deepretail's Introduction

DeepRetail

Python package on deep learning AI and machine learning for Retail

This package is developed by the AI team at VIVES University of Applied Sciences and is used in our research on demand forecasting.

Getting started

Installation

Install python3.7+
Create a virtual env where you want to install:
```
$> python3 -m venv retailanalytics
```
Activate the environment
```
$> source retailanalytics/bin/activate
```
Install the package with pip
```
$> pip install DeepRetail
```

Use hierarchical modelling

import pandas as pd
from DeepRetail.transformations.formats import transaction_df
from DeepRetail.forecasting.statistical import StatisticalForecaster

# Load
df = pd.read_csv('daily_data.csv', index_col=0)

# Get a sample 
sampled_df = df.sample(20)

# Convert to transaction
t_df = transaction_df(sampled_df)

# Define the parameters
freq = 'M'
h = 4
holdout = True
cv = 2
models = ['ETS', 'Naive']

# Convert columns to datetime
sampled_df.columns = pd.to_datetime(sampled_df.columns)

# Resample columns to montly frequency
sampled_df = sampled_df.resample('M', axis=1).sum()

# Define the forecaster
forecaster = StatisticalForecaster(models = models, freq = freq)

# Fit the forecaster
forecaster.fit(sampled_df, format = 'pivoted')

# Predict
forecast_df = forecaster.predict(h = h, cv = cv, holdout = holdout)
forecast_df.head()
