Key techniques in unsupervised learning include: Clustering (K-means) K-means is a clustering algorithm that groups data points into clusters based on their similarities. These networks can learn from large volumes of data and are particularly effective in handling tasks such as image recognition and natural language processing.

Clustering and dimensionality reduction are common tasks in unSupervised Learning. For example, clustering algorithms can group customers by purchasing behaviour, even if the group labels are not predefined. customer segmentation), clustering algorithms like K-means or hierarchical clustering might be appropriate.

Quantitative evaluation We utilize 2018–2020 season data for model training and validation, and 2021 season data for model evaluation. We perform a five-fold cross-validation to select the best model during training, and perform hyperparameter optimization to select the best settings on multiple model architecture and training parameters.

Clustering: An unsupervised Machine Learning technique that groups similar data points based on their inherent similarities. Cross-Validation: A model evaluation technique that assesses how well a model will generalise to an independent dataset. NLP enables machines to understand and interpret text and speech.

Projecting data into two or three dimensions reveals hidden structures and clusters, particularly in large, unstructured datasets. Feature encoding bridges this gap by converting categories into numerical representations that models can process effectively. Adopt an Iterative Approach Feature extraction is rarely a one-time process.
