Answer When Needed, Forget When Not: Language Models Pretend to Forget via In-Context Knowledge Unlearning

ACL 2025finding

As large language models (LLMs) are applied across diverse domains, the ability to selectively unlearn specific information is becoming increasingly essential. For instance, LLMs are expected to selectively provide confidential information to authorized internal users, such as employees or trusted p…

Inconsistent Tokenizations Cause Language Models to be Perplexed by Japanese Grammar

ACL 2025short

Typical methods for evaluating the performance of language models evaluate their ability to answer questions accurately. These evaluation metrics are acceptable for determining the extent to which language models can understand and reason about text in a general sense, but fail to capture nuanced ca…

Language Models Do Hard Arithmetic Tasks Easily and Hardly Do Easy Arithmetic Tasks

ACL 2024short

The ability (and inability) of large language models (LLMs) to perform arithmetic tasks has been the subject of much theoretical and practical debate. We show that LLMs are frequently able to correctly and confidently predict the first digit of n-digit by m-digit multiplication tasks without using c…

Which Programming Language and What Features at Pre-training Stage Affect Downstream Logical Inference Performance?

EMNLP 2024main

Recent large language models (LLMs) have demonstrated remarkable generalization abilities in mathematics and logical reasoning tasks.Prior research indicates that LLMs pre-trained with programming language data exhibit high mathematical and reasoning abilities; however, this causal relationship has…

Multitask Soft Option Learning

UAI 2020poster

We present Multitask Soft Option Learning (MSOL), a hierarchical multitask framework based on Planning as Inference. MSOL extends the concept of options, using separate variational posteriors for each task, regularized by a shared prior. This “soft” version of options avoids several instabilities du…
