The invention is a computer implemented technique for id entifying anomalous data in a data set. The method uses cascaded k-Means clustering and the ID3 decision tree learning methods to characterize a training data set having data points with known characterization. The k-Means clustering method first partitions the training instances into k clusters using Euclidean distance similarity. On each training cluster, representing a density region of normal or anomaly instances, the invention builds an ID3 decision tree. The decision tree on each cluster refines the decision boundaries by learning the sub-groups within the cluster. A test data point is then subjected to the clustering and decision trees constructed form the training instances. To obtain a final decision on classification, the decisions of the k-Means and ID3 methods are combined using rules: (1) the Nearest-neighbor rule, and (2) the Nearest-consensus rule.

The invention relates to a data privacy protection method in a classification data mining system. All attributes of processing data in the system are allocated to all parties according to a distributed vertical partitioning mode. The method includes that firstly, each party deploys privacy data thereof in random data in a ciphertext form and acquires information entropy of each attribute by cooperative computing; secondly, each party acquires information gain of each attribute by adopting an encrypted transfer mode for computation results in the computation process; thirdly, the information gains of all the attributes are compared to acquire the attribute corresponding to the maximum information gain, and division is performed by taking the attribute as a node; finally, whether or not conditions for ending division are satisfied is judged, and if yes, the division is ended, otherwise the scheme is circulated. On the basis of a privacy protection ID3 classification model, a fully homomorphic encryption algorithm is adopted, and private data protection in the network classification data mining process is realized effectively.

The invention relates to Id knockout mammals having a disruption in at least one and at most three alleles of inhibitor of differentiation genes, Id1 and Id3. This results in reduction or prevention of a cell proliferative disorder in the mammal as compared to a wild-type mammal. In particular, tumor growth and/or metastasis is shown to be inhibited. Further, tumor growth is shown to have poor vascularization and extensive necrosis in Id knockout mammals lacking 3 out of 4 of the Id1, Id3 alleles (Id1−/−Id3±). Drug screening methods to select agents useful to affect activity or expression of Id1 or Id3 gene products are disclosed. Therapeutic methods employing selected agents in subjects in need of treatment and diagnostic methods and test kits to identify subjects having, or at risk of having, a neurological or cell proliferative disorder are also described.
