aind-dynamic-foraging

A repository for the Dynamic Foraging task and its associated curricula.

---

📋 General instructions

This repository follows the project structure laid out in the Aind.Behavior.Services repository.

---

🔧 Prerequisites

Pre-requisites for running the project can be found here.

---

🚀 Deployment

For convenience, once third-party dependencies are installed, Bonsai and python virtual environments can be bootstrapped by running:

./scripts/deploy.ps1

from the root of the repository.

⚙️ Generating settings files

The Dynamic Foraging task is instantiated by a set of three settings files that strictly follow a DSL schema. These files are:

• task_logic.json
• rig.json
• session.json

Examples on how to generate these files can be found in the ./Examples directory of the repository. Once generated, these are the the only required inputs to run the Bonsai workflow in ./src/main.bonsai.

The workflow can thus be executed using the Bonsai CLI:

"./.bonsai/bonsai.exe" "./src/main.bonsai" -p SessionPath=<path-to-session.json> -p RigPath=<path-to-rig.json> -p TaskLogicPath=<path-to-task_logic.json>

However, for a better experiment management user experience, it is recommended to use the provided experiment launcher below.

[> ] CLI tools

Task CLI

The platform exposes a few CLI tools to facilitate various tasks. Tools are available via:

uv run dynamic-foraging <subcommand>

for a list of all sub commands available:

uv run dynamic-foraging -h

You may need to install optional dependencies depending on the sub-commands you run.

Curriculum CLI

Curricula are available via the curriculum CLI entry point. For a full list of commands:

uv run curriculum -h

list - List Available Curricula

uv run curriculum list

init - Initialize a Curriculum

Creates an initial trainer state for enrolling a subject in a curriculum.

# Start at the first stage
uv run curriculum init --curriculum coupled_baiting --output initial_state.json

# Start at a specific stage
uv run curriculum init --curriculum coupled_baiting --stage s_stage_1 --output initial_state.json

run - Run a Curriculum

Evaluates a curriculum based on session data and current trainer state.

uv run curriculum run \
  --data-directory /path/to/session/data \
  --input-trainer-state current_state.json \
  --output-suggestion /path/to/output

Force a specific curriculum:

uv run curriculum run \
  --data-directory /path/to/session/data \
  --input-trainer-state current_state.json \
  --curriculum coupled_baiting \
  --output-suggestion /path/to/output

version / dsl-version - Show Versions

uv run curriculum version      # Package version
uv run curriculum dsl-version  # Underlying DSL library version

---

Typical curriculum workflow

1. List available curricula:

   uv run curriculum list

2. Initialize a subject:

   uv run curriculum init --curriculum coupled_baiting --output trainer_state.json

3. After a session, evaluate progress:

   uv run curriculum run \
     --data-directory /path/to/session/data \
     --input-trainer-state trainer_state.json \
     --output-suggestion /path/to/output

4. Use the suggestion for the next session: The suggestion.json output can be passed as --input-trainer-state for the next session.

Style guide

To keep things clear, the following naming conventions are recommended:

• Policies should start with p_ (e.g., p_identity_policy)
• Policy transitions should start with pt_
• Stages should start with s_ (e.g., s_stage1)
• Stage transitions should start with st_ and be named after the stages they transition between (e.g., st_s_stage1_s_stage2)

Define the following modules within a curriculum:

• metrics: Defines (or imports) metrics classes and how to calculate them from data
• stages: Defines the different stages of the task, including task settings and optionally policies
• curriculum: Defines transitions between stages and generates the entry point to the application

---

🔍 Primary data quality-control

Once an experiment is collected, the primary data quality-control script can be run to check the data for issues. This script can be launcher using:

uv run dynamic-foraging data-qc <path-to-data-dir>

🔄 Regenerating schemas

DSL schemas can be modified in ./src/aind_behavior_dynamic_foraging/rig.py (or (...)/task_logic.py`).

Once modified, changes to the DSL must be propagated to json-schema and csharp API. This can be done by running:

uv run dynamic-foraging regenerate
