Feature compression is one of the most importmant steps in pattern recognition. In this paper, based on minimum squared error (MSE) rule, we first give discrete K-L transform (DKLT). According to idea of entropy function, we propose two new entropy functions-entropy density function (EDF) and representation entropy (RE), by which we can metricize information content of data matrix X. Secondly, an optimization feature compression is put forward and information compression degree is measured by feature compression rate (FCR) and accumulated feature compression rate (AFCR) proposed by authors firstly. In the end, we give an adaptive feedforward neural network (FNN) and improved adaptive FNN to realize optimization feature compression This method can be applied in Biology, Biomathematics, Ecology, and Bioinformation Science and so on for optimization feature compression. keywords: keywords: pattern recognition, optimization feature compression, entropy density function (EDF), representation entropy (RE), feedforward neural network (FNN). © Springer-Verlag Berlin/Heidelberg 2006.

The fault detection of the anode effect is of great significance in the process of aluminum electrolysis. Effective prediction of the anode effect can increase the output of the electrolytic cell and reduce the power consumption. In this paper, data is extracted from the real-time production process of aluminum electrolysis. In order to remove the redundancy and noise in the data and save the time cost of manual selection of features, the principal component analysis method is used to optimize other algorithms, and then compare with LightGBM. It has been proved by experiments that the LightGBM model not only improves the prediction accuracy of the anode effect to 99.9%, but also advances the fault prediction time to 40 minutes, which has high practical application value. © 2019 IEEE.

This paper presents an improved deep reinforcement learning (DRL) algorithm, namely Advanced Actor Critic (AAC), which is based on Actor Critic (AC) algorithm, to the video game Artificial intelligence (AI) training. The advantage distribution estimator, Normal Constraint (NC) function and exploration based on confidence are introduced to improve the AC algorithm, in order to achieve accurate value estimate, select continuous spatial action correctly, and explorate effectively. The aim is to improve the performance of conventional AC algorithm in a complex environment. A case study of video game StarCraft II mini-game AI training is employed. The results verify that the improved algorithm effectively improves the performance in terms of the convergence rate, maximum reward, average reward in every 100 episode, and time to reach a specific reward, etc. The analysis on how these modifications improve the performance is also given through interpretation of the feature layers in the mini-games. © Springer Nature Singapore Pte Ltd. 2020.

Sonochemistry is one of the important mechanisms of microbial inactivation by ultrasound. In this study, the molecular mechanism of Escherichia coli O157: H7 response to sonochemistry was comprehensively investigated by transcriptomics and lipidomics. The results showed that 1494 genes and 130 lipids were significantly changed after sonochemical treatment. Sonochemistry could interfere with the expression of genes related to osmotic stress response, betaine and glutamate synthesis, mechanosensitive ion channels, and K+ transfer systems to increase cell membrane permeability. Moreover, sonochemistry induced cell envelope remodeling, modulated the expression of genes related to phospholipid metabolism, glyceride metabolism, fatty acid synthesis and degradation, and led to differential changes in the content of key lipids (e.g., phosphatidylethanolamine, phosphatidic acid, cardiolipin, and triacylglycerol). The regulation of virulence factors was manifested by inhibiting exotoxin synthesis and activating the type III secretion system. This investigation reveals the molecular mechanism of inactivation from the perspective of sonochemistry and provides a theoretical basis for the application of ultrasound to inactivate pathogens. © 2025, The Authors.

Box 2704 Beijing100080 China

This paper describes the ICT Statistical Machine Translation systems that used in the evaluation campaign of the International Workshop on Spoken Language Translation (IWSLT) 2009. For this year's evaluation, we participated in the Challenge Task (Chinese-English and English-Chinese) and BTEC Task (Chinese-English). And we mainly focus on one new method to improve single system's translation quality. Specifically, we developed a sentence-similarity based development set selection technique. For each task, we finally submitted the single system who got the maximum BLEU scores on the selected development set. The four single translation systems are based on different techniques: a linguistically syntax-based system, two formally syntax-based systems and a phrase-based system. Typically, we didn't use any rescoring or system combination techniques in this year's evaluation. © IWSLT 2009. All Rights Reserved.

Computational music emotion recognition is to recognize the emotional content in music tracks. In computational music emotion recognition studies, researchers have paid close attention to the audio content of the music tracks. Although lyrics content and music context contribute greatly to the perceived emotion, these kinds of emotional information are usually ignored. Based on this finding, we propose a multimodal music emotion recognition method jointly predicting the valence and arousal values by combining the audio, lyrics, track name, and artist of a given track. Audio features, lyrics features and context features are extracted separately and fused by a cross-modal attention mechanism, forming a hierarchical structure. Our proposed model outperforms two baselines by a large margin and achieves state-of-the-art performance on two public datasets. © 2022 IEEE.

A millimeter-wave dielectric cylindrical Luneburg Lens antenna is proposed, which is comprised of multiple concentric dielectric shells of the same thickness. The dielectric-constant distribution of the cylinder is controlled by the volume fraction of air between dielectric shells. The measured gain of the proposed antenna varies from 9.86 to 11.80 dBi from 30 GHz to 40 GHz. A low side-lobe level of -18.35 dB is obtained from measured radiation patterns at 35 GHz. © 2023 IEEE.

Sounds, especially music, contain various harmonic components scattered in the frequency dimension. It is difficult for normal convolutional neural networks to ob-serve these overtones. This paper introduces a multiple rates dilated causal convolution (MRDC-Conv) method to capture the harmonic structure in logarithmic scale spectrograms efficiently. The harmonic is helpful for pitch estimation, which is important for many sound processing applications. We propose HarmoF0, a fully convolutional network, to evaluate the MRDC-Conv and other dilated convolutions in pitch estimation. The re-sults show that this model outperforms the DeepF0, yields state-of-the-art performance in three datasets, and simultaneously reduces more than 90% parameters. We also find that it has stronger noise resistance and fewer octave errors. © 2022 IEEE.
