Scikit-Learn is a popular machine learning library in Python that provides a wide range of algorithms for classification, regression, clustering, and more. It has a simple and easy-to-use API, making it a great choice for beginners and experts alike. Scikit-Learn also has a built-in support for time series forecasting with the TimeSeriesSplit and Backtesting modules.

TimeSeriesSplit

TimeSeriesSplit is a module in Scikit-Learn that splits a time series dataset into training and testing sets. It allows you to evaluate the performance of your model on unseen data and prevent overfitting. It works by randomly splitting the dataset into k-folds, where k is the number of splits you specify. It then trains the model on k-1 splits and evaluates it on the remaining split.

Backtesting

Backtesting is another module in Scikit-Learn that allows you to evaluate the performance of your time series forecasting model on historical data. It works by simulating the future by using the trained model to predict the next observation in the time series and adding it to the historical data. This process is repeated for each observation in the time series, and the accuracy of the predictions is measured using metrics such as mean absolute error (MAE) and root mean squared error (RMSE).

TensorFlow is a powerful and flexible open-source machine learning framework that provides a wide range of tools for building and training machine learning models. It has a strong focus on deep learning and provides a range of tools for building and training neural networks. TensorFlow also has built-in support for time series forecasting with the Prophet library.

Prophet

Prophet is a time series forecasting library in TensorFlow that provides a unified framework for time series forecasting. It was developed by Facebook and is widely used in industry and academia. Prophet provides a range of features, including trend and seasonality components, holiday effects, and missing data handling. It also provides a range of evaluation metrics, including mean absolute error (MAE), root mean squared error (RMSE), and R-squared.

Prophet Example

Here is an example of how to use Prophet to forecast time series data:

import tensorflow as tf
from tensorflow import keras
from tensorflow.keras import layers
from tensorflow_probability import distributions as td
from tensorflow_probability.keras import layer_normalization

# Load the data
data = keras.datasets.load_iris()

# Split the data into features and target
X = data.data
y = data.target

# Define the model
model = keras.Sequential([
    keras.layers.Dense(16, activation='relu', input_shape=(X.shape[1],)),
    keras.layers.Dense(8, activation='relu'),
    keras.layers.Dense(4, activation='relu'),
    keras.layers.Dense(1)
])

# Compile the model
model.compile(optimizer='adam', loss='mean_squared_error')

# Train the model
model.fit(X, y, epochs=100, batch_size=32)

# Make predictions
predictions = model.predict(X)

# Evaluate the model
mae = keras.metrics.mean_absolute_error(y, predictions)
rmse = keras.metrics.root_mean_squared_error(y, predictions)
r_squared = keras.metrics.r2_score(y, predictions)

In conclusion, Scikit-Learn and TensorFlow are both powerful tools for time series forecasting, but they have different strengths and weaknesses. Scikit-Learn provides a simple and easy-to-use API with built-in support for time series forecasting, while TensorFlow provides a powerful and flexible framework with built-in support for deep learning and time series forecasting with Prophet.
