Smart City Ideation Challenge (submission is now closed)

To deepen the use of artificial intelligence (AI) for digital transformation, AI Singapore is excited to launch the Smart City Ideation Challenge with the aim of seeking insights from the global AI community on “What are the AI problems worth solving towards Smart City Sustainability?”

The problem statements are expected to be:

1) Impactful to the digital economy, and

2) Feasible to develop into AI challenges

We seek proposals under 2 categories towards building resilience and optimising resources in the digital economy:

  • Spam & Misinformation: The problem statements under this category should explore how to leverage AI for fast detection and intervention of misinformation or phishing attacks in multilingual and/or multimodal settings.
  • Sustainability & Carbon Neutrality: The problem statements under this category should investigate how to utilise AI for the recovery of local resources from major waste streams, including electronic, plastic and food wastes.


  • Any individual who is at least 18 years of age can form/join a team to submit a proposal
  • A team can comprise 1 to 5 members
  • An individual can be on no more than TWO teams
  • A team can submit no more than ONE proposal per category

Submission Guideline

Your proposal should contain the following components:

  • Problem statement
    Please give a description (no more than 300 words) of the problem to be solved and its scope.
  • Value proposition
    Please describe (no more than 300 words) how the proposed problem impacts industry needs and/or the socioeconomic needs of Singapore.
  • Existing solutions
    Please describe (no more than 500 words) existing solutions in the market and/or state-of-the-art research findings for the identified problem.
  • Dataset construction
    Please propose a detailed plan (no more than 500 words) on how to construct a dataset for solution development, including possible data sources, dataset schema, size, characteristics, etc.
  • Evaluation metrics
    Please describe (no more than 500 words) the evaluation metrics to assess potential solutions to the identified problem, including judging criteria, weight, and justifications.
  • Feasibility analysis
    Please analyse (no more than 500 words) the feasibility of using the proposal to harvest meaningful AI solutions and describe what some potential solutions might be.

Evaluation Criteria

Submitted proposals will be reviewed by a panel of experts based on the following criteria:

  • Research quality
    i.e., problem impact, relevance, novelty, and robustness
  • Competition quality
    i.e., the feasibility and readiness to turn the proposal into a meaningful AI challenge (refer to Kaggle competitions for quality)
  • Presentation quality
    i.e., understandability, accuracy, completion, clarity, and neatness

Post evaluation, up to SIX finalists (up to three per category) will be announced and invited to give an in person 15-minute final pitch presentation on the Smart City Day of WSDM. The winners will be ranked and awarded at the event, according to the scores provided by the judging panel and the live audience based on the above criteria.
