Multimodal Learning and Its Challenges - Multimodal learning is driving breakthroughs in fields like medical imaging and human-computer interaction by integrating various data types such as images, text, and tables [2]. - A significant issue in real-world applications is "missing modality," where certain data inputs are incomplete, leading to potential loss of critical information [3][7]. The Discarding-Imputation Dilemma - Existing methods for handling missing modalities fall into two categories: recovery-free methods that ignore missing data and recovery-based methods that attempt to reconstruct it, both of which have inherent drawbacks [11][12]. - The article highlights the "discarding-imputation dilemma," where discarding can lead to loss of important information, while imputation may introduce noise [3][12]. DyMo Framework - DyMo is designed to address the aforementioned dilemma by dynamically identifying and integrating reliable recovery modalities during the inference phase [15][39]. - The framework establishes a connection between information gain and task loss, utilizing a reward function to guide the modality selection process [19][21]. Experimental Results - DyMo has been tested on multiple datasets, including PolyMNIST, MST, and CelebA, demonstrating significant performance improvements in scenarios with missing modalities [4][30]. - For instance, in the PolyMNIST dataset, DyMo achieved a classification accuracy increase of 1.61% under missing modality conditions [12][31]. Conclusion and Future Directions - DyMo offers a novel perspective on multimodal learning, shifting the focus from merely recovering all modalities to determining which recovery modalities are trustworthy [39]. - Future research directions include extending dynamic selection to the training phase and exploring applications beyond classification tasks [41].

Core Viewpoint - The article discusses the introduction of Emu3, a multimodal large model developed by Beijing Academy of Artificial Intelligence, which aims to unify the learning of text, images, and videos through next-token prediction, potentially transforming the AI landscape [2][3]. Multimodal Learning - Multimodal learning refers to the ability of AI to process various types of information simultaneously, akin to human sensory perception. Achieving a unified algorithm for learning and generating content from multiple modalities has been a long-standing challenge in the AI field [6]. Emu3's Mechanism - Emu3 employs a simple yet effective approach by converting all modal data into discrete tokens and using a Transformer model to predict the next token, which is a key factor in the success of GPT series language models [6][7]. Training Process - The training of Emu3 consists of three stages: 1. Pre-training with large-scale multimodal data, balancing the loss weights of text and visual tokens to prevent dominance of visual tokens [10]. 2. Post-training for quality fine-tuning on generation tasks, incorporating human preference optimization [10]. 3. Inference supporting classifier-free guidance for low-latency and high-throughput generation [11]. Performance Comparison - Emu3 has demonstrated performance that matches or exceeds specialized models across various tasks: - In image generation, it achieved a human preference score of 70.0, surpassing Stable Diffusion v1.5 (59.3) and SDXL (66.9) [13]. - In video generation, it scored 81.0 in VBench evaluation, comparable to mainstream diffusion models [13]. - In visual language understanding, it averaged 62.1 across 12 benchmark tests, rivaling models like LLaVA-1.6 [13]. - In robotic operations, it achieved a success rate of 87.0% in a simulated environment [13]. Significance of the Research - The significance of Emu3 lies not only in its performance improvements but also in its simplification of paradigms. It demonstrates that next-token prediction can serve as a core paradigm for multimodal models, paving the way for the development of more powerful "world models" that integrate perception, language, and action [15][17]. Future Developments - Following Emu3, the research team has introduced Emu3.5, which enhances the model's capabilities through large-scale long-sequence video training, improving its ability to model physical world dynamics and observing trends in multimodal capabilities as the model and data scale increase [15].

Core Insights - The article discusses the development of a new dual-system visual-language-action model named Fast-in-Slow (FiS-VLA) that integrates high-frequency response and complex reasoning in robotic control [4][29]. Group 1: Research Background and Challenges - The goal of robotic operating systems is to generate precise control signals based on sensor inputs and language instructions in complex environments. However, large-scale visual-language models (VLMs) have limitations due to their large parameters and slow inference speed, which restrict their practical use in high-frequency control tasks [7]. - The research draws inspiration from Kahneman's "dual-system theory," where System 1 represents fast, intuitive decision-making, and System 2 represents slower, deeper reasoning. Previous methods attempted to create a dual-system structure but lacked efficient collaboration between the two systems [8][9]. Group 2: FiS-VLA Architecture and Design - FiS-VLA proposes an innovative structure that directly reconstructs the last few layers of the VLM into a System 1 execution module, embedding it within System 2 to form a unified model for efficient reasoning and control. System 2 processes 2D images and language instructions at a low frequency, while System 1 responds to real-time sensory inputs at a high frequency [11][13]. - The architecture includes a visual encoder, a lightweight 3D tokenizer, a large language model (LLaMA2-7B), and several MLP modules for modality fusion and diffusion modeling. This design allows System 1 to inherit pre-trained knowledge and achieve high-frequency execution [13]. Group 3: Dual-System Collaboration - FiS-VLA consists of a slow System 2 and a fast System 1, where System 2 processes task-related visual observations and language instructions, converting them into high-dimensional features. System 1 focuses on real-time action generation, receiving current sensory inputs and outputting actions while utilizing periodic updates from System 2 [14][15]. - The model employs asynchronous sampling to control the operating frequency of the two systems, ensuring time consistency in action generation [14]. Group 4: Performance Evaluation - In simulation tests, FiS-VLA achieved an average success rate of 69% in RLBench tasks, outperforming other models like CogACT (61%) and π0 (55%). The control frequency reached 21.9Hz, more than double that of CogACT [17]. - In real robot platforms (Agilex and AlphaBot), FiS-VLA demonstrated average success rates of 68% and 74% across eight tasks, significantly surpassing the π0 baseline [19]. - The model exhibited robust performance in generalization tests, showing a smaller accuracy decline compared to π0 when faced with unseen objects, complex backgrounds, and lighting changes [21]. Group 5: Ablation Studies and Future Directions - Ablation studies indicated that the optimal performance of System 1 occurs when sharing two Transformer layers, and the best collaboration frequency ratio between Systems 1 and 2 is 1:4. The theoretical control frequency can reach up to 117.7Hz when predicting eight actions at once [23]. - The article concludes that FiS-VLA innovatively merges reasoning and control within a unified VLM, achieving high-frequency, high-precision, and strong generalization capabilities in robotic manipulation. Future enhancements may include dynamic adjustments to shared structures and collaborative frequency strategies to improve adaptability and robustness in real-world tasks [29].
