Что такое temporal modeling и зачем нужен временной вход?

Temporal modeling is an approach in machine learning and artificial intelligence that considers the temporal dynamics of data. It is especially important when working with sequences, videos, time series, and 3D data, where information changes over time.

Temporal input is needed so that the model can analyze not only individual static frames or objects but also their changes, movement, and development of events. This allows for a better understanding of context and predicting future states.

For example, in computer vision for video, temporal modeling helps recognize actions or events by analyzing a sequence of frames rather than a single frame alone. In 3D modeling, temporal input allows accounting for changes in shape or position of an object over time.

Recurrent neural networks (RNN), LSTM, GRU, or transformers are often used for temporal modeling, as they are capable of processing sequences and remembering context.
