D - Clutter: Building object model library from unsupervised segmentation of cluttered scenes
Autonomous systems which learn and utilize a limited visual vocabulary have wide spread applications. Enabling such systems to segment a set of cluttered scenes into objects is ...

Combining Experiments to Discover Linear Cyclic Models with Latent Variables
We present an algorithm to infer causal relations between a set of measured variables on the basis of experiments on these variables. The algorithm assumes that the causal relatio...

A Multi-Set Extended Relational Algebra - A Formal Approach to a Practical Issue
The relational data model is based on sets of tuples, i.e. it does not allow duplicate tuples in a relation. Many database languages and systems do require multi-set place, the hi...

Systematic Refinement of Performance Models for Concurrent Component-based Systems
Model-driven performance prediction methods require detailed design models to evaluate the performance of software systems during early development stages. However, the complexity...

A First-Order Isomorphism Theorem
We show that for most complexity classes of interest, all sets complete under rstorder projections (fops) are isomorphic under rst-order isomorphisms. That is, a very restricted v...
