At the end, a reflection on how these advances may impact your projects or companies in the future will be presented!

[1] We-Math: Does Your Large Multimodal Model Achieve Human-like Mathematical Reasoning?

Visual mathematical reasoning is crucial in the field of Large Multimodal Models (LMMs). Existing benchmarks, like MathVista and MathVerse, emphasize result-oriented performance but overlook principles in knowledge acquisition and generalization. Inspired by human-like reasoning, WE-MATH is introduced as the first benchmark to explore problem-solving principles beyond performance. It includes 6.5K visual math problems, covering 67 knowledge concepts and five layers of granularity. Problems are decomposed into sub-problems and assessed using a four-dimensional metric: Insufficient Knowledge (IK), Inadequate Generalization (IG), Complete Mastery (CM), and Rote Memorization (RM). Evaluations reveal a negative correlation between solving steps and performance, with GPT-4o advancing in knowledge generalization while others lean towards rote memorization. WE-MATH aims to advance visual mathematical reasoning in LMMs. [Link ]

[2] Summary of a Haystack: A Challenge to Long-Context LLMs and RAG Systems

Evaluating the output quality of LLMs and RAG systems on long-context tasks is challenging. This study introduces the "Summary of a Haystack" (SummHay) task to address this, requiring systems to process synthesized Haystacks of documents, identify relevant insights, and accurately cite sources. The SummHay task provides a reproducible automatic evaluation scoring summaries on Coverage and Citation. Evaluations in two domains (conversation, news) show that SummHay remains a challenge, with current systems lagging behind human performance. Systems like GPT-4o and Claude 3 Opus score below 20% without a retriever. SummHay also helps study enterprise RAG systems and position bias in long-context models. [Link ]

[3] ROS-LLM: A ROS framework for Embodied AI with task feedback and Structured Reasoning

Introducing a framework for intuitive robot programming by non-experts, leveraging natural language prompts and contextual information from the Robot Operating System (ROS). This system integrates LLMs, enabling users to articulate task requirements through a chat interface. Key features include: ROS integration with an AI agent connected to various LLMs, automatic extraction of behavior from LLM outputs and execution of ROS actions/services, support for sequence, behavior tree, and state machine modes, imitation learning for adding new robot actions, and LLM reflection via human and environment feedback. Extensive experiments demonstrate robustness, scalability, and versatility in diverse scenarios. The code is open-source to support adoption and result reproduction. [Link ]

[4] OpenVid-1M: A Large-Scale High-Quality Dataset for Text-to-video Generation

Text-to-video (T2V) generation has gained attention with the multi-modality model Sora but still faces challenges: 1) Lack of a precise, high-quality open-source dataset, as existing datasets like WebVid-10M and Panda-70M are either low quality or too large. 2) Inadequate utilization of textual information, as current methods rely on simple cross-attention modules. To address these, we introduce OpenVid-1M, a high-quality dataset with over 1 million text-video pairs and expressive captions. Additionally, OpenVidHD-0.4M, with 433K 1080p videos, advances high-definition video generation. We also propose the Multi-modal Video Diffusion Transformer (MVDiT), which effectively mines structure from visual tokens and semantics from text tokens. Extensive experiments show the superiority of OpenVid-1M and MVDiT's effectiveness. [Link ]

[5] InternLM-XComposer-2.5: A Versatile Large Vision Language Model Supporting Long-Contextual Input and Output

InternLM-XComposer-2.5 (IXC-2.5) is a versatile large-vision language model supporting long-context input and output, excelling in text-image comprehension and composition. With a 7B LLM backend, it achieves GPT-4V level capabilities. Trained with 24K interleaved image-text contexts and extendable to 96K via RoPE extrapolation, IXC-2.5 excels in tasks requiring extensive contexts. Upgrades from version 2.0 include Ultra-High Resolution Understanding, Fine-Grained Video Understanding, and Multi-Turn Multi-Image Dialogue. It also extends to crafting webpages and composing high-quality text-image articles using extra LoRA parameters. Evaluated on 28 benchmarks, IXC-2.5 outperforms state-of-the-art models on 16 benchmarks and competes closely with GPT-4V and Gemini Pro on key tasks. [Link ]

[6] Scaling Synthetic Data Creation with 1,000,000,000 Personas

A novel persona-driven data synthesis methodology leverages various perspectives within an LLM to create diverse synthetic data. Persona Hub, a collection of 1 billion personas curated from web data, acts as carriers of world knowledge, tapping into almost every perspective within the LLM. These personas facilitate the large-scale creation of diverse synthetic data for various scenarios. Use cases include synthesizing high-quality mathematical and logical reasoning problems, user prompts, knowledge-rich texts, game NPCs, and tools. This versatile, scalable, and flexible approach can drive a paradigm shift in synthetic data creation, significantly impacting LLM research and development. [Link ]

[7] HuatuoGPT-Vision, Towards Injecting Medical Visual Knowledge into Multimodal LLMs at Scale

The rapid development of multimodal large language models (MLLMs), like GPT-4V, has advanced the field, but challenges remain in medical multimodal capabilities due to limited high-quality data. Addressing this, the PubMedVision dataset was created by refining medical image-text pairs from PubMed and using MLLMs to denoise and reformat the data, resulting in 1.3 million medical VQA samples. Validation shows PubMedVision significantly enhances MLLMs' medical capabilities, with improvements in benchmarks and superior data quality validated by experts. Using PubMedVision, the 34B medical MLLM HuatuoGPT-Vision was trained, outperforming other open-source MLLMs in medical multimodal scenarios. [Link ]

[8] TabReD: A Benchmark of Tabular Machine Learning in-the-Wild

Benchmarks reflecting real-world scenarios are crucial for adopting new research in tabular ML. This study identifies two underrepresented characteristics in current academic datasets: the temporal nature of tabular data and the complex feature engineering pipelines in industry. Existing datasets often lack timestamp metadata and vary significantly in feature composition. To address these gaps, TabReD, a collection of eight industry-grade tabular datasets, is introduced, covering diverse domains like finance and food delivery. Evaluations using TabReD reveal that time-based data splits yield different method rankings than random splits, with MLP-like architectures and GBDT performing best, while advanced DL models still need to demonstrate effectiveness.
