deepcausalmmm 1.0.20

Causal Deep Learning marketing-mix modeling library with response curves

DeepCausalMMM

Advanced Marketing Mix Modeling with Causal Inference and Deep Learning

Development history

A substantial part of the design and prototyping was done locally before this repository was published on GitHub. The public commit history therefore reflects integration, hardening, documentation, tests, and packaging of that prior work more than a day-by-day log of initial exploration. You may see bursts of commits (e.g. around releases or doc pushes) and quieter periods in between; that pattern is typical when integrating a working prototype into an open-source layout rather than indicating only the span of weeks visible on GitHub.

Manual Installation

# Clone repository
git clone https://github.com/adityapt/deepcausalmmm.git
cd deepcausalmmm
pip install -e .

Dependencies Only

Same lower/upper bounds as pyproject.toml [project] dependencies (install libraries without the deepcausalmmm package):

pip install \
  "torch>=2.0" \
  "pandas>=1.5" \
  "numpy>=1.21,<2.0" \
  "plotly>=5.0" \

IMPORTANT: Version Compatibility

The code examples in this README are for version 1.0.19+

If you installed from PyPI previously (pip install deepcausalmmm), you might have v1.0.18 or below which has a completely different API. The examples below will NOT work for v1.0.18 and below.

For Current PyPI Users (v1.0.18 and below):

# Option 1: Upgrade to latest version from PyPi
pip install --upgrade deepcausalmmm
# OR shorthand
pip install -U deepcausalmmm

# Option 2: Install the development version (from GitHub)
pip install --upgrade git+https://github.com/adityapt/deepcausalmmm.git

# Option 3: Force reinstall if you have conflicts
pip install --upgrade --force-reinstall deepcausalmmm

API Changes in v1.0.19:

• New: pipeline parameter in ModelTrainer.train()
• Fixed: Proper data scaling without leakage
• Fixed: Correct attribution calculation
• New: ConfigurableDataGenerator.generate_mmm_dataset() method
• Removed: y_full_for_baseline parameter (data leakage fix)

# After training your model, prepare channel data for response curve fitting
# The data should have 'week_monday', 'spend', 'impressions', and 'predicted' columns

# Example: Create channel data from your model results
# Replace this with actual data extraction from your trained model
n_weeks = 104
channel_data = pd.DataFrame({
    'week_monday': pd.date_range('2024-01-01', periods=n_weeks, freq='W'),

# After training your model and fitting response curves...
# Create a DataFrame with fitted curve parameters for each channel
# Replace this with actual fitted parameters from your response curve fitting

Example Output:

Optimal Allocation: {'TV': 100000, 'Search': 420000, 'Social': 300000, ...}

Benchmarks

Example Validation (190 regions, 109 weeks, 13 channels, 7 controls):

• Training R²: 0.950 | Holdout R²: 0.842
• Performance Gap: 10.8% (indicating good generalization)
• Generalization Gap: 10.8% (reasonable out-of-sample performance)
• Temporal Split: Default holdout_ratio = 0.12 in config—about 96 training weeks and 13 holdout weeks on 109 observed weeks (burn-in padding in the pipeline may change logged lengths slightly)
