Hidden Markov Models
A Hidden Markov Model describes a system that moves through hidden states you cannot see directly, emitting observable outputs along the way.
TechnicalGaussian Processes
A Gaussian Process is a flexible, nonparametric way to model functions that comes with built-in uncertainty estimates.
IndustriesAI in Surgery and Surgical Robotics
AI is moving surgical robots from teleoperated tools that simply mirror a surgeon's hands toward systems that can perceive tissue, guide instruments…
IndustriesAI in Ophthalmology
Ophthalmology is one of AI's biggest medical success stories because the eye is image-rich and easy to photograph.
IndustriesAI in Dermatology
Skin is the body's largest, most visible organ, so dermatology is a natural fit for image-based AI.
