Private AI Collaborative Research Institute


the development of fundamental technologies that are instrumental in strengthening the security, Privacy and trustworthiness of decentralized artificial intelligence (AI)

Our Research Focus

The Private AI Collaborative Research Institute will focus its efforts on overcoming five main obstacles of the current centralized approach:

Training data is decentralized in isolated silos and often inaccessible.

Most data stored at the edge is privacy-sensitive and cannot be moved to the cloud.

Today’s solutions are insecure and require a single trusted data center.

Centralized training can be easily attacked by modifying data anywhere between collection and cloud. There is no framework for decentralized secure training among potentially untrusting participants.

Centralized models become obsolete quickly.

Infrequent batch cycles of collection, training, and deployment lead to outdated models, making continuous and differential retraining not possible.

Centralized compute resources are costly and throttled by communication and latency.

It requires vast data storage and compute as well as dedicated accelerators to make training viable.

Federated Machine Learning (FL) is limited.

While FL can access data at the edge, it cannot reliably guarantee privacy and security.
