Ricky Ma

Cognitive data scientist + ML research engineer.
BSc. Cognitive Systems - Computational Intelligence and Design.

Hello! I am currently a visiting student researcher in the Causality in Cognition Lab at Stanford University, researching computational models of counterfactual inference with Tobias Gerstenberg. We are studying how humans combine observational and interventional data from populations to make decisions themselves, and how to model these cognitive processes through causal networks and simulations.

I have also joined Lautonomy as CTO to develop a platform to supercharge human rights and environmental law protection, removing the complexity that systemically blocks fair and equitable access to law. Currently, we are building a legal knowledge graph using international laws and treaties in partnership with Freedom From Torture and The AIRE Centre to improve redress and access to legal representation for torture survivors and asylum seekers.

I completed my BSc. at UBC studying Cognitive Systems with a focus in Computational Intelligence and Design, directed by the Computer Science Department. I’ve spent time at the WiNMoS Lab with Yanjie Dong doing research in decentralized reinforcement learning. I’ve also worked with Matthew Cooke at Snyder Lab on scientific software development and data analysis for behavioural neuroscience.

Previously, I developed a novel framework for unsupervised anomalous object detection at RecyclEye. At Algomo, I created an interactive model-understanding and evaluation platform for chatbot data and feedback, and invented a brand-new method for named entity recognition using OpenAI’s GPT-3.

Research interests:

  • Generative deep learning models
  • Self-supervised and semi-supervised learning
  • Causal reasoning and its effects on interpretability and generalization
  • Causal learning and inference in neural networks and time-series models
  • ML and AI for social good

Jul 16, 2021 Excited to announce that I will be officially joining Lautonomy as CTO. I hope to use my knowledge and experience to contribute to Lautonomy’s goal of promoting equal access to legal services for all.
May 12, 2021 I am joining the Causality in Cognition Lab at Stanford University as a visiting student researcher! I will be studying computational models of counterfactual inference.
Apr 26, 2021 I’m graduating soon! :sparkles: :fire:
