News and Announcements

Theory Days 2019

Synopsis:

Theory Days 2019 celebrates two main reasons: 12 years of Algorithms and Complexity at the Department of Computer Science in UP Diliman, as well as 107 years since the birth of Alan Turing. Theory Days 2019 aims to celebrate both these reasons by providing invited talks under the general theme of discrete mathematics and theoretical computer science and their related practice.

Talks and other activities in Theory Days 2019, such as brainstorming or break-out sessions, are largely informal in nature: the main reason is to initiate discussions which may lead to (in)formal collaborations, conference or journal articles, open problems for (under)graduate students and the computing community, or just for fun!

Coordinates:

24 to 25 June 2019, 9AM to 5PM, ERDT room, 2nd floor, Alumni Engineers Centennial Hall, College of Engineering, UP Diliman, Quezon city.

Oral defense for MSc Computer Science degree of Ren Tristan A. De La Cruz with the following details:

Title: On String Languages Generated by Spiking Neural P Systems with Structural Plasticity

Abstract: Membrane computing is a field of computer science that studies unconventional models of computa- tion known as P systems which are inspired by the biological and chemical processes in a biological cell or group of cells. In 2006, a model of computation known as spiking neural P system (SNP system) was introduced. SNP systems were inspired by networks of spiking neurons. In 2015, a variant of SNP systems known as spiking neural P system with structural plasticity (SNPSP sys- tem) was introduced. SNPSP systems incorporate the ideas of synaptogenesis and synaptic pruning (structural plasticity) as features of the model. To study structural plasticity as feature of SNPSP systems, we used SNPSP systems to generate families of languages in the Chomsky hierarchy: finite languages, regular languages, context-free languages, and recursively enumerable languages. We created procedures for constructing SNPSP systems that generate the families of languages. We discussed how structural plasticity is used for constructing the language generator SNPSP systems. We also compared the language generator SNPSP systems to existing language generator SNP systems.

Keywords: Natural computing, Membrane computing, Spiking Neural P Systems with Structural Plasticity, SNPSP Systems, Models of computation

16 June 2017

The Algorithms and Complexity lab (in short, AClab) is celebrating Theory Days from 22 to 23 June 2017. The two main reasons for the celebration of the Theory Days (open to the general public) are to celebrate the 10th anniversary of AClab, and the 105th birthday of Alan Mathison Turing (the founder of computer science). Theory Days aim to celebrate both these reasons by providing invited lectures under the general theme of discrete mathematics and theoretical computer science.

More details regarding this celebration can be found at the Theory Days 2017 page.

Title: Showing the Correctness of Algorithms using

Machine Learning and Automated Reasoning

by

Dr. Cezary Kaliszyk Uni. Innsbruck

Abstract:

With the increasing complexity of software and hardware, showing the correctness and security of the involved algorithms becomes more and more important. Highest levels of certainty about such properties can today be achieved using formal proof methods. In this talk I will introduce formal proof and discuss the main challenges the field faces presently. The most powerful techniques today combine machine learning with automated reasoning. I will introduce the various machine learning problems including the selection of relevant knowledge, choice of reasoning techniques, and generation of intermediate statements, as well as discuss the currently used algorithms and their relation to reasoning.

Bio: Cezary Kaliszyk is a researcher at the University of Innsbruck, Austria. His main interests are providing proof advice and automation for formal proof. He received a MSc from the University of Warsaw, Poland in 2005, and a PhD in computer science in 2009, from the Radboud University, Netherlands. He spent a year at the Technical University of Munich working with nominal logic in the Isabelle proof assistant, two years at the University of Tsukuba, and has been working in the Computational Logic group in Innsbruck, Austria since 2012. He has been a recipient of grants from the European Research Council, Austrian Science Fund, Japan Society for the Promotion of Science, Austrian Agency for International Cooperation. His industry experience includes working at Google Research as a faculty advisor.
