Time series numerical association rule mining variants

Nature-Inspired Algorithms for Time Series Numerical Association Rule Mining

✨ Features • 📦 Installation • 🚀 Basic example • 📚 Reference Papers • 🔑 License • 📄 Cite us

This framework is designed for numerical association rule mining in time series data using stochastic population-based nature-inspired algorithms[^1]. It provides tools to extract association rules from time series datasets while incorporating key metrics such as support, confidence, inclusion, and amplitude. Although independent from the NiaARM framework, this software can be viewed as an extension, with additional support for time series numerical association rule mining.

✨ Features

The current version of the framework supports two types of time series numerical association rule mining:

• Fixed Interval Time Series Numerical Association Rule Mining
• Segmented Interval Time Series Numerical Association Rule Mining

📦 Installation

To install NiaARMTS with pip, use:

pip install niaarmts

🚀 Basic example

from niapy.algorithms.basic import ParticleSwarmAlgorithm
from niapy.task import Task
from niaarmts import Dataset
from niaarmts.NiaARMTS import NiaARMTS

# Load dataset
dataset = Dataset()
dataset.load_data_from_csv('ts.csv', timestamp_col='timestamp')

# Create an instance of NiaARMTS
niaarmts_problem = NiaARMTS(
    dimension=dataset.calculate_problem_dimension(),  # Adjust dimension dynamically
    lower=0.0,  # Lower bound of solution space
    upper=1.0,  # Upper bound of solution space
    features=dataset.get_all_features_with_metadata(),  # Pass feature metadata
    transactions=dataset.get_all_transactions(),  # Dataframe containing all transactions
    interval='false',  # Whether we're dealing with interval data
    alpha=1.0,  # Weight for support in fitness calculation
    beta=1.0,  # Weight for confidence in fitness calculation
    gamma=1.0,  # Weight for inclusion in fitness calculation # if 0.0 then inclusion metric is omitted
    delta=1.0  # Weight for amplitude in fitness calculation # if 0.0 then amplitude metric is omitted
)

# Define the optimization task
task = Task(problem=niaarmts_problem, max_iters=100)  # Run for 100 iterations

# Initialize the Particle Swarm Optimization algorithm
pso = ParticleSwarmAlgorithm(population_size=40, min_velocity=-1.0, max_velocity=1.0, c1=2.0, c2=2.0)

# Run the algorithm
best_solution = pso.run(task)

# Output the best solution and its fitness value
print(f"Best solution: {best_solution[0]}")
print(f"Fitness value: {best_solution[1]}")
