19 INTRODUCTION<br />

Machine Learning [Carbonell et <strong>al</strong>., 1983; 1986; Kodratoff & Carbonell, 19901 ís a field of<br />

Artifíci<strong>al</strong> Intellig<strong>en</strong>ce whích has tak<strong>en</strong> impulse in the last years. Among the dífer<strong>en</strong>t types of<br />

Machine Learning techniques, those based on observatíon and discovery are the best<br />

mo<strong>de</strong>lízers for the human behavíor.<br />

From this point of view, ít is interestíng to study the ways in which an autonomous system<br />

[Fritz, 1984; Frítz et <strong>al</strong>., 1989; García Martínez, 19901 can buíld automatic<strong>al</strong>ly theories whích “<br />

mo<strong>de</strong>lices íts <strong>en</strong>virom<strong>en</strong>t. This theoríes can be used by the system to improve its behavior<br />

in response to changes ín íts <strong>en</strong>vírom<strong>en</strong>t.<br />

Theory formatíon by heuristic mutatíon of observartíons [García Martínez, 1992; 1993a;<br />

1993c) have be<strong>en</strong> proposed as a type of Machine Learning techníque based onobservatíon’<br />

and active experím<strong>en</strong>tation for autonomous íntellig<strong>en</strong>t systems [García, Martínez, 1993b;<br />

1993d].<br />

In this paper is proposed the integrated architecture of a system that with elem<strong>en</strong>t<strong>al</strong><br />

Wmpon<strong>en</strong>ts shows an autonomous intellig<strong>en</strong>t behavíor. The pres<strong>en</strong>ted archítecture iS’<br />

is: what are,the consequ<strong>en</strong>ces of applyíng <strong>de</strong>termíned actíons to the <strong>en</strong>vironm<strong>en</strong>t) <strong>de</strong>parting of<br />

no previous knowledge. To accelerate the converg<strong>en</strong>ce of the leatned mo<strong>de</strong>l ís proposed<br />

the utílízation of heurístics and to handle the contradictíons among the g<strong>en</strong>erated theories íS<br />

proposed the utilízation of estimators of probabilíty distributíon.<br />

Consi<strong>de</strong>ratíons are accomplished on the problem of building theories; the limits of the<br />

problem are <strong>de</strong>fíned; a method of building theoríes based on the application of heuristic of’<br />
