  • This paper proposes the use of uncertainty reduction in machine learning methods such as co-training and bilingual bootstrapping, which are referred to, in a general term, as ‘collaborative bootstrapping’. The paper indicates that uncertainty reduction is an important factor for enhancing the performance of collaborative bootstrapping.

  • • Algorithm efficiency is considered with only big problem sizes. • We are not concerned with an exact measurement of an algorithm's efficiency. • Terms that do not substantially change the function’s magnitude are eliminated.

  • The temperature distribution from the top to the bottom of the network is determined by an infrared camera and then these results are adopted in the mathematical model algorithm. During the drying process, the series of images showing the phase change in network is observed and recorded, which will be processed with an algorithm built in MATLAB. From that, we find out the change of network saturation, drying rate and the increase in the number of clusters and in the size of the main cluster in network.

  • Estimation is one of four modeling problems. The other three are representation (how something should be modeled), measurement (which physical quantities should be measured and how they should be measured), and validation (demonstrating confidence in the model)

  • Collocational word similarity is considered a source of text cohesion that is hard to measure and quantify. The work presented here explores the use of information from a training corpus in measuring word similarity and evaluates the method in the text segmentation task. An implementation, the V e c T i l e system, produces similarity curves over texts using pre-compiled vector representations of the contextual behavior of words. The performance of this system is shown to improve over that of the purely string-based TextTiling algorithm (Hearst, 1997). 1 Background ...

  • Chapter 2 - Numeric attributes. In this chapter, we discuss basic statistical methods for exploratory data analysis of numeric attributes. We look at measures of central tendency or location, measures of dispersion, and measures of linear dependence or association between attributes. We emphasize the connection between the probabilistic and the geometric and algebraic views of the data matrix.

  • Chapter 12 - Pattern and rule assessment. In this chapter we discuss how to assess the significance of the mined frequent patterns, as well as the association rules derived from them. Ideally, the mined patterns and rules should satisfy desirable properties such as conciseness, novelty, utility, and so on. We outline several rule and pattern assessment measures that aim to quantify different properties of the mined results.

  • Chapter 17 - Clustering validation. In chapter 17, we describe various clustering validation and evaluation strategies, spanning external and internal measures to compare a clustering with the ground-truth if it is available, or to compare two clusterings. We also highlight methods for clustering stability, that is, the sensitivity of the clustering to data perturbation, and clustering tendency, that is, the clusterability of the data.

  • With the advent of multimedia, digital signal processing (DSP) of sound has emerged from the shadow of bandwidth-limited speech processing. Today, the main applications of audio DSP are high quality audio coding and the digital generation and manipulation of music signals. They share common research topics including perceptual measurement techniques and analysis/synthesis methods. Smaller but nonetheless very important topics are hearing aids using signal processing technology and hardware architectures for digital signal processing of audio.

  • The recent wide diffusion of (i) easy-to-use software tools for the implementation of Graphical User Interfaces (GUIs); and (ii) communication-oriented instrumentation, often provided with Ethernet interface, in addition to the more traditional GPIB and RS-232 ones, can be particularly exploited in the field of measurement teaching. It is well known, in fact, that for a better understanding of the teaching issues in such a field, the students have to practice with real instrumentation. The computer-based simulations are often inadequate to assure a good experience in that direction.

  • It is very difficult to determine what are the most popular of modern programming languages. Some languages are very popular for particular kinds of applications (e.g., COBOL is still strong in the corporate data center[citation needed], often on large mainframes, FORTRAN in engineering applications, scripting languages in Web development, and C in embedded applications), while some languages are regularly used to write many different kinds of applications. Also many applications use a mix of several languages in their construction and use.

  • RAM is consumed by TinyDB and forwarding buffers in the networking stack. We have also experimented with several other types of join queries and found similar re- sults: irrespective of the query, join-predicate selectivity and average node depth have the largest effect on query execution cost for the distributed join algorithm. For all graphs showing results for the distributed join al- gorithm, we show power utilization and result accuracy at steady state, after groups have formed and nodes are per- forming the join in-network.
