Out-of-distribution detection using normalizing flows on the data manifold
This study investigates the effect of manifold learning using normalizing flows on out-of-distribution detection.
Combination of Single and Multi-frame Image Super-resolution: An Analytical Perspective
Super-resolution is the process of obtaining a high-resolution image from one or more low-resolution images.
Stochastic First-Order Learning for Large-Scale Flexibly Tied Gaussian Mixture Model
Gaussian Mixture Models (GMMs) are one of the most potent parametric density models used extensively in many applications.

In this paper, a method for measuring camera motion and removing its effect is presented that efficiently reduces the camera motion effect on tracking.
Joint Manifold Learning and Density Estimation Using Normalizing Flows
We propose a single-step method for joint manifold learning and density estimation by disentangling the transformed space obtained by normalizing flows to manifold and off-manifold parts.

ParsiNorm: A Persian Toolkit for Speech Processing Normalization
Comparison with other available Persian textual normalization tools indicates the superiority of the proposed method in speech processing.
Solving Viewing Graph Optimization for Simultaneous Position and Rotation Registration
A viewing graph is a set of unknown camera poses, as the vertices, and the observed relative motions, as the edges.
Vector Transport Free Riemannian LBFGS for Optimization on Symmetric Positive Definite Matrix Manifolds
Riemannian LBFGS (RLBFGS) is an extension of this method to Riemannian manifolds.
Optimal Triangulation Method is Not Really Optimal
Therefore, in contrast to the common practice, we argue that the simple mid-point method should be used in structure-from-motion applications where there is uncertainty in camera parameters.
Accurate and fast matrix factorization for low-rank learning
In this paper, we tackle two important problems in low-rank learning, which are partial singular value decomposition and numerical rank estimation of huge matrices.

We propose a free-energy minimization framework for selecting the subspaces and integrate the policy of the state-space into the subspaces.
Contour Integration using Graph-Cut and Non-Classical Receptive Field
Many edge and contour detection algorithms give a soft-value as an output and the final binary map is commonly obtained by applying an optimal threshold.

We benefit from transfer learning using a pre-trained CNN for feature learning.
Deep-RBF Networks Revisited: Robust Classification with Rejection
On the other hand, deep-RBF networks assign high confidence only to the regions containing enough feature points, but they have been discounted due to the widely-held belief that they have the vanishing gradient problem.
Exploiting generalization in the subspaces for faster model-based learning
Generalization and faster learning in a subspace are due to many-to-one mapping of experiences from the full-space to each state in the subspace.
