When Fairness Naturally Emerges From Deep Ensembling
Ensembling independent deep neural networks (DNNs) is a simple and effective way to improve top-line metrics and to outperform larger single models. In this work, we go beyond top-line metrics and instead explore the impact of ensembling on subgroup performances. Surprisingly, even with a simple homogenous ensemble -- all the individual models share the same training set, architecture, and design choices -- we find compelling and powerful gains in worst-k and minority group performance, i.e. fairness naturally emerges from ensembling. We show that the gains in performance from ensembling for the minority group continue for far longer than for the majority group as more models are added. Our work establishes that simple DNN ensembles can be a powerful tool for alleviating disparate impact from DNN classifiers, thus curbing algorithmic harm. We also explore why this is the case. We find that even in homogeneous ensembles, varying the sources of stochasticity through parameter initialization, mini-batch sampling, and the data-augmentation realizations, results in different fairness outcomes.
Privileged Bases in the Transformer Residual Stream
Our mathematical theories of the Transformer architecture suggest that individual coordinates in the residual stream should have no special significance (that is, the basis directions should be in some sense "arbitrary" and no more likely to encode information than random directions). Recent work has shown that this observation is false in practice. We investigate this phenomenon and provisionally conclude that the per-dimension normalizers in the Adam optimizer are to blame for the effect.
We explore two other obvious sources of basis dependency in a Transformer: Layer normalization, and finite-precision floating-point calculations. We confidently rule these out as being the source of the observed basis-alignment.
LLaMA-Adapter: Efficient Fine-tuning of Language Models with Zero-init Attention
We present LLaMA-Adapter, a lightweight adaption method to efficiently fine-tune LLaMA into an instruction-following model. Using 52K self-instruct demonstrations, LLaMA-Adapter only introduces 1.2M learnable parameters upon the frozen LLaMA 7B model, and costs less than one hour for fine-tuning on 8 A100 GPUs. Specifically, we adopt a set of learnable adaption prompts, and prepend them to the input text tokens at higher transformer layers. Then, a zero-init attention mechanism with zero gating is proposed, which adaptively injects the new instructional cues into LLaMA, while effectively preserves its pre-trained knowledge. With efficient training, LLaMA-Adapter generates high-quality responses, comparable to Alpaca with fully fine-tuned 7B parameters. Furthermore, our approach can be simply extended to multi-modal input, e.g., images, for image-conditioned LLaMA, which achieves superior reasoning capacity on ScienceQA.
good update thank you!
