    Describes a novel AI technique, called a plausibility network, that allows for learning to filter natural language phrases according to predefined classes under noisy conditions. We describe the automatic knowledge acquisition for representing the words of natural language phrases using significance vectors and the learning of filtering of phrases according to ten different domain classes. We part... View full abstract»

    Compares three methods of estimating the volatility of daily S&P 100 Index stock market options. The implied volatility, calculated via the Black-Scholes model, is currently the most popular method of estimating volatility and is used by traders in the pricing of options. Historical volatility has been used to predict the implied volatility, but the estimates are poor predictors. A neural netw... View full abstract»

    The design and analysis of engine crankshafts involves the use of a myriad of computer aided engineering design and analysis tools. To be successful in reducing cycle time to the finished product, these tools must be integrated into an environment in which common data is shared and the analyst need not be an expert in all areas. Currently, these different analyses are completed independently of ea... View full abstract»

    Ecological studies and multispecies ecotoxicological tests are based on the examination of a variety of physical, chemical and biological data with the intent of finding patterns in their changing relationships over time. The data sets resulting from such studies are often noisy, incomplete, and difficult to envision. We have developed machine learning and visualization software to aid in the anal...

    MeteoAssert, a system developed at the Forecast System Laboratory, analyzes gridded data sets and produces descriptions which are organized sets of assertions representing the content of weather messages. Each assertion conveys a single weather characteristic with a certain spatial and temporal scope. The assertions in a description are linked by discourse relations that predetermine the structure...

    This paper describes the design of a case-based reasoning system for the redesign of local area networks. It introduces a mechanism for solution adaptation based on a hierarchy of possible actions, each of which is associated with background knowledge about its suitability. A novel similarity measure is used to rank actions where multiple alternative actions are found for an action that cannot be ... View full abstract»

    New results related to a novel approach in computer vision are reported in this paper. Rather than designing ever more complex algorithms to extract given objects from images, the design of simple targets for given fast and robust algorithms is promoted. The mathematical nature of this approach leads to optimized target structures. A unifying model for vision algorithms is introduced which combine... View full abstract»

    Describes an intelligent control shell for CAD tools, which can automatically create a command sequence to control CAD systems using symbolic knowledge of general command flows and non-symbolic knowledge of the past execution data. Users define a model of possible control flows, which are transformed into a state transition graph from which executable command sequences are inferred. The control sy... View full abstract»

    The Interactive Discourse Planner (IDP) is designed to describe and justify domain plans interactively. The text plan that IDP incrementally formulates and executes is represented uniformly in the same knowledge base with the domain plans that are under discussion. In this way, the text plan and the domain plans are both accessible for analyzing the user's feedback. IDP can interpret vaguely artic... View full abstract»

    Successful inductive learning requires that training data be expressed in a form where underlying regularities can be recognized by the learning system. Unfortunately, many applications of inductive learning-especially in the domain of molecular biology-have assumed that data are provided in a form already suitable for learning, whether or not such an assumption is actually justified. This paper d... View full abstract»

    Terminological knowledge representation (TKR) systems, such as KL-ONE, are widely used in AI to construct concept taxonomies based on subsumption inferences. However, current TKR systems are unable to represent temporal patterns or recognize instances of such patterns from ongoing observations.

    Workflows are the structured activities that take place in information systems in typical business environments. These activities frequently involve several database systems, user interfaces, and application programs. Traditional database systems do not support workflows to any reasonable extent. Usually, human beings must intervene to ensure their proper execution. We have developed an architectu... View full abstract»

    Studies have shown that software developers tend to use existing human-computer interfaces as examples while designing new interfaces. However, if the examples are poorly designed, or the tasks in the example are inconsistent with the tasks of the new interface, then using examples can be detrimental to the design of the interface. To alleviate the problem of using examples inappropriately, and to... View full abstract»

    An ideal automated reliability analysis system would take a CAD model as input, then identify critical components and output failure probabilities. Unfortunately, the practical systems in use today require a fault tree-a kind of and/or graph-as their input. Since the cognitive distance between the CAD model and its associated fault tree is large, the manual translation step is a source of many mis... View full abstract»
