People also ask
How does Time2Vec work?
We feed Time2Vec as an input to the model (or to some gate in the model) instead of adding it to other vector representations. Unlike positional encoding, we show in our experiments that learning the frequencies and phase-shifts of sine functions in Time2Vec result in better performance compared to fixing them.
Is time series analysis hard?
Real-world time series data often contain noise that can make similarity detection difficult. Noise can introduce spurious dissimilarities, making it harder to match series effectively. Smoothing out noise focuses the similarity measure on the essential features of the data, improving both accuracy and robustness.

What is the time series problem?
In time series problems, we expect observations close to each other in time to be more similar than observations far away, after accounting for seasonality. For example, the weather today is usually more similar to the weather tomorrow than the weather a month from now.
