Sparse coding is a method in machine learning and neuroscience that represents input data as a combination of a small number of active elements from an overcomplete basis set, enabling efficient data representation and feature extraction. This approach mimics the way biological systems process information, promoting interpretability and robustness in models by focusing on the most informative components of the data.

Machine learning is a subset of artificial intelligence that involves the use of algorithms and statistical models to enable computers to improve their performance on a task through experience. It leverages data to train models that can make predictions or decisions without being explicitly programmed for specific tasks.

Biological systems are complex networks of biologically relevant entities that interact to form the structure and function of living organisms, ranging from molecular systems within cells to entire ecosystems. Understanding these systems requires a multidisciplinary approach, integrating biology, chemistry, physics, and computational sciences to model and analyze their dynamic behaviors and interactions.

Interpretability is the degree to which a human can understand the cause of a decision made by a model or system, crucial for trust and accountability in AI and machine learning applications. It enables stakeholders to validate models, ensure fairness, and comply with regulatory standards by providing insights into how inputs are transformed into outputs.
