Smartphone-based insurance telematics or usage based insurance is a disruptive technology which relies on insurance premiums that reflect the risk profile of the driver; measured via smartphones with appropriate installed software. A survey of smartphone-based insurance telematics is presented, including definitions; Figure-of-Merits (FoMs), describing the(More)

Usage Based Insurance (UBI) programs for car insurance is becoming mainstream using tailored vehicle mounted hardware, where the commercial initiatives can be traced back to the mid-nineties [1]. The smartphone has been identified as an enabler for future UBI, replacing the vehicle (after-) mounted dedicated hardware with a ubiquitous device with a(More)
A novel approach is developed for predicting body trajectories for cancer progression, where conditional probabilities of clinical data are modeled using Hidden Markov Model techniques. Basically, each potential body site is encoded by an N-letter code, and a disease trajectory is described in terms of a string of letters. Patient data base records are then(More)
In this paper we derive novel algorithms for estimation of reg-ularization parameters and for optimization of neural net architectures based on a validation set. Regularization parameters are estimated using an iterative gradient descent scheme. Architecture optimization is performed by approximative combinatorial search among the relevant subsets of an(More)
