Target-Language Generation in Multilingual Models: Activation Steering and Optimal Control

James A. Michaelov, Carmen Amo Alonso, Tyler A. Chang +1

Ensuring that multilingual language models generate coherent text in a specific target language is a major issue in multilingual language modeling. We develop an optimal control me…

Bigram Subnetworks: Mapping to Next Tokens in Transformer Language Models

Tyler A. Chang, Benjamin K. Bergen

In Transformer language models, activation vectors transform from current token embeddings to next token predictions as they pass through the model. To isolate a minimal form of th…

On the Acquisition of Shared Grammatical Representations in Bilingual Language Models

Catherine Arnett, Tyler A. Chang, James A. Michaelov +1

Crosslingual transfer is crucial to contemporary language models' multilingual capabilities, but how it occurs is not well understood. We ask what happens to a monolingual language…

Goldfish: Monolingual Language Models for 350 Languages

Tyler A. Chang, Catherine Arnett, Zhuowen Tu +1

For many low-resource languages, the only available language models are large multilingual models trained on many languages simultaneously. Despite state-of-the-art performance on…

Different Tokenization Schemes Lead to Comparable Performance in Spanish Number Agreement

Catherine Arnett, Pamela D. Rivière, Tyler A. Chang +1

The relationship between language model tokenization and performance is an open area of research. Here, we investigate how different tokenization schemes impact number agreement in…

A Bit of a Problem: Measurement Disparities in Dataset Sizes Across Languages

Catherine Arnett, Tyler A. Chang, Benjamin K. Bergen

How should text dataset sizes be compared across languages? Even for content-matched (parallel) corpora, UTF-8 encoded text can require a dramatically different number of bytes for…

When Is Multilinguality a Curse? Language Modeling for 250 High- and Low-Resource Languages

Tyler A. Chang, Catherine Arnett, Zhuowen Tu +1

Multilingual language models are widely used to extend NLP systems to low-resource languages. However, concrete evidence for the effects of multilinguality on language modeling per…

Structural Priming Demonstrates Abstract Grammatical Representations in Multilingual Language Models

James A. Michaelov, Catherine Arnett, Tyler A. Chang +1

Abstract grammatical knowledge - of parts of speech and grammatical patterns - is key to the capacity for linguistic generalization in humans. But how abstract is grammatical knowl…

Crosslingual Structural Priming and the Pre-Training Dynamics of Bilingual Language Models

Catherine Arnett, Tyler A. Chang, James A. Michaelov +1

Do multilingual language models share abstract grammatical representations across languages, and if so, when do these develop? Following Sinclair et al. (2022), we use structural p…

Characterizing Learning Curves During Language Model Pre-Training: Learning, Forgetting, and Stability

Tyler A. Chang, Zhuowen Tu, Benjamin K. Bergen

How do language models learn to make predictions during pre-training? To study this, we extract learning curves from five autoregressive English language model pre-training runs, f…

Characterizing and Measuring Linguistic Dataset Drift

Tyler A. Chang, Kishaloy Halder, Neha Anna John +4

NLP models often degrade in performance when real world data distributions differ markedly from training data. However, existing dataset drift metrics in NLP have generally not con…

Language Model Behavior: A Comprehensive Survey

Tyler A. Chang, Benjamin K. Bergen

Transformer language models have received widespread public attention, yet their generated text is often surprising even to NLP researchers. In this survey, we discuss over 250 rec…

Do Large Language Models know what humans know?

Sean Trott, Cameron Jones, Tyler Chang +2

Humans can attribute beliefs to others. However, it is unknown to what extent this ability results from an innate biological endowment or from experience accrued through child deve…

The Geometry of Multilingual Language Model Representations

Tyler A. Chang, Zhuowen Tu, Benjamin K. Bergen

We assess how multilingual language models maintain a shared multilingual representation space while still encoding language-sensitive information in each language. Using XLM-R as…

Word Acquisition in Neural Language Models

Tyler A. Chang, Benjamin K. Bergen

We investigate how neural language models acquire individual words during training, extracting learning curves and ages of acquisition for over 600 words on the MacArthur-Bates Com…

Convolutions and Self-Attention: Re-interpreting Relative Positions in Pre-trained Language Models

Tyler A. Chang, Yifan Xu, Weijian Xu +1

In this paper, we detail the relationship between convolutions and self-attention in natural language tasks. We show that relative position embeddings in self-attention layers are…

Co-Scale Conv-Attentional Image Transformers

Weijian Xu, Yifan Xu, Tyler Chang +1

In this paper, we present Co-scale conv-attentional image Transformers (CoaT), a Transformer-based image classifier equipped with co-scale and conv-attentional mechanisms. First, t…

Encodings of Source Syntax: Similarities in NMT Representations Across Target Languages

Tyler A. Chang, Anna N. Rafferty

We train neural machine translation (NMT) models from English to six target languages, using NMT encoder representations to predict ancestor constituent labels of source language w…
