Welcome to Aptikal!

The APTIKAL team (Algorithms, Principles and TheorIes for collaborative Knowledge Acquisition and Learning) is the Machine Learning group of LIG, created in January 2011. We work on machine learning and information modelling for complex data.

Within this broad area of research, we have in particular developed strong interests and expertise in four major themes:

• Bioinformatics
• Causal Inference
• Learning Theories, Principles and Algorithms
• Collaborative Learning

Over the years, APTIKAL has also been a fertile ground for technology transfer and startup creation, with several projects moving toward industrial impact, among which Treensight, a data exploration and visualisation platform; XPdeep, which develops explainable deep learning models; and Echo, which focuses on machine-learning-based information retrieval.
