The meeting will be in the old library B5.1 (one floor above the bar). Professors Lizy John and Eugene John will give two brief presentations (a little over 30 minutes), and then we will (possibly) have the opportunity to hold individual meetings with people who wish to make contact. They seek to establish new research partnerships. Please remember that there are several funding sources available, including the <a href="https://utaustinportugal.org/" class="">Portugal-UT Austin</a> programme.</div><div class=""><br class=""></div><div class="">Biographies and abstracts follow below. Please try to attend if somehow this approaches your topics of interest. You are all welcome!</div><div class=""><br class=""></div><div class="">Best wishes,</div><div class="">—</div><div class="">Gabriel Falcão</div><div class=""><br class=""></div><div class=""><br class=""></div><div class=""><br class=""></div><div class="">================== </div><div class=""><b style="font-size: 14px;" class=""><span lang="EN-US" class="">Hardware for ML and ML for Hardware  </span></b></div><div class=""><br class=""></div><div class="">Prof. Lizy Kurian John, UT Austin </div><div class=""><br class=""></div><div class="">The emerging machine learning applications put exploding demands on hardware systems, and it is important to deliver high throughput, strong security, low latency and low energy consumption, in order to sustain the thriving development of cognitive systems and applications. Designing efficient circuits and systems to enable, support, and harness the power of machine intelligence is important to keep the present momentum of intelligent systems. In this talk, I will describe some of our research on providing efficient hardware infrastructure for ML. </div><div class="">In addition to designing systems for ML, we also conduct research on using ML in designing and evaluating systems. In this talk I’ll describe a few examples on using ML for pre-silicon performance evaluation during design of computer systems. </div><div class=""><span lang="EN-US" style="text-align: justify; background-color: white;" class=""><b class=""><br class=""></b></span></div><div class=""><span lang="EN-US" style="text-align: justify; background-color: white;" class=""><b class=""><br class=""></b></span></div><div class=""><span lang="EN-US" style="text-align: justify; background-color: white;" class=""><b class="">Bio: </b></span><span style="text-align: justify; background-color: white;" class="">Lizy Kurian John  is Truchard  Foundation Chair in Engineering at the University of Texas at Austin.

Irregular heartbeat or arrhythmia is one among many reasons for cardiovascular diseases. Arrhythmia detection and classification is critical in the treatment of irregular heartbeats. We present a systematic method for high accuracy arrhythmia detection and classification using ArrhyNet, a custom convolutional neural network (CNN) for arrhythmia classification on MIT-BIH Arrythmia Database. High and low frequency noise in the data is eliminated using low pass filter and baseline wander filter respectively, feature extraction is achieved using Daubechies Wavelet Transform and finally Synthetic Minority Over Sampling (SMOTE) technique is utilized to overcome the issue of imbalanced dataset.</span><span style="text-align: justify;" class="">  </span><span style="text-align: justify;" class="">Using our technique, 16 different types of arrhythmias distributed in Association for Advancement of Medical Instrumentation (AAMI) standard were analyzed.</span><span style="text-align: justify;" class="">  </span><span style="text-align: justify;" class="">The results indicate that the top-1 accuracy of our five-class classification system for the database used is 92.73%.</span><span style="text-align: justify;" class="">  </span><span style="text-align: justify;" class=""> </span></div><div class=""><b style="text-align: justify;" class=""><span lang="EN-US" style="line-height: 107%;" class=""><br class=""></span></b></div><div class=""><b style="text-align: justify;" class=""><span lang="EN-US" style="line-height: 107%;" class=""><br class=""></span></b></div><div class=""><b style="text-align: justify;" class=""><span lang="EN-US" style="line-height: 107%;" class="">Short Bio:</span></b><span lang="EN-US" style="text-align: justify;" class=""> Eugene B.
