Random forests are one of the most successful ensemble methods which exhibits performance on the level of boosting and support vector machines. The method is fast, robust to noise, does not overfit and offers possibilities for explanation and visualization of its output. We investigate some possibilities to increase strength or decrease correlation of individual trees in the forest. Using sever...

The correlation coefficient (Pearson’s r) is one of the most frequently used tools in statistics. In this paper we discuss a correlation coefficient between Atanassov’s intuitionistic fuzzy sets (A-IFSs). We have constructed the coefficient so it provides the strength of the relationship between A-IFSs and also shows if the considered sets are positively or negatively correlated. Next, the prop...

Real-world performance of the ATSC DTV standard has been the subject of great interest and debate. In this paper, we report on a detailed study of reception at 34 sites in the Dallas-Ft. Worth region during September, 2000. We report on statistics such as field strength, service availability, system performance, building attenuation, site margin, and sensitivity to antenna placement. These test...

Lightning strikes to overhead transmission lines cause travelling waves which propagate along the overhead line and enter substations where they cause overvoltages which can pose a risk to any items of equipment connected, such as cables or transformers. With the use of metal-oxide arresters, these overvoltages are reduced to values which, taking into account an adequate safety margin, are belo...

ANDRILL completed its first season in 2006-07 drilling AND-1B through the McMurdo Ice Shelf (MIS) to a depth of 1,285m below the sea floor, a record for Antarctic margin drilling, with 99% recovery. The alternating glacial-interglacial sediment packages interbedded with volcanics provide a uniquely detailed record of Antarctic glacial and climatic change through the Neogene. This paper summariz...

In [4] an algorithm is presented for analytic phase margin control design. Without special care, however, the compensator computed with this algorithm may not be a real rational function. The problem is evident when the plant has real unstable poles. In this case the algorithm in [4] requires a mapping of real points into complex values, and it is not clear that the resulting compensator has re...

In this document we give a short overview of the reasons why Rijndael should be selected as the AES. We have divided our arguments into four categories: • Security: Rijndael has the same objective security level as the other finalists, and can easily be implemented in a secure way. • Efficiency: Rijndael has a large "performance margin" compared to the other candidates. • Design philosophy: The...

1 The central problem in the case of face detectors is to build a face class model. We present a method for face class modeling in the eigenfaces space using a large-margin classifier like SVM. Two main issues are addressed: what is the required number of eigenfaces to achieve a good classification rate and how to train the SVM for a good generalization. As the experimental evidence show, gener...

Sauer’s Lemma is extended to classes HN of binary-valued functions h on [n] = {1, . . . , n} which have a margin less than or equal to N on all x ∈ [n] with h(x) = 1, where the margin μh(x) of h at x ∈ [n] is defined as the largest non-negative integer a such that h is constant on the interval Ia(x) = [x− a, x+ a] ⊆ [n]. Estimates are obtained for the cardinality of classes of binary valued fun...
