Overview
Causal inference in machine learning is a rapidly evolving field that enhances the capabilities of ML models by enabling them to identify and understand causal relationships between variables. This overview explores the key aspects of a Causal Inference ML Engineer's role.
Core Objectives
The primary goal of causal inference in machine learning is to improve the accuracy and interpretability of models by capturing causal relationships rather than just correlations. This is crucial for making informed decisions and predicting the outcomes of interventions or changes in variables.
