An evolutionary algorithm is evolutionary AI-based computer software that solves issues by employing processes that mimic the behaviors of living things. As such, it needs mechanisms that are generally related to biological evolution, including reproduction, mutation, and recombination.An example of data extraction and transformation tools is the ETL-EXTRACT tool suite from evolutionary technologies. Extraction is the service of extracting information from a source system for additional help in a data warehouse environment. It is the first procedure of the ETL process. After the extraction, this data can be changed and loaded into the data warehouse.The process of data extraction contains ... Read More

The human ability to reason from experience based on the ability to identify suitable examples from the prior. A doctor diagnosing infection, a claims analyst flagging fraudulent insurance property, and a mushroom hunter pointing Morels are following a same procedure.Each first recognizes same cases from experience and then uses what their knowledge of those methods to the issues at hand. This is the importance of memory-based reasoning. A database of known data is searched to discover preclassified records same to a new data. These neighbors are used for classification and computation.There are various applications of Memory Based Reasoning which are ... Read More

A neural network is a sequence of algorithms that endeavors to identify basic relationships in a set of data through a process that mimics the method the human brain works. In this approach, neural networks represent systems of neurons, such as organic or artificial.Neural Networks are analytic approaches modeled after the (hypothesized) procedure of learning in the cognitive system and the neurological services of the brain and capable of forecasting new observations (on definite variables) from other observations after executing a process of so-called learning from current information.There are the following steps of Back Propagation which are as follows −The ...

Feed-forward neural networks allows signals to travel one approach only, from input to output. There is no feedback (loops) such as the output of some layer does not influence that same layer. Feed-forward networks tends to be simple networks that associates inputs with outputs. It can be used in pattern recognition. This type of organization is represented as bottom-up or top-down.Each unit in the hidden layer is generally completely connected to some units in the input layer. Because this network includes standard units, the units in the hidden layer compute their output by multiplying the value of each input by ... Read More

C5 is the current version of the decision-tree algorithm that Australian researcher, J. Ross Quinlan has been developing and refining for several years. A prior version, ID3, established in 1986, was influential in the area of machine learning and its successors are used in multiple commercial data mining services.The trees increase by C5 are same to those improves by CART. Like CART, the C5 algorithm first improves an overfit tree and then prunes it back to make a more dynamic model. The pruning method is complex, but C5 does not create use of a validation set to select from between ... Read More

CART is a famous decision tree algorithm first produced by Leo Breiman, Jerome Friedman, Richard Olshen, and Charles Stone in 1984. CART represents Classification and Regression Trees. The CART algorithm improves binary trees and continues divided considering new splits can be found that improves purity.There are some simpler subtrees, each of which defines a different trade-off among model complexity and training group misclassification rate. The CART algorithm recognizes a group of such subtrees as candidate models. These candidate subtrees are used to the validation group and the tree with the minimum validation set misclassification rate is chosen as the last ... Read More

Regression defines a type of supervised machine learning approaches that can be used to forecast any continuous-valued attribute. Regression provides some business organization to explore the target variable and predictor variable associations. It is an essential tool to explore the data that can be used for monetary forecasting and time series modeling.There are various types of regression which are as follows −Linear Regression − Linear regression includes discovering the “best” line to fit two attributes (or variables) therefore that one attribute can be used to predict the other. Multiple linear regression is an advancement of linear regression, where higher than ... Read More

Regression defines a type of supervised machine learning approaches that can be used to forecast any continuous-valued attribute. Regression provides some business organization to explore the target variable and predictor variable associations. It is an essential tool to explore the data that can be used for monetary forecasting and time series modeling.Data can be smoothed by fitting the data to a function, such as with regression. Linear regression includes discovering the “best” line to fit two attributes (or variables) therefore that one attribute can be used to predict the other. Several linear regression is an advancement of linear regression, where ... Read More
