This proposed learning system model lets engineers experiment more easily with alternative learning-tool configurations when developing knowledge-based applications.THE GROWING COMPLEXITY OF KNOWLEDGE-BASED applications makes it necessary to use automated or semiautomated techniques during knowledge acquisition. Knowledge engineering can also involve using various machine-learning systems, accepting different concept description languages or working with a variety of learning techniques that manage varied inputs such as example sets or background knowledge.For a specific task, knowledge engineers thus might need to experiment with different learning algorithms and their variations. In this context, they must 1. select a machine-learning tool suited to the task, 2. set the parameters that control the tool's behavior, and 3. run the tool, analyze the results, and stop or return to steps 1 or 2.Running this loop might often be difficult and tedious. Selecting the appropriate tool might take time, and finding parameter settings well-suited to the problem's characteristics might also be time-consuming and difficult. Systems that provide a family of learning algorithms in a unified, rather than a single environment, can lessen this loop's complexity and duration.
