Multi-modal learning is an educational strategy that involves multiple ways of conveying information to learners. It refers to teaching the learners using different sensory modalities like visual, auditory, and kinesthetic or tactile. In the field of artificial intelligence (AI) and machine learning (ML), multi-modal learning involves the design of models that can process and relate information from multiple types of data such as audio, video, and text.
How Multimodal Learning works
In AI and ML, multi-modal learning models often involve the combination of different types of data. For instance, an AI model might be trained to identify objects in videos by processing both visual data (the images in the video) and auditory data (the accompanying soundtrack). This is usually achieved by designing a model with multiple branches, each responsible for processing a different type of data, and then combining their outputs to make a final decision or prediction.
The process involves training the model on correlational relationships between the multiple modalities. This helps the model to generate a comprehensive representation of the data. For instance, in a multi-modal learning model trained to understand speech from videos, the visual data might provide information about the speaker's lip movements, while the audio data provides the actual sound. Together, they enable the model to better understand and transcribe the speech.
In essence, the fundamental principle behind multi-modal learning is that the more perspectives (or modalities) a model has on an input, the better it can understand, learn, and predict that input.
