Multimodal machine learning refers to machine learning models that can process and relate information from multiple modalities or sources of input data. Some key things to know about multimodal machine learning:
-
Modalities refer to different modes or formats of data, such as text, images, audio, video, sensor data, etc. Multimodal systems combine data from two or more of these modalities.
-
Multimodal machine learning aims to build models that can process multiple data modalities together to perform a task. This enables the models to learn correlations across modalities.
-
Key benefits include gaining a more comprehensive understanding of the data, being able to handle real-world data that naturally combines multiple modalities, reducing ambiguity, and improving model accuracy and robustness.
-
Typical tasks where multimodal learning is applied include multimodal speech recognition, image/video captioning, multimodal emotion/sentiment analysis, multimodal biometric identification, multimodal document analysis, etc.
-
Technical approaches to multimodal learning include joint embedding spaces, co-training models on separate modalities, using one modality to guide another, multimodal fusion methods, and training end-to-end multimodal neural networks.
Multimodal machine learning aims to build models that can process and relate multiple data types like text, audio, images together, just as humans perceive the world through multiple senses. The key benefit is being able to learn deeper connections across different modalities.
