FP7-ICT-2011-9 STREP proposal<br />
18/01/12 v1 [Dynact]<br />
v) Risk assessment and contingency plan<br />
Some of the objectives of the proposals, reflected in the above work packages, admittedly involve a certain<br />
degree of risk.<br />
In particular, the development of inference algorithms for imprecise hidden Markov models is cutting edge<br />
research at this time, while the formulation of a general theory for arbitrary imprecise-probabilistic graphical<br />
models poses a beautiful but serious challenge. The same can be said for the development of dynamical<br />
discriminative models, able to exploit the information provided by motion dynamics and couple it with the<br />
state-of-the-art performances of discriminative methods. Finally, the classification of “precise” graphical<br />
models is also subject of current, challenging research: this is in particular true for the theory of<br />
metric/manifold learning for dynamical models. Its extension to imprecise-probabilistic graphical models is<br />
an ambitious goal, which will be crucial to the success of the project.<br />
These risks are balanced by the strong skills of the four academic partners in their respective area of<br />
expertise, and the specific features of the Coordinator with his interdisciplinarity expertise in both the<br />
applications object of this project (action, gesture and identity recognition) and its theoretical side (theory of<br />
imprecise probabilities and classification of dynamical models).<br />
From a general point of view, as we mentioned above, the project is articulated into three different pipelines.<br />
Overall the project is designed as a “pincer movement”, in which different arms are designed to attack the<br />
problem from different angles in a complementary and cooperative manner. While a coherent formulation of<br />
inference and classification algorithms for imprecise-probabilistic graphical models is a challenge that<br />
cannot be met by simply building on existing results, WP4 activities (data gathering and feature extraction)<br />
are characterised by a lower level of risk, while, given OBU's expertise in computer vision applications and<br />
software development, we not envisage any insurmountable difficulty with integration and testing (WP5).<br />
As for WP5's different scenarios, our strong industrial partner Dynamixyz has the necessary background to<br />
guarantee proper validation and testing in the virtual animation context, while OBU has running projects and<br />
extensive expertise in action recognition, gait identification, gaming and entertainment, feature selection and<br />
extraction, autonomous navigation and robotics.<br />
Concerning the consortium's management, three of the four academic partners have smoothly and fruitfully<br />
worked together in recent years without any particular issue: it seems therefore reasonable to expect the same<br />
will happen in the course of this project as well.<br />
To moderate risk, alternative approaches are considered from the start in the different workpackages, in order<br />
to ensure at least one of them will deliver within the desired time frame. For instance, in work package 2 we<br />
have foreseen to pursue several different alternative options to the classification of imprecise Markov and<br />
graphical models, based on clustering, structured kernel learning, and possible compressed sensing.<br />
Further actions will be assessed by the steering committee in its periodic meetings and through informal<br />
contacts and video conferences between the partners. All actions deemed necessary will be proactively<br />
considered and enacted.<br />
