Scholar-generated biography
Efthymios Costa is a Postdoctoral Research Associate at Imperial College London, specializing in Statistics, Machine Learning, and Computational statistics. His research focuses on handling mixed-type data through unsupervised learning techniques, with an emphasis on clustering and outlier detection. Costa has developed novel methods for partitioning mixed-type data and introduced frameworks for quantifying nominal outlyingness. His work includes the creation of the 'IBclust' package, which implements the Deterministic Information Bottleneck algorithm for clustering. Costa's research bridges theoretical and applied aspects of statistical modeling, particularly in the context of complex data structures.
