Sequence models are best used for which of the following types of problems?

Sequence models are particularly well-suited for problems involving sequentially ordered data points or events because they are designed to handle data that is organized in a specific order and often has temporal dependencies. This makes them ideal for applications such as natural language processing, time series forecasting, and speech recognition, where the order of the data is crucial for understanding context and meaning.

In these scenarios, the model can learn patterns and relationships that are time-dependent or context-sensitive, which is essential in tasks where the sequence of inputs significantly influences the output. For instance, in language processing, the meaning of a word can change depending on the words that precede it in a sentence.

Other options presented do not align with the capabilities of sequence models. For example, image classification and object recognition typically rely on convolutional neural networks that process spatial features rather than sequential information. Static data analysis generally deals with non-sequential datasets, and non-linear regression problems focus on predicting outcomes without the sequential aspect, which does not require the temporal or ordered analysis that sequence models provide.
