Workshop scope

About CALE-AI

AI systems increasingly operate not only as predictors, but also as interventions that can influence human decisions, preferences, trust, behavior, and long-term outcomes.

Foundation models, AI agents, recommender systems, conversational assistants, digital health systems, educational technologies, and decision-support tools increasingly interact with users repeatedly and adaptively.

Traditional evaluation based primarily on predictive accuracy, offline metrics, short-term engagement, or one-time user studies is often insufficient for understanding these systems.

CALE-AI focuses on how AI interventions can be rigorously evaluated in terms of their causal, longitudinal, behavioral, and human-centered effects.

Definition of an AI intervention

“A user-facing AI action or policy—such as a recommendation, explanation, nudge, warning, conversational response, or agent action—that changes the information, options, timing, or action environment presented to a person.”

The workshop considers both intended behavior-change interventions and incidental effects of AI systems on preferences, trust, reliance, autonomy, and well-being.

Main workshop themes

Workshop Themes

01

Causal Evaluation of AI Interventions

Randomized controlled experiments, A/B tests, micro-randomized trials, sequential multiple-assignment randomized trials, quasi-experimental designs, interrupted time series, difference-in-differences, causal machine learning, counterfactual evaluation, and off-policy evaluation.

Focus on separating intervention effects from self-selection, context, and system adaptation.

02

Longitudinal and Dynamic Effects

Repeated exposure, cumulative effects, delayed effects, sustained effects, carryover effects, habituation, reactance, preference formation, time-varying confounding, non-stationarity, human–AI co-adaptation, and feedback loops.

03

Responsible Intervention Design

User-endorsed goals, autonomy, informed consent, transparency, fairness, privacy, reversibility, contestability, non-manipulation, and unintended harms.

04

Human-Centered Evaluation Metrics

Metrics beyond accuracy, engagement, and satisfaction, including behavioral outcomes, cognitive outcomes, health, sustainability, trust, appropriate reliance, user agency, well-being, durability, and distributional effects.

05

Evaluation Infrastructure and Standards

Reporting frameworks, intervention taxonomies, evaluation cards, datasets, benchmarks, simulation environments, reproducibility, cross-domain comparison, and standardized protocols.

Research agenda

Central Research Questions

RQ1

How should causal estimands and study designs be defined when interventions are repeated, users and systems co-adapt, and earlier responses determine later exposures?

RQ2

How should immediate, sustained, cumulative, delayed, and unintended human effects be measured across application-specific time horizons?

RQ3

Who determines desirable behavioral outcomes, and how can AI interventions remain effective without undermining autonomy, consent, fairness, or non-manipulation?

RQ4

What shared reporting standards, datasets, metrics, and evaluation infrastructure are needed for responsible and reproducible comparison?

Workshop structure

Workshop Format

CALE-AI is planned as a one-day, in-person workshop. The program will combine contributed paper presentations, invited talks, lightning talks, an interactive poster session, a moderated panel, structured breakout discussions, and a final plenary discussion.

Approximately half of the workshop time is dedicated to presenting and discussing submitted research.

Breakout themes

  • Causal and longitudinal evaluation
  • Effectiveness, autonomy, and manipulation
  • Shared datasets, benchmarks, and evaluation standards

Expected outputs

Community Outcomes

AI Intervention Taxonomy

A shared taxonomy categorizing interventions based on mechanism, adaptation level, context, intended outcome, and possible unintended effects.

AI Intervention Evaluation Card

A structured reporting framework covering the intervention, comparator, causal estimand, assumptions, target population, adaptation, time horizon, outcomes, uncertainty, subgroup effects, autonomy, and possible harms.

Research Agenda

A community-developed agenda for datasets, benchmarks, longitudinal study designs, causal evaluation, reproducible protocols, and future research infrastructure.

Workshop participants may also be invited to contribute to a collaborative position paper or public post-workshop report.
