In this paper we study the inference of the kinetic Ising model on sparse graphs by the decimation method. The decimation method, which was first proposed in Decelle and Ricci-Tersenghi [Phys. Rev. Lett. 112, 070603 (2014)] for the static inverse Ising problem, tries to recover the topology of the inferred system by setting the weakest couplings to zero iteratively. During the decimation proces...

This paper presents the implementation of two stage FIR (Finite Impulse Response) decimation filter using system generator and it is compared with single stage implementation of FIR filter for WiMAX Application. FIR filter with decimation factor M is subdivided into two decimation factors M1 and M2. The two different FIR filters are designed with different coefficient values and different sampl...

| Using an ensemble of classi ers instead of a single classi er has been demonstrated to improve generalization performance in many di cult problems. However, for this improvement to take place it is necessary to make the classi ers in an ensemble more complementary. In this paper, we highlight the need to reduce the correlation among the component classi ers and investigate one method for corr...

The demand for new telecommunication services requiring higher capacities, data rates and different operating modes have motivated the development of new generation multi-standard wireless transceivers. A multi-standard design often involves extensive system level analysis and architectural partitioning, typically requiring extensive calculations. In this research, a decimation filter design to...

1. INTRODUCTION In multistandard receivers, the hardware should be configurable or programmable for the reception of different types of signals having different symbol rates. After the AD conversion, utilizing commonly the delta-sigma AD-conversion principle and high oversampling ratio, the sampling rate is reduced to be a low integer multiple of the symbol rate. In this decimation, the desired...

We present an out-of-core mesh decimation algorithm that is able to handle input and output meshes of arbitrary size. The algorithm reads the input from a data stream in a single pass and writes the output to another stream while using only a fixed-sized in-core buffer. By applying randomized multiple choice optimization, we are able to use incremental mesh decimation based on edge collapses an...

Color image interpolation using Directional-Vector Rat.ional Filters (DVRF) is investigated in this paper. We study this problem (or the upsaapling problem) for two decimation schemes that are most commonly used in practice:( 1) rectangular decimation (every-other-row and every-other-column sub-sampling) and (2) Quincunx decimation. For each decimation lattice, we present an adaptive re-samplin...
