Postdoc position - Research Fellow in AI Evaluation - VRAIN - Valencia

[César Ferri]

Postdoc position - Research Fellow in AI Evaluation

Key details:

Position for at least 21 months (starting early 2025); extensions beyond that period likely depending on results and associated projects.
Salary will be 42000 EUR (gross salary per year distributed into 12+2 pays).
Job will be located at VRAIN (Technical University of Valencia), one of the largest AI research centres in Europe.

Working environment:

This is an exciting opportunity to join a leading research team in AI evaluation, enjoying an international atmosphere with a network of collaborations world-wide and playing a major role steering the community (e.g., aievaluation.substack.com) with recent publications in top venues such as Nature, Science, NeurIPS, AAAI and IJCAI. The candidate will work alongside the DMIP team at VRAIN, under the direction of Jose Hernandez-Orallo (josephorallo.webs.upv.es).

Research details:

• The low predictability of AI systems is a challenge that has been intensified by the widespread use of general-purpose AI, now directly used for thousands of tasks by millions of people, in an unprecedented upturn in AI penetration. Yet users cannot anticipate whether the system is going to be valid for a new task instance. This is an urgent need that requires a better evaluation of the capabilities and safety of AI systems.
• In this context, the research fellow will perform world-class research to understand the space of AI predictability, its metrics, and evaluation, collecting system, task and possibly user feedback data to train validity predictors. These validity predictors anticipate a metric of performance or safety given the context of use <system, instance, user>. The main goal is to develop theoretical and experimental research to conceptualise this space, and build monitors that supervise AI systems.
• For the notion of Predictable AI, we suggest interested candidates to have a look at arxiv.org/pdf/2310.06167.

More research context:

Other relevant papers that illustrate the kind of research we do:

• Evaluating General-Purpose AI (ebooks.iospress.nl/doi/10.3233/FAIA240459). It focuses on how to characterise GPAI, but it contains definitions of capability, generality, subject characteristic curves, etc.
• Measurement layouts (arxiv.org/pdf/2309.11975): this is a specific approach using MCMC to model the behaviour of underlying agents (it's in a 3D world, but we have developed similar evaluation models for LLMs).
• This is more on methodology (science.org/doi/full/10.1126/science.adf6369), but it emphasises why instance-level evaluation is crucial.
• How psychometrics should be used in AI (arxiv.org/pdf/2310.16379), talks about predictive and explanatory power in evaluation, and validity.
• This recent Nature paper introduces some methodological innovations into AI evaluation (e.g., three-valued analysis), summarised here: aievaluation.substack.com/p/2024-september-ai-evaluation-digest.

Key responsibilities:

RESEARCH (proper): Research literature reviews, brainstorming research ideas, experimental research (testing AI systems, analysing results, visualisation), problem formulation (formalisation), writing papers and reports, etc.
RESEARCH (related): Dissemination of results by giving talks, attending/organising conferences, developing collaborations, contributing to further funding applications, etc.

Requirements:

• A PhD in a relevant field (Computer Science / Cognitive Sciences / Psychology / Engineering / Maths / Physics / ...) is essential.
• Fluency in English is essential.
• The ability to demonstrate potential for research and publication at the highest level is essential.
• A strong interest in engagement in international and cross-disciplinary teams (AI, cognitive science, etc.) is essential.
• An interest in AI evaluation and Predictable AI and other areas of the project (including those outside the candidate's own areas of expertise) is essential.
• Strong expertise in machine learning is desirable, but some basic knowledge is essential.
• Expertise in large language models is desirable.
• Expertise in AI evaluation is an advantage.
• Expertise in AI safety is an advantage.

Application:

• Candidates will send an email to strategy.pr...@gmail.com with subject starting with "[PredAIT]", attaching exactly one PDF file that includes their CV, cover letter (no more than 1000 words) with ideas or reflections on the topics relevant to this position (see above) and the names and contact details of two referees who are familiar with the candidate's work.
• Deadline: 20th November 2024, AoE.
• Candidates will be required to have a PhD that has been awarded or recognised in the EHEA space (ehea.info/) and can obtain the right to work in the EU (the university will help with the info for the visa if needed).

Equality:

We celebrate diversity and encourage applications from all qualified candidates, particularly those from under-represented groups. We are committed to creating an inclusive and supportive environment for all.
