Data Streams are instances that arrive at a very rapid rate with changes in underlying conceptual distributions. Many ensemble learning approaches were developed to handle these changes in the dataset, which proved to be better than a single classifier system. In our work, we will discuss the framework of our new approach, Double Weighted Methodology and empirically prove it to be better than the existing single classifier approaches and the online ensemble approaches. Empirical results would prove that our approach is highly competitive, giving good accuracy and speed in handling and identifying drifts in data, irrespective of noise present in the dataset.

In Telemedicine applications, Digital watermarking is a technique to improve the security and authenticity of ECG signals transmitted to the doctor's end through GSM network. Keeping this in mind, the authors of this paper propose a new watermarking technique which embeds patient's identification inside the ECG signals that will enhance the security and authenticity of ECG signals. In this paper ECG signals are watermarked with patient identity using Adaptive Normalization Factor (ANF) and Least Significant Bit (LSB) watermarking technique to avoid confusion between the ECG signals and patient's identity. The entire technique has been found to be useful to a variety of ECG records for all the 12 leads taken from CSE Multi-lead ECG diagnostic record and the maximum 15 character string that is used to implant watermark embodies for patient's recognition. The novelty of the projected watermarking technique is that the implanted watermark can be completely detached from any altered form of actual signal. It has been observed that the projected method gives a marginal quantity of signal distortion (0.018%), which does not have an effect on any vital features of the ECG signals and it also does not cause any changes in the diagnosis.

Microstrip Antenna (MSA) found widespread applications in satellite communications, wireless and microwave systems, direct broadcast systems; due to their reduced cost and compact-planar structure. Differential Evolution (DE) algorithm is a recent evolutionary computing technique. In this paper, we have implemented DE algorithm to optimize the resonant frequencies of the inset line fed rectangular microstrip patch antenna considering their geometrical design parameters like patch length, patch width and the length of the inset fed as an unknown variables. Simulations have been done for different microwave frequencies (3 to 18 GHz) for the optimized antennas.

Association rule mining (ARM) techniques are effective in extracting frequent patterns and hidden associations among data items in various databases. These techniques are widely used for learning behavior, predicting events and making decisions at various levels. The conventional ARM techniques are however limited to databases comprising categorical data only whereas the real-world databases mostly in business and scientific domains have attributes containing quantitative data. Therefore, an improvised methodology called Quantitative Association Rule Mining (QARM) is used that helps discovering hidden associations from the real-world quantitative databases. In this paper, we present an exhaustive discussion on the trends in QARM research and further make a systematic classification of the available techniques into different categories based on the type of computational methods they adopted. We perform a critical analysis of various methods proposed so far and present a theoretical comparative study among them. We also enumerate some of the issues that needs to be addressed in future research.

Cancer is one of the most destructive diseases which if not detected in time, will surely lead to death. About 12 million people will be died due to cancer by 2030 as per the statistics, provided by the World Health Organization (WHO). Thus a big challenge and area of research emerges in front of both the medical practitioner and scientific researcher to fight against cancers. When a patient is suspected for the presence of malignant tumor they are advised for FNAC (Fine Needle Aspiration Cytology) test where specimens of cells can be taken in minimally invasive way with, e.g., tiny needles, with or without syringes. One of the main drawbacks of cytopathological diagnosis is the time required for an expert to visually inspect a specimen under a microscope, in search of malignant or suspicious cells and manually select them for further analysis. The present work tried to device an automated computer-aided diagnostic system specifically to reduce time and provide `second opinion' for pathologists in making diagnosis. A database of 100 FNAC images were taken on which k-fold cross-validation was performed, where k varied, for the diagnosis of malignancy. Initially, elimination of cytoplasm from the images consisting of multiple cells was done by performing saturation threshold segmentation and from the segmented nucleus boundary, meaningful texture and shape describing features are calculated using GLCM and LBP algorithms. The outcome of segmentation followed by feature extraction was tested by using the Logistic classifier which is a machine learning algorithm. The achieved diagnostic accuracy is 86%, when features obtained by combining GLCM and LBP methods, are used for classification.

This paper presents a novel feature selection and fuzzy-neural classification scheme to decode motor imagery signals during driving. To perform this, we would consider the fuzziness involved in sudden left bent, where the driver is supposed to take sudden 90o left turn during acceleration. This requires classification of motor imagery signals during acceleration and steering left control. The fuzzy-recurrent neural network classifier offers better performance using proposed differential evolution-induced feature selection technique, when compared with principal component analysis in such situation and provides the highest classification accuracy of 98.472%. In addition, false classification rate/misclassification rate is also found much higher when using principal component analysis instead of proposed differential evolution-induced feature selection algorithm. The performance of the proposed differential evolution-induced fuzzy recurrent neural network classifier has been compared with a list of standard classifiers including linear support vector machines, k-nearest neighbor and support vector machines with radial basis function kernel, where fuzzy-recurrent neural network classifier outperforms its competitors with an average classification accuracy of 95.472% and 95.647 for steering left and acceleration motor intensions respectively.

Multi document summarization is a process to produce a single summary from a set of related documents collected from heterogeneous sources. Since the documents may contain redundant information, the performance of a multi document summarization system heavily depends on the sentence similarity measure used for removing redundant sentences from the summary. For graph based multi document summarization where existence of an edge between a pair of sentences is determined based on how much two sentences are similar to each other, the sentence similarity measure also plays an important role. This paper presents an enhanced method for computing sentence similarity aiming for improving multidocument summarization performance. Experiments using two different datasets show the effectiveness of the proposed sentence similarity measure in improving the performance of a graph based multidocument summarization system.

Capacity is one of the significant factors in determining the performance of any cellular system. However, the capacity is limited by the interference. In cellular systems, the major source of interference is the Co-Channel Interference(CCI). In this paper, an analytical method is proposed to evaluate the erlang capacity of 3G WCDMA systems under CCI and the performance analysis with the use of adaptive antenna system. In this the probability of CCI is considered for capacity determination. Erlang Capacity results are evaluated using MATLABR2013b software with different number of co-channel interferes, adaptive antenna system and power control. The capacity of a WCDMA system can be improved with the use of adaptive antenna for a given probability of CCI. It is observed that the capacity of a WCDMA system is increased from 202.82 Erlangs to 278.22 Erlangs per cell with the proposed method.
