DeepPose: Human Pose Estimation via Deep Neural Networks
We propose a method for human pose estimation based on Deep Neural Networks
(DNNs). The pose estimation is formulated as a DNN-based regression problem
towards body joints. We present a cascade of such DNN regressors which results
in high precision pose estimates. The approach has the advantage of reasoning
about pose in a holistic fashion and has a simple but yet powerful formulation
which capitalizes on recent advances in Deep Learning. We present a detailed
empirical analysis with state-of-art or better performance on four academic
benchmarks of diverse real-world images.Comment: IEEE Conference on Computer Vision and Pattern Recognition, 201
Modular application of an Integration by Fractional Expansion (IBFE) method to multiloop Feynman diagrams
We present an alternative technique for evaluating multiloop Feynman
diagrams, using the integration by fractional expansion method. Here we
consider generic diagrams that contain propagators with radiative corrections
which topologically correspond to recursive constructions of bubble type
diagrams. The main idea is to reduce these subgraphs, replacing them by their
equivalent multiregion expansion. One of the main advantages of this
integration technique is that it allows to reduce massive cases with the same
degree of difficulty as in the massless case.Comment: 38 pages, 46 figures, 4 table
Module categories for permutation modular invariants
We show that a braided monoidal category C can be endowed with the structure
of a right (and left) module category over C \times C. In fact, there is a
family of such module category structures, and they are mutually isomorphic if
and only if C allows for a twist. For the case that C is premodular we compute
the internal End of the tensor unit of C, and we show that it is an Azumaya
algebra if C is modular. As an application to two-dimensional rational
conformal field theory, we show that the module categories describe the
permutation modular invariant for models based on the product of two identical
chiral algebras. It follows in particular that all permutation modular
invariants are physical.Comment: 25 pages, some figures. v2: minor changes, some figures added.
