37. Overfitting
This occurs when a model learns the detail and noise in the training data to the extent that it negatively impacts the performance of the model on new data. This means the model is too complex, capturing patterns that do not generalize to new data.
38. Underfitting
Underfitting occurs when a machine learning model is too simple to capture the underlying structure of the data. A model that underfits is unable to perform well on the training data or on unseen data.

42. Attention Mechanism
In neural networks, particularly those involved in natural language processing, the attention mechanism allows models to focus on specific parts of the input for generating the output, similar to how humans pay attention to certain parts of a visual scene or listening.
43. Autoencoder
A type of neural network used to learn efficient codings of unlabeled data (unsupervised learning). The aim is to learn a representation (encoding) for a set of data, typically for dimensionality reduction, by training the network to ignore signal "noise."
44. Loss Function
A loss function is used to optimize a machine learning algorithm. It's a method of evaluating how well specific algorithm models the given data. If predictions deviate from actual results, loss function would churn out a high value.
