Pictures from ISIC 2014 Special Session

Our special session at the ISIC 2014, "Performance and Power Issues in Multi/Many Core Architecture" took place on December 12, 2014 at Marina Bay Sands, Singapore. There were five oral presentations (including a video presentation), all from different countries, and active discussions involving audiences. Some of the pictures taken at the session are shown below. More pictures are also available at the ISIC photo gallery.

Pictures from Joana's Talk

On December 5, Joana Corte-Real from University of Porto visited Aizu and gave us a talk titled "Introduction to Inductive Logic Programming." The talk began with a brief introduction to the logic programming, or Prolog, as not many people are very familiar to this language (unlike 80's). For those who are interested, the slides are available at: this page.

The slides for the lecture on December 5

Joana Côrte-Real, who will give us a talk on December 5 (Friday) sent us two sets of slides to be used for her talk.

Brief Introduction to Prolog and Inductive Logic Programming .

Taking a look at these slides in advance should help you better understand the talk; or; for those who have not made a decision whether to attend the seminar, they would help you to make up your mind.

*The slides are subject to revision.

Special Session at ISIC 2014

As previously mentioned, we are going to organize a special session Performance and Power Issues in Multi/Many Core Architecture at ISIC 2014, which will take place in Singapore next month. The symposium schedule has been announced and our session will take place on December 12, from 1330 to 1500 in Room 4102 of Marina Bay Sands – Sands Expo and Convention Centre.

Special Lecture by Joana Corte-Real on 12/5

We are pleased to make a preliminary announcement of the special lecture by Ms Joana Corte-Real from University of Porto, Portugal.

The title and abstract of talk are attached at the bottom of this message.

The lecture is primarily targeted to the SCCP class (O3-019 A Peek Inside Computers), but we will make it open to general public.

Here are some information regarding the University of Porto and its relationship to Aizu:

• Aizu and Porto have an exchange program agreement.
• Dr Pedroso from Porto visited Aizu and gave us special lectures Link
• I myself visited Porto and introduced Aizu to Porto Link
• One of our students, Kazuaki Takahashi, visited Porto in 2009 and Dr Pedroso took care of him. Link Link
• A student from Porto, Rui Jorge Rei, was staying with us from January to April 2010 under JASSO scholarship support. Dr Pedroso is his supervisor. Link

Since the lecture is more than six week ahead, there may be a change of schedule and other details. We will keep you posted on this page.

Title

Introduction to Inductive Logic Programming

Abstract

Inductive Logic Programming (ILP) is a powerful but often neglected machine learning technique for extracting knowledge from observations; it consists of building a generalized logic model which explains a set of facts, to a degree of accuracy. The main advantage of ILP is its capability to provide classifiers that are interpretable by humans, which makes it popular in different scientific domains. This research area is quite relevant in several field such as knowledge acquisition, inductive program synthesis, inductive data engineering, and knowledge discovery in databases. Much work has been done on finding good models in ILP, but there is still a vast scope for improvements, in particular with respect to attaining faster execution times; because ILP systems must deal with enormous search spaces, they usually incur in non-trivial query checking times. To tackle this issue, it is possible to take advantage of the concurrent sections of the ILP algorithm and paralellize them so as to reduce execution time significantly; a strong case for the parallelization of the search space can be made: on the one hand, there are several sections of the ILP algorithm which could be executed concurrently without adding much to the complexity of the code; on the other hand, the fact that datasets are becoming too large to be stored in one s memory invites to the use of several machines connected in heterogeneous configurations such as clusters, grids or clouds.machine

Speaker's Bio

Joana Corte-Real is a PhD student of the joint Doctoral Program of Universities of Minho, Aveiro and Porto in Computer Science (MAP-i). She obtained her MSc degree from the Faculty of Engineering of University of Porto in 2013, in Computers and Electric Engineering. Her current interests are parallel and distributed computing and machine learning, in particular Inductive Logic Programming techniques. She developed a parallel version of a MapReduce construct for Prolog that obtains linear speed-ups in multicore machines. Currently, she has been researching on how to extend this implementation for hybrid shared and distributed memory architectures and one of the applications of this work is on Inductive Logic Programming. On her free time, she enjoys horse riding and takes german classes; she is also keen on traveling and meeting new people.

ISIC 2014

A paper titled "Case Study: Effectiveness of Dynamic Frequency Scaling on Server Workload" has been accepted for the presentation at The International Symposium on Integrated Circuits (ISIC) 2014.

ISIC-2014 will take place in Singapore in December and our paper will be presented within the special session Performance and Power Issues in Multi/Many Core Architecture.

Visit to Porto

Hitoshi Oi is visiting University of Porto, to work with Drs Pedroso and Dutra, and their colleagues and students.

Performance and Power Issues in Multi/Many Core Architecture

We are organizing a special session, titled "Performance and Power Issues in Multi/Many Core Architecture" within ISIC 2014, held in Singapore in December. Currently we are soliciting papers and the details are found at the special session web site.

Visit to CINVESTAV

Hitoshi Oi visited the Computer Science Department of CENTRO DE INVESTIGACIÓN Y DE ESTUDIOS AVANZADOS DEL IPN (CINVESTAV) in Mexico City, Mexico.

He introduced Aizu to the faculty members and gave a lecture to both faculty and graduate students*.

* CINVESTAV has only graduate programs.

Termination of Yahoo Groups (JP)

We used to use Yahoo Japan Group services, and two of them (listed at the bottom) are still active at present. However, due to the termination of the service by Yahoo Japan (in Japanese), our groups will also terminated on May 28, 2014.
