## Dimensionality Reduction

Dimensionality reduction is the process of reducing the number of input variables in a predictive model while retaining the most important information. In complex derivative markets, traders often deal with hundreds of potential indicators, from order flow data to macroeconomic metrics.

Many of these variables may be redundant or contain high levels of noise, which can lead to overfitting if all are included. Techniques like Principal Component Analysis help identify the core drivers of market movement, simplifying the model architecture.

This reduction improves computational efficiency and makes the model less prone to capturing spurious correlations. By focusing only on the most impactful features, the model becomes more robust to the inherent noise of digital asset markets.

It allows for a clearer view of the essential relationships governing price discovery.
