In this paper we introduce multi-label ferns, and apply this technique for automatic classification of musical instruments in audio recordings. We compare the performance of our proposed method to a set of binary random ferns, using jazz recordings as input data. Our main result is obtaining much faster classification and higher F-score. We also achieve substantial reduction of the model size.

The study investigates the role of financial sector in mobilization oil resources for development Nigerian economy. While period covers between 1981 and 2019, research utilizes principal component analysis (PCA) approach to construct a composite proxy from five variable indicators. Also, deploys fully modified ordinary least squares (FMOLS) estimate impact revenue on Nigeria’s economic growth. ...

The ability to continually gain customer loyalty in the midst of increasing competition, bargaining power and trust through appropriate business level strategies is a consistent challenge for service firms. This necessary order firms remain competitive increase growth. study therefore examined selected Nigeria. Quantitative method survey research design was employed study. primary population tw...

Context. Among optical stellar interferometers, the CHARA Array located at Mt Wilson in California offers the potential of very long baselines (up to 330 m) and the prospect of coupling multiple beam combiners. This paper presents the principle and the measured performance of VEGA, Visible spEctroGraph and polArimeter installed in September 2007 at the coherent focus of the array. Aims. With 0....

Given a power q of a prime number p and “nice” polynomials f1, . . . , fr ∈ Fq[T, X] with r = 1 if p = 2, we establish an asymptotic formula for the number of pairs (a1, a2) ∈ Fq such that f1(T, a1T + a2), . . . , fr(T, a1T + a2) are irreducible in Fq[T ]. In particular that number tends to infinity with q. MR Classification: 12E30 Directory: \Jarden\Diary\BSJ 23 December, 2011 * Alexander von ...

A half century of empirical work attempting to predict the factor content of trade in goods has failed to bring theory and data into congruence. Our study shows how the Heckscher-Ohlin-Vanek theory, when modified to permit technical differences, a breakdown in factor price equalization, the existence of nontraded goods, and costs of trade, is consistent with data from ten OECD countries and a r...

This document describes the participation of the INGEOTEC team in SENTIPOLC 2016 contest. In this participation two approaches are presented, B4MSA and B4MSA + EvoDAG, tested in Task 1: Subjectivity classification and Task 2: Polarity classification. In case of polarity classification, one constrained and unconstrained runs were conducted. In subjectivity classification only a constrained run w...

Let k be an arbitrary field, and C be a curve in A defined parametrically by x1 = f1(t), . . . , xn = fn(t), where f1, . . . , fn ∈ k[t]. A necessary and sufficient condition for the two function fields k(t) and k(f1, . . . , fn) to be same is developed in terms of zero-dimensionality of a derived ideal in the bivariate polynomial ring k[s, t]. Since zerodimensionality of such an ideal can be r...
