Short bio

Since 2015 Severin Gsponer is a PhD student at the Insight Centre for Data Analytics at the University College Dublin, Ireland. He holds a MSc (2014, University of Basel, Switzerland) and a BSc (2012, University of Basel, Switzerland) in Computer Science.
His current research focuses on sequence regression, in particular the analysis of different loss functions and convex optimization strategies within the sequence learning framework SEQL. In this context, he is especially interested in the scalability as well as the interpretability of the produced models. Additionally he works on improvements regarding feature selection strategies in huge feature spaces with structure, such as n-gram spaces. Severin Gsponer is also interested in a variety of other Computer Science related topics such as: recurrent neural networks, feature learning, multitask learning, transfer learning, bioinformatics, evolutionary computing, repoducibility in research and exascale computing.

    Newsletters

    These newsletters provide a good overview over the mass of article and news in the field of ML and AI:

    • ML Weekly - Gathering of ML related Twitter, Facebook, Google+, and LinkedIn posts.
    • AI Weekly - Similar to ML Weekly but for the field of AI.
    • Data Elixir - Curated news and resources about data science.
    • Import AI - A newsletter about artificial intelligence.

    These mailing lists contain recent announcements and CfP and are probably more interesting for researchers and people working in academia.

    • Connectionists - Mailing list about neural networks and cognitive or computational neuroscience.
    • ML-News - Google group for announcements and CfP for the machine learning community.
