Claudiu Popescu PH.D
A software engineer and researcher with 10 years of work experience. Last 8 years I worked mainly in the area of machine learning.
The focus of my research in recent years was mostly on designing and analyzing machine learning algorithms.
Especially interested in algorithms and methods that have a solid theoretical foundation, while also solving real-world problems.
As a software engineer, I worked on a wide variety of projects. They range from standard machine learning projects consisting of gathering and cleaning the data, and training a model using some library or framework, to very complex projects involving the design and implementation of new algorithms for the specific tasks.
