Where Do Relations Come From?
Relational knowledge is a hallmark of human cognition and the subject of a vast body of research. In this paper we argue that existing accounts of relations are inadequate because they have little to say about how relations arise in the rst place and because they tend to be limited to particular sorts of relational tasks. We present a new approach to the learning and representation of relations...
متن کاملWhere do perseverations come from?
RB, a patient with probable Alzheimer's disease, makes continuous perseverations of single letters when writing (e.g. fruit-->fruuit), particularly on high frequency letters.

No continuous perseverations were found in oral production, in...

Theoretically, it provides a concrete evolutionary psychological theory of son-daughter preference: why pe...
متن کاملWhere Do Features Come From?
It is possible to learn multiple layers of non-linear features by backpropagating error derivatives through a feedforward neural network. This is a very effective learning procedure when there is a huge amount of labeled training data, but for many learning tasks very few labeled examples are available. In an effort to overcome the need for labeled data, several different generative models were...
متن کاملWhere do preferences come from?
Rational choice theory analyzes how an agent can rationally act, given his or her preferences, but says little about where those preferences come from. Preferences are usually assumed to be xed and exogenously given. Building on related work on reasons and rational choice (Dietrich and List forthcoming), we describe a framework for conceptualizing preference formation and preference change. In...
