Review of the Research on the Identification of Electrical Fire Trace Evidence
AbstractIn this paper, we review the research results about the identification of the electrical fire trace evidence and the fire reason recognition. We point out the existing problems and put forward the corresponding suggestions to promote the development of the cause of the fire investigation and make it better to serve for the work of fire investigation
Energetic Variation with the Anderson Hamiltonian
We study the variation problem associated with the Anderson Hamiltonian in
2-dimensional torus in the paracontrolled distribution framework. We obtain the
existence of minimizers by the direct method in the calculus of variations, and
show that the Euler-Lagrange equation of the energy functional is an elliptic
singular stochastic partial differential equation with the Anderson
Hamiltonian. We also establish the L^2 estimates and Schauder estimates for the
minimizer as weak solution of the elliptic singular stochastic partial
differential equation.Comment: arXiv admin note: text overlap with arXiv:2109.1042
Multiple closed geodesics on Finsler -dimensional sphere
In 1973, Katok constructed a non-degenerate (also called bumpy) Finsler
metric on with exactly four prime closed geodesics. And then Anosov
conjectured that four should be the optimal lower bound of the number of prime
closed geodesics on every Finsler . In this paper, we proved this
conjecture for bumpy Finsler if the Morse index of any prime closed
geodesic is nonzero.Comment: 15 pages. arXiv admin note: text overlap with arXiv:1504.07007,

Exploring Object Relation in Mean Teacher for Cross-Domain Detection
Rendering synthetic data (e.g., 3D CAD-rendered images) to generate
annotations for learning deep models in vision tasks has attracted increasing
attention in recent years. However, simply applying the models learnt on
synthetic images may lead to high generalization error on real images due to
domain shift. To address this issue, recent progress in cross-domain
recognition has featured the Mean Teacher, which directly simulates
unsupervised domain adaptation as semi-supervised learning. The domain gap is
thus naturally bridged with consistency regularization in a teacher-student
scheme. In this work, we advance this Mean Teacher paradigm to be applicable
for cross-domain detection. Specifically, we present Mean Teacher with Object
Relations (MTOR) that novelly remolds Mean Teacher under the backbone of Faster
R-CNN by integrating the object relations into the measure of consistency cost
between teacher and student modules. Technically, MTOR firstly learns
relational graphs that capture similarities between pairs of regions for
teacher and student respectively. The whole architecture is then optimized with
three consistency regularizations: 1) region-level consistency to align the
region-level predictions between teacher and student, 2) inter-graph
consistency for matching the graph structures between teacher and student, and
3) intra-graph consistency to enhance the similarity between regions of same
class within the graph of student. Extensive experiments are conducted on the
transfers across Cityscapes, Foggy Cityscapes, and SIM10k, and superior results
are reported when comparing to state-of-the-art approaches. More remarkably, we
obtain a new record of single model: 22.8% of mAP on Syn2Real detection
dataset.Comment: CVPR 2019; The codes and model of our MTOR are publicly available at:
