Bounded-depth threshold circuits for computer-assisted CT image classification
(2001)
We present a stochastic algorithm that computes threshold circuits designed to discriminate between two classes of computed tomography (CT) images. The algorithm employs a partition of training examples into several classes ...
Combining the perception algorithm with logarithmic simulated annealing
(2001)
We present results of computational experiments with an extension of the Perceptron algorithm by a special type of simulated annealing. The simulated annealing procedure employs a logarithmic cooling schedule (-), where ...
Logarithmic simulated annealing for computer-assisted x-ray diagnosis
(2001)
We present a new stochastic learning algorithm and first results of computational experiments on fragments of liver CT images. The algorithm is designed to compute a depth-three threshold circuit, where the first layer is ...
On the convergence of inhomogeneous Markov chains : Approximating equilibrium placements of flexible objects
(2001)
This paper deals with the minimization of local forces in two-dimensional placements of flexible objects within rigid boundaries. The objects are disks of the same size but, in general, of different materials. Potential ...
