Privacy Preserving For Classification Techniques Essay

1) Privacy Preserving for Classification Techniques It is one of the biggest challenges in data mining. It is a predictive modeling task with the specific aim of predicting the value of a single nominal variable based on the known values of other variables. Classification is the task of generalizing known structure to apply to new data. Classification is a data mining function that assigns items in a collection to target categories or classes. The goal of classification is to accurately predict the target class for each case in the data. A classification task begins with a data set in which the class assignments are known. Classifications are discrete and do not imply order. Continuous, floating-point values would indicate a numerical, rather than a categorical, target. A predictive model with a numerical target uses a regression algorithm, not a classification algorithm. The simplest type of classification problem is binary classification. In binary classification, the target attrib ute has only two possible values: for example, high credit rating or low credit rating. Multiclass targets have more than two values: for example, low, medium, high, or unknown credit rating the model build (training) process, a classification algorithm finds relationships between the values of the predictors and the values of the target. Different classification algorithms use different techniques for finding relationships. These relationships are summarized in a model, which can then beShow MoreRelatedFuture Privacy Of Information Technologies1303 Words   |  6 PagesFuture Privacy of Information Technologies to Protect Personal Data In a modern life, from the minute a person is born, a digital record is created.

Today, the field of privacy has seen rapid advances in recent years because of the increase in the ability to store data. In particular, recent advances in the data mining field have led to increasing concerns about privacy. However, with the development of technologies, the emerging applications result in an accumulationRead MoreThe Time-consuming Task of Preparing a Data Set for Analysis in Data Mining1846 Words   |  7 Pagesmanual efforts are required to build data sets, where a horizontal layout is required. Also many data mining applications deal with privacy for many sensitive data. Therefore we need privacy preserving algorithm for preserving sensitive data in data mining. Horizontal database aggregation is a task that involves many participating entities. However, privacy preserving during such database aggregation is a challenging task. Regular encryption cannot be used in such cases as they do not perform mathematicalRead MoreData Stream Mining : Methods And Challenges930 Words   |  4 Pagesdiscusses various data stream mining technique, current state of the art in streaming algorithms and the challenges. Keywords: Data Stream Mining; Challenges. 1. Introduction Data stream is the continuous flow or stream of data and if it is not processed immediately or stored, then it is lost forever. The arrival of data is so quick that it is not feasible to store it completely in storage, and then perform several queries. That’s why we require some technique or method for processing streams whichRead MorePrivacy Of Data Stream Using Sliding Window Method1790 Words   |  8 Pages Privacy Preserving In Data Stream Using Sliding Window Method 1. INTRODUCTION: Data Mining is defined as extracting information from huge sets of data. In other words, we can say that data mining is the procedure of mining knowledge from data. There is a huge amount of data available in the Information Industry. This data is of no use until it is converted into useful information. It is necessary to analyse this huge amount of data and extract useful information from it. Extraction of informationRead MoreWill You Have An Enterprise Wide System?1153 Words   |  5 Pagesexperiences, opinions, and other relevant information/ Apart from prediction I will also need to do to analyze my customer’s historical behavior.
