- Title: Methods for Estimating and Improving Robustness of Language Models
- Authors: Michal \v{S}tef\'anik
- Abstract summary: Large language models (LLMs) suffer notorious flaws related to their preference for simple, surface-level textual relations over full semantic complexity.
This proposal investigates a common denominator of this problem in their weak ability to generalise outside of the training domain.
We find that incorporating some of these measures in the training objectives leads to enhanced distributional robustness of neural models.

- Abstract: Despite their outstanding performance, large language models (LLMs) suffer
notorious flaws related to their preference for simple, surface-level textual
relations over full semantic complexity of the problem. This proposal
investigates a common denominator of this problem in their weak ability to
generalise outside of the training domain. We survey diverse research
directions providing estimations of model generalisation ability and find that
incorporating some of these measures in the training objectives leads to
enhanced distributional robustness of neural models. Based on these findings,
we present future research directions towards enhancing the robustness of LLMs.

We introduce an adapted two-stage Learning-to-Defer mechanism that enhances decision-making by enabling selective deference to human experts or larger models without retraining language models in the context of question-answering.
Our results demonstrate that deferring a minimal number of queries allows the smaller model to achieve performance comparable to their larger counterparts while preserving computing efficiency.

Training large language models (LLMs) to serve as effective assistants for humans requires careful consideration.
A promising approach is reinforcement learning from human feedback (RLHF), which leverages human feedback to update the model in accordance with human preferences.
In this paper, we analyze RLHF through the lens of reinforcement learning principles to develop an understanding of its fundamentals.

Systematic Literature Review [10.325003320290547]
This systematic literature review comprehensively examines the application of Large Language Models (LLMs) in forecasting and anomaly detection.
LLMs have demonstrated significant potential in parsing and analyzing extensive datasets to identify patterns, predict future events, and detect anomalous behavior across various domains.
This review identifies several critical challenges that impede their broader adoption and effectiveness, including the reliance on vast historical datasets, issues with generalizability across different contexts, and the phenomenon of model hallucinations.
