In [[data mining]], '''cluster-weighted modeling (CWM)''' is an algorithm-based approach to non-linear prediction of outputs ([[Dependent and independent variables|dependent variables]]) from inputs ([[Dependent and independent variables|independent variables]]) based on [[density estimation]] using a set of models (clusters) that are each notionally appropriate in a sub-region of the input space. The overall approach works in jointly input-output space and an initial version was proposed by [[Neil Gershenfeld]].<ref>Gershenfeld, N.

The procedure for cluster-weighted modeling of an input-output problem can be outlined as follows.<ref name=nature/> In order to construct predicted values for an output variable ''y'' from an input variable ''x'', the modeling and calibration procedure arrives at a [[joint probability distribution|joint probability density function]], ''p''(''y'',''x''). Here the "variables" might be uni-variate, multivariate or time-series. For convenience, any model parameters are not indicated in the notation here and several different treatments of these are possible, including setting them to fixed values as a step in the calibration or treating them using a [[Bayesian analysis]]. The required predicted values are obtained by constructing the [[conditional probability distribution|conditional probability density]] ''p''(''y''|''x'') from which the prediction using the [[conditional expected value]] can be obtained, with the [[conditional variance]] providing an indication of uncertainty.  
 
The important step of the modeling is that ''p''(''y''|''x'') is assumed to take the following form, as a [[mixture model]]:
:<math>p(y,x)=\sum_1^n w_jp_j(y,x), </math>
where ''n'' is the number of clusters and {''w<sub>j</sub>''} are weights that sum to one. The functions ''p<sub>j</sub>''(''y'',''x'') are joint probability density functions that relate to each of the ''n'' clusters. These functions are modeled using a decomposition into a conditional and a [[marginal distribution|marginal density]]:
:<math>p_j(y,x)=p_j(y|x)p_j(x), </math>
where:
:*''p<sub>j</sub>''(''y''|''x'') is a model for predicting ''y'' given ''x'', and given that the input-output pair should be associated with cluster ''j'' on the basis of the value of ''x''. This model might be a [[regression analysis|regression model]] in the simplest cases.
 
:*''p<sub>j</sub>''(''x'') is formally a density for values of ''x'', given that the input-output pair should be associated with cluster ''j''. The relative sizes of these functions between the clusters determines whether a particular value of ''x'' is associated with any given cluster-center. This density might be a [[Gaussian function]] centered at a parameter representing the cluster-center.
 
In the same way as for [[regression analysis]], it will be important to consider preliminary [[data transformation]]s as part of the overall modeling strategy if the core components of the model are to be simple regression models for the cluster-wise condition densities, and [[normal distribution]]s for the cluster-weighting densities ''p<sub>j</sub>''(''x'').
 
==General versions==
The basic CWM algorithm gives a single output cluster for each input cluster. However, CWM can be extended to multiple clusters which are still associated with the same input cluster.<ref name="feldkamp">{{cite journal|last=Feldkamp|first=L.A.|coauthors=Prokhorov, D.V.; Feldkamp, T.M.|date=2001|title=Cluster-weighted modeling with multiclusters|journal=International Joint Conference on Neural Networks|volume=3|issue=1|pages=1710&ndash;1714|url=http://ieeexplore.ieee.org/Xplore/login.jsp?url=/iel5/7474/20319/00938419.pdf?temp=x}}</ref> Each cluster in CWM is localized to a Gaussian input region, and this contains its own trainable local model.<ref name="mit">{{cite journal|last=Boyden|first=Edward S.|title=Tree-based Cluster Weighted Modeling: Towards A Massively Parallel Real-Time Digital Stradivarius|publisher=MIT Media Lab|location=Cambridge, MA|url=http://edboyden.org/violin.pdf}}</ref>  It is recognized as a versatile inference algorithm which provides simplicity, generality, and flexibility; even when a feedforward layered network might be preferred, it is sometimes used as a "second opinion" on the nature of the training problem.<ref name="dearborn"/>
 
The original form proposed by Gershenfeld describes two innovations:
* Enabling CWM to work with continuous streams of data
* Addressing the problem of local minima encountered by the CWM parameter adjustment process<ref name="dearborn">{{cite journal|last=Prokhorov|first=A New Approach to Cluster-Weighted Modeling Danil V.|coauthors=Lee A. Feldkamp, and Timothy M. Feldkamp|title=A New Approach to Cluster-Weighted Modeling|publisher=Ford Research Laboratory|location=Dearborn, MI|url=http://home.comcast.net/~dvp/cwm.pdf}}</ref>
 
CWM can be used to classify media in printer applications, using at least two parameters to generate an output that has a joint dependency on the input parameters.<ref name="media">{{cite journal|last=Gao|first=Jun|coauthors=Ross R.
