Alex Alves Freitas

Also known as A Freitas, A. A. Freitas, A. Freitas, A.A. Freitas, Alex A Freitas, Alex A. Freitas, Alex Freitas

Alex Alves Freitas is a computer scientist whose machine-learning work connects data mining with biological questions. He earned a computer science PhD at the University of Essex in 1997 and published a 2002 book on evolutionary algorithms for knowledge discovery. Ant-Miner used ant-colony optimization to find classification rules, and his later research applied machine learning to bioinformatics and ageing. He coauthored a 2025 paper introducing Scikit-Longitudinal, a Python library for longitudinal classification. At the University of Kent, he is Professor of Computational Intelligence and Director of Research and Innovation.

Timeline

  1. 1997

    A PhD in machine learning

    At the University of Essex, he earns a computer science PhD in 1997 while researching machine learning, also called data mining.

  2. 2002

    An evolutionary data-mining book

    His 2002 book, Data Mining and Knowledge Discovery with Evolutionary Algorithms, brings evolutionary algorithms together with data mining.

  3. 2002

    The Ant-Miner algorithm

    The 2002 Ant-Miner paper introduces an ant-colony-based algorithm for extracting classification rules from data; Freitas coauthors it with Rafael Parpinelli and Heitor Lopes.

  4. 2005

    Machine learning for life sciences

    From about 2005, his research focuses on machine-learning methods for bioinformatics and life-sciences data, including protein-function prediction and analysis of ageing-related genes and proteins.

  5. 2006

    Unordered Ant-Miner rules

    With James Smaldon, he introduces Unordered Rule Set Ant-Miner in 2006; it produces classification rules that can be interpreted independently.

  6. 2011

    An ageing research MPhil

    In 2011, he earns a research-oriented MPhil in Biological Sciences at the University of Liverpool, studying the biology of ageing with machine learning and bioinformatics.

  7. 2025

    Scikit-Longitudinal library

    In 2025, he coauthors a paper introducing Scikit-Longitudinal, a machine-learning library for longitudinal classification in Python.

  8. As of October 2026

    Professor at the University of Kent

    As of October 2026, he is Professor of Computational Intelligence and Director of Research and Innovation at the University of Kent, where he teaches Data Mining and Knowledge Discovery and Natural Computation.

  1. More people shaping AI studied at Massachusetts Institute of Technology than at any other institutionIncludes University of Kent. We estimate where the people shaping AI studied and where their careers led. Massachusetts Institute of Technology leads with 467 former students, including 291 recorded doctorates.
  2. The company share of AI researchers’ top papers was 31% in 2020–2024 and 8% in 1970–1974Includes University of Kent. We estimate where the people shaping AI worked when their most-cited papers appeared: the company share was 31% in 2020–2024 and 8% in 1970–1974, and Google led all organizations in 2020–2024.
  3. The Massachusetts Institute of Technology trained or employed 44 of the 187 AI major-prize winners, more than any other universityIncludes University of Kent. The Massachusetts Institute of Technology trained or employed 44 of the 187 AI major-prize winners, more than any other university. We compare doctorate and 5+ year employment links, career timing and current workplaces for 187 major-prize and 1,111 best-paper winners.
  4. Google had the most people shaping AI every year from 2014 to 2025Our estimates of which organizations employed the most people shaping AI each year from 1955 to 2025, tracing the shift from university labs to companies.
