Toward a Computational Theory of Early Visual Processing In Reading
(1980-09-01)
This paper is the first of a series aimed at developing a theory of early visual processing in reading. We suggest that there has been a close parallel in the development of theories of reading and theories of vision ...
Representation and Recognition of the Movement of Shapes
(1980-10-01)
The problems posed by the representation and recognition of the movements of 3-D shapes are analyzed. A representation is proposed for the movements of shapes that lie within the scope of Marr & Nishihara's (1978) 3-D ...
The Progressive Construction of Mind
(1980-06-01)
We propose a vision of the structure of knowledge and processes of learning based upon the particularity of experience. Highly specific cognitive structures are constructed through activities in limited domains of ...
Primer for R users
(1980-09-01)
R is a text formatter. The information in this primer is meant to explain, in simple English, the basic commands needed to use R. Input for R is prepared on computer systems using a text editor. Which editor employed ...
Design of LISP-based Processors, or SCHEME: A Dielectric LISP, or Finite Memories Considered Harmful, or LAMBDA: The Ultimate Opcode
(1979-03-01)
We present a design for a class of computers whose 'instruction sets' are based on LISP. LISP, like traditional stored-program machine languages and unlike most high-level languages, conceptually stores programs and data ...
Learning and Reasoning by Analogy: The Details
(1979-04-01)
We use analogy when we say something is a Cinderella story and when we learn about resistors by thinking about water pipes. We also use analogy when we learn subjects like Economics, Medicine and Law. This paper ...
A Truth Maintenance System
(1979-06-01)
To choose their actions, reasoning programs must be able to make assumptions and subsequently revise their beliefs when discoveries contradict these assumptions. The Truth Maintenance System (TMS) is a problem solver ...
Director Guide
(1978-06-01)
Director is a programming language designed for dynamic graphics, artificial intelligence, and naﶥ users. It is based upon the actor or object oriented approach to programming and resembles Act 1 and SmallTalk. ...
K-Lines: A Theory of Memory
(1979-06-01)
Most theories of memory suggest that when we learn or memorize something, some "representation" of that something is constructed, stored and later retrieved. This raises questions like: How is information represented? ...
Non-Monotonic Logic I
(1978-08-01)
"Non-monotonic" logical systems are logics in which the introduction of new axioms can invalidate old theorems. Such logics are very important in modeling the beliefs of active processes which, acting in the presence ...
