On greedy randomized block Kaczmarz method for consistent linear systems
, 2021The randomized block Kaczmarz method aims to solve linear system A x = b by iteratively projecting the current estimate to the solution space of a subset of the constraints.

In this paper we discuss incomplete data sets with missing attribute values interpreted as “do not care” conditions. For data mining, we use two types of probabilistic approximations, global and saturated. Such approximations are constructed from two types of granules, characteristic sets and maximal consistent blocks. We present results of experiments

We discuss two interpretations of missing attribute values, lost values and “do not care” conditions. Both interpretations may be used for data mining based on characteristic sets. On the other hand, maximal consistent blocks were originally defined for incomplete data sets with “do not care” conditions, using only lower and upper approximations.

Complexity of Rule Sets Induced by Characteristic Sets and Generalized Maximal Consistent Blocks
2018We study mining incomplete data sets with two interpretations of missing attribute values, lost values and “do not care” conditions. For data mining we use characteristic sets and generalized maximal consistent blocks. Additionally, we use three types of probabilistic approximations, lower, middle and upper, so altogether we apply six approaches to ...

This paper deals with adaptive radar detection of targets in the presence of Gaussian disturbance sharing a block-diagonal covariance structure. The problem is formulated according to a very general signal model, which contains the point-like, range ...
