Mass Spectrometry Imaging (MSI) is a rapidly advancing bioanalyitical approach that enables the simultaneous measurement of thousands of molecular species from intact tissue sections in a spatially resolved manner. It provides the opportunity to develop a fully automated chemical histology approach for accurate tissue classification. Such "machine-learned" tissue identification platforms require efficient and robust extraction of tissue-specific discriminating molecular ion patterns. Here, we present a comparative analysis of several supervised feature extraction methods and propose the use of a Recursive Maximum Margin Criterion (RMMC) method for enhanced extraction of tissue-specific discriminating molecular patterns.

In the literature of face recognition many methods have been proposed which extract local texture features for robust pattern classification. But for final computation of the feature the information about central pixel is not taken into account. In this paper, we propose a novel method which utilizes Local Ternary pattern and Booth's Algorithm techniques to capture the local face features, which utilize central pixel for computation of the feature. Face images are spatially varied and classification works better with local descriptors, a Non-overlapping block wise processing is done on image to limit the features. The Support Vector Machine (SVM) and KNN classifier with proposed similarity measure is used for face classification. Finally, ROC and CMC are plotted for analysis of the system. Experiments are conducted on ORL and faces94 datasets demonstrates that the proposed method has better classification accuracy than previously proposed methods.

Management and recognition of event patterns is becoming thoroughly ingrained in many application areas of Semantically enabled Complex Event Processing (SCEP). However, the reliance of state-of-the-art technologies on relational and rdF triple model without having the notion of time has severe limitations. This restricts the system to employ temporal reasoning at rdF level and use historical events to predict new situations. Additionally, the semantics of traditional query languages makes it quite challenging to implement distributed event processing. In our vision, SCEP needs to consider rdF as a first class citizen and should implement parallel and distributed processing to deal with large amount of data streams. In this paper, we discuss various challenges and limitations of state-of-the-art technologies and propose a possible solution to extend rdF data model for stream processing and pattern matching. Furthermore, we describe a high-level query design that enables efficient parallel and distributed pattern matching through query rewriting.

This paper proposes a method for generating an optimal feature selecting sequence which is cost-effective for pattern classification. The sequence describes the order that feature selects for the process like classification. We model the procedure of feature selecting using Markov decision process (MDP), and use dynamic programming (DP) to learn a strategy to generate the orders only with the feedback of circumstance. To simplify the problem, we design a simple test scene that classifying three objects, whose values of synthetic features are generated randomly, into three classes. The results of experiments show that our method can reduce the computational time of extracting features.

In this paper, a novel violent video detection scheme is presented based on visual views. The violent segment is detected by using motion angle, motion intensity, shot & explosion and blood analysis. In addition, in order to improve the compute efficiency and time savings Hidden Information SVM is used. Experimental result shows that the proposed method is effective in violent video detection.

The problem of bridging the gap between efficient but narrow methods of machine learning, and universal but inefficient methods was considered. Our main claim, which is methodologically important to the field of Artificial General Intelligence (AGI), is that neither narrow nor basic universal methods are sufficient for AGI. This claim was illustrated on example of patternrecognition task using stacked autoencoders and their two extensions with more exhaustive search and richer solution space. These three types of classifiers were evaluated on the base of a criterion that account for both error rate and training time. Depending on the urgency of the task to be solved, less or more universal methods appeared to be better. Thus, AGI might start with narrow methods, but should be able to perform their “universalization” (i.e. extension of the model space possibly up to Turing-complete space if it is appropriate in a certain situation).

patternrecognition problems occur in many domains and consequently well performing classification algorithms are highly sought after. In my talk, I will focus on a particular group of classifiers that generate rule bases consisting of a set of fuzzy if‐then rules. The antecedent part of a rule characterises the input features using fuzzy sets, while the consequent part is established in a learning stage. Starting with a basic fuzzy classifier I will show that, through a simple modification, it can be turned into a cost sensitive classification method, that classification performance can be improved through an error correction learning approach, and that a small yet powerful rule base can be generated through an optimisation approach based on genetic algorithms.
