension

no code implementations29 Apr 2020 Katsuki Chousa, Masaaki Nagata, Masaaki Nishino

We also conduct a sentence alignment experiment using En-Ja newspaper articles and find that the proposed method using multilingual BERT achieves significantly better accuracy than a baseline method using a bilingual dictionary and dynamic programming.

A Supervised Word Alignment Method based on Cross-Language Span Prediction using Multilingual BERT

no code implementations EMNLP 2020 Masaaki Nagata, Chousa Katsuki, Masaaki Nishino

For example, we achieved an F1 score of 86. 7 for the Chinese-English data, which is 13. 3 points higher than the previous state-of-the-art supervised methods.

Variable Shift SDD: A More Succinct Sentential Decision Diagram

no code implementations6 Apr 2020 Kengo Nakamura, Shuhei Denzumi, Masaaki Nishino

We show that VS-SDDs are never larger than SDDs and there are cases in which the size of a VS-SDD is exponentially smaller than that of an SDD.

Recovery command generation towards automatic recovery in ICT systems by Seq2Seq learning

no code implementations24 Mar 2020 Hiroki Ikeuchi, Akio Watanabe, Tsutomu Hirao, Makoto Morishita, Masaaki Nishino, Yoichi Matsuo, Keishiro Watanabe

With the increase in scale and complexity of ICT systems, their operation increasingly requires automatic recovery from failures.

Metric Learning for Ordered Labeled Trees with pq-grams

1 code implementation9 Mar 2020 Hikaru Shindo, Masaaki Nishino, Yasuaki Kobayashi, Akihiro Yamamoto

In order to perform metric learning based on pq-grams, we propose a new differentiable parameterized distance, weighted pq-gram distance.

Provable Fast Greedy Compressive Summarization with Any Monotone Submodular Function

no code implementations NAACL 2018 Shinsaku Sakaue, Tsutomu Hirao, Masaaki Nishino, Masaaki Nagata

This approach is known to have three advantages: its applicability to many useful submodular objective functions, the efficiency of the greedy algorithm, and the provable performance guarantee.

Oracle Summaries of Compressive Summarization

no code implementations ACL 2017 Tsutomu Hirao, Masaaki Nishino, Masaaki Nagata

This paper derives an Integer Linear Programming (ILP) formulation to obtain an oracle summary of the compressive summarization paradigm in terms of ROUGE.

Enumeration of Extractive Oracle Summaries

no code implementations EACL 2017 Tsutomu Hirao, Masaaki Nishino, Jun Suzuki, Masaaki Nagata

To analyze the limitations and the future directions of the extractive summarization paradigm, this paper proposes an Integer Linear Programming (ILP) formulation to obtain extractive oracle summaries in terms of ROUGE-N. We also propose an algorithm that enumerates all of the oracle summaries for a set of reference summaries to exploit F-measures that evaluate which system summaries contain how many sentences that are extracted as an oracle summary.
