Nowadays image recognition technology is widely used, and plays a very important in various fields. Deep learning technology uses multilayer structure to analyze and deal with image features, which can improve the performance of image recognition. the popular models of deep learning contain Auto Encoder, Restricted Boltzmann machine(RBM), Deep Belief Network(DBN), Convolutional Neural Network(CNN), Recurrent Neural Network(RNN) and other improved methods. the applications of image recognition based on deep learning technology including image classification, facial recognition, image search, object detection, pedestrian detection, video analysis. We believe that in the future deep learning will develop rapidly in theory, algorithm, and application and they will make our lives more intelligent.

Advances in the medical imaging technology has lead to a growth in the number of digital images that needs to be classified, stored and retrieved properly. Content Based Image Retrieval (CBIR) systems represent the application of specific computer vision techniques to retrieve images from large databases based on their visual features, such as color, texture and shape. Practically, the use of these visual features only does not offer appropriate measurement performance and accuracy since those features cannot express the high-level semantics of users. therefore, image classification systems based on machinelearning techniques are used as solutions for this problem of CBIR systems. In our previous works, performance of different feature types were investigated by using two techniques of machinelearning which are k-Nearest Neighbor (k-NN) and Support Vector machine (SVM). In this paper, we extend that work by exploring the effect of combining these two classifiers. Our experiments show accuracy improvements based on using ImageCLEF2005 dataset.

Wireless Wireless network finds application in military environments, emergency, rescue operations and medical monitoring due to its self-configuring nature. As the availability of resources such as processing power, buffer capacity and energy are limited in wireless networks;it is required to devise efficient algorithms for packet forwarding. Due to the dynamic nature of the wireless environment, the traditional packet forwarding strategies cannot guarantee good network performance every time. this paper proposes a method for learning data flow rates in wireless network to improve quality of service in the network. Each node in the network learns the environment using reinforcement learning approach and selects appropriate neighbours for packet forwarding. In order to improve the learning capacity of nodes, the hierarchical docition technique is employed. Docition applied to each layer of network, which selects a set of special nodes which has more information about the environment and share this information with less informative nodes. the algorithm is tested in a geographical routing protocol and the results indicate improved network performance.

In the world of communication, security is a big concern. Most of our crucial data is stored in a computer system and in most cases we exchange it over a network. But it's not just our data transmitting over the network but different types of attacks too. these attacks can harm our stored data. Monitoring computer system and its logs (administration logs, security logs, system logs, network logs) and protecting our crucial data is necessary. For these necessities we use intrusion detection system. An intrusion detection system is an applicationthat provides protection from malicious activities or policy violations and generates various rules to defend computer security. Intrusion detection system can be designed and developed on any platform but for its better functionality we are using data mining technique. In past years, many techniques have been introduced to improvise the detection rate. Earlier, in the initial stages of its designing, hardware had to be installed to detect and monitor the system. But, withthe help of data mining it has become easier to work with software and algorithm development. In the recent trends, many new algorithms have been introduced to increase its efficiency. they are categorized under machinelearning algorithms: supervised, unsupervised and hybrid. though hybrid has not yet been categorized finely but various authors have used it by merging different machinelearning algorithms. machinelearning algorithms provide a process of detecting intrusion and generating rules for its detection and prevention. Rule generation is defined by association rule mining and apriori algorithm. An intrusion detection system is not a new application but developing a prototype which will work for the saved logs (administration logs, security logs and system logs) and monitor network logs on host system as well as on client system, so that the Intrusion detection system can alert the user on regular basis, is. In this paper we are using a hybrid mach

We propose a local search approach for learning dynamic systems from time-series data, using networks of differential equations as the underlying model. We evaluate the performance of our approach for two scenarios: first, by comparing with an l1-regularization approach under the assumption of a uniformly weighted network for identifying systems of masses and springs;and then on the task of learning gene regulatory networks, where we compare it withthe best performers in the DREAM4 challenge using the original dataset for that challenge. Our method consistently improves on the performance of the other methods considered in both scenarios.

this paper proposes a med-long term runoff forecasting model based on the principal component analysis (PCA) and the improved BP Neural Network. PCA was utilized to eliminate the relevance between input data, reducing input dimension and effectively reducing the model's structural complexity, improving the model's learning efficiency and forecast performance. the proposed model was predicted and verified with actual data, compared and analyzed withthe traditional BP neural network model. the results show that the proposed model is superior to the traditional BP neural network model in terms of forecasting efficiency and accuracy.
