[AllUsers-ISR] Talk next Wednesday at 4pm - Lizy John & Eugene John from UT/Austin e UT/San Antonio

[Gabriel Falcao]

Caros colegas, alunos e investigadores do DEEC-UC,

Pelas 16h do próximo dia 24 de maio (quarta-feira) decorrerá na antiga biblioteca B5.1 (por cima do bar) um encontro com professores da UT/Austin e UT/San Antonio. Os professores Lizy John e Eugene John farão duas brevíssimas apresentações (pouco mais de 30 minutos), e depois teremos (possivelmente) oportunidade de realizar encontros individuais com investigadores que queiram fazer a ponte. Eles procuram estabelecer novas parcerias. Recordo que existem várias fontes de financiamento, incluindo via programa Portugal-UT Austin <https://utaustinportugal.org/>. 

Seguem as biografias e abstracts. Apareçam para mostrarmos força at UC. São todos bem-vindos! 

Cumprimentos,

p.s.: Pedia o favor de divulgarem estas talks pelos vossos centros de investigação. Obrigado!

Dear colleagues, students and researchers at DEEC-UC,

Next May 24th (Wednesday) at 4pm we will be visited by two professors from UT/Austin and UT/San Antonio. 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 Portugal-UT Austin <https://utaustinportugal.org/> programme.

Biographies and abstracts follow below. Please try to attend if somehow this approaches your topics of interest. You are all welcome!

Best wishes,

Hardware for ML and ML for Hardware  

Prof. Lizy Kurian John, UT Austin 

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. 
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.

ArrhyNet: A High Accuracy Arrhythmia Classification Convolutional Neural Network

Prof. Eugene John, UT San Antonio

Cardiovascular diseases are one of the major causes of all human deaths. 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.  Using our technique, 16 different types of arrhythmias distributed in Association for Advancement of Medical Instrumentation (AAMI) standard were analyzed.  The results indicate that the top-1 accuracy of our five-class classification system for the database used is 92.73%.
