Retrieving information from subordination
We show that if (Xs, s ≥ 0) is a right-continuous process, Yt = ∫ t 0 dsXs its integral process and τ = (τl, l ≥ 0) a subordinator, then the time-changed process (Yτl , l ≥ 0) allows to retrieve the information about (Xτl , l ≥ 0) when τ is stable, but not when τ is a gamma subordinator. This question has been motivated by a striking identity in law involving the Bessel clock taken at an indepe...
متن کاملA Method for Retrieving Images from Noisy Incomplete Data
We propose here a nev method for retrieving an image from noisy, incomplete data. It is based on an idea incorporating the principle of maximum entropy, a veil known powerful method for image processing. An image is built on the computer by allocating grains to pixels one at a time on the basis of certain deterministic rules as to where each successive grain is placed in image space. The perfor...
متن کاملMutual Information in a Linear Noisy Network
A feedforward neural network of a given architecture provides a cod ing of its input data In this work we consider a one layer linear network and we are interested in the network con gurations i e the structure of the synaptic couplings which are able to resolve as many features as possible of the input data distribution under noisy conditions Finding such optimal codings can be useful for both...
متن کاملRetrieving information from a hierarchical plan.
Plans give structure to behavior by specifying whether and when different tasks must be performed. However, the structure of behavior need not mirror the structure of the plan. To investigate this idea, the authors studied how plan information is retrieved in the context of a novel sequence-position cuing procedure, wherein subjects memorize two task sequences, then perform trials on which they...
متن کاملA Network of Oscillators for Retrieving Phase Information
We propose a network of oscillators to retrieve given patterns in which the oscillators keep a fixed phase relationship with one another. In this description, the phase and the amplitude of the oscillators can be regarded as the timing and the strength of the neuronal spikes, respectively. Using the amplitudes for encoding, we enable the network to realize not only oscillatory states but also n...
