Large language models (LLM) are mainly designed for text -based tasks, which limits their ability to interpret and generate multimodal content, such as images, videos and audio. Conventionally, multimodal operations are specific models of trained tasks in large amounts of data labeled, which makes them hungry for resources and rigid. Zero shooting methods are also restricted to pre -recess with matimodal data sets paired, which limits its flexibility to new tasks. The challenge is to make the LLM perform multimodal reasoning and generation without specific training of tasks, cured data or adaptation of the model. Overcoming this challenge would significantly improve the applicability of the LLM to the processing and generation of multimodal content dynamically in multiple domains.
Conventional multimodal systems are based on models such as clip for image text alignment or dissemination models for media generation. Even so, these methods are restricted to wide training in cured data. The zero shooting subtitles models such as Zerocap and Meacap try to overcome this, but are still restricted to fixed architectures and gradient -based optimization, restricting their capacity for generalization in different modalities. These methods have three limitations: they are restricted to extensive labeled data, cannot be generalized beyond training distribution and are based on gradient -based methods that restrict their flexibility to new tasks. Without exceeding these limitations, the multimodal ai is restricted to tasks and fixed data sets, restricting its potential for new applications.
Meta researchers propose MILS (multimodal LLM Solution), a test time optimization frame that improves LLMs with multimodal reasoning capabilities without requiring additional training. Instead of adjusting the LLM or re -training in multimodal data, Mils uses an iterative optimization cycle with a generator and scorer. The generator, a LLM, produces candidate solutions for multimodal tasks such as image subtitles, video descriptions or stylized image indications, while the scorer, a previously trained multimodal model, classifies the solutions generated by relevance, coherence and alignment with data of data from data from entrance. Alternating between the two, mils repeatedly refine their results with real -time feedback, continuously improving performance. This allows zero shooting generalization in several modalities, including text, images, videos and audio, which makes it an extremely versatile solution for multimodal ai applications.
MILS is implemented as an optimization method without gradient, which uses previously trained models without adjusting its parameters. The frame has been used in a variety of multimodal tasks. For image subtitles, Mils uses Llama 3.1 8b as generator -based models and clip as the scorer to find iteratively optimal subtitles until the most precise and descriptive legend is generated. The same iterative process for video frameworks is used, with Viclip using for the evaluation and to subtitulate the audio, MILS extends the process to the audio data with the use of Imagebind as the scorer, which allows LLM to generate descriptions of Natural language sounds. For image generation, MILS optimizes the indications of image generation by optimizing textual descriptions before sending them to diffusion -based models, generating higher high quality images. The framework even extends to style transfer, where it generates optimized editing indications that direct -style transfer models to generate more visually consistent transformations. In addition, it proposes intermodal arithmetic, which combines heterogeneous modalities, such as an audio legend and a description of the image, in a multimodal representation. Using previously trained models as punctuation functions, MILS can avoid explicit multimodal training while an agnostic of tasks.
MILS achieves a robust zero shooting performance in a variety of multimodal tasks and surpasses previous work in subtitles and generation. For the subtitles of the images, it is more semantically precise than the previous zero shooting models and generates more natural and informative subtitles. For video and audio subtitles, it exceeds the models trained in large -scale data sets even with zero specific task training. For the generation of image in the image, Mils improves the quality and loyalty of the image, and the human evaluators prefer their images synthesized in an overwhelming majority of cases. Mils is also effective for style transfer, learning optimal indications for better visual transformation. Finally, Mils achieves new intermodal arithmetic characteristics, allowing the combined information of the modalities to generate coherent results. These findings demonstrate the flexibility and efficiency of MILS, so it is an alternative that breaks the paradigm to multimodal systems based on carefully selected training data.
MILS offers a new paradigm for multimodal ai in its ability to allow the LLM to generate and process the text, image, video and audio content without fine training and adjustment. Its iterative optimization mechanism of test time allows emerging zero shooting generalization, overcoming the previous zero shooting methods but keeping simple. Using previously trained LLMS and multimodal models in adaptive feedback, Mils creates a new state of the art for multimodal ai, which allows more adaptive and scalable systems that can dynamically process the tasks of reasoning and multimodal generation.
