Extract relevant features from different domain.

[sanbuddhacharyas]

It takes a long time to extract all domain features so, How can I extract only relevant features from all three domains?
Please help!!!

Can you elaborate on what do you understand by "relevant features"?
Usually, relevant features can be selected before feature extraction if you have some domain-knowledge on the most adequate features for your data. Alternatively, relevant features can also be selected after the feature extraction by applying feature selection methods.

1. Download the features.json and select each feature you want to use by changing the use parameter (yes or no value).

2. Load the customized json using the tsfel.load_json method.

import tsfel
import pandas as pd
 
# load dataset
df = pd.read_csv('Dataset.txt')
 
# Retrieves your pre-defined feature configuration file
cfg = tsfel.load_json(your_json_path)

# Extract features
X = tsfel.time_series_features_extractor(cfg, df)
