Diversity or complementarity of experts in ensemble pattern recognition and information processing systems is widely-observed by researchers to be crucial for achieving performance improvement upon fusion. Understanding this link between ensemble diversity and fusion performance is thus an important research question. However, prior works have theoretically characterized ensemble diversity and ...

Machine learning offers a fantastically powerful toolkit for building useful complex prediction systems quickly. This paper argues it is dangerous to think of these quick wins as coming for free. Using the software engineering framework of technical debt, we find it is common to incur massive ongoing maintenance costs in real-world ML systems. We explore several ML-specific risk factors to acco...

A curriculum is a planned sequence of instructions or a view of the student’s experiences in terms of the educator’s or school’s instructional goals. However, the guidance provided by the curriculum is limited and both student and course counsellor struggle with the question of choosing a suitable course at a proper time. Many researchers have focused on making course recommendations with tradi...

the purpose of this study is to determine spatial dependency pattern of systematic risk of dry land wheat production in iran, using spatial autoregressive models. to this end, spatial weighted contiguity matrix was constructed based on the delaunay triangularization method, and correlation coefficient among these neighbors were estimated using spatial autoregressive models. in addition, the rol...

Aspects avoid tangled solutions for cross-cutting design concerns. However, there are various reasons why it may be hard to use an aspect language as a solution, even though developers are faced with cross-cutting design concerns. For instance, certain limitations of specific aspect composition (or weaving) mechanisms may hinder the use of aspects or the use is cumbersome. Or because of particu...

This paper describes a grammatical formalism, DepPattern, to write dependency grammars using Patterns of PoS tags augmented with lexical and morphological information. The formalism inherits ideas from Sinclair’s work and Pattern Grammar. In addition, a compiler was implemented so as to generate robust parsers from DepPattern grammars for 5 languages: Spanish, English, Galician, Portuguese, and...

This paper incorporates morphological markedness constraints into a framework in which morphology and phonology directly interact, modeled with interleaving of morphological and phonological constraints in serial OT (Wolf 2008, 2009). Morphological markedness constraints are constraints against realization (or spell-out) of morphologically marked feature sets. The empirical data motivating this...

Import dependency and the extent of renewable gas production are two outcomes of interest concerning the future of gas supply in the Netherlands. Due to the complexity of internal mechanisms and uncertainties associated with the natural gas production, the production of renewable gases, and the demand for gas, the future of these two outcomes of interest cannot simply be projected. In this stud...

[1] High-frequency physical observations from 40 temperate lakes were used to examine the relative contributions of wind shear (u*) and convection (w*) to turbulence in the surface mixed layer. Seasonal patterns of u* and w* were dissimilar; u* was often highest in the spring, while w* increased throughout the summer to a maximum in early fall. Convection was a larger mixed-layer turbulence sou...
