Background

Sunspots are caused by the Sun's magnetic field and often appear in cycles, known as the solar cycle, which typically spans around 11 years. Scientists have been observing these cycles for centuries, noticing periodic variations in sunspot numbers. Machine learning algorithms can help in deciphering these intricate patterns, making predictions more accurate and reliable than traditional methods.

The primary objective of this project is to develop a robust machine learning model capable of predicting sunspot occurrences. The specific goals include:

Data Collection: Gather historical sunspot data from reliable sources, including observatories and space agencies, spanning multiple solar cycles.

Data Preprocessing: Cleanse and preprocess the data, handling missing values and outliers, ensuring the dataset is ready for analysis.

Feature Selection: Identify relevant features affecting sunspot occurrences. Solar physicists often consider factors such as solar magnetic field strength, solar flares, and geomagnetic indices.

Model Selection: Experiment with various machine learning algorithms, including but not limited to, regression models, decision trees, support vector machines, and neural networks. Evaluate their performance to choose the most suitable one.

Training and Validation: Divide the dataset into training and validation sets. Train the selected model on the training data and validate its accuracy using the validation set.

Hyperparameter Tuning: Fine-tune the model's hyperparameters to optimize its performance, ensuring the best possible predictions.

Evaluation: Evaluate the model's performance using appropriate metrics such as Mean Absolute Error (MAE), Root Mean Square Error (RMSE), or accuracy scores. Compare the results with existing prediction methods to assess the model's superiority.
