Answer

Automatic feature extraction and representation learning through multiple layers of abstraction. Explanation 1. Identify the unique characteristic Deep learning is characterized by its ability to automatically extract features from raw data through multiple layers of abstraction, which traditional machine learning typically does not do. Traditional machine learning often requires manual feature extraction and selection before model training. 2. Compare with traditional machine learning In traditional machine learning, feature engineering is a crucial step where domain knowledge is used to manually select and transform input variables into a format suitable for the model. Deep learning models, particularly neural networks, can learn these representations directly from the data without explicit programming. 3. Summarize the key difference The key difference is that deep learning models can perform automatic feature extraction and representation learning, which reduces the need for manual intervention in the preprocessing stage.
