PhD on contextualizing generative AI systems in structured data

2 dagen geleden

Amsterdam, Nederland Centrum Wiskunde & Informatica Voltijd

Job description

Goal of the DataLibra project
Approximately 120 zettabytes of data has been collected worldwide but less than 1% is actually
used. Structured data, e.g. tables, spreadsheets, and relational databases, is prevailing in
organizations and typically informs important decisions in healthcare, governments and finance.
Yet, while AI has demonstrated a high impact on applications on text and images, proportional
progress on structured data is lacking. With the DataLibra project, we aim to close this gap, by
developing AI models and tools for structured data (Table Representation Learning), to help
organizations, of any size, domain, and level of data literacy, get insights from structured data,
efficiently, accurately and securely.


Goal of this PhD project
Following recent developments in AI, large language models (LLMs) have been explored for data
analytics tasks (e.g. text-to-sql), but show limited accuracy in domain-specific contexts with
structured data. In this project, we will investigate and design interactive intelligent systems for
data analytics tasks, while accounting for two key challenges: trustworthiness of the outputs
(factuality), and security constraints of proprietary data contexts as in healthcare, enterprises, and
governments. Potential directions to explore are agentic systems, retrieval augmented generation,
(instruction) fine-tuning, and others.


What you will be doing
 Inform a research agenda on the PhD topic for a timespan of four years.
 Develop methods and systems for contextualizing generative AI for analytics over
structured data.
 Actively collaborate with other researchers in the DataLibra project (students, 4-5 PhDs,
postdocs, PI) and external collaborators (e.g. Amsterdam UMC, University of Amsterdam).
 Communicate research outcomes through papers and presentations at conferences,
workshops and other (scientific) gatherings.
 Assist in relevant teaching activities at universities, such as thesis supervision and assisting
in courses.

Requirements

- A master (or equivalent) in computer science, artificial intelligence or similar.
- Self-drive, creativity, rigor, ownership, and excitement to push research in TRL forward.
- Theoretical knowledge of, or experience with, data management, human-computer
interaction, and/or machine learning such as representation and generative learning.
- Programming skills, e.g. Python, Java, or C++.
- Excellent command in English, verbal and written.
- Prior experience as a research assistant during (under)graduate studies is advantageous

Terms and conditions

The terms of employment are in accordance with the Dutch Collective Labour Agreement for Research Centres ("CAO-onderzoeksinstellingen"). The initial labour agreement will be for a period of 18 months. After a positive evaluation, the agreement will be extended by 30 months. The gross monthly salary, for a PhD student on a full time basis, is € 2,781 during the first year and increases to € 3,562 over the four year period. Employees are also entitled to a holiday allowance of 8% of the gross annual salary and a year-end bonus of 8.33%. CWI offers attractive working conditions, including flexible scheduling and help with housing for expat employees.
