Hi, everybody! I'm John. My friends and my godfather call me Johnny, and here are some things you need to know about me. Born and raised in Eleftheroupoli (Liberty City in English * * * GTA vibes * * *) of Kavala, Greece, on 7 May 1996, in a unique, but above all, extremely good family. I've been crazy about everything tech since my younger age. After graduating from my high school, I graduated from the Aristotle University of Thessaloniki with a Bachelor's degree and a Master's degree in Informatics. Right now, I am a PhD student at the same university in the field of Explainable Artificial Intelligence, and specifically Interpretable Machine Learning, and I am a member of the Intelligent Systems Lab. My love of technology is limitless, which is why I research this area continuously. My vision is to work in the future for Apple Inc.

Education

ProVictus

The goal of this project is the transfer of knowledge in the field of predictive maintenance to Link Technologies SA in order to apply it for public transportation vehicles. The project involves the execution of a knowledge transfer plan that will study the current capabilities of the company, but also the actions it must follow, in order to succeed in solving the problem of predictive maintenance in public transport.

ETHOS: a multi-label hate speech detection dataset

Ioannis Mollas, Zoe Chrysopoulou, Stamatis Karlos, Grigorios Tsoumakas

Complex and Intelligent Systems, Springer

In this paper, we present ‘ETHOS’ (multi-labEl haTe speecH detectiOn dataSet), a textual dataset with two variants: binary and multi-label, based on YouTube and Reddit comments validated using the Figure-Eight crowdsourcing platform. Furthermore, we present the annotation protocol used to create this dataset: an active sampling procedure for balancing our data in relation to the various aspects defined.

LionForests: Local Interpretation of Random Forests

Ioannis Mollas, Nick Bassiliades, Ioannis Vlahavas, Grigorios Tsoumakas

NeHuAI-2020 Workshop of ECAI2020

In this paper, we provide a sequence of actions for shedding light on the predictions of the misjudged family of tree ensemble algorithms. Using classic unsupervised learning techniques and an enhanced similarity metric, to wander among transparent trees inside a forest following breadcrumbs, the interpretable essence of tree ensembles arises. An explanation provided by these systems using our approach, which we call "LionForests", can be a simple, comprehensive rule.

LioNets: Local Interpretation of Neural Networks through Penultimate Layer Decoding

Ioannis Mollas, Nick Bassiliades, Grigorios Tsoumakas

AIMLAI-XKDD at ECMLPKDD 2019

This paper explores a methodology on providing explanations for a neural network's decisions, in a local scope, through a process that actively takes into consideration the neural network's architecture on creating an instance's neighbourhood, that assures the adjacency among the generated neighbours and the instance.

Hatebusters: A Web Application For Actively Reporting Youtube Hate Speech

Antonios Anagnostou, Ioannis Mollas, Grigorios Tsoumakas

IJCAI-ECAI 2018

Hatebusters is a web application for actively reporting YouTube hate speech, aiming to establish an online community of volunteer citizens. Hatebusters searches YouTube for videos with potentially hateful comments, scores their comments with a classifier trained on human-annotated data and presents users those comments with the highest probability of being hate speech. It also employs gamification elements, such as achievements and leaderboards, to drive user engagement.
