1. Learning time-varying interaction networks
Abstract : Most biological systems consist of several subcomponents whichinteract with each other. These interactions govern the overall behaviourof the system; and in turn vary over time and in response to internaland external stress during the course of an experiment. READ MORE

2. Efficient Information Visualization of Multivariate and Time-Varying Data
Abstract : Data can be found everywhere, for example in the form of price, size, weight and colour of all products sold by a company, or as time series of daily observations of temperature, precipitation, wind and visibility from thousands of stations. Due to their size and complexity it is intrinsically hard to form a global overview and understanding of them. READ MORE

4. Distributed Optimization in Time-Varying Environments
Abstract : Solving optimization problems in a distributed manner is critical in many systems. Many relevant systems are distributed in nature in the sense that they consist of autonomous agents that are to come to a joint decision based on a certain metric. READ MORE

5. Identification of Time Varying Systems and Application of System Identification to Signal Processing
Abstract : Part IA new approach to identification of time varying systems is presented, and evaluated using computer simulations. The new approach is built upon the similarities between recursive least squares identification and Kalman filtering. READ MORE
