Multimodal in AI refers to models that can process and integrate multiple types of data, such as text, images, and audio. This allows the models to capture a richer understanding of the data and perform more complex tasks.
Multimodal models work by processing each type of data separately, using appropriate feature extraction techniques, and then combining the features into a unified representation. This can be done using various methods, such as concatenation, fusion, or attention mechanisms. The combined representation can then be used to make predictions or perform other tasks.
Multimodal models can handle a wider range of tasks and data types than unimodal models, making them more versatile and powerful.
Multimodal models are used in many areas of AI, including computer vision, natural language processing, and speech recognition. For example, they can be used to build systems that can understand and generate content across different media, such as generating a textual description of an image, or determining the sentiment of a piece of text based on both its content and tone of voice.
