Statistical ones. The point is that data mining is just a tool in the whole process: It is people who take the results, along with other knowledge, and decide what action to apply. Data mining prompts another question, which is really a political one: To what use are society’s resources being put? We mentioned previously the application of data mining to basket analysis, where supermarket checkout records are analyzed to detect associations among items that people purchase. What use should be made of the resulting information?

All of these effects are incorporated by reconstructing a year’s load as a sequence of typical days, fitting the holidays in their correct position, and denormalizing the load to account for overall growth. Thus far, the load model is a static one, constructed manually from historical data, and implicitly assumes “normal” climatic conditions over the year. The final step was to take weather conditions into account using a technique that locates the previous day most similar to the current circumstances and uses the historical information from that day as a predictor.

The expert studies this information, which is noisy because of limitations in the measurement and recording procedure, to arrive at a diagnosis. Although handcrafted expert system rules had been developed for some  CHAPTER 1 What’s It All About? situations, the elicitation process would have to be repeated several times for different types of machinery; so a learning approach was investigated. Six hundred faults, each comprising a set of measurements along with the expert’s diagnosis, were available, representing 20 years of experience in the field.
