Ant robots have very low computational power and limited memory. They communicate by leaving pheromones in the environment. In order to create a cooperative intelligent behavior, ants may need to get together; however, they may not know the locations of other ants. Hence, we focus on an ant variant of the rendezvous problem, in which two ants are to be brought to the same location in finite tim...

In five experiments, we examined cross-language activation during speech production in various groups of bilinguals and trilinguals who differed in nonnative language proficiency, language learning background, and age. In Experiments 1, 2, 3, and 5, German 5- to 8-year-old second language learners of English, German-English bilinguals, German-English-Language X trilinguals, and adult German-Eng...

Bidirectional DC–DC converters are key devices in the DC distribution system and energy storage (ESS). It is important to consider safety of elements converter for rapid conversion power direction. Damages may occur power-related components circuit if direction inductor current or capacitor voltage changes instantaneously. To make flow change smoothly quickly, this research proposed a bidirecti...

In this paper, a new bidirectional neural network for better acoustic-articulatory inversion mapping is proposed. The model is motivated by the parallel structure of human brain, processing information by having forward-inverse connections. In other words, there would be a feedback from articulatory system to the acoustic signals emitted from that organ. Inspired by this mechanism, a new bidire...

In this paper, we present bidirectional Long Short Term Memory (LSTM) networks, and a modified, full gradient version of the LSTM learning algorithm. We evaluate Bidirectional LSTM (BLSTM) and several other network architectures on the benchmark task of framewise phoneme classification, using the TIMIT database. Our main findings are that bidirectional networks outperform unidirectional ones, a...

Three admissible bidirectional search algorithms have been described in the literature: A Cartesian product approach due to Doran, Pohl's BHPA, and Champeaux and Sint's BHFFA2. This paper describes an algorithm, GP, which contains the latter two and others. New admissibility results are obtained. A first order analysis is made comparing the run times of Cartesian produc$ search, two versions of...

In this paper it will be shown how uniication grammars can be used to build a reversible machine translation system. Uniication grammars are often used to deene the relation between strings and meaning representations in a declarative way. Such grammars are sometimes used in a bidirectional way, thus the same grammar is used for both parsing and generation. In this paper I will show how to use ...

Psychophysical representations built by Gabor visual chan-nels described in complex analytic form are shown to be related to thewavelet transform of visual stimuli under empirically plausible bandwidthconstraints. Analysis of the psychophysical wavelet representations ofone-dimensional stimuli eliciting some visual contrast illusions (Machbands and the Craik-Cornsweet-O’Brie...

We present the Potsdam systems that participated in the semantic dependency parsing shared task of SemEval 2014. They are based on linguistically motivated bidirectional transformations between graphs and trees and on utilization of syntactic dependency parsing. They were entered in both the closed track and the open track of the challenge, recording a peak average labeled F1 score of 78.60.
