Finally, we introduce association-based classification, which classifies documents based on a set of associated, frequently occurring text patterns. Notice that very frequent terms are likely poor discriminators. Thus only those terms that are not very frequent and that have good discrimi[r]
In this chapter, we introduce the concepts of frequent patterns, associations, and cor- relations, and study how they can be mined efficiently. The topic of frequent pattern mining is indeed rich. This chapter is dedicated to methods of frequent itemset mining. We del[r]
In Kleinberg’s terminology, a page that links to many authorities is a hub; a page that is linked to by many hubs is an authority. These ideas are illustrated in Figure 10.7 The two concepts can be used together to tell the difference between authority and mere popularity. At first glance[r]

Forecasting techniques can be categorized in two broad categories: quantitative and qualitative. The techniques in the quantitative category include mathematical models such as moving average, straight-line projection, exponential smoothing, regression, trend-line analysis, simulation, life-cycle[r]

Decision trees require less data preparation than many other techniques because they are equally adept at handling continuous and categorical vari ables. Categorical variables, which pose problems for neural networks and sta tistical techniques, are split[r]
