Exploratory Model Analysis Using Data-Driven Neuron Representations

no code implementations EMNLP (BlackboxNLP) 2021 Daisuke Oba, Naoki Yoshinaga, Masashi Toyoda

Probing classifiers have been extensively used to inspect whether a model component captures specific linguistic phenomena.

Tracing the Roots of Facts in Multilingual Language Models: Independent, Shared, and Transferred Knowledge

1 code implementation8 Mar 2024 Xin Zhao, Naoki Yoshinaga, Daisuke Oba

Acquiring factual knowledge for language models (LMs) in low-resource languages poses a serious challenge, thus resorting to cross-lingual transfer in multilingual LMs (ML-LMs).

In-Contextual Gender Bias Suppression for Large Language Models

1 code implementation13 Sep 2023 Daisuke Oba, Masahiro Kaneko, Danushka Bollegala

We show that, using CrowsPairs dataset, our textual preambles covering counterfactual statements can suppress gender biases in English LLMs such as LLaMA2.

Dynamic Data Augmentation with Gating Networks for Time Series Recognition

1 code implementation5 Nov 2021 Daisuke Oba, Shinnosuke Matsuo, Brian Kenji Iwana

We propose a neural network that dynamically selects the best combination of data augmentation methods using a mutually beneficial gating network and a feature consistency loss.

Modeling Personal Biases in Language Use by Inducing Personalized Word Embeddings

no code implementations NAACL 2019 Daisuke Oba, Naoki Yoshinaga, Shoetsu Sato, Satoshi Akasaki, Masashi Toyoda

In this study, we propose a method of modeling such personal biases in word meanings (hereafter, semantic variations) with personalized word embeddings obtained by solving a task on subjective text while regarding words used by different individuals as different words.
