Wenyu Chiou

I use human evidence to evaluate AI decisions, and build checks that keep agents within clear limits.

My work connects human–environment modeling with evidence-linked scientific workflows.

Selected work

From a problem to inspectable evidence

A plausible AI decision is not necessarily a realistic or valid one. I compare it with human evidence, check its limits, and trace what happens next.

People and their environment

Human surveys inform behavioral models; simulated households make adaptation choices under flood and resource constraints.

Evidence

Evidence-linked scientific work

AI research agents handle literature and tasks. I build tools that make sources, validation checks, and workflow state inspectable.

Evidence

Human respondents provide evidence. Simulated household agents and AI research agents are models and software, not people. These projects share a research approach, not one integrated published system.

01

Human-Grounded LLM Evaluation

Can AI-generated flood-insurance answers reflect how real households make decisions?How I approached it I compared real household surveys with profile-based LLM responses using measurement checks, decision-pathway analysis, and repeated runs.What it contributes A way to detect differences in household variation and decision relationships that average answers alone can hide.
Methods
Evaluation design · Psychometrics and SEM · Stability analysis
Boundaries
The interactive examples use synthetic records, not individual survey responses or research results.

FLOODABM

How do household choices change flood losses and the resources available next year?How I approached it I built the household decision model and connected adaptation choices to catastrophe, insurance, and financial mechanics.What it contributes A traceable link from household adaptation choices to losses, insurance outcomes, and resources in later years.
Methods
Agent-based modeling · Coupled simulation · Risk systems
Boundaries
Simulated household agents model adaptation; they are not an integrated LLM system.

WAGF

What stops an invalid AI proposal from changing a simulation?How I approached it I designed the validation and repair path that checks an agent proposal before the simulation state can change.What it contributes An inspectable proposal-to-action boundary: invalid actions are blocked, repaired, and checked before execution.
Methods
Structured outputs · Constraint validation · Auditable repair
Boundaries
Demonstrations illustrate validation behavior, not a real-world safety guarantee.

Decision Observatory

Follow the evidence behind a decision.

Two applications, one method: compare with human evidence, check the proposal, and inspect what changes. Select an object or a step to follow its source.

Decision Observatory

Evidence enters. Decisions stay inspectable.

Evaluation

  1. Human evidence

    Measured constructs and reported choices establish the empirical reference.

    Published evidence
  2. Context

    A label-blind synthetic profile carries only approved attributes into the prompt.

    Illustrative example
  3. LLM proposal

    Repeated model runs produce a choice and a concise rationale for comparison.

    Illustrative example
  4. Validation / repair

    Checks compare direction, subgroup behavior, and run-to-run stability without exposing respondent records.

    Public artifact
  5. Consequence

    The result becomes an evaluation finding, not a claim that the model represents a person.

Governance

  1. Human evidence

    Behavioral and physical constraints define what a plausible action must respect.

    Published evidence
  2. Context

    A synthetic agent state limits the actions the model may propose.

    Illustrative example
  3. LLM proposal

    The LLM returns a structured proposal rather than mutating the simulation directly.

    Illustrative example
  4. Validation / repair

    Validators reject invalid fields, request targeted repair, and retain an audit trace.

    Public artifact
  5. Consequence

    Only an accepted proposal updates the coupled model state.

    Illustrative example

Simulation

  1. Human evidence

    Survey evidence and public flood-risk sources ground household behavior.

    Published evidence
  2. Context

    Household tenure, risk perception, resources, and exposure form the decision context.

    Published evidence
  3. Agent decision

    Agents choose adaptation, insurance, or no action under modeled constraints.

    Public artifact
  4. Validation / repair

    Model checks keep behavioral, financial, and physical state transitions consistent.

    Public artifact
  5. Consequence

    Flood losses and adaptation alter the household and environmental state for the next cycle.

Ideas shared in public

Selected posts I shared on LinkedIn, with links to the original context.

Beyond predicting a choice: is the decision process coherent?

My perspective on testing the factors behind a simulated preference, rather than treating a higher predicted probability as sufficient evidence of human-like behavior.
