Abstract: We consider the problem of online linear regression on arbitrary deterministic sequences when the ambient dimension d can be much larger than the number of time rounds T.

Linear regression is a statistical technique used to observe trends, determine correlation, and predict future observations. Therefore, we usually use this equation to define linear regression: Where the function . In order to evaluate the predication a metric system needs to be developed and this is done by comparing the ypredicted value as in equation 2 with the yreal value of that particular record. In essence, regression is not necessarily accurate for non-linear cases. The underlying principle of this technique is called the least-squared, which is the process of The first few in this list are Multiple R and R Square, which are measures of fit i.e. This tremendous amount of data is waiting to be analysed but can't be analysed with one single computer anymore. Linear regression gives the false impression that the fit will always be a linear function, which is true, but only in the relationship between the input data and the output data. Wheelan provides a very interesting limitation for regression. Big data is a hot topic nowadays and the pile of data gets bigger and bigger. How well the regression model can explain the independent variable given all the dependent variables and observations. We introduce the notion of sparsity regret bound, which is a deterministic online counterpart of recent risk bounds derived in the stochastic setting In a second part we apply a parameter-free version of this algorithm to the stochastic setting (regression model with random design). Building linear regression with MapReduce on Hadoop. I have introduced linear regression, polynomial regression and principal component analysis, but this is only the tip of the iceberg.
