Relational database systems supports five built-in aggregate functions such as count(), sum(), avg(), max() and min(). These aggregate functions can be used as basic measures in the descriptive mining of multidimensional information. There are two descriptive statistical measures such as measures of central tendency and measures of data dispersion can be used effectively in high multidimensional databases.Measures of central tendency − Measures of central tendency such as mean, median, mode, and mid-range.Mean − The arithmetic average is evaluated simply by inserting together all values and splitting them by the number of values. It uses data from every single value. Let ... Read More
Unsupervised learning is when it can provide a set of unlabelled data, which it is required to analyze and find patterns inside. The examples are dimension reduction and clustering. The training is supported to the machine with the group of data that has not been labeled, classified, or categorized, and the algorithm required to facilitate on that data without some supervision. The objective of unsupervised learning is to restructure the input record into new features or a set of objects with same patterns.Cluster analysis is used to form groups or clusters of the same records depending on various measures made ...

Some persons are utilizing machine learning in their normal life. Consider that it is engaging with the web, defining our preferences, likes, and dislikes through our searches. Some things are chosen up by cookies appearing on our device; from this, the behavior of a customer is computed. It supports to grow the progress of a user through the web and support same suggestions.The navigation system can be treated as one of the instances where it is using machine learning to compute a distance among two places using optimization techniques. Surely, persons are going to use with machine learning briefly.Machine learning ... Read More
Machine learning is an application of Artificial Intelligence that supports an architecture with the capability to learn and enhance from experience without being definitely programmed automatically.It can be used by search engines including Google and Bing to rank internet pages or to determine which advertisement to display to which user. It can be used by social networks including Facebook and Instagram to make a custom feed for each user or to tag the customer by the images that was uploaded.The classification of machine learning is as follows −Supervised Learning − Supervised learning is a type of machine learning method in ...

There are various applications of machine learning which are as follows −Social media services − Machine learning is an essential role in personalizing news feed to superior advertisement focusing over social media. Facebook needs machine learning to display news feed to the user based on its interests by treating items clicked earlier by that user.Facebook always takes note of the friends that it can linked with, the profiles that it can visit, interests, workplace, and on the basis of this continuous learning, a file of Facebook users are suggested for us to become friends with.The Face Recognition nature of Facebook ...

It is a statistical approach for preprocessing data to filter out irrelevant attributes or rank the relevant attribute. Measures of attribute relevance analysis can be used to recognize irrelevant attributes that can be unauthorized from the concept description process. The incorporation of this preprocessing step into class characterization or comparison is defined as an analytical characterization.Data discrimination makes discrimination rules which are a comparison of the general features of objects between two classes defined as the target class and the contrasting class.It is a comparison of the general characteristics of targeting class data objects with the general characteristics of objects ...

Class discrimination is defined as classism. It is prejudice or discrimination based on social class. It involves individual attitudes, behaviors, systems of policies, and practices that are set up to benefit the upper class at the amount as the lower class.Classism can define personal prejudice against lower classes and institutional classism, just as the term racism can define either strictly to personal prejudice or institutional racism. The latter has been represented as how conscious or unconscious classism is clear in the several institutions of our society".Class discrimination can be viewed in several forms of media including television shows, films, and ...

Data generalization summarizes data by replacing relatively low-level values (including numeric value for attribute age) with high-level concepts (including young, middle-aged, and senior). Therefore, it is a process that abstracts a huge set of task-relevant information in a database from a relatively low conceptual level to higher conceptual levels.Following are the two approaches for the efficient and flexible generalization of large data sets −OLAP approach − The data cube technology can be treated as a data warehouse-based, pre-computation-oriented, materialized view approach. It implements offline aggregation earlier an OLAP or data mining query is moved for processing.Attribute-oriented induction approach − It ... Read More
Agglomerative clustering is a bottom-up clustering method where clusters have subclusters, which in turn have sub-clusters, etc. It can start by placing each object in its cluster and then mix these atomic clusters into higher and higher clusters until all the objects are in an individual cluster or until it needs definite termination condition. Some hierarchical clustering methods used to this type. The distinct only in their description of between-cluster similarity.For example, a method called AGNES (Agglomerative Nesting), need the single-link techniques and operates as follows. Consider there are group of objects placed in a rectangle. Initially, every object is ... Read More
