Performance Analysis of Statistical and Supervised Learning Techniques in Stock Data Mining

Abstract

Nowadays, overwhelming stock data is available, which areonly of use if it is properly examined and mined. In this paper, the last twelve years of ICICI Bank’s stock data have been extensively examined using statistical and supervised learning techniques. This study may be of great interest for those who wish to mine or study the stock data of banks or any financial organization. Different statistical measures have been computed to explore the nature, range, distribution, and deviation of data. The different descriptive statistical measures assist in finding different valuable metrics such as mean, variance, skewness, kurtosis, p-value, a-squared, and 95% confidence mean interval level of ICICI Bank’s stock data. Moreover, daily percentage changes occurring over the last 12 years have also been recorded and examined. Additionally, the intraday stock status has been mined using ten different classifiers. The performance of different classifiers has been evaluated on the basis of various parameters such as accuracy, misclassification rate, precision, recall, specificity, and sensitivity. Based upon different parameters, the predictive results obtained using logistic regression are more acceptable than the outcomes of other classifiers, whereas naïve Bayes, C4.5, random forest, linear discriminant, and cubic support vector machine (SVM) merely act as a random guessing machine. The outstanding performance of logistic regression has been validated using TOPSIS (technique for order preference by similarity to ideal solution) and WSA (weighted sum approach).

A new Semi-Supervised Intuitionistic Fuzzy C-means Clustering

“…In this paper, 10% of the pixels are labeled for the initial class values. Despite the promising results [10]- [12], a major challenge often arises in dealing with unlabelled data in semi-supervised clustering, in the presence of noise and uncertainty. Generally the percentage of unlabelled data is more as compared to labeled data.…”

Robust Automated detection of Nanocarriers’ Toxicity using Microscopic Image Analysis

“…Identifying significant and functionality related features that appropriately characterize the regularities or sequence inherent in biological image data plays an important role in future predictions. Digital image processing makes this task more quick and decisive by means of automatic processing, manipulation and analysis [29].…”

Improving Semi-Supervised Classification using Clustering

“…Training sets are particularly selected based on the availability of knowledge or labeled data set [1][2]. Now days, supervised classification techniques have been extensively used in the field of pattern matching, including medical diagnosis, face recognition, document classification, banking sector and many other application areas [3][4][5]. The performance of these techniques mostly depends on the availability of the labeled data.…”
