This paper aims to take general tensors as inputs for supervised learning. A supervised tensor learning (STL) framework is established for convex optimization based learning techniques such as support vector machines (SVM) and minimax probability machines (MPM). Within the STL framework, many conventional learning machines can be generalized to take n/sup th/-order tensors as inputs. We also study the applications of tensors to learning machine design and feature extraction by linear discriminant analysis (LDA). Our method for tensor based feature extraction is named the tenor rank-one discriminant analysis (TR1DA). These generalized algorithms have several advantages: 1) reduce the curse of dimension problem in machine learning and data mining; 2) avoid the failure to converge; and 3) achieve better separation between the different categories of samples. As an example, we generalize MPM to its STL version, which is named the tensor MPM (TMPM). TMPM learns a series of tensor projections iteratively. It is then evaluated against the original MPM. Our experiments on a binary classification problem show that TMPM significantly outperforms the original MPM.

This paper describes the robust reading competitions for ICDAR 2003. With the rapid growth in research over the last few years on recognizing text in natural scenes, there is an urgent need to establish some common benchmark datasets and gain a clear understanding of the current state of the art. We use the term 'robust reading' to refer to text images that are beyond the capabilities of current commercial OCR packages. We chose to break down the robust reading problem into three subproblems and run competitions for each stage, and also a competition for the best overall system. The subproblems we chose were text locating, character recognition and word recognition. By breaking down the problem in this way, we hoped to gain a better understanding of the state of the art in each of the subproblems. Furthermore, our methodology involved storing detailed results of applying each algorithm to each image in the datasets, allowing researchers to study in depth the strengths and weaknesses of each algorithm. The text-locating contest was the only one to have any entries. We give a brief description of each entry and present the results of this contest, showing cases where the leading entries succeed and fail. We also describe an algorithm for combining the outputs of the individual text locators and show how the combination scheme improves on any of the individual systems. © Springer-Verlag 2005.

The business opportunities in after-sales services such as condition based maintenance were noticed by many vendors of process and automation equipment before adequate standards and architectures became available. Consequently, at a client's premises there are many units of process equipment, software modules and Internet connections that have been installed by different vendors, and this uncoordinated work has created serious interoperability, maintainability and security problems. This paper proposes an open standards-based service architecture for industrial telematics that supports interoperability, software component lifecycle management and secure execution and communication of components in a multi-vendor environment. © 2004 IEEE.

An approach to modeling cooperative control systems and their operation in process automation is presented in this paper. In this approach agent-oriented software engineering techniques are used throughout the design of cooperative control systems both as modeling method and as implementation technology. A part of a process automation system is modeled as a multi-agent society, which adhere to goal-oriented behavior both in their internal and cooperative operations. Another idea in the approach is to use qualitative process modeling in planning of control operations. The approach outlines a generic process automation agent system, which can be applied to building cooperative control applications. Sequential and supervisory control are presented as example applications. The approach is illustrated with examples from a prototype control system build for a laboratory test process

Content based image retrieval is an active research area of pattern recognition. A new method of extracting global texture energy descriptors is proposed and it is combined with features describing the color aspect of texture, suitable for image retrieval. The same features are also used for image classification, by its semantic content. An exemplar fuzzy system for aerial image retrieval and classification is proposed. The fuzzy system calculates the degree that a class, such as sea, clouds, desert, forests and plantations, participates in the input image. Target applications include remote sensing, computer vision, forestry, fishery, agricultures, oceanography and weather forecasting. © Springer-Verlag Berlin Heidelberg 2004.
