: Using a second ML model to decide whether to act on the primary model's prediction, effectively acting as a "size" or "filter" layer to reduce false positives. Feature Engineering :

: Techniques like Mean Decrease Impurity (MDI) and Mean Decrease Accuracy (MDA) are used to identify which variables truly drive market movements. Validation & Backtesting : Advances in Financial Machine Learning

: Traditional integer differentiation (like computing returns) removes "memory" from data. Fractional differentiation aims to achieve stationarity while preserving as much memory as possible. : Using a second ML model to decide

: Moving away from standard time-based bars to Tick , Volume , or Dollar bars helps synchronized data with market activity levels.

The field of (FinML) has moved beyond simple predictive models, largely influenced by Marcos López de Prado's seminal work, Advances in Financial Machine Learning . This discipline addresses the unique challenges of financial data, such as low signal-to-noise ratios and non-IID (Independent and Identically Distributed) properties. Core Methodologies in Modern FinML
