Fig. 1. The CBR cycle, from [6]

any differences between the old and new houses to see if price adjustments are
in order. If the new house has one more bathroom than the old house, the price
could be adjusted upwards. If the new house is in a less desirable school district,
or has a smaller garage, the price could be adjusted downwards. Professional
real estate agents have knowledge of the value added or subtracted by various
features, and their adjustment mechanisms can be encoded for use in the Reuse
phase of the CBR cycle. Once the price is adjusted accordingly, the agent has
a solution, or a fair selling price for the house. Of course, if the house does not
sell for this price, further adjustment may be needed during the Revise phase.
Once the house is sold, the new case can be stored in the case base, along with
its actual selling price, during the Retain phase. This last phase enables the
system to grow and to learn by acquiring additional experiences that may be
retrieved and reused in the future.
