Combiner and Stacked Generalization are two very similar meta-learning methods that combine predictions of multiple classiiers to improve accuracy of any single classiier. In this paper, we compare stacked generalization and combiner from the perspective of training eeciency versus accuracy. We show that both methods improve the accuracy of any single classiier roughly at an equivalent level. M...

Symmetry is essential in the design of complex systems like Metaverse Transportation Sys-tem (MTS) and helps ensure that all components work together effectively. In development a microstrip diplexer for 5G-enabled IoT MTS, maintaining symmetry crucial to achieving flat responses with low group delays. By integrating transportation technology Metaverse, System can greatly improve effectiveness ...

where Jν(x) is the Bessel function of the first kind of order ν [1], and =z denotes the imaginary part of z. An extensive table of integral transforms involving the Bessel functions in the kernels is collected in [6]. Since the integration in (2) is with respect to the order of the Bessel function, such a pair of integral transforms is called index transform. Details about many other index tran...

design and optimization of a single crystalline silicon (c-si) solar cell is performed to achieve the maximum light conversion efficiency. various parameters such as doping concentration and thicknesses, and geometrical dimension of surface pyramids are studied. the inverted surface pyramid is used to increase the efficiency of the solar cell, and engineered oxide layer is used as the passivati...

in this paper, downlink resource allocation for a sparse code multiple access (scma) based heterogeneous  cellular networks (hcn) is investigated. the main aim of this paper is to obtain joint power allocation and codebook assignment to achieve the least total system transmit power. in this regard, the proposed objective function is formulated as total transmit power subject to users minimum ra...

Text workers should find ways of representing huge amounts of text in a more compact form. Textual documents can be represented by concepts. One way to define the concepts is by the terms, keywords extracted from the textual documents and cleaned by several processes like stopwords and stemming. Using the frequencies of the terms, one can quantify the relations between documents or portions of ...

This paper proposes an idea to modify the conventional Wilkinson power dividers to have physically spaced output ports. The well-known internal resistor of Wilkinson power divider is now connected to output ports by two additional transmission lines to create a triangular shape power divider. Several modified power dividers are designed at frequency of 1.0 GHz and one of them is fabricated and ...

The paper presents a first step towards family index theorem for classical self-adjoint boundary value problems. We address here the simplest non-trivial case of manifolds with boundary, namely two-dimensional manifolds. result is an families order elliptic differential operators local conditions, parametrized by points compact topological space $X$. compute $K^1(X)$-valued in terms data over b...
