[1] LLMs Surpass Human Experts in Predicting Neuroscience Results

Scientific breakthroughs often depend on integrating extensive research, a challenge that may exceed human capabilities. LLMs provide a promising solution, as they can process and synthesize vast amounts of scientific studies to predict new findings more accurately than human experts. This study introduces BrainBench, a benchmark designed for assessing the ability of LLMs to predict neuroscience outcomes. Results indicate that LLMs, particularly a version called BrainGPT which was specifically enhanced with neuroscience literature, outperform human experts in forecasting experimental results. Additionally, LLMs accuracy increases with their confidence in predictions, suggesting a collaborative future between humans and LLMs in scientific discovery.

[2] Adding NVMe SSDs to Enable and Accelerate 100B Model Fine-tuning on a Single GPU

Recent advances in LLMs are constrained by the limitations of GPU memory, which struggles to handle the models extensive parameters during optimization. This poses a significant challenge, especially for academic researchers with limited budgets, unable to afford multiple high-end GPUs for model training. Addressing this, the paper introduces Fuyou, a cost-effective training framework designed for fine-tuning vast models, up to 100 billion parameters, on single, low-end GPUs in commodity servers with restricted CPU memory. By incorporating SSD-CPU communication into the optimization process, Fuyou maximizes GPU utilization through systematic computation and data swapping. This approach enables the fine-tuning of models significantly larger than previously possible on consumer hardware, with Fuyou successfully fine-tuning a 175 billion parameter GPT-3 model on an RTX 4090 GPU, outperforming the state-of-the-art ZeRO-Infinity in terms of efficiency and achievable model size.

[3] MoAI: Mixture of All Intelligence for Large Language and Vision Models

The development of large language and vision models (LLVMs) has been propelled by the instruction tuning of LLMs, focusing on integrating vast vision language (VL) data or creating specific instruction tuning datasets. Current LLVMs, however, often overlook the rich, real-world scene understanding from specialized computer vision (CV) models in tasks like segmentation, detection, scene graph generation (SGG), and optical character recognition (OCR). To address this, a new LLVM named Mixture of All Intelligence (MoAI) is introduced, which enhances VL tasks by utilizing auxiliary visual information from external CV models. MoAI integrates this information through two innovative modules: MoAI-Compressor, which aligns and condenses the external CV models' outputs, and MoAI-Mixer, which merges visual, auxiliary, and language features using a Mixture of Experts approach. This strategy enables MoAI to significantly surpass both open-source and proprietary LLVMs in various zero-shot VL tasks, including those requiring intricate scene understanding, without increasing model size or needing additional visual instruction datasets.

[4] Gemma: Open Models Based on Gemini Research and Technology

This work introduces Gemma, a series of lightweight, state-of-the-art models derived from the technology behind the Gemini models, showcasing superior performance in language understanding, reasoning, and safety across academic benchmarks. With two versions featuring 2 billion and 7 billion parameters, Gemma offers both pretrained and fine-tuned checkpoints. It excels over comparable open models in 11 of 18 text-based tasks. The paper also delves into safety and responsibility in model use, providing an extensive evaluation and detailing the development process. Emphasizing the importance of responsible LLM releases, the authors advocate for enhancing the safety of cutting-edge models and fostering innovation in the field of large language models. [Link ]

[5] Gemini 1.5: Unlocking Multimodal Understanding Across Millions of Tokens of Context

The latest addition to the Gemini family, Gemini 1.5 Pro, is a compute-efficient multimodal mixture-of-experts model, excelling in processing and reasoning over extensive contexts, including long documents and hours of multimedia content. It achieves nearly perfect recall in long-context retrieval across various modalities and sets new benchmarks in long-document QA, long-video QA, and long-context ASR, equaling or outperforming its predecessor, Gemini 1.0 Ultra, across a wide range of tests. Remarkably, Gemini 1.5 Pro demonstrates significant advances in processing up to 10 million tokens, significantly surpassing previous models like Claude 2.1 and GPT-4 Turbo. Among its breakthroughs, it showcases an ability to learn new languages, such as translating English to Kalamang—a language with less than 200 speakers—after exposure to a grammar manual, showcasing the potential of large language models in language preservation and learning.

[6] Chronos: Learning the Language of Time Series

Chronos introduces a novel approach to time series forecasting by leveraging pretrained probabilistic models through a simple yet effective framework. By tokenizing time series data using scaling and quantization into a fixed vocabulary, Chronos adapts transformer-based language model architectures, specifically the T5 family with models ranging from 20M to 710M parameters, to time series forecasting. The training utilizes a mix of publicly available datasets and a custom synthetic dataset created via Gaussian processes for enhanced generalization. In an extensive evaluation across 42 diverse datasets, Chronos not only significantly surpasses other forecasting methods on familiar datasets but also demonstrates comparable or occasionally superior zero-shot forecasting accuracy on previously unseen datasets. These findings highlight Chronos's ability to improve forecasting across various domains, suggesting that pretrained models could greatly streamline forecasting processes. [Link ]

[7] ELLA: Equip Diffusion Models with LLM for Enhanced Semantic Alignment

Diffusion models excel in text-to-image generation but often rely on CLIP for text encoding, limiting their understanding of complex prompts. This paper introduces the Efficient Large Language Model Adapter (ELLA), enhancing text-to-image models' prompt comprehension without additional training of U-Net or LLMs. ELLA employs a novel Timestep-Aware Semantic Connector (TSC) to dynamically integrate semantic conditions from LLMs, tailored for each denoising stage, enabling more accurate interpretation of detailed and lengthy prompts. Designed for easy integration with existing models and tools, ELLA significantly improves adherence to intricate prompts. The effectiveness of ELLA is validated through the Dense Prompt Graph Benchmark (DPG-Bench), a comprehensive test with 1K dense prompts, showing ELLA's superior performance in rendering images with complex object arrangements, attributes, and relationships compared to current leading methods.

This study explores the development of high-performing Multimodal Large Language Models (MLLMs), focusing on the critical aspects of architecture components and data selection. Through detailed examinations, key insights were gained, highlighting the importance of a strategic blend of image-caption, interleaved image-text, and text-only data for top-tier few-shot learning outcomes across various benchmarks. It was found that the choice of image encoder, image resolution, and token count significantly influences model performance, while the design of the vision-language connector plays a lesser role. Leveraging these findings, the MM1 model family was created, encompassing up to 30 billion parameters, including both dense models and mixture-of-experts (MoE) variants. These models set new standards in pre-training effectiveness and demonstrate competitive results in multimodal benchmarks after supervised fine-tuning. Notably, the extensive pre-training endows MM1 models with superior in-context learning and multi-image reasoning capabilities, facilitating advanced few-shot chain-of-thought prompting. [Link ]
