talks
Google Summer of Code presentation - Athens Floss Meetup
Presented Google Summer of Code 2018 work for the project: “Adding Greek Language to spaCy” under the GFOSS — the Open Technologies Alliance.
Athens Crossroad: Machine Learning and Healthcare
In this talk, the latest advancements regarding the application of Artificial Intelligence on the field of Medicine are discussed at a roundtable session for the Athens Crossroad (12th Congress of the Hellenic Society of Thoracic & Cardiovascular Surgeons) conference, under the theme “Artificial Intelligence”. Use cases of Natural Language Processing algorithms, Brain Computer Interfaces and Deep Learning Architectures for Image Processing are outlined.
Improving sparse transformer models for efficient self-attention
One disadvantage of using attention layers in a neural network architecture is that the memory and time complexity of the operation is quadratic. This talk tries to address the following question: “Can we design attention layers with lower complexity that are able to discover all dependencies in the input?”. The answer seems to be yes, by modeling the problem of introducing sparsity to the attention layer with Information Flow Graphs.
