In conversation with AI: building better language models
Our new paper, In conversation with AI: aligning language models with human values, explores a different approach, asking what successful communication between humans and an artificial conversational agent might look like and what values should guide conversation in these contexts.
DIY-IPS: Towards an Off-the-Shelf Accurate Indoor Positioning System
We present DIY-IPS - Do It Yourself - Indoor Positioning System, anopen-source real-time indoor positioning mobile application. DIY-IPS detectsusers’ indoor position by employing dual-band RSSI fingerprinting of availableWiFi access points. The app can be used, without additional infrastructural…

Uni-Mol: A Universal 3D Molecular Representation Learning Framework
Molecular representation learning (MRL) has gained tremendous attention due to its critical role in learning from limited supervised data for applications like drug design. In most MRL methods, molecules are treated as 1D sequential tokens or 2D topology graphs, limiting their ability to incorporate…

Collaborative machine learning that preserves privacy
MIT researchers developed a system that streamlines the process of federated learning, a technique where users collaborate to train a machine-learning model in a way that safeguards each user’s data. The system reduces communication costs of federated learning and boosts accuracy of a machine-learni…

The distance backbone of directed networks
In weighted graphs the shortest path between two nodes is often reachedthrough an indirect path, out of all possible connections, leading tostructural redundancies which play key roles in the dynamics and evolution ofcomplex networks. We have previously developed a parameter-free,algebraically-p…
