+# ACE-BB Dataset
+
+ACE-BB (Agentic e-Commerce - choice Behavior & Biases) is a set of experiments for studying how autonomous AI agents behave when shopping in e-commerce settings.
+The dataset enables controlled experiments on AI shopping behavior by providing synthetic tasks which evaluate agents' choice behavior & biases.

+
+## Dataset Description
+
+This dataset contains experimental data from studying how AI shopping agents behave in e-commerce settings:
+
+### Choice Behavior & Biases Experiments
+- 500 randomized scenarios per product category
+- Exogenous variation in:
+  - Product positions (2×4 grid layout)
+  - Platform tags (Sponsored, Overall Pick, Scarcity)
+  - Product attributes (price, rating, number of reviews)
+- Measures AI agent sensitivity to platform levers and product characteristics
+
+### Dataset Subsets
+
+- `choice_behavior`
+- `market_share`
+
+## Usage
+
+To reproduce experiments or run on new models, please refer to the [ACES codebase](https://github.com/mycustomai/ACE).
