Types of Data

Multimodal AI systems engage with diverse data types that include, but are not limited to, text, images, audio, and video. Each modality offers unique and complementary insights, which when combined, provide a more holistic interpretation than unimodal data.

For instance, in an image captioning task, visual data (the image itself) and textual data (the caption) are both vital.

Data Fusion Techniques

Data fusion a critical process in multimodal AI, involves strategically combining data from different modalities to improve decision-making or prediction accuracy.

Techniques include early fusion, which merges raw data before any processing, and late fusion, where data is combined after some level of individual processing.

A more complex approach, intermediate fusion, may align the data at various levels, maintaining the distinctiveness of each modality while still enabling combined analysis.

Unified Representation of Data

Creating a unified representation of data involves transforming diverse datasets into a format that can be seamlessly processed by AI systems.
