This newsletter brings AI research news that is much more technical than most resources but still digestible and applicable

Hey Folks!

This newsletter will discuss some cool AI research papers, AI tools, and AI Startups. Happy learning!

👉 What is Trending in AI/ML Research?

In an unprecedented move fostering accountability in the rapidly evolving Generative AI (GenAI) space, Vectara has released an open-source Hallucination Evaluation Model, marking a significant step towards standardizing the measurement of factual accuracy in Large Language Models (LLMs). This initiative establishes a commercial and open-source resource for gauging the degree of ‘hallucination’ or the divergence from verifiable facts by LLMs, coupled with a dynamic and publicly available leaderboard. The release aims to bolster transparency and provide an objective method to quantify the risks of hallucinations in leading GenAI tools, an essential measure for promoting responsible AI, mitigating misinformation, and underpinning effective regulation. The Hallucination Evaluation Model is set to be a pivotal tool in assessing the extent to which LLMs remain grounded in facts when generating content based on provided reference material.

How can diffusion models be enhanced for greater flexibility while maintaining their core advantages? The paper proposes "DiffEnc", a novel framework that adapts diffusion models by introducing a variable mean function in the diffusion process, resulting in an optimized diffusion loss. This approach achieves state-of-the-art performance on CIFAR-10. Additionally, it explores varying the noise variance ratio between the reverse encoder and generative process. The findings include that for finite-depth hierarchies, a weighted diffusion loss can be optimized alongside the noise schedule for improved inference, while for infinite-depth hierarchies, this ratio must be fixed to ensure a well-defined evidence lower bound (ELBO).

In an industry where innovation is both rapid and revolutionary, OpenAI has yet again pushed the boundaries of what artificial intelligence can achieve with the introduction of GPT-4 Turbo, a more potent and customizable iteration of its widely-acclaimed language model.

During the company’s annual DevDay conference, OpenAI CEO Sam Altman showcased the new model’s capabilities, which are not just a step, but a leap forward from its predecessor. The GPT-4 Turbo boasts enhanced precision and a more nuanced understanding of complex instructions, positioning it as a formidable tool in the AI landscape. The enhanced capabilities of GPT-4 Turbo are evident in its sophisticated text generation, which can now effortlessly handle a wider array of nuanced requests. The model can generate summaries, compose emails, and even draft articles with a level of polish that blurs the line between human and machine-generated content.

How can we make Large Language Models (LLMs) more computationally efficient? This paper presents "LoRAShear," a method for reducing LLMs' size by structurally pruning the models while preserving knowledge. It identifies minimally removable structures in the LoRA modules through dependency graphs, and then prunes LoRAShear adaptors progressively, ensuring knowledge is retained. To compensate for any knowledge lost during pruning, the method applies dynamic fine-tuning with data adaptors, effectively maintaining performance levels close to unpruned models. Results show a 20% reduction in model size with only a 1% drop in performance, a significant improvement over existing techniques.

A team of researchers from Rice University and Amazon Web Services have developed a distributed training system called GEMINI, which aims to improve failure recovery in the training of large machine learning models. The system deals with the challenges associated with using CPU memory for checkpoints, which ensures higher availability and minimizes interference with training traffic. GEMINI has shown significant improvement over existing solutions, making it a promising advancement in large-scale deep-learning model training.
