Multimodality and Data Fusion Techniques in Deep Learning 

Petar Velev, Senior Software Engineer at Bosch Engineering Center Sofia
In this lecture, I will introduce the concept of multimodal deep learning and highlight the critical role of data fusion techniques. I’ll begin by explaining the principle of multimodality and how it aligns with the inherently multimodal nature of human cognition.
Through real-world examples, such as networks that merge audio and video, audio and accelerometer, or audio and text, I’ll illustrate how multimodal learning is implemented in practice.
A key part of the discussion will be devoted to data fusion techniques - early, late, and hybrid fusion. I’ll present their applications and discuss their respective advantages and potential limitations.
To conclude, I’ll provide a brief overview of the future of multimodal deep learning, touching on potential developments and challenges. The aim of this lecture is to offer a succinct yet comprehensive understanding of multimodal deep learning, demonstrating its transformative potential in the field of AI.
