2. What is Robust Machine Learning and Why is it Important?

Noise: The data may contain errors, outliers, or missing values that can reduce the quality and reliability of the data.
Adversarial attacks: The data or the model may be intentionally manipulated by malicious agents who want to deceive or sabotage the machine learning system.
Distribution shifts: The data or the environment may change over time, making the machine learning model outdated or inaccurate.

Robust machine learning methods aim to address these challenges by using various techniques, such as:

Data preprocessing: The data may be cleaned, filtered, or augmented to reduce the noise and improve the quality of the data.
Model regularization: The model may be constrained, penalized, or modified to prevent overfitting and improve the generalization of the model.
Model adaptation: The model may be updated, fine-tuned, or transferred to adapt to the changing data or environment.

Robust machine learning is important because it can enhance the performance and reliability of the machine learning systems, especially in critical domains where the consequences of failure can be severe, such as healthcare, security, or finance. Robust machine learning can also increase the trust and confidence of the users and stakeholders who interact with the machine learning systems, as they can expect consistent and accurate results.
