Inferring activities on smartphones is a challenging task. Prior works have elaborated on using sensory data from built-in hardware sensors in smartphones or taking advantage of location information to understand human activities. In this paper, we explore two types of data on smartphones to conduct activity inference: 1) Spatial-Temporal: reflecting daily routines from the combination of spatial...
Web data extraction is an essential task for web data integration. Most researches focus on data extraction from list-pages by detecting data-rich section and record boundary segmentation. However, in detail-pages which contain all-inclusive product information in each page, so the number of data attributes need to be aligned is much larger. In this paper, we formulate data extraction problem as alignment...
With the complexity big data platform architectures, data engineer provides the infrastructure with computation and storage resource for data scientist and data analyst. With those supports, data scientists can focus their domain problem and design the intelligence module (e.g., prepare the data, select/train/tune the machine learning modules and validate the result). However, there is still a gap...
Wireless sensor networks include a set of sensors being network nodes and a base station. The objective of such systems is to monitor changes which might occur at targets' location. Consequently, assuring the network connectivity is compulsory to maintain a continuous monitoring of given set of targets. However, sensor nodes sometimes stop functioning due to being physically damaged or running out...
IoT systems collect vast amounts of data which can be used in order to track and analyze the structure of future recorded data. However, due to limited computational power, bandwith, and storage capabilities, this data cannot be stored as is, but rather must be reduced in such a way so that the abilities to analyze future data, based on past data, will not be compromised. We propose a parameterized...
Entity tasks, such as linking, integration, and translation, are crucial for many search and NLP applications. For this purposed entity graphs have been manually built or automatically harvested. In this paper, we survey existing approaches abstracting these problems into a graph-based iterative matching on a pair of entity graphs.
Snake game is a computer action game, whose goal is to control a snake to move and collect food in a map. In this paper we develop a controller based on movement rating functions considering smoothness, space, and food. Scores given by these functions are aggregated by linear weighted sum, and the snake takes the action that leads to the highest score. To find a set of good weight values, we apply...
This paper addresses the multiobjective permutation flow shop scheduling problem, where makespan and total flow time are to be minimized simultaneously. We solve the problem by an extended version of the multiobjective evolutionary algorithm based on decomposition (MOEA/D). We investigate the effects of scalarization functions and the replacement mechanism. We also incorporate local search into MOEA/D...
In numerous different types of games, the real-time strategy (RTS) ones have always been the focus of gaming competitions, and in this regard, StarCraft can arguably be considered a classic real-time strategy game. Currently, most of the artificial intelligence (AI) players for real-time strategy games cannot reach or get close to the same intelligent level of their human opponents. In order to enhance...
