Previously Broido and Claffy analysed the global Internet interdomain routing system based on BGP policy atoms: equivalence classes of prefixes based on common AS path as observed from a number of topological locations [6] [7]. In this report we define a variant of policy atoms, called declared atoms. Declared atoms constitute an aggregation mechanism complementary to CIDR aggregation. We descr...

A Low power discrete time sigma delta ADC consisting of a second order sigma delta modulator and third order Cascaded Integrated Comb (CIC) filter is proposed. The second order modulator is designed to work at a signal band of 20K Hz at an oversampling ratio of 64 with a sampling frequency of 2.56 MHz. It achieves a signal to noise ratio of 85.2dB and a resolution of 14 bits. The CIC digital fi...

In this paper, we study how to automatically exploit visual concepts in a text-based image retrieval task. First, we use Forest of Fuzzy Decision Trees (FFDTs) to automatically annotate images with visual concepts. Second, using optionally WordNet, we match visual concepts and textual query. Finally, we filter the textbased image retrieval result list using the FFDTs. This study is performed in...

Word embedding algorithms like word2vec (Mikolov et al., 2013) have enabled advances in topic modelling by training shallow neural networks on the co-occurrence of words in corpuses of sentences. However, it is not clear how this process reflects human cognition. This poster will compare the results of document classification using the word2vec skipgram model and the 20k sensorimotor word norms...

In this paper we report progress made at LIMSI in speaker-independent large vocabulary speech dictation using newspaper speech corpora. The recognizer makes use of continuous density HMM with Gaussian mixture for acoustic modeling and n-gram statistics estimated on the newspaper texts for language modeling. Acoustic modeling uses cepstrum-based features, contextdependent phone models (intra and...

We present an efficient multigrid algorithm that is adequate to solve a heavy linear system given in cloth simulation. Although multigrid has been successfully applied to the Poisson problems, it is hard to migrate to complicated cloth deformations due to its lack of physical meaning in level construction. We addresses this problem by developing a physically faithful technique ensuring the cons...

We present an improved method of compactly organizing the decoding network for a semi-dynamic network decoder. In the previous work [1], the network management units called subnetworks were made compact by self-structuring themselves. We improve this subnetwork representation in two aspects by employing the shared-tail topology [2]. Firstly, we localize the decoding algorithm so that it works w...

A phonetic tied-mixture (PTM) model for efficient large vocabulary continuous speech recognition is presented. It is synthesized from context-independent phone models with 64 mixture components per state by assigning different mixture weights according to the shared states of triphones. Mixtures are then re-estimated for optimization. The model achieves a word error rate of 7.0% at 20k-word dic...

Julius is a high-performance, two-pass LVCSR decoder for researchers and developers. Based on word 3-gram and context-dependent HMM, it can perform almost realtime decoding on most current PCs in 20k word dictation task. Major search techniques are fully incorporated such as tree lexicon, N-gram factoring, cross-word context dependency handling, enveloped beam search, Gaussian pruning, Gaussian...

Extracts of frozen human pituitary glands contain, in addition to normal growth hormone (hGH (Mr = 22,005), a variant of lower molecular weight (approximately 20,000) (Singh, R. N. P., Seavey, B. K. and Lewis, U. J. (1974) Endocrinol. Res. Commun. 1, 449-464). This material, designated 20K hGH, occurs in various forms with the majority present as a heterologous dimer of Mr = 20,000 hGH and hGH....
