IOD-CNN: Integrating Object Detection Networks for Event Recognition
Many previous methods have showed the importance of considering semantically
relevant objects for performing event recognition, yet none of the methods have
exploited the power of deep convolutional neural networks to directly integrate
relevant object information into a unified network. We present a novel unified
deep CNN architecture which integrates architecturally different, yet
semantically-related object detection networks to enhance the performance of
the event recognition task. Our architecture allows the sharing of the
convolutional layers and a fully connected layer which effectively integrates
event recognition, rigid object detection and non-rigid object detection.Comment: submitted to IEEE International Conference on Image Processing 201
A unified framework for verification techniques for object invariants
Object invariants define the consistency of objects. They have subtle semantics, mainly because of call-backs, multi-object invariants, and subclassing. Several verification techniques for object invariants have been proposed. It is difficult to compare these techniques, and to ascertain their soundness, because of their differences in restrictions on programs and invariants, in the use of advanced type systems (e.g., ownership types), in the meaning of invariants, and in proof obligations. We develop a unified framework for such techniques. We distil seven parameters that characterise a verification technique, and identify sufficient conditions on these parameters which guarantee soundness. We instantiate our framework with three verification techniques from the literature, and use it to assess soundness and compare expressiveness.peer-reviewe
Submission Tool for the DSpace-Based Learning Object Repository
4th International Conference on Open RepositoriesThis presentation was part of the session : Conference PostersThe poster briefly reports our experience with building Learning Object Repository based on DSpace and analyzes some problems we encountered with the submission system. The poster describes custom submission tool that can be used as an alternative to the DSpace submission system and provides useful extensions that allow connecting to the automatic keyword extraction services and generating of IMS and SCORM packages
Detecting and Grouping Identical Objects for Region Proposal and Classification
Often multiple instances of an object occur in the same scene, for example in
a warehouse. Unsupervised multi-instance object discovery algorithms are able
to detect and identify such objects. We use such an algorithm to provide object
proposals to a convolutional neural network (CNN) based classifier. This
results in fewer regions to evaluate, compared to traditional region proposal
algorithms. Additionally, it enables using the joint probability of multiple
instances of an object, resulting in improved classification accuracy. The
proposed technique can also split a single class into multiple sub-classes
corresponding to the different object types, enabling hierarchical
classification.Comment: IEEE Conference on Computer Vision and Pattern Recognition (CVPR),

The distribution of mass ratios in compact object binaries
Using the StarTrack population synthesis code we compute the distribution of
masses of merging compact object (black hole or neutron star) binaries. The
shape of the mass distribution is sensitive to some of the parameters governing
the stellar binary evolution. We discuss the possibility of constraining
stellar evolution models using mass measurements obtained from the detection of
compact object inspiral with the upcoming gravitational-wave observatories.Comment: 10 pages, uses spie.cls, Proc of the SPIE Conference "Astronomical

The Secrets of Salient Object Segmentation
In this paper we provide an extensive evaluation of fixation prediction and
salient object segmentation algorithms as well as statistics of major datasets.
Our analysis identifies serious design flaws of existing salient object
benchmarks, called the dataset design bias, by over emphasizing the
stereotypical concepts of saliency. The dataset design bias does not only
create the discomforting disconnection between fixations and salient object
segmentation, but also misleads the algorithm designing. Based on our analysis,
we propose a new high quality dataset that offers both fixation and salient
object segmentation ground-truth. With fixations and salient object being
presented simultaneously, we are able to bridge the gap between fixations and
salient objects, and propose a novel method for salient object segmentation.
Finally, we report significant benchmark progress on three existing datasets of
segmenting salient objectsComment: 15 pages, 8 figures. Conference version was accepted by CVPR 201
Stellar archaeology with Gaia: the Galactic white dwarf population
Gaia will identify several 1e5 white dwarfs, most of which will be in the
solar neighborhood at distances of a few hundred parsecs. Ground-based optical
follow-up spectroscopy of this sample of stellar remnants is essential to
unlock the enormous scientific potential it holds for our understanding of
stellar evolution, and the Galactic formation history of both stars and
planets.Comment: Summary of a talk at the 'Multi-Object Spectroscopy in the Next
