A Fuzzy Commitment Scheme
- ACM CCS'99
, 1999
"... We combine well-known techniques from the areas of errorcorrecting codes and cryptography to achieve a new type of cryptographic primitive that we refer to as a fuzzy commitment scheme. Like a conventional cryptographic commitment scheme, our fuzzy commitment scheme is both concealing and binding: i ..."

Generalization in Reinforcement Learning: Safely Approximating the Value Function
- Advances in Neural Information Processing Systems 7
, 1995
"... To appear in: G. Tesauro, D. S. Touretzky and T. K. Leen, eds., Advances in Neural Information Processing Systems 7, MIT Press, Cambridge MA, 1995. A straightforward approach to the curse of dimensionality in reinforcement learning and dynamic programming is to replace the lookup table with a genera ..."

generalizing function approximator such as a neural net. Although this has been successful in the domain of backgammon, there is no guarantee of convergence. In this paper, we show that the combination of dynamic programming and function approximation is not robust, and in even very benign cases, may produce
Semantic Texton Forests for Image Categorization and Segmentation
"... We propose semantic texton forests, efficient and powerful new low-level features. These are ensembles of decision trees that act directly on image pixels, and therefore do not need the expensive computation of filter-bank responses or local descriptors. They are extremely fast to both train and tes ..."

Learning policies for partially observable environments: Scaling up
, 1995
"... Partially observable Markov decision processes (pomdp's) model decision problems in which an agent tries to maximize its reward in the face of limited and/or noisy sensor feedback. While the study of pomdp's is motivated by a need to address realistic problems, existing techniques for fin ..."

for a selection of extremely small pomdp's taken from the learning literature. In contrast, we show that none are able to solve a slightly larger and noisier problem based on robot navigation. We find that a combination of two novel approaches performs well on these problems and suggest methods

Threatened egotism, narcissism, selfesteem, and direct and displaced aggression: Does self-love or self-hate lead to violence
- Journal of Personality and Social Psychology
, 1998
"... It has been widely asserted that low self-esteem causes violence, but laboratory evidence is lacking, and some contrary observations have characterized aggressors as having favorable self-opinions. In 2 studies, both simple self-esteem and narcissism were measured, and then individual participants w ..."

were given an opportunity to aggress against someone who had insulted them or praised them or against an innocent third person. Self-esteem proved irrelevant to aggression. The combination of narcissism and insult led to exceptionally high levels of aggression toward the source of the insult. Neither
Inconsistency Handling in Multi-Perspective Specifications
- IEEE TRANSACTIONS ON SOFTWARE ENGINEERING
, 1994
"... The development of most large and complex systems necessarily involves many people - each with their own perspectives on the system defined by their knowledge, responsibilities, and commitments. To address this we have advocated distributed development of specifications from multiple perspectives. ..."

. Indeed since the real-world forces us to work with inconsistencies, we should formalise some of the usually informal or extra-logical ways of responding to them. This is not necessarily done by eradicating inconsistencies but rather by supplying logical rules specifying how we should act on them
Classification of Kleinian groups
, 1974
"... We present here a complete classification of those Kleinian groups which have an invariant region of discontinuity and which, in their action on hyperbolic 3-space, have a finite-sided fundamental polyhedron. This classification is complete in the same sense that finitely-generated Fuchsian groups o ..."

The proofs of the theorems are based on the combination theorems [12], the planarity theorem [13], Bers' technique of variation of parameters using quasi-conformal mappings [4], and Marden
Tolerating Memory Latency through Software-Controlled Pre-Execution in Simultaneous Multithreading Processors
- In Proceedings of the 28th Annual International Symposium on Computer Architecture
, 2001
"... Hardly predictable data addresses in many irregular applications have rendered prefetching ineffective. In many cases, the only accurate way to predict these addresses is to directly execute the code that generates them. As multithreaded architectures become increasingly popular, one attractive appr ..."

approach is to use idle threads on these machines to perform pre-execution---essentially a combined act of speculative address generation and prefetching--- to accelerate the main thread. In this paper, we propose such a pre-execution technique for simultaneous multithreading (SMT) processors. By using
A Formal Characterisation of Institutionalised Power
, 1996
"... It is a standard feature of norm-governed institutions that designated agents are empowered to create particular kinds of states of affairs by means of the performance of specified types of actions. Frequently, the states of affairs are of a normative kind, in the sense that they pertain to rights a ..."
