In this episode we have invited Albert Bifet who is here to talk about open source in relation to AI. He is currently a guest professor at Halmstad University and is known for his work and research on machine learning for data streams, a field which he has nearly 20 years of experience in. Albert has been working on the development of open source software like Moa, Weka and River. In this episode we both discuss the benefits and risks with open source - and what should be open and what not.
