How do large language models (LLMs) develop and evolve over the course of training?
How do these patterns change as models scale? To answer these questions, we introduce …

Deep reinforcement learning (RL) algorithms are predominantly evaluated by comparing
their relative performance on a large suite of tasks. Most published results on deep RL …

Universality is a key hypothesis in mechanistic interpretability–that different models learn
similar features and circuits when trained on similar tasks. In this work, we study the …

Pretraining is the preliminary and fundamental step in developing capable language models
(LM). Despite this, pretraining data design is critically under-documented and often guided …

Recent trends in language modeling have focused on increasing performance through
scaling, and have resulted in an environment where training language models is out of …

We present a conceptual framework, datamodeling, for analyzing the behavior of a model
class in terms of the training data. For any fixed" target" example $ x $, training set $ S $, and …

Understanding Transformer-based models has attracted significant attention, as they lie at
the heart of recent technological advances across machine learning. While most …

Standard fine-tuning of large pre-trained language models (PLMs) for downstream tasks
requires updating hundreds of millions to billions of parameters, and storing a large copy of …

Similarity measures are a vital tool for understanding how language models represent and
process language. Standard representational similarity measures such as cosine similarity …

Customer satisfaction is one of the most important measures in the hospitality industry.
Therefore, several psychological and cognitive theories have been utilized to provide …
