jildt.tilde
Class languageBias

java.lang.Object
  jason.asSemantics.DefaultInternalAction
      jildt.tilde.languageBias

All Implemented Interfaces:

jason.asSemantics.InternalAction, java.io.Serializable

public class languageBias
extends jason.asSemantics.DefaultInternalAction

Internal action to generate the learning language bias after the examples in Exs. The language bias is the definition of which literals are going to be considered as candidates to be included in the Logical Decision Tree. A jildt_rm directive indicates that its argument should be considered as a candidate to refine a query tree. It is important to emphasize that this internal action only returns the language bias, but it does not add automatically the beliefs to knowledge base of the agent.

Use:
jildt.tilde.languageBias(Exs, Lb).

Parameters:

• + examples (List): a list of examples where the language bias will be generated from.
• + language bias (List): a list of literals that form the learning language bias.

Examples: Given the training examples below.

1. jildt_example(put_label, [intend(put(b,c)), on(a,table),on(z,c),on(b,a),on(c,table),clear(table)], fail)).
2. jildt_example(put_label, [intend(put(b,c)), on(a,c),on(z,table),on(b,table),on(c,table),clear(table)], success)).

• jildt.tilde.languageBias([1, 2], Lb): Lb unifies with the list [jildt_rm(clear("+")), jildt_rm(clear("-")), jildt_rm(on("+","-")), jildt_rm(on("-","+")), jildt_rm(on("+","+")), jildt_rm(on("-","-"))].
• jildt.tilde.languageBias([1, 2], Lb, X): Throws an exception due to only two arguments are needed for executing the internal action.
• jildt.tilde.languageBias(1, Lb): Throws an exception because the first argument must be a list.
• jildt.tilde.languageBias([1, 2], clear("+")): Throws an exception because the second argument must be variable.
