To try to decrease the preference of the attribute values for information gain and information gain ratio, in the paper, the authors puts forward a improved algorithm of C4.5 decision tree on the selection classification attribute. The basic thought of the algorithm is as follows: Firstly, computing the information gain of selection classification attribute, and then get an attribute of the information...
Automatically generating unit tests is a powerful approach to exercise complex software. Unfortunately, current techniques often fail to provide relevant input values, such as strings that bypass domain-specific sanity checks. As a result, state-of-the-art techniques are effective for generic classes, such as collections, but less successful for domain-specific software. This paper presents TestMiner,...
Automatic loop-invariant generation is important in program analysis and verification. In this paper, we propose to generate loop-invariants automatically through learning and verification. Given a Hoare triple of a program containing a loop, we start with randomly testing the program, collect program states at run-time and categorize them based on whether they satisfy the invariant to be discovered...
Link prediction plays an important role in complex network analysis. It is to predict the existence of an unknown link or a future link in a network. Classical methods for link prediction evaluate the similarity of vertices based on common neighbors, and denote that every common neighbor makes equal contribution to the connection likelihood. However, common neighbors may play different roles depending...
Simulating/Measuring the jitter tolerance of clock and data recovery (CDR) circuits, and confirming if the associated jitter tolerance meets the required specification for a specified communication standard, is an important consideration for designing/testing high-speed serial link interface circuits. However, conducting such performance evaluations are costly and time-consuming. In this paper, a...
Plant health is an essential factor to reduce the number of import in a country. In this research, we use paddy as an example to understand plant health. Our research is motivated by our belief that technology might aid in reducing chances of failed paddy harvest in Indonesia. To understand the plant health of paddy, we designed unmanned aerial vehicle (UAV) integrated pocket cameras to record near...
The main approach to solve hyperelliptic curve DLP is index calculus algorithm. One of the most important steps is to obtain relations among the factor basis elements. Although Nagao and Joux proposed decomposition methods respectively, their algorithms required solving a multi-variate system of non-linear equations. We propose a new method to find the relations among factor basis elements for a class...
To assess the multi-state of a rolling bearing more effectively and simultaneously, a unified assessment method is proposed based on chaos fruit fly optimization algorithm hyper-sphere support vector machine (CFOA-HSVM) two measures combination. Aiming to the blindness of parameters selection for HSVM, multiple parameters of HSVM can be searched the optimal values using chaos theory combined with...
In the government agencies, civil servants are required to have competence or ability to finish the work effectively and efficiently. In fact, the decision-making system for determining position and assignment of civil servants' functional works is still performed manually, so it takes a longer time. Moreover, the results are not totally accurate in terms of their competency. Rough set, hereinafter...
Spreadsheets often contain faults that are difficult to localize. Spectrum-based Fault Localization (SFL) assists users in the fault localization process by ranking cells by their suspiciousness to contain a fault. Since the ranking of the basic SFL approach is often imprecise, we propose three techniques to improve it, i.e., dynamic cones, grouping, and tie-breaking. We evaluate these techniques...
Multifunctional information system for long remote monitoring and correction of the health state of people with the use of the advanced mobile communications, intelligent medical gadgets (navigators) and mobile applications for health control is proposed.
Meeting the communication needs of individuals requires an understanding of the contexts where they use materials. Addressing this objective requires an understanding of the complex contexts in which patients use such materials. A modified version of script theory can address such situations.
This article reports study results in which participants (n=145) responded to a variety of negative messages in a variety of message channels, visual, textual, and verbal. Participants participated in A-B testing of distinct message strategies and then identified communication values that seemed most important in distinct message contexts. Results showed very clear differences between two broad classes...
In this paper, a new global time series averaging method is proposed for improving k-means clustering performance for observed signals or time series data. The proposed method is different from most commonly used time series averaging methods, such as pairwise averaging method (PA), nonlinear alignment and averaging filter (NLAAF), prioritized shape averaging (PSA) and dynamic time warping (DTW) barycentre...
This paper employs equal-image-size source partitioning techniques to derive the capacities of the general discrete memoryless wiretap channel (DM-WTC) under four different secrecy criteria. These criteria respectively specify requirements on the expected values and tail probabilities of the differences, in absolute value and in exponent, between the joint probability of the secret message and the...
In this paper, we consider the identity testing problems in the distributed setting, in which each terminal has data only relates to one random variable. Each terminal sends zero-rate message to the decision maker, and the decision maker decides the distribution of (Xn, Yn), which is indirectly revealed from the encoded messages, is the same as or λ-far from a given distribution. Interpreting this...
Light fingertip contact with an earth-fixed referent decreases body sway. In a previous study Johannsen et al. (2014) demonstrated longer return-to-baseline of body sway for intermittent contacts of more than 2 seconds duration. This indicates that sway reduction with light tactile contact involves postural control strategies independent of the availability of tactile feedback and may depend on the...
In the increasingly fierce competition of the colleges and universities, how to improve the teaching quality and enhance the competitiveness has become an important issue to every colleges and universities. Universities are trying to build scientific and perfect ideological and political classroom teaching quality evaluation system. AHP (Analytic Hierarchy Process) is based on the combination of quantitative...
In P300 speller brain-computer interface (BCI), the stimulus sequence is presented to subject for several rounds to achieve reliable P300 detection. Traditionally, the number of rounds is fixed and relatively large (e.g., 15 in the Wadsworth Dataset of BCI Competition 2005), which results in low information transfer rate. In order to improve the speed of character recognition without affecting the...
This article deals with the possible ways of overcoming untrafficable terrain. The mobility is one of the most important assumption of successful task-fulfillment of the army. The basic requirement for planning of the movement of the troops is the evaluation of terrain trafficability. In the case of untraffiacable terrain there is the need to accept measures to negotiate this area by planning detours...
