Consumer Profile Identification and Allocation
We propose an easy-to-use methodology to allocate one of the groups which
have been previously built from a complete learning data base, to new
individuals. The learning data base contains continuous and categorical
variables for each individual. The groups (clusters) are built by using only
the continuous variables and described with the help of the categorical ones.
For the new individuals, only the categorical variables are available, and it
is necessary to define a model which computes the probabilities to belong to
each of the clusters, by using only the categorical variables. Then this model
provides a decision rule to assign the new individuals and gives an efficient
tool to decision-makers. This tool is shown to be very efficient for customers
allocation in consumer clusters for marketing purposes, for example.Comment: Accepted in the IWANN 07 conference San Sebastian, June 2007
The "profilograph": a toolbox for the analysis and segmentation of gas load curves
Conference WSOM 05 5-8 September 2005International audienceThe paper presents a method to allocate a class of a Kohonen map to a new customer without knowing anything about the variables used for the classification. In this study, a classification of daily gas load profiles is performed on a panel of Gaz de France customers. Then, we use a multinomial logit model to allocate a class to a new customer according to its additional variables. With this model, it is also possible to infer the probability to belong to each of the Kohonen classes. The main application for Gaz de France is the inference of the daily gas load for any customer
