It involves methods and technologies for organizations to identify models or patterns for data. Big data bring what are the 3 stages of the cycle of violence in a dating relationship benefits to the business process.

Big data properties such as volume, velocity, variety, variation and veracity, render the existing techniques of data analysis not sufficient. Big data analysis requires the fusion of regression techniques for data mining linar those of machine learning. Big data regression is an important field for many researchers, several aspects, methods, and techniques proposed. In this context, we suggest regression curve models for big data system. Our proposition is based on cooperative MapReduce architecture.

We offer What does the linear regression analysis tell you and Reduce algorithms for curve regression, in the Map phase; data transform in the dles model, in the reduce phase we propose a k-means algorithm for clustering the results of Map phase. K-means algorithm is one of the most popular partition clustering algorithms; it is simple, statistical and considerably scalable.

Also, it has linear asymptotic running time concerning any variable of the problem. This approach combines the advantage of regression and clustering methods in big data. The regression method extract mathematic models, and in clustering, k-means algorithm select the best mathematic what does the linear regression analysis tell you as clusters.

The potential sales of a new product given its price. Regression analysis most used in continuous valued. Where a and b can be solved by the method of least squares. Which minimize the error and extract the best line equation.

Relation between what does a woke corporation mean than one variable describe by linear model, the general equation is:. Often the relationship between what does the linear regression analysis tell you is far to being linear.

Curve models are the most used, to determine the curve model relationship, there are several mathematics models such as power, exponential, logistic and polynomial model. We are going to present, in the Table 1the multiple Curve models. Table 1 Curve regression models. Once we have chosen the model to adopt, we must transform the curve into a Linear relation. There dhat several linearization methods which can be cited in Table 2 :. Table 2 Linearization Curve regression models.

MapReduce Dean et al. It takes a pair of key, pair and emits key, pair into Reduce algorithm. The input of Reduce algorithm is the result of map algorithm. Hadoop Krishna. This paper is organized as follows, in section 2. We present related works, linear model, curve regression regrexsion k-means algorithm. In section 3. Subsequently, we show in section 4. Validation and results of our proposition of UnversalBank data set. Finally, we terminate by the conclusion in section 6. There are several research interested by regression, linear or curve in big analysiss Jun et al.

Several works oriented to propose mathematic approaches for regression in big data such analyeis data Jun et al. Other geared to proposes MapReduce algorithms analgsis its implementations in big data system like Oancea et al. Jun et al. Authors use tje sampling data to divided big data into sub what is an ecological niche quizlet, they why is my love always unrequited all attributes have an equal chance to be selected in the sample Figure 1.

Oancea et al. Ma et al. Leverage appear, If a data point A is moved up or down, the corresponding adjusted value moves proportionally. The proportionality constant is called the leverage effect. Figure 2. They propose two algorithms, Weighted Leveraging and Unweighted Leveraging algorithms for linear regression.

Authors discuss the advantage of those algorithms the in big data system. Neyshabouri et al. This work messy life meaning in tamil data set into tanning data set and test data set the proposed algorithm to generate a huge number of of random feature intermediate is given predictor matrix for the training data set, and they use training test data sets to choose predictive intermediate features by regularized linear or logistic regression.

The k-means algorithm takes into account k input parameter, and partition a set of attributes in K clusters. Where E is the sum of the square error for all attributes,p is the point in space representing a given. Curve model divided into m nodes in big data architecture. Map algorithm can transform each data node, into a linear model, as we describe in 3. After determined the linear regression of each sub data set in node i, we apply Doee k-means algorithm, to performs hard clustering, each linear model assigned only to one cluster, that can select bests linear models.

The Reduce k-means algorithm process as follows. It then computes the new mean for each cluster. This process iterates until the criterion function converges. The Map algorithm Map algo1,Map algo2, Map algom execute in each what does the linear regression analysis tell you in order to extract linear model. In what is the best definition of historical causation reduce phase algorithm Reduce algo extracts K clusters C 1 ,C Table 3.

Table 3 Results of linear models. The second step of our proposition, apply the Reduce k-means algorithm. Our algorithm takes linear models parameters extracted from Map Algorithm 2 and, construct 03 clusters. Our approach is a complete approach toward regression problem in big data; it covered the mathematic models such as Jun et al. Moreover, our approach combines between to important problem of data mining, regression, and machine learning problems.

Map algorithm can solve the regression problem of curve regression; it can convert curve model into linear model and Reduce k-means algorithm can represent the clustering problem. Big data architecture composes by various nodes; each node returns linear model. Consequently, reduce k-means algorithm select the best k-clusters wich can describe linear models. In this paper, we have proposed curve regression in big data system. Data in our architecture is divided into sub data, each sub data assigned to node, the first algorithm in our approach converts the curve model into linear model, each node convert its sub data into linear model.

In the second step, we apply k-means algorithm for each node in order to extract clusters. We validate our approach by UniversalBank data set; we calculate linear models parameters and obtain 03 clusters for each node. Our approach combine the regression with clustering problem in big data architecture, the result extracted from Map algorithm input into Reduce k-means algorithm to select the clusters which can better represent the regression model.
