We present models for encoding sentences into embedding vectors that specifically target transfer learning to other NLP tasks. The models are efficient and result in accurate performance on diverse transfer tasks. Two variants of the encoding models allow for trade-offs between accuracy and compute resources. For both variants, we investigate and report the relationship between model complexity...

Compression is playing a vital role in data transfer. Hence, Digital camera uses JPEG standard to compress the captured image. Hence, it reduces data storage requirements.Here, we proposed FPGA based JPEG encoder. The processing system is coupled with DCT and then it is quantized and then it is prepared for entropy coding to form a JPEG encoder.

In this work, we present a technique that learns discriminative audio features for Music Information Retrieval (MIR). The novelty of the proposed technique is to design auto-encoders that make use of data structures to learn enhanced sparse data representations. The data structure is borrowed from the Manifold Learning field, that is data are supposed to be sampled from smooth manifolds, which ...

In this paper, an H.264/AVC-based multiple description video coding scheme is proposed. It utilizes the advanced video coding tools and features provided in H.264/ AVC to introduce redundancy into descriptions. Two independently decodable descriptions are generated, each consisting of two slice groups. One of them, called main slice group (MSG), is encoded normally as main information. The othe...

In its most elementary form, compressed sensing studies the design of decoding algorithms to recover a sufficiently sparse vector or code from lower dimensional linear measurement vector. Typically it is assumed that decoder has access encoder matrix, which in combinatorial case and binary. this paper we consider problem designing set codes their measurements alone, without matrix. To end study...

A new class of analog-to-digital (A/D) and digitalto-analog (D/A) converters using a flaky quantiser, called the β-encoder, has been shown to have exponential bit rate accuracy while possessing a self-correction property for fluctuations of the amplifier factor β and the quantiser threshold ν. The probabilistic behavior of such a flaky quantiser is explained as the deterministic dynamics of the...

Nowadays, adaptive modulation and coding (AMC) techniques can facilitate flexible strategies subject to dynamic channel quality. The AMC transceivers select the most suitable coding and modulation mechanisms subject to the acquired channel information. Meanwhile, a control channel or a preamble is usually required to synchronously coordinate such changes between transmitters and receivers. On t...

MPEG-4 which is currently being developed by MPEG (Moving Pictures Experts Group), is poised to become a standard for supporting current and emerging interactive multimedia applications. The objective of MPEG-4 is to support content-based compression, communication, access and manipulation of digital objects which can be natural or synthetic. Since MPEG-4 based video consists of objects and pro...

The paper addresses minimality of encoders for basic convolutional codes over Zpr by using a recently developed concept of row reducedness for polynomial matrices over Zpr . It is known in the literature that the McMillan degree of a basic encoder is an upper bound for the minimum number of trellis states, but a general expression is missing. This open problem is solved in this paper. An expand...

To meet the requirement of distributed video coding (DVC) in resource-limited sensor networks, Wyner-Ziv theorem-based source coding with side information only available at the decoder states that an intraframe encoder with interframe decoder system can achieve comparable coding efficiency of a conventional interframe encoder and interframe decoder system. In this paper, firstly, a block discre...
