Multimodal Convolutional Neural Networks for Matching Image and Sentence

In this paper, we propose multimodal convolutional neural networks (m-CNNs) for matching image and sentence. Our m-CNN provides an end-to-end framework with convolutional architectures to exploit image representation, word composition, and the matching relations between the two modalities. More specifically, it consists of one image CNN encoding the image content, and one matching CNN learning the joint representation of image and sentence. The matching CNN composes words to different semantic fragments and learns the inter-modal relations between image and the composed fragments at different levels, thus fully exploit the matching relations between image and sentence. Experimental results on benchmark databases of bidirectional image and sentence retrieval demonstrate that the proposed m-CNNs can effectively capture the information necessary for image and sentence matching. Specifically, our proposed m-CNNs for bidirectional image and sentence retrieval on Flickr30K and Microsoft COCO databases achieve the state-of-the-art performances.Comment: Accepted by ICCV 201

A brief analysis of introducing curriculum ideological and political elements into "Mapping Practice of Auto Parts"

The article focuses on the new requirements of integrating curriculum ideological and political elements into the professional practice course of "Automotive Parts Mapping Practice", proposes feasible curriculum ideological and political elements, establishes the course teaching concept of ideological and political element integration, and discusses the new teaching mode different from the traditional practice course, striving to integrate professional knowledge education, ideological and political education, and students\u27 practical ability training. The course aims to integrate professional knowledge education, ideological and political education and the cultivation of students\u27 practical skills, and comprehensively promote the construction of the teaching content, curriculum system, teaching methods, teaching means, teaching conditions and teaching staff of Mapping Practice of Auto Parts, so as to lay a solid practical foundation for the revitalization of Chinese automotive industry and the cultivation of China\u27s own manufacturing technology engineers for the first line of automotive production

The Simultaneous Interpolation of Target Radar Cross Section in Both the Spatial and Frequency Domains by Means of Legendre Wavelets Model-Based Parameter Estimation

The understanding of the target radar cross section (RCS) is significant for target identification and for radar designing and optimization. In this paper, a numerical algorithm for calculating target RCS is presented which is based on Legendre wavelet model-based parameter estimation (LW-MBPE). The Padé rational function fitting model applied for MBPE in the frequency domain is enhanced to include spatial dependence on the numerator and denominator coefficients. This allows the function to interpolate target RCS in both the frequency and spatial domains simultaneously. The combination of Legendre wavelets guarantees the convergence of the algorithm. The method is convergent by increasing the sampling frequency and spatial points. Numerical results are provided to demonstrate the validity and applicability of the new technique

Exploring of teaching effect of course “vehicle chassis structure” based on the teaching mode of divided class

University is an important transit station for students to enter social life, undertaking the important mission of personnel training. Nowadays, a series of challenges exists in university education. It is very important to strengthen the teaching effect of cases in the classroom. The course “Vehicle chassis structure” is a compulsory professional course for undergraduate students majoring in automotive engineering. This work has proposed a teaching mode of divided class for the course of “Vehicle chassis structure”. And it can be concluded that the teaching effect can be improved largely via the teaching mode of divided class. The main purpose of this method is to improve students\u27 initiative learning ability and mutual help and cooperation ability
