Brief Description of the position
Geometric deep learning: Application to chemoinformatics
Keywords: graph theory, deep learning, machine learning, Python.
Duration : 8 to 10 months
Context
Conversely to machine learning on data encoded as vectors, learning a
prediction function on graphs arises different scientific bottlenecks.
First of all, by their non euclidean representation, use of classic
machine learning methods is non trivial. Some methods propose to embed
the graphs onto an euclidean space. However, such projections induce a
loss of structural information which may be difficult to control.
In the two last decades, some methods aimed to design graphs kernels or
graph edit distance approximation methods to avoid an arbitrary
representation of graphs as vectors. GREYC and LITIS laboratories from
Normandie University collaborate on the definition of these methods.
Since the emerging of deep learning methods, most of proposed approaches
were defined using vectors as inputs. As a consequence, graphs were
mostly apart of the scope of application of these methods, and graph
based machine learning can not profit of impressive deep learning advances.
However, since the pioneer work of Gori and Scarselli [1, 2], some
propositions were made to bridge the gap between graphs and deep
learning. One particular application of graph based machine learning is
chemoinformatics. Molecular compounds are naturally encoded as graphs
and graph based methods are of thus methods of choice when predicting
properties of molecules. Within AGAC regional project, the two
laboratories GREYC and LITIS put in common their expertise to design and
develop new machine learning methods based on graphs to be used in
chemoinformatics. The project includes aspects of graph edit distance
and kernels. A logic continuation is to study how geometric deep
learning may help to improve results on chemoinformatics. To achieve
this goal, we are recruiting a post doctoral researcher for 8 to 10 months.
This project will be supervised in close collaboration by LITIS (Rouen,
France) and GREYC (Caen, France) laboratories which have a strong exper-
tise on graph based machine learning methods. The chemical expertise
will be brought by COBRA laboratory (Rouen, France).
