Abstract: An error bound that indicates how well a hypothesis function approximates an unknown target function over a set of out-of-sample examples is computed from known error bounds for basis functions, as follows. An optimization problem is formed in which basis function error bounds imply constraints on feasible outputs of the target function over out-of-sample inputs. The optimization problem is solved to find an upper bound on the differences between the hypothesis function outputs and feasible target function outputs. This upper bound is a an error bound for the hypothesis function.

In this embodiment, the model can simulate, for example, a heterogeneous group of diabetes related disorders, from insulin resistant to severe diabetic, and can predict the likely effects of therapeutic interventions.

Abstract: Methods and systems for translating models generated in one modeling environment into models that can be used in other modeling environments. In particular, information regarding a relationship between components of models in one modeling environment is translated into corresponding elements of models in other modeling environments.

Abstract: A system and method for optimizing placement of network equipment and information load in a network over a period of time. A demand input structure having a plurality of demands organized by their time points is provided as an input to a model generator and an optimization processor associated therewith. Starting with the earliest demand set to be serviced by the network, a directed graph network model is obtained by using appropriate transformation techniques. A cost function associated with the network model is constructed using a flow cost term and an equipment cost term. Appropriate constraints are imposed on the cost function for optimization. A solution set comprising network placement information and demand routing information is obtained for a current time point. When the next demand set is taken up for optimization, the network model and associated cost function are recursively updated by using the solution set obtained for the demand set at a prior time point.

Abstract: One embodiment of the present invention provides a system that uses interval techniques to solve a multi-objective optimization problem. During operation, the system receives a representation of multiple objective functions (ƒ1, . . . , ƒn) at a computer system, wherein (ƒ1, . . . , ƒn) are scalar functions of a vector x=(x1, . . . , xn). The system also receives a representation of a domain of interest for the multiple objective functions. Next, the system performs an interval optimization process to compute guaranteed bounds on a Pareto front for the objective functions (ƒ1, . . . , fn), wherein for each point on the Pareto front, an improvement in one objective function cannot be made without adversely affecting at least one other objective function. While performing the interval optimization process, the system applies a direct-comparison technique between subdomains of the domain of interest to eliminate subdomains that are certainly dominated by other subdomains.

The present invention may export models created in one modeling environment into the neutral data format. The neutral data format may subsequently be imported into other modeling environments in which new models are generated using the information contained in the neutral data format. The present invention also provides animation of the newly generated models by animation clients via open animation interfaces that support multiple animation clients at a simultaneous time.
