Srinivasan Keshav posted a link to this excellent deepdive by Prasad Raje of Udemy into the advances that DeepSeek R1 has made from a perspective of the core technology.

Affordable digitisation of insect collections using photogrammetry This is an idea proposed in 2025 as a Cambridge Computer Science Part III or MPhil project, and is currently being worked on by Beatrice Spence, Arissa-Elena Rotunjanu and Anna Yiu. It is co-supervised with Tiffany Ki and Edgar Turner.

Using computational SSDs for vector databases This is an idea proposed in 2025 as a Cambridge Computer Science Part III or MPhil project, and is available for being worked on. It may be co-supervised with Sadiq Jaffer. Large pre-trained models can be used to embed media/documents into concise vector representations with the property that vectors that are "close" to each other are semantically related.
