Key Recent Developments
DeepMind makes breakthrough to give AI mathematical capabilities never seen before
What: DeepMind collaborated with mathematicians to apply AI to discovering new insights in areas of mathematics. The approached used supervised learning, training algorithms with labeled data to predict outcomes. The research proposes a new approach to a longstanding conjecture in representation theory, and a previously unknown algebraic quantity in the theory of knots. The AI detects patterns in mathematics at a vast scale and in a huge dimensional space, augmenting the insights of mathematicians and proving proof of new theorems.
Key Takeaways: Besides augmenting the work of mathematicians, DeepMind also notes that knot theory has connections with quantum field theory and non-Euclidian geometry. In particular, how the relationships of algebra, geometry and quantum theory in the study of knots is an open question.

Google and Cambridge propose a universal transformer for image, video, and audio classification
What: The neural network transformer architecture was first introduced in 2017 and had a profound impact in natural language processing, and the classification of images, video and audio. Until now, a separate model would be trained for each of these tasks. Researchers have now demonstrated a single transformer architecture co-trained on image, audio and video that is parameter-efficient and that generalises across multiple domains.
Key Takeaway: Transformer models have grown to huge sizes with an ever increasing financial cost and environmental impact. The demonstrated model achieves state of the art performance while being more compact. It does not increase training cost compared to training separate models and may reduce it. This is an example of research effort seeking to make existing models more efficient rather than creating ever-larger models.
AI-designed "living robots" observed self-replicating
What: Xenobots are combinations of frog stem cells designed by AI into 3D structures and referred to as “living robots”. About the size of a grain of sand, they are constructed in the real world by humans. They can move around Petri dishes and push microscopic objects without external input. The xenobots have now been observed self-replicating in a manner previously unknown in nature. This reproductive process was further enhanced by tweaks to the AI design.
Key Takeaways: The authors speculate that this form for self-replication may have been essential in the origin of life. Furthermore, the authors note that the AI design methods can be applied to exaggerate existing behaviours and “in future, possibly guide them toward more useful forms”.
