Abstract(in English) | As we face huge amounts of varied information, data mining, which helps us discover hidden features or rules from voluminous data systematically, has become more important. However, many data in real world are dirty, including noises such as missing values or irrelevant values. The information mined from such noisy data becomes incorrect. In our previous work [1], we assumed a noisy data model which involves two kinds of noise: one is that an item which should be in a transaction erronously disappears, and another that an item which should not be in a transaction erronously appears. We proposed the method to estimate frequent itemsets [2] on the noiseless data, by probabilistic calculation using the noisy one. However, the real world data may include more complex patterns of noises. In this paper, we present a more generalized noisy data model, and discuss association rule mining under the model. |
