  Parallel Computing Pioneer -- Leslie G. Valiant
Leslie G. Valiant has conducted groundbreaking research in parallel computation from the time he first became involved in the field.
Valiant was educated at King's College, Cambridge; Imperial College, London; and Warwick University, where he received his Ph.D. in computer science in 1974.
Valiant is an active member of the high-performance computing community.

CS201 Summary #1 Leslie Valiant, Harvard University Cognitive Computation UCLA CSD Distinguished Lecture 3/20/97 This Distinguished Lecture was presented by Leslie Valiant, well known for a number of fundamental contributions in theoretical computer science including the BSP model of parallel computation and PAC learning theory.
Valiant's architecture is composed of a network of circuit units and image units.
Valiant intends for circuit units to handle the routine, reflexive behavior, while image units handle knowledge-intensive, complex behaviors (i.e., anything that can't be handled by circuit units).

 CSAIL Event Calendar
Leslie Valiant has proposed a representation of neural concepts which relies on sparse m out of n codes in a randomly, but weakly connected network of cells with high fan-in and high fan-out(*).
In this talk I will discuss a proto-idea in which a similar representation is used to build logic circuits which are robust against failures of the nodes, interconnections, and even partitioning of the network.
I speculate on how these ideas could be applied in the construction of inherently reliable hardware through the addition of another level to the engineering hierarchy: changing the representation of logic signals from being associated with activity of single wires to being represented by the collective activity of ensembles of wires.

Valiant's "neuroidal model" attempts to explain the brain's prodigious capability to store and process information by assuming that neurons and neural connections have an internal structure which matters.
Valiant assumes that a cognitive substrate made of a few elementary functions drives the neuroidal net.
When one of these functions is activated by interaction with the environment, a neural circuit is modified, and such a change contributes to successive action in the environment.

 Computational learning theory - Wikipedia, the free encyclopedia
The incompatibility also arises from differing definitions of probability (see frequency probability, Bayesian probability).
Probably approximately correct learning (PAC learning), proposed by Leslie Valiant;
Bayesian inference, arising from work first done by Thomas Bayes.

In reply to a question by Mike Dyer he discussed the different types of which a man's consciousness may play continuity tricks, and how this relates to the way in which awareness might actually be implemented.
SUMMARY: In this talk Leslie G. Valiant discussed the differences between logic-based and learning-based systems, where logic-based systems are those that are driven by analytic reasoning, for example, deductive and inductive expert systems, and learning-based systems are those based on the classification of patterns using examples as input, for example neural networks.
In particular, he pointed out how the early success of the logic-based systems might even lead one to later believe that such systems comprised the whole of computer science.

 Special Topics: The BSP Model for Portable & Efficient Parallel Computing
Third, it should be mathematically tractable to aid in the development and analysis of algorithms.
The Bulk-Synchronous Parallel (BSP) model, proposed by Leslie Valiant, is a promising candidate for the unifying model.
The purpose of this course is to familiarize the student with the theory behind the BSP model and its practical consequences.

DEPARTMENT Seminar - LESLIE G. Leslie G. Valiant
It has been long recognized that cognitive phenomena exhibit both inductive as well as deductive aspects.
This therefore promises a computationally feasible approach to some of the traditional problems of artificial intelligence and seeks to avoid the main sources of brittleness encountered by traditional logic based systems.

Valiant received B.A., 1970, Mathematics, University of Cambridge, D.I.C., 1973, Computer Science, Imperial College, London, Ph.D., 1974, Computer Science, University of Warwick.
His book, Circuits of the Mind (Oxford University Press, 1994, 2000), formulates such a study in a framework suggested by cortical neurons.
Valiant also conducted groundbreaking research in parallel computation from the time he first became involved in the field.
