  • In recent months, the world of artificial intelligence and deep learning has witnessed a surge in innovation, particularly in the realm of image generation. The advent of diffusion models has marked a significant turning point in this field, with applications ranging from artistic expression to medical imaging analysis. As researchers delved deeper into the intricacies of these models, they began to unravel the underlying mathematics that governs their behavior.

    To gain a profound understanding of the mechanisms at play, several individuals embarked on an exhaustive examination of diffusion networks. This endeavor involved scrutinizing the mathematical equations that underpin these models, as well as exploring alternative perspectives offered by prominent researchers such as Lilian Weng and Yang Song. The latter's work, in particular, shed light on the score-based generation models that have gained significant attention in recent times.

    However, upon delving into the existing literature, it became apparent that many resources failed to provide a comprehensive account of the mathematical derivations necessary to grasp the underlying principles of diffusion networks. This lacuna in understanding led some researchers to undertake their own investigations, aiming to bridge the gap between theoretical foundations and practical applications.

    As part of this pursuit, a presentation was delivered internally on November 26, 2024, which served as a catalyst for further exploration. The content of this presentation drew heavily from Lilian Weng's blog, Yang Song's intuitive review, and other sources cited in the slides. Furthermore, the author undertook additional derivations to enhance their comprehension, with a view to developing a reference document that would serve as a valuable resource for deep learning courses.

    The VITALab, a research initiative affiliated with Sherbrooke University, also played a significant role in this journey. The laboratory's website and GitHub repository provided access to valuable resources, including videos, images, and theoretical materials that aided in the author's quest for knowledge.

    Through their exhaustive efforts, researchers have made substantial progress in deciphering the workings of diffusion networks. As this field continues to evolve, it is essential to develop a thorough understanding of its fundamentals. The presentation mentioned above serves as a testament to the dedication and perseverance required to achieve such breakthroughs.

    In conclusion, the recent advancements in diffusion models represent a pivotal moment in the history of artificial intelligence. By grasping the underlying mathematics and theoretical underpinnings of these models, researchers can unlock new possibilities for image generation, medical imaging analysis, and other applications.
