Summary: This paper introduces a new Bayesian framework for generating probabilities of occupancy grids without assuming statistical independence between grid cells' occupancy states, achieving analytical tractability through the use of binary asymmetric channel models. Results demonstrate that the proposed framework outperforms the classical formulation in identifying occupancy grids with lower false alarm and miss detection rates, requiring fewer observations to accurately estimate occupancy probabilities.

Summary: In this article, the problem of ill-conditioning in the Wiener filter is addressed. Four approximate Wiener filter formulas are developed using a truncation technique based on the principal components of a composite covariance matrix. These approximate filters do not directly involve the inverse of the observation covariance matrix, ensuring their reliability and stability. An asymptotic analysis is also presented to show that the approximate filter formulas converge to the Wiener filter as certain approximating terms vanish. Real data is used to evaluate the performance and computation time of the filters, showing that the approximate filters have stable performance with less computation even when the covariance matrix is ill-conditioned.

Summary: This paper addresses an autonomous exploration problem in which a mobile sensor uses an information-theoretic navigation cost function to efficiently detect and classify objects of interest in an unseen search area. The proposed cost function consists of two information gain terms and a novel closed-form representation derived from the definition of mutual information. Experimental results show that using the proposed cost function can improve search efficiency compared to other methods.
