Introduction

Nikolaos Chatzipanagiotis is a prominent inventor based in Seattle, WA (US). He has made significant contributions to the field of machine learning and causal analysis, holding a total of 5 patents. His work focuses on developing advanced techniques that enhance the understanding of event causality and its impact on outcomes.

Latest Patents

One of his latest patents is titled "Machine learning analysis of incremental event causality towards a target outcome." This patent relates to machine learning techniques that identify the incremental impact of different past events on the likelihood of a target outcome occurring. The technology utilizes a recurrent neural network to analyze two representations of an event sequence—one where a specific event occurs and another where it does not. The incremental impact of that event is determined by calculating the difference in probabilities of the target outcome after these two sequences.

Another notable patent is the "Causal analysis system." This invention includes methods and apparatus for identifying features that may significantly impact key application metrics. These methods rely on observational data to estimate the importance of application features and employ causal inference tools such as Double Machine Learning (double ML) or Recurrent Neural Networks (RNN). This technology allows developers to estimate the effectiveness of features without conducting online experiments, thereby optimizing key metrics for mobile applications, web applications, and other web-based programs.
