10 systems

Therml

Founder.

Silicon for inference. The chip settles an energy-based network into its answer, in place of clocking through the matrix multiplications.

Contour map of an energy landscape with noisy trajectories settling into its minima — Langevin trajectories settling on an energy landscape

Louie.ai

Co-founder, Chief Architect. With Graphistry.

An investigation agent: it queries the databases, walks the graph and writes up what it found. It is the first generative agent to complete Splunk's Boss of the SOC, a competition set for human security operations analysts, answering all of the 200-series questions and half of the 300-series in minutes. In use at the United States Army and Fortune 500 companies.

IO.net

Intelligence layer

The intelligence layer over a distributed compute network, and the chat interface in front of it.

A network of nodes with one path highlighted from corner to corner — Shortest path across a random geometric graph, 190 nodes

Beats Music

Lead Data Scientist

Four recommendation systems, of which the one behind Just for You learned its priors from about a million playlists by scoring how each song handed off to the next, and The Sentence built a playlist from a mood, a place and the company. Apple bought Beats in 2014 and the service became Apple Music.

Song-to-song transitions in a simulated playlist corpus

Tehama

Chief AI Architect

Dr Manhattan, the audit and compliance engine inside Tehama's virtual desktops: several asynchronous pipelines that model what a user is doing, in what context, and whether policy allows it.

Rows of short bars across a twenty-four hour axis, with a few out-of-hours bars marked in amber — Simulated desktop sessions over a day, 44 desks, out-of-pattern activity marked

Pythian

Chief Scientist

The machine learning practice, built from nothing, and systems for more than thirty clients, generally several models feeding one another. Tehama was spun out of the company.

Six small plots: a classifier boundary, a forecast, clusters, a covariance matrix, outliers and a regression band — Classifier, forecast, clustering, topic covariance, outliers, Gaussian process

Stay Open

Co-founder, 2019

Property technology. The architect tool generates floor layouts and prices each one against its pro forma, which is to say its revenue, cost and payroll.

Layout tool

Grid of generated floor plans in four stages: raw, outline, layout and final — Generated layouts: raw, outline, layout, final

Mediajel

Chief Scientist, Machine Learning Architect

Real-time advertising, with Bayesian bidding across mobile, web and physical location.

Five probability curves narrowing around a dashed line — Beta posterior on a click rate after 20 to 5,120 impressions

Quid

Lead Prototype Developer

Natural language inference in parallel over large external corpora, returned as a network one could query.

A network of coloured clusters joined by sparse links — Stochastic block model, six communities, force-directed

Idle Games

Senior Data Scientist

Behavioural models of players in social games. Acquired by GSN.

Grid of dots sized by the probability of moving between player states — Transition matrix of a simulated player-state Markov chain

Advisor to 8tracks, Arternal, Rhumbix and Zeta Global. Clients have included Sonos, Pandora, Uber, Unilever, ARM, In-Q-Tel, Ford Direct, HotelTonight and RetailMeNot.
