Abstract:

Constructive Adaptive User Interfaces and Empathic Computing
Prof. Masayuki Numao

We demonstrate a method to locate relations and constraints between a music score and its impressions, by which we show that machine learning techniques may provide a powerful tool for composing music and analyzing human feelings. We examine its generality by modifying some arrangements to provide the subjects with a specified impression. This demonstration introduces some user interfaces, which are capable of predicting feelings and creating new objects based on seed structures, such as spectrums and their transition for sounds that have been extracted and are perceived as favorable by the test subject. We call them constructive adaptive user interfaces (CAUI), introduce them a brain computer interface, and discuss their relation to Empathic Computing.

As the premiere human language technology center in the country, we present the diverse research activities of the Natural Language Processing Laboratory of the College of Computer Studies, De La Salle University, focusing mainly on the projects that we have embarked on. These projects include the formal representation of human languages and the processes involving these languages. Language representation entails the development of language resources such as lexicons and corpora for various human languages including Philippine languages, across various forms such as text, speech and video files. Applications on languages that we have worked on include Machine Translation, Question-and-Answering Systems, Information Extraction, Natural Language Generation, Automated Text Summarization and Simplification, and Language Education. These applications provide the current human language interface for communication, searching, and learning, to name a few.

Keywords: Natural Language Processing, Human Language Technology

Tracking moving objects from a video sequence requires segmentation of these objects from the background image. However, getting the actual background image automatically without object detection using only the video is difficult. In this paper, we describe a novel algorithm to generate background from real world images without foreground detection. The algorithm assumes that the background image is shown in the majority of the video. Given this simple assumption, the method described in this paper is able to accurately generate, with high probability, the background image from a video using only a small number of binary operations.


Keywords. Boolean mode, background modeling, video segmentation.

Here we derive formulas for the number of ways of tiling a (mxn) rectangle using (1x2) tiles, for m = 1, 2, 3, and 4. The cases when m > 4 are reserved for future versions of this paper. Further we give a C++ program that solves the general problem of tiling the (mxn) rectangle using (hxk) tiles, where 1£h£m and 1£k£n and h,k,m,n are all integers. The program counts the number of ways the tiling can be done, and optionally lists the tilings themselves.

Keywords. Tiling, rectangular tiles, C++ recursion.

Title: "Dynamic Load Balancing Algorithms for Embarrassingly Parallel Tasks"

Abstract:

Abstract. Many scientific applications are considered embarrassingly parallel because they contain loops with large numbers of independent iterations that are computationally intensive. Given a loop with $n$~iterations and $p$~processors, the obvious scheduling is to assign $n/p$~iterates per processor. However, the respective execution times of each iterate could vary due to conditional statements or variable amount of computation required. Even in applications where there is minimal code variation in each iterate, the iteration execution times may vary due to differences in effective processor speeds, latency in network traffic, latency in data access from primary and secondary memories, daemons waking up, or hardware interrupts. The cumulative effect of variances in iterate execution times could ultimately result to processor load imbalance and therefore to severe performance degradation of parallel applications at runtime. For effectively load balancing scientific parallel applications, algorithms for scheduling iterates with variable execution times have been studied such as fixed-size chunking, guided self scheduling, factoring, weighted factoring, adaptive weighted factoring, and adaptive factoring. In this paper, these algorithms are presented and compared in terms of two metrics over an increasing~$p$ , the parallel cost and the coefficient of variation of processor finishing times. The performance measurements were implemented using two scientific applications as test beds: The many-body simulation and the profiling of automatic quadrature routines.

Keywords: embarrassingly parallel tasks, parallel loops, dynamic load balancing
