DESCRIPTION:Speakers: BARLETTA\, Luca ()\nDescription: A classical problem
in synchronization\, an activity that plays a central role in signal
processing for digital communication\, is that of extracting the phase of
a sinusoid affected by phase noise and embedded in additive noise. In the
talk\, the problem is presented as an instance of Bayesian inference. Four
variants of the basic problem are treated.\n1) Sinusoid with constant
amplitude\, where the phase is extracted by filtering the sinusoid
through the Wiener filter.\n2) Sinusoid affected by known amplitude
modulation. Here the system model is no more stationary\, and the phase
should be extracted by filtering the sinusoid through the Kalman filter.
\n3) Sinusoid affected by unknown amplitude modulation. Here non-
parametric methods\, such as quantization of the phase space\, should be
adopted. \n4) A message is transmitted through a channel that includes
up/down conversion\, that is multiplication of the message by a sinusoid.
In this context\, the phase noise affecting the sinusoid is a source of
disturbance that compromises channel capacity. Computation of channel
capacity can be approached by Bayesian methods that track the phase noise
that affect the sinusoid.\nURL: http://events.ego-

DESCRIPTION:Speakers: MAGARINI\, Maurizio ()\nDescription: Given a hidden
state process with memory and a measurement process that is memoryless
given the state\, one has to make inference on the hidden state sequence
given the measurement sequence. This activity can be performed by the so-
called Bayesian tracking\, where the probability of the state at time k is
recursively computed from the probability of the state at time k-1 and
from the measurement at time k. The talk will recall the basics of
Bayesian tracking: two-step recursion based on predict-update\, forward-
backward recursion for making inference on the state at time k given the
entire measurement sequence. The Kalman filter is then presented as an
instance of Bayesian tracking for a non-stationary linear state
transition model and Gaussian processes. Wiener filter is then derived for
the stationary case. The general case of non-linear and non-Gaussian
model can be difficult to deal with. To get good results\, the approach to
be adopted should fit the specific state transition and measurement model
at hand. As examples\, the talk will present the non-Gaussian parametric
approach\, the state-space discretization approach\, and the sequential
importance sampling approach based on particle filters.\nURL:

DESCRIPTION:Speakers: Dr. CHINCARINI\, Andrea (INFN)\nDescription: In the
framework of neurodegenerative diseases\, and in particular the
Alzheimer's disease (AD)\, we are witnessing an increasing presence of
neuroimaging data\, magnetic resonant images (MRI) and positron emission
tomography (PET) above all.\nDespite the fact that clinical scanners have
been around for some decades\, MRI and PET images have only recently
become a dependable support in diagnosing early and prodromal AD.\nThe
purpose of image analysis is to find supporting evidence to help in early
clinical assessment. In the case of neurodegenration leading to AD\, we
would ideally look for a measure (marker) able to discriminate between
normalcy versus pathology at a pre-clinical stage\, easy to implement in
clinical practice and possibly based on quick\, low- cost\, and widely
available procedures. In addition\, a “good” marker should have
predictive value as to whether a subject with current unknown or unclear
clinical assessment will or will not develop the pathological condition in
a given timeframe.\nFrom a data analysis point of view\, the problem can
be restated as a measure of a “signal” (the pathology marker) on a
“background” of normalcy. Whether a marker can have predictive value
at all implies that it must be sensitive to some key aspects of the
pathology process well before their effects have a clear clinical
counterpart.\nWe shall give an overview of some relevant branches in brain
image analysis and the requirements to define a suitable signal over the
confounding variability (noises) peculiar to life-science studies.\nURL:

SUMMARY:Coherent Target Detection in Heavy-Tailed Compound-Gaussian

DESCRIPTION:Speakers: Prof. GINI\, Fulvio ()\nDescription: Coherent radar
target detection is the subject of the second part of the talk. In high
resolution radar systems the disturbance cannot be modelled as Gaussian
distributed and the classical detectors suffer from high losses. Then\,
according to the adopted disturbance model\, optimum and sub-optimum
detectors are derived and their performance analyzed against a non-
Gaussian background. First\, the problem of detecting completely known and
fluctuating random signals\, possibly with unknown parameters\, against
correlated non-Gaussian clutter modelled as a compound-Gaussian process is
then described exploiting different degrees of knowledge on target and
clutter statistical characteristics. A generalized likelihood ratio test
(GLRT) detector and a fully adaptive constant false alarm rate (CFAR)
detector are derived and different novel interpretations of the detection
algorithms provided in order to highlight the relationships and the
differences among them and the links with the Gaussian clutter case. Each
interpretation suggested different ways to implement the optimum detector
and allowed to derive sub-optimum detectors easier to implement than the
optimum and with very low losses. \n Modern radar systems generally
operate in non-homogeneous and non-stationary clutter environment. In this
condition the amplitude statistics and the power spectral density of the
disturbance are unknown. Therefore\, the adaptive versions of the
algorithms previously described\, which estimate the clutter covariance
matrix\, are then introduced. An estimation algorithm is described which
guarantees the CFAR property and its performance are investigated and
compared to that of the maximum likelihood (ML) estimator. The important
cases of target signal partially unknown or modelled as a subspace random
process are also analyzed. The proposed detectors are tested against both
simulated data and measured high resolution sea clutter data to
investigate the dependence of their performance on the various clutter and
signal parameters.\nURL: http://events.ego-

DESCRIPTION:Speakers: Dr. GRECO\, Maria Sabrina ()\nDescription: The first
part of the talk focuses on the statistical analysis and modeling of radar
clutter echoes. This is a central issue for the design and performance
evaluation of radar systems. Main goal of this talk is to describe the
state-of-the-art approaches to the modeling and understanding of land and
sea clutter echoes and their implications on performance prediction and
signal processors design. \nThe talk will first introduce radar sea and
ground clutter phenomena\, measurements and measurement limitations\, at
high and low resolution\, high and low grazing angles with some references
to classical model for Radar Cross Section prediction. Then the main part
of the talk will be dedicated to modern statistical and spectral models
for high resolution sea and ground clutter and\, particularly\, to the
methods of experimental validation using recorded data sets. A plethora of
experimental results will be shown and commented.\nURL: http://events
