#110 Unpacking Bayesian Methods in AI with Sam Duffield
Learning Bayesian Statistics
Journey from Bayesian Inference to State-Space Models and Gaussian Processes
The chapter explores the speaker's evolution from being introduced to Bayesian inference to focusing on state-space models and Gaussian processes for data analysis. It highlights their interest in applying these techniques to time series models and developing innovative solutions in the field of statistics and AI.
