Detailed Description

The basic interface of a lambda function.

A lambda function is used to calculate the answers for our problem. It's the model we've computed.

Note

The output of basic_lambda_f and interpreter can be similar or distinct, depending on the task (regression, classification...) E.g. for regression problems basic_lambda_f and interpreter are identical: they calculate the same number. basic_lambda_f always calculates a meaningful value for the end-user (the class of an example, an approximation...) while interpreter can output a value that is just a building block for basic_lambda_f (e.g. classification tasks with discriminant functions). The typical use chain is: evaluator –[uses]--> basic_lambda_f –[uses]--> interpreter.
