Open Early Stage Researcher/PhD Position at Universidade de Santiago de Compostela (USC), Spain, for the NL4XAI project
__
Reference number: NL4XAI- ESR2
__
PhD research topic:__ From grey-box models to explainable models
Objectives: To define, design, develop and implement an agnostic-based approach for providing Natural Language explanations of Bayesian Networks reasoning using a linguistic imprecise knowledge representation and reasoning method. Taking as a starting point the interpretation of Bayesian variables, values and probability functions as imprecise quantified statements, the Bayesian reasoning process will be modelled as a quantified syllogism, which can be solved as a mathematical programming problem.
The target is to propose, test and validate models for explaining in Natural Language different reasoning schemes, such as predictive, diagnostic or inter-causal, with an efficient implementation for addressing scalability problems which may occur in large Bayesian Networks. The explanation models will be based both in the agnostic-based approach herein considered as well as in the results of ESR3.
The theoretical contributions of this research will be validated in:
Expected Results: A fully functional web service coming from:
Host institution: Centro Singular de Investigación en Tecnoloxías Intelixentes- CiTIUS, Universidade de Santiago de Compostela- USC (Spain)
PhD Enrollment: Universidade de Santiago de Compostela-USC (Spain)
The USC hosts more than 3,000 PhD students and has been awarded the “HR Excellence in Research” by the EC under the HRS4R process. Currently, the CiTIUS hosts 31 senior researchers, which have been selected by an external scientific advisory board, and a total of about 100 researchers. During the period 2016-2019, CiTIUS researchers have published more than 160 SJR journal papers and got more than 10,5 M€ from competitive R&D funds, being one third of them in collaboration with the industry sector. CiTIUS researchers have also promoted 3 new spin-offs.
General requirements:
Mobility: At the time of recruitment, the researcher must not have resided or carried out his/her main activity (work, studies, etc.) in Spain for more than 12 months in the 3 years prior to recruitment date. Time spent as part of a procedure for obtaining refugee status under the Geneva Convention is not taken into account.
Career: When starting their contract (expected in May 2022), selected researchers should be within the first four years of his/her research careers and not have been awarded a doctoral degree prior to the application.
The candidate must be working exclusively for the action.
