This paper explores the role of some basic notions in the study of non-monotonic reasoning, such as validity, logical consequence, context, rules and assumptions.1 It offers some ...
Structured prediction tasks pose a fundamental trade-off between the need for model complexity to increase predictive power and the limited computational resources for inference i...
Writing concurrent programs is difficult because of the complexity of ensuring proper synchronization. Conventional lock-based synchronization suffers from wellknown limitations, ...
I describe my experiences as an artist in making large digital portraits along with some of the issues that make this process more exciting, and cumbersome, than picking up a penc...
This paper describes a drawing system that incorporates two novel interaction techniques based on analogies to physical tools. Power tools add limited autonomy in the form of rota...
