“Artificial intelligence for the Sciences” (AI4theSciences) is an innovative, interdisciplinary and intersectoral PhD programme, led by Université Paris Sciences et Lettres (PSL) and co-funded by the European Commission. Supported by the European innovation and research programme Horizon 2020-Marie Sklodowska-Curie Actions, AI4theSciences is uniquely shaped to train a new generation of researchers at the highest academic level in their main discipline (Physics, Engineering, Biology, Human and Social Sciences) and master the latest technologies in Artificial Intelligence and Machine Learning which apply in their own field.
26 doctoral students will join the PSL university's doctoral schools in 2 academic cohorts to carry out work on subjects suggested and defined by PSL's scientific community. The 2020 call will offer up to 15 PhD positions on 24 PhD research projects. The candidates will be recruited through HR processes of high standard, based on transparency, equal opportunities and excellence.
Description of the PhD subject: “Advanced methods for enhancing interpretability of AI tools with application to the energy sector”
Context - Motivation
Standard practice of decision-making in energy systems relies largely on complex modelling chains to address technical constraints and integrate numerous sources of uncertainty. In this context, artificial intelligence (AI) based solutions are increasingly developed (1) to simplify modelling chains (e.g. via “value-oriented” approaches formulating trading decisions for Renewable Energy Sources (RES) producers without additional predictive models [Carriere 2019]), and (2) to improve performances due to higher learning capabilities compared to state-of-the-art methods (e.g. reinforcement learning method to reduce energy consumption of large plants [Filipe 2019]). The activity on AI for the energy sector includes also the proposition of deep neural network architectures tailored to large-dimension problems such as electricity price forecasting [Toubeau 2019], determine dynamic states [Misyris 2019] or power flow optimization [Donon 2020]. Energy systems are exposed to increasing interactions at multiple scales (distributed generation, flexible prosumers, international exchanges, multi-energy transactions, etc.). Decision makers of the energy sector need to understand how decision-aid tools construct their outputs from the data representing such dynamic multi-scale systems. AI-based tools for different management functions of the energy system are often seen as black-box models and this penalizes their acceptability by the end-users (traders, power system operators a.o.). The lack of interpretability of AI tools is a major challenge for a wider adoption of AI in the energy sector and a fundamental requirement to better support humans in the decision-aid process.
Agents of energy systems expect high levels of reliability for the various services provided by these systems (energy, ancillary services, flexibility, etc.): this ensures proper sizing of security measures and quality of service for end-users. As energy systems are impacted by multiple uncertainty sources (e.g. available resource of distributed renewable plants, climate change, market conditions, agent behaviors), developed AI tools should not only be performant on average situations, but be able to guarantee robust solutions in the case of extreme events, which may be a joint realization of multiple extreme conditions (e.g. on available resources, market conditions and grid state) and humans make decisions under high stress levels. In general, state-of-the-art AI-based approaches require large amounts of data for training and show high dependability from the particular physical system or case-study. Another challenge is to explore symbolic reasoning to guarantee that the extracted knowledge, in addition to be interpretable to humans, can be transferred and generalized to different systems.
Scientific Objectives, Methodology & Expected results
The scientific objectives of this thesis are:
- To develop advanced methods for enhancing interpretability of AI tools with application to the energy sector
- To cover important use cases of AI application to the energy sector such as decision-aid under extreme events or abnormal conditions and trading in the context of evolving energy markets
- And finally, to integrate in the methodology how humans understand complex systems and take decisions informed by AI tools
The thesis will start with a review of the definition of AI interpretability and its developments in different disciplines. A focus will be placed on understandable representations of data-driven decision-aid models for human operators in the energy sector. Explainability metrics for AI tools will be developed for applications to the energy sector. In order to increase the interpretability of the AI models, two different paradigms borrowed from the computer science domain will be explored and further developed. Genetic programming [Koza 1992] will be used to derive a symbolic representation for the data-driven model that can take the form of a single equation or decision-rules that evolve together according to a specific reward function. An alternative is inductive programming [Gulwani2015], where a template (or structured format) of algebraic equations is used to characterize the state-action relation and enables the integration of human expert knowledge. The main goal is to produce symbolic representations of the knowledge that requirement minimum changes when applied to different systems or case-studies. Real-world use-cases will be considered to demonstrate the added value of the proposed tools for decision making in different applications. An example of such use-case is that of trading of the production of a virtual power plant (aggregation of wind and photovoltaic plants) to the day-ahead and ancillary service markets. The typical model chain involves as much as 12 models for forecasting RES production and market quantities and a last step of stochastic optimisation to derive trading decisions. This complex chain may be replaced by a single AI-based model. The adoption though of such AI-based approach by the trader depends on the capacity to interpret its outputs.
The proposed topic is interdisciplinary as it combines research in artificial intelligence, data science and optimization and energy. The international dimension is strong as it gathers researchers from Mines ParisTech-PSL and INESC TEC, both leaders in their field.
The candidate will pass a period of at least a year at INESC TEC (Porto, Portugal). This will permit, among others, to apply for a European Doctorate Label. Additional stays are envisaged to laboratories with related activity to the topic.
