SUMMARY:Vortrag | Dr. Hendrik Strobelt, Harvard University SEAS
DESCRIPTION:  \n\n\n\nSprecher\nDr. Hendrik Strobelt,\nHarvard University SEAS\n\n\n\nTitel\n\n\nVisual Analysis for (Early) Discovery\n\n\n\n \n\nData Visualization is effectively used to explore and explain complex data. In the talk, I will\npresent three visual tools for different data domains that can help to formulate hypotheses in\nearly stages of data discovery:\n\nData often comes with categorical information that assigns each item to one or multiple sets.\nWe developed UpSet to explore the set intersections. Interactively, a user can filter and recombine\nintersections and calculate statistical measures on them. I will introduce the visual mapping and\nin a short demo, I will demonstrate the core features of our system.\nAcquisition of  biological data has become fast and cost-efficient. As a result, a domain\nscientist spends a large share of time in analyzing the experimental data. For example, RNAseq\nallows to sequence RNA which can then be used to investigate alternative splicing events within\ndifferent conditions (different patient groups, different human tissues). ‘Vials’ provides a visual\nanalysis tool to investigate this complex data. I will introduce the biological data, explain it’s\nmapping to visual  variables, and show a short demo of the interactive system.\nThe increased interest in neural networks and their common use imposes the question about the ‘\nHow ?’ - How do they work? What do they capture?. I will present a visual tool, LSTMVis, that\nallows investigation of state changes on trained models (LSTMs) and can be one puzzle piece in the\nquest of white-boxing neuronal networks.\n\nAll three projects resulted in open source tools which are used by domain experts to help them\nto generate hypothesis as a first step towards insight.\n\nSpeaker’s Bio\nHendrik Strobelt was postdoctoral researcher in the Visual Computing Group at Harvard SEAS. He\nwill join IBM research, Cambridge, US. He received his PhD in Computer Science from University of\nKonstanz, Germany and his MSc (Diplom) from TU Dresden, Germany.\nMore information about the speaker on:  \nhttp://hendrik.strobelt.com/Personal/index.html\n\n\n\n  \nSee  \nhttp://www.sfbtrr161.de/events/events.html for\nall events of the Collaborative Research Center/Transregio 161
