Seeing is believing and humans rely on their sight to make decisions. As a result, a lot of data we gather in various ways is visual. It is natural to want to get the most out of the data we have and one method toward achieving this is semantic segmentation. In essence, semantic segmentation means figuring out which pixels belong to which type of object. For example, how can a machine recognize a pedestrian on a road crossing or differentiate between fields and swamplands? Deep Learning has helped make huge strides in the field of semantic segmentation but there are still many challenges to overcome!

Speakers and presentations:

• Dmytro Fishman, University of Tartu, Lecturer of Artificial Intelligence - Biomedical segmentation: holy grail and remaining mysteries
• Tanya Shtym, KappaZeta, Machine Learning Engineer - KappaMask: AI-Based Cloud Mask Processor for Sentinel 2
• Markus Kängsepp, University of Tartu, Autonomous Driving Lab, Junior Research Fellow - Calibration of Bird's-Eye-View Semantic Segmentation
• Kaupo Voormansik, KappaZeta, CEO - Data Science and Machine Learning in KappaZeta

The benefits arising from Artificial Intelligence (AI) in terms of prediction accuracy, automation, new products and services or cost reduction are remarkable. But enterprises need to build trust and transparency in the data and algorithm used in AI systems to increase adoption. By default, AI systems such as machine learning or deep learning produce outputs with no explanation or context. As the predicted outcomes turn into recommendations, decisions or direct actions, humans tend to look for justification. Most experts in the field agree that AI systems should be less ambiguous to the end-users and subjects of algorithmic decision-making. In this seminar, four speakers from the University of Tartu and Wise will discuss the explainability and transparency of AI as well as the requirements and challenges of building a robust machine learning system.

Speakers and presentations:

• Meelis Kull, Associate Professor in Machine Learning at UniTartuCS: Understanding the decisions of an AI system
• Radwa El Shawi, Associate Professor of Big Data at UniTartuCS: Towards automatic concept-based explanations
• Luca Traverso, Data Science Lead at Wise: Building robust and defensible machine learning systems in Fincrime
• Rain Vagel, Data Scientist at Wise: Why did the model decide X?
