A method of detecting an intrusion in the operation of a computer system based on a plurality of events. A rule set is determined for a training set of data comprising a set of features having associated costs. For each of a plurality of events, the set of features is computed and a class is predicted for the features with a rule of the rule set. For each event predicted as an intrusion, a response cost and a damage cost are determined, wherein the damage cost is determined based on such factors as the technique of the intrusion, the criticality of the component of the computer system subject to the intrusion, and a measure of progress of the intrusion. If the damage cost is greater than or equal to the response cost, a response to the event.

The present invention relates to the use of computerized intelligent agents to facilitate the integration of networked performance of financial transactions with computerized methods of financial accounting. Incorporated into this combined financial transaction/financial accounting system are intelligent agents that automatically analyze the system information to provide users with financial advice. This invention permits the automated performance on-line of a wide variety of financial transactions and integrates these transactions with computerized financial accounting. All of this information is collated and analyzed automatically by intelligent agents, which generate user-specific financial reports, profiles, and advice, and under appropriate conditions take action.

In a method of generating an anomaly detection model for classifying activities of a computer system, using a training set of data corresponding to activity on the computer system, the training set comprising a plurality of instances of data having features, and wherein each feature in said plurality of features has a plurality of values. For a selected feature and a selected value of the selected feature, a quantity is determined which corresponds to the relative sparsity of such value. The quantity may correspond to the difference between the number occurrences of the selected value and the number of occurrences of the most frequently occurring value. These instances are classified as anomaly and added to the training set of normal data to generate a rule set or other detection model.

Techniques for classifying structural data with skewed distribution are disclosed. By way of example, a method classifying structural input data comprises a computer system performing the following steps. Multiple classifiers are constructed, wherein each classifier is constructed on a subset of training data, using one or more selected composite features from the subset of training data. A consensus among the multiple classifiers is computed in accordance with a voting scheme such that at least a portion of the structural input data is assigned to a particular class in accordance with the computed consensus. Such techniques for structured data classification are capable of handling skewed class distribution and partial feature coverage issues.

A commodity product distribution plan is used to instruct source sites as to how commodity products are to be distributed among target sites. Where the commodity products are to be sold at auction, a wide range of auction prices can be expected due to mixed models, model years, commodity attributes such as color or optional features, economic conditions, and the auction site location itself. Additional factors that contribute to realized auction prices include depreciation and interest rate costs as well as constraints on shipments and auction site capacities. The present invention provides forecast auction prices for the commodity products, taking these various factors into consideration. In this way, an optimized distribution planned aimed at maximizing the potential profit for the commodity products to be sold at auction is generated.
