In the landmark paper "Outrageously Large Neural Networks: The Sparsely-Gated Mixture-of-Experts Layer," a revolutionary approach to neural network scalability is unveiled, fundamentally challenging conventional methods in neural network design. This study, spearheaded by Noam Shazeer and his team, introduces a novel strategy to expand the capacity of neural networks significantly, without necessitating a proportional increase in computational resources. At the core of this innovation is the development of the Sparsely-Gated Mixture-of-Experts (MoE) layer, a sophisticated assembly of numerous feed-forward sub-networks known as 'experts', governed by a trainable gating network. …
In the field of machine learning, the Deep Mixture of Experts (DMoE) model, as discussed in "Learning Factored Representations in a Deep Mixture of Experts," offers a novel perspective. To fully appreciate its impact, we must first explore its predecessors: the standard Mixture of Experts (MoE), the Product of Experts (PoE), and the Hierarchical Mixture of Experts. …
We've taken on the exciting challenge of implementing the cutting-edge strategies presented in "ZEPHYR: Direct Distillation of LM Alignment". This paper's approach is not just theoretical—it's a blueprint for a significant leap in language model training. By adopting ZEPHYR's distilled direct preference optimization (dDPO), we've embarked on a code journey that brings these innovations from concept to reality. …
In today's rapidly growing world of conversational AI, developers often seek ways to leverage multiple models seamlessly to diversify outputs and enhance user experience. One such scenario involves using different Local Language Models (LLMs) to serve different purposes or to offer a variety of responses. In this article, we'll explore a method to set up and switch between multiple local LLMs, particularly Zephyr and Mistral 7B, using the Chainlit and Langchain libraries. …
Model fine-tuning and quantization play pivotal roles in creating efficient and robust machine learning solutions. This blog post explores the fine-tuning process of the Zephyr 7B GPT-Q model using 4-bit quantization to boost its performance for custom data inference tasks. …
