• Sentiment Analysis (SA) requires large human labeled data; which is costly to obtain. • Domain Adaptation(DA) techniques help in performing SA with minimum human labeled data. • Two techniques, Feedback EM and Rocchio SVM are proposed for data selection/filtering. • Use of Mutual Information(MI) and Cosine Distance(CD) to measure similarity between In and Out-Domain distributions.

We describe and apply a flexible, adaptive cosine packet transform to separate audio sources from instantaneous, underdetermined audio mixtures by time-frequency masking. Previously studied adaptive transform schemes have two main drawbacks: the signal can only be partitioned into dyadic intervals, and the profiles of the overlapping windows are often very short, thus tapering off very quickly....

This Paper Focus On Image Compression.It is used specially for the compression of images where tolerable degradation is required. With the wide use of computers and consequently need for large scale storage and transmission of data, efficient ways of storing of data have become necessary. Image compression is minimizing the size in bytes of a graphics file without degrading the quality of the i...

In this paper area efficient and cost effective techniques for design of pulse shaping filter have been presented to improve the computational and implementation complexity. Pulse shaping filters have been designed and implemented by using Raised cosine filter, Nyquist filter and optimized half band filters for software defined radio (SDR) based wireless applications. The performance of differe...

Audio compression is designed to reduce the transmission bandwidth requirement of digital audio streams and storage size of audio files. Audio compression has become one of the basic technologies of the multimedia age to achieve transparent coding of audio and speech signals at the lowest possible data rates. This paper presents a comparative analysis of audio signal compression using transform...

This paper presents a copyright protection scheme based on discrete cosine transform (DCT) and secret sharing techniques. The proposed scheme first utilizes the features of a host image, obtained by performing the DCT on the host image, to generate a master share. Then, the master share is used together with a binary watermark to create an ownership share by employing the secret sharing techniq...

In this paper we present the results of applying data compression to a three-dimensional object recognition technique based on phase-shift digital holography. Industry-standard lossless data compression algorithms were rst applied. Next, lossy techniques based on subsampling, discrete cosine transformation, and discrete Fourier transformation were examined. We used normalized cross-correlation ...
