📖 Deep learning is a powerful technique for machine learning that can be used to solve a wide variety of problems. Deep learning models are typically composed of multiple layers of artificial neurons, which are connected in a hierarchical fashion. Each layer learns to extract different features from the input data, and the final layer learns to make predictions based on the features extracted by the previous layers.

8.5 Judea Pearl
📖 Causality is a fundamental concept in machine learning. Causality refers to the relationship between a cause and its effect. Machine learning algorithms can be used to learn causal relationships from data. This knowledge can be used to make better predictions and decisions.
“Causality is not the same as correlation. Just because two events are correlated does not mean that one causes the other.”
— Judea Pearl, Causality: Models, Reasoning, and Inference
For example, the fact that ice cream sales and drowning deaths are both correlated with temperature does not mean that eating ice cream causes drowning.”
“The presence of a common cause can lead to spurious correlations.”
— Judea Pearl, Causality: Models, Reasoning, and Inference
For example, the fact that both smoking and lung cancer are correlated with poverty does not mean that smoking causes poverty.”
“It is important to consider the temporal order of events when inferring causality.”
— Judea Pearl, Causality: Models, Reasoning, and Inference
For example, the fact that a patient takes a drug and then gets better does not necessarily mean that the drug caused the improvement.”

Deep learning models have a large number of parameters, which can make them difficult to train. The training process can be slow and unstable, and it can be difficult to find the right hyperparameters for the model.
“Deep learning models can be brittle.”
— Gary Marcus, Deep Learning: A Critical Appraisal
Deep learning models are often trained on large datasets, and they can be sensitive to changes in the data. If the data is changed, the model may no longer perform well. This can make it difficult to use deep learning models in real-world applications, where the data is often changing.
“It is important to understand the limitations of deep learning before using it to solve a problem.”
