Tasks and Functionalities of Data Mining

Data mining functionalities tasks are designed to be semi-automatic or fully automatic and on large data sets to uncover patterns such as groups or clusters, unusual or over the top data called anomaly detection and dependencies such as association and sequential pattern. Once patterns are uncovered, they can be thought of as a summary of the input data, and further analysis may be carried out using Machine Learning and Predictive analytics. For example, the data mining step might help identify multiple groups in the data that a decision support system can use. Note that data collection, preparation, reporting are not part of data mining. There is a lot of confusion between data mining and data analysis.Data mining finds patterns. Mining uses Machine Learning and mathematical and statistical models to identify hidden patterns in data, whereas data analysis analyses suitable statistical models. Two data mining categories:

Descriptive Data Mining:

It includes certain knowledge to understand what is happening within the data without a previous idea. The common data features are highlighted in the data set. For example, count, average etc. Predictive Data Mining: It helps developers to provide unlabeled definitions of attributes. Data mining can anticipate crucial business KPIs using linearity and historical data. For example, predicting the volume of business next quarter based on performance in the previous quarters over several years or judging from the findings of a patient’s medical examinations that is he suffering from any particular disease.

Functionalities of Data Mining

Data mining tasks can be classified into two types: descriptive and predictive. Descriptive mining tasks define the common features of the data in the database, and the predictive mining tasks act in inference on the current information to develop predictions. Data mining is widespread. Predicts and characterises data. But the ultimate objective in Data Mining Functionalities is to observe the various trends in data mining. There are several data mining functionalities that the organized and scientific methods offer, such as:

1. Class/Concept Descriptions

Data or features define a class or idea. Class is a shop floor category, and concept is an abstract idea that categorises data, like clearance sale and non-sale merchandise. There are two data mining functionalities concepts here, one that helps with grouping and the other that helps in differentiating. Data Discrimination: Attribute value differences separate data sets.

2. Mining Frequent Patterns

Data’s most frequent patterns The dataset contains many data mining functions. Milk and sugar are examples of frequent item sets. Frequent substructure: Trees and graphs can be used with item sets or subsequences. Frequent Subsequence: A regular pattern series, such as buying a phone followed by a cover.

3. Association Analysis

It analyses the set of items that generally occur together in a transactional dataset.Retail sales use it as Market Basket Analysis. Two criteria determine association rules: It provides which identifies the common item set in the database. Confidence is the conditional probability that an item occurs when another item occurs in a transaction.

4. Classification

Classification is a data mining technique that categorises data mining functionalities items in a collection based on some predefined properties. It uses methods like if-then, decision trees or neural networks to predict a class or essentially classify a collection of items.A training set of known things trains the system to predict the category of unknown items.

5. Prediction

It defines predict some unavailable data values or spending trends. It can be a prediction of missing numerical values or increase or decrease trends in time-related information. There are primarily two types of predictions in data mining: numeric and class predictions. A historical data-based linear regression model predicts numbers. Prediction of numeric values helps businesses ramp up for a future event that might impact the business positively or negatively.

6. Cluster Analysis

In image processing, pattern recognition and bioinformatics, clustering is a popular data mining functionality. Data attributes represent the classes. Data without class labels are pooled together. Clustering algorithms group data based on similar features and dissimilarities.
7. Outlier Analysis
Outlier analysis is important to understand the quality of data. If there are too many outliers, you cannot trust the data or draw patterns. An outlier analysis determines if there is something out of turn in the data and whether it indicates a situation that a business needs to consider and take measures to mitigate.

8. Evolution and Deviation Analysis

Evolution Analysis examines changing datasets. Analysis models define, categorise, cluster, and distinguish time-related data by capturing evolutionary tendencies.
9. Correlation Analysis
It evaluates two numerically measured continuous variables’ relationship. Researchers can use this type of analysis to see if there are any possible correlations between variables in their study. The term “correlation” refers to a mathematical technique that can be used to determine whether or not two characteristics are related to one another and, if so, to what extent this relationship exists. It performs an analysis on the relationship between two continuous variables whose values are measured numerically. In order for researchers to determine whether or if their study contains any potential correlations between the variables being examined, they can employ this form of analysis.
