Decentralized Vehicle Coordination: The Berkeley DeepDrive Drone Dataset
Decentralized multiagent planning has been an important field of research in
robotics. An interesting and impactful application in the field is
decentralized vehicle coordination in understructured road environments. For
example, in an intersection, it is useful yet difficult to deconflict multiple
vehicles of intersecting paths in absence of a central coordinator. We learn
from common sense that, for a vehicle to navigate through such understructured
environments, the driver must understand and conform to the implicit "social
etiquette" observed by nearby drivers. To study this implicit driving protocol,
we collect the Berkeley DeepDrive Drone dataset. The dataset contains 1) a set
of aerial videos recording understructured driving, 2) a collection of images
and annotations to train vehicle detection models, and 3) a kit of development
scripts for illustrating typical usages. We believe that the dataset is of
primary interest for studying decentralized multiagent planning employed by
human drivers and, of secondary interest, for computer vision in remote sensing
settings.Comment: 6 pages, 10 figures, 1 tabl
Student groups of complementary skills developing artificial intelligence solutions for natural sciences -- an authentic research education approach suitable for wide adoption
We report a methodology in which students gain experience in authentic
research by developing artificial intelligence (AI) solutions for researchers
in natural sciences. While creating education benefits for students, our
approach also directly benefits scientists, who get an opportunity to evaluate
the usefulness of machine learning for their specific needs. In order to
accomplish this, we work with research laboratories that reveal/specify the
needs they have, and then our student teams work on the discovery, design, and
development of an AI solution for unique problems using a consulting-like
arrangement. Our design addresses common barriers which appear in most existing
authentic research education approaches and thus is suitable for wide adoption
at various schools. To date, our group has been operating at New York
University (NYU) for five consecutive semesters and has engaged more than
seventy students, ranging from first-year college students to master's
candidates, and worked on more than 15 projects with 14 collaborators
Identification of the Proliferation/Differentiation Switch in the Cellular Network of Multicellular Organisms
The proteināprotein interaction networks, or interactome networks, have been shown to have dynamic modular structures, yet the functional connections between and among the modules are less well understood. Here, using a new pipeline to integrate the interactome and the transcriptome, we identified a pair of transcriptionally anticorrelated modules, each consisting of hundreds of genes in multicellular interactome networks across different individuals and populations. The two modules are associated with cellular proliferation and differentiation, respectively. The proliferation module is conserved among eukaryotic organisms, whereas the differentiation module is specific to multicellular organisms. Upon differentiation of various tissues and cell lines from different organisms, the expression of the proliferation module is more uniformly suppressed, while the differentiation module is upregulated in a tissue- and species-specific manner. Our results indicate that even at the tissue and organism levels, proliferation and differentiation modules may correspond to two alternative states of the molecular network and may reflect a universal symbiotic relationship in a multicellular organism. Our analyses further predict that the proteins mediating the interactions between these modules may serve as modulators at the proliferation/differentiation switch
