- Title: STLM Engineering Report: Dropout
- Authors: Dylan Hillier, Leon Guertler, Bobby Cheng, Cheston Tan,
- Abstract summary: We find that dropout remains effective in the overfitting scenario, and that it may have some relevance for improving the fit of models even in the case of excess data.
In the process we find that the existing explanation for the mechanism behind this performance gain is not applicable in the case of language modelling.

- Abstract: In this work we explore the relevance of dropout for modern language models, particularly in the context of models on the scale of <100M parameters. We explore it's relevance firstly in the regime of improving the sample efficiency of models given small, high quality datasets, and secondly in the regime of improving the quality of its fit on larger datasets where models may underfit. We find that concordant with conventional wisdom, dropout remains effective in the overfitting scenario, and that furthermore it may have some relevance for improving the fit of models even in the case of excess data, as suggested by previous research. In the process we find that the existing explanation for the mechanism behind this performance gain is not applicable in the case of language modelling.

We introduce model kinship, the degree of similarity or relatedness between Large Language Models.
We find that there is a certain relationship between model kinship and the performance gains after model merging.
We propose a new model merging strategy: Top-k Greedy Merging with Model Kinship, which can yield better performance on benchmark datasets.

Low-rank approximation techniques have become the de facto standard for fine-tuning Large Language Models.
This paper investigates the effectiveness of these methods in capturing the shift of fine-tuning datasets from the initial pre-trained data distribution.
We show that low-rank fine-tuning inadvertently preserves undesirable biases and toxic behaviors.

Approach [25.927323251675386]
We leverage the meta-features associated with each entity as a source of worldly knowledge and employ entity representations from the models.
We propose using the consistency between these representations and the meta-features as a metric for evaluating pre-trained models.
Our method's effectiveness is demonstrated across various domains, including models with relational datasets, large language models and image models.

We propose QualEval, which augments quantitative scalar metrics with automated qualitative evaluation as a vehicle for model improvement.
QualEval uses a powerful LLM reasoner and our novel flexible linear programming solver to generate human-readable insights.
We demonstrate that leveraging its insights, for example, improves the absolute performance of the Llama 2 model by up to 15% points relative.

Fine-tuning pre-trained language models has become the prevalent paradigm for building downstream NLP models.
This creates a barrier to fusing knowledge across individual models to yield a better single model.
We propose a dataless knowledge fusion method that merges models in their parameter space.

We analyze a set of existing bias features and demonstrate there is no single model that works best for all the cases.
By choosing an appropriate bias model, we can obtain a better robustness result than baselines with a more sophisticated model design.

Models that are more accurate on the out-of-distribution data relative to this baseline exhibit "effective robustness"
We find that models pre-trained on larger datasets exhibit effective robustness during training that vanishes at convergence.
We discuss several strategies for scaling effective robustness to the high-accuracy regime to improve the out-of-distribution accuracy of state-of-the-art models.
