Alibaba Researchers Introduce R1-Omni: An Application of Reinforcement Learning with Verifiable Reward (RLVR) to an Omni-Multimodal Large Language Model

Learn about the emotion of the video includes many precise challenges. Models that depend exclusively on visual or audio signals often lack the complex interaction between these methods, which leads to a bad interpretation of emotional content. The main difficulty in the plural is reliable between the visible sermon – such as facial expressions or body language – with auditory signals such as tone or intonation. Many current systems also lack the ability to explain their decision -making process, making it difficult to understand how to discover specific feelings. Moreover, these models can sometimes generate thinking that does not directly reflect input data, or may fail to use the fully important sound details. These issues become more clear when the models face unfamiliar scenarios, emphasizing the need for a more powerful and interpretative approach to learn about multiple feelings.

Presenting R1 -omni by researchers alibaba

In their last work, researchers at Alibaba R1-UMNI, which is a reinforcement learning application with a verified bonus (RLVR) to a large multilateral language model specifically designed to learn about emotion. R1-omni depends on the applicable Humanomni frame and apps RLVR to set the form to deal with both video and sound data. The method begins with a cold starting stage, where the model is pre -trained using a built -in data collection of Multimedia (EMER) thinking and handcrafted data. This initial training for the model helps to learn basic thinking skills before it is improved with RLVR. By combining the bases-based reward mechanism in the training process, the R1-omni is improved not only to predict the emotion but also to generate clear and interpretable explanations that describe how visual and auditory information interacts.

Technical ideas and the benefits of approach

At the core of the R1-omni design, there is a reinforcement learning integration with verified bonuses (RLVR) and improving the group’s relative policy (GRPO). RLVR replaces the need for self -reactions with a verified bonus function that evaluates the output of the form against objective standards. The reward system is clear and direct: If the emotional prediction of the model corresponds to the basic truth, it receives a reward 1; Otherwise, it receives 0. In addition, the coordination reward guarantees that the result is committed to a specific structure, as the thinking process is clearly separated from the final prediction by the designated signs.

GRPO also ends the training process by comparing groups of candidates’ responses, allowing the model to determine and benefit those who have more coherent and interpretative thinking. This mechanism helps reduce the occurrence of uninterrupted or unspecified thinking while improving the comprehensive quality of predictions. Together, these technical strategies contribute to promoting thinking, better understanding of multimedia inputs, and improving performance, especially when the model is tested on the data he had not seen before.

Experimental results and major notes

The study provides a comprehensive set of experiences that compare R1-omni to many basic models, including the original Humanomni-0.b and trained models with SFT refinement (SFT) on EMER and MAFW-DFEW data sets. On the DFEW data collection, R1-omni achieves an unwanted recall (UAR) by 65.83 % and the average suggestion (war) of 56.27 %. These grades significantly higher than those obtained with other methods. Likewise, in the MAFW data collection, R1-UMNI explains improving performance, highlighting its ability to accurately classify feelings in different categories.

There is an additional power for R1-UMNI is its ability to generate detailed and coherent thinking processes. Examples of the perception presented in the study show that, compared to other models, R1-omni provides explanations better reflecting how visual and sound signals contribute to prediction. The model also shows strong generalization capabilities when evaluated on the Ravdess Data set – a group that includes professional representatives and unified discourse. This indicates that the model is able to adapt to different types of input data while maintaining a fixed level of performance.

Final ideas and future trends

In short, R1-omni represents a deliberate approach to challenge the identification of multimedia feelings. By taking advantage of the reinforcement learning with verified bonuses, the model is improved not only to predict feelings more precisely but also to express thinking behind its decisions. This approach helps in dealing with some long -term problems in this field, such as integrating multimedia data and explaining the outputs of the model.

Despite its progress, R1-omni still faces challenges. For example, improving the recognition of translation and reducing uninterrupted thinking areas for further exploration. Future research may focus on enhancing the basic model, improving the integration of sound signals, and deepening the capabilities of the model to better determine the accuracy of human emotional understanding.

In general, the R1-omni provides a promising framework that balances technical rigor with the need for interpretation, which contributes to valuable visions to developing systems to identify multiple emotional emotions more transparent and effective.
