Machine learning algorithm for numerical value estimation

I'm looking for machine learning algorithms that can map a set of parameters to an estimate calculated numerical value. In other words, the problem I'm trying to address does not look for a classification solution; rather it needs to estimate a numerical value based on given parameters. Say I have a training data set where the input parameters are correctly mapped to the corresponding numerical value; I need an algorithm that can learn the estimation function from this training data set and is then be able to predict correct estimation to any newly input parameters.
