With the hype about Artificial Intelligence, machinelearning has become a trending topic these days. Lots of tools are available for data visualization, yet most of the model training is dependent on scripting languages. Orange datamining tool provides the flexibility with data pre-processing, visualization and model training and test in a single software. The proposed paper applies machinelearning algorithms to a fruit image dataset and perform a comparative study of the algorithms to determine which algorithm has the highest Classification Accuracy and Precision score. Decision making is based on the images used to train the algorithm to learn the specific features derived from those trained images. Cross validation is performed in order to evaluate the results for Classification Accuracy. The difference between actual and predicted values is evaluated to determine the number of instances predicted correctly.

In this paper, a new method for the classification of power quality (PQ) events of the electricity networks based on deep learning approach is presented. In contrast with the existing PQ event data analysis techniques, sampled voltage data of the PQ events are not used, but image files of the three-phase PQ event data are analyzed by taking the advantage of the success of the deep leaning approach on image-file-classification. Therefore, the novelty of the proposed approach is that, image files of the voltage waveforms of the three phases of the power grid are classified. PQ events obtained from four transformer substations of the electricity transmission system for a year are used for training and testing the proposed classification method. DIGITS deep learning platform of NVIDIA is employed for the application of the deep learning algorithm on PQ event data images. It is shown that the test data can be classified with 100% accuracy. The proposed work is believed to serve the needs of the future smart grid applications, which are fast and automatic analysis of the electricity grid and taking automatic countermeasures against potential PQ events.

Clustering, a component of datamining is the process of grouping objects into several clusters such that objects in the same cluster have maximum similarity while the objects in different clusters has maximum dissimilarity. Clustering has been used in diverse fields including Text mining, patternrecognition, Image analysis, Bioinformatics, machinelearning, Voice mining, Image processing, Web cluster engines, Whether report analysis etc. To perform the task of clustering, various datamining tools arc freely available. These tools have their own features and carry out efficiently the task of generating clusters automatically for a given set of data. This paper discusses seven such tools in detail. A comparative study of these tools has been also done on basis of various parameters as License type of the tool, Programming Language used by tool, Interface provided by the tool, Developer of the tool etc. The goal is to provide the users/researchers all the necessary details about these clustering tools so that it may help them to select an appropriate tool for their use in cluster analysis.

Much research has been conducted for developing efficient, automated, interpretable, and highly accurate machinelearning algorithms. However, the primary challenge remains-developing algorithms successful in all of these aspects simultaneously. For applications, where human lives are at stake, having to choose between accuracy and interpretability is not acceptable. To address this challenge, previously the Dominance Classifier and Predictor (DCP) algorithm, capable of discovering of the human-understandable models in simple and visualizable terms was proposed. On the benchmark Wisconsin Breast Cancer (WBC) dataset, it achieved greater accuracy than other interpretable algorithms, reducing the gap between the prediction accuracy of interpretable and non-interpretable algorithms on these data. This paper proposes a new interpretable algorithm RPPR, to bridge this gap more by boosting DCP via discovering properties of misclassified cases. Experiments with RPPR on WBC and two other benchmark datasets using 10-fold cross validation, achieved accuracies greater than 99%. Thus, the accuracy of non-interpretable algorithms is reachable without sacrificing interpretability.

data objects are considered as fundamental keys in learning methods that without the objects the mining algorithms are meaningless. data objects basically direct the accuracy of the selected algorithm in case if they are extracted from inappropriate groups. Knowing the exact type of data object leads the miner to provide a suitable environment for learning algorithms. Supervised and unsupervised learning methods propose some membership functions that perform with respect to behaviour of each data category to classify data objects and solutions. The paper explores different type of data objects by categorizing them based on their behaviour with respect to learning methods. We also introduce some critical objects that play the main role in each data set. Issues on critical objects in mining algorithms are fully discussed in this paper. The accuracy and behaviour of these critical objects are compared by running fuzzy, probabilistic, and possibilistic algorithms on some data sets presented in this paper. The results prove that some methods are able to provide a suitable environment for critical objects and some are not. The comparison results also show that most of the learning methods have difficulties dealing with critical objects. Lack of ability to deal with these objects may cause irreparable consequences.

The visual quality of the video is improved by realizing higher resolution and higher frame rate. In order to realize higher frame rate, we propose new frame rate up-conversion method using spatio-temporal convolutional neural network. In recent years, with the development of machinelearning techniques such as convolutional neural networks, clearer interpolation frame estimation has been realized. However, with the conventional convolutional neural network method, it is difficult to estimate an accurate interpolation frames for video including complex motion. In order to deal with this problem, we adopted spatio-temporal convolution rather than conventional spatial convolution. Spatio-temporal convolution is thought to be effective for nonlinear motion because it can capture the time change of the motion of the object. We verified the effectiveness of the proposed method by using video data including complex motions such as rotational motion and scaling.

The goal of the starting case-study is not only to develop procedures for automatically generating corpora using 3D patternrecognition, but also to reflect on the associated schematizations and how they can be applied in computer science and visual sciences. For this purpose, methods of object mining in 3D data are to be developed. We chose an object group which is defined by its complexity in shape and the similarity between the objects: In 4th and 3rd century BC ancient Greece small terracotta figurines used to be an art form that was quite common. Based on 200 of those terracottas, a classification system will be elaborated with digital methods, which is able to meet the complexity of the artefacts. In close cooperation between computer science and archaeology, this experimental process leads to a fundamental examination of the concept of patternrecognition as a humanities category. The discussion of the various concepts and methods will be carried out in two complementary dissertations.

Clustering is a robust technique in the area of datamining research for extracting useful information from a set of data. It classifies the data into several clusters based on similarity of the pattern. The quality of clustering can be presented based on a metric of dissimilarity of objects, compared for various types of data. This paper presents one of the agglomerative approaches of hierarchical clustering techniques i.e. complete-link clustering by considering Euclidian distance metric for the quality estimation for students' projects data.

This paper presents a method of mining the data obtained by a collection of pressure sensors monitoring a pipe network to obtain information about the location and size of leaks in the network This inverse engineering problem is effected by support vector machines (SVMs) which act as pattern recognisers. In this study the SVMs are trained and tested on data obtained from the EPANET hydraulic modelling system. Performance assessment of the SVM showed that leak size and location are both predicted with a reasonable degree of accuracy. The information obtained from this SVM analysis would be invaluable to water authorities in overcoming the ongoing problem of leak detection.
