WebFeb 9, 2024 · While searching related literature, I was able to read the papers to develop more advanced positional encoding. In particular, I found that positional encoding in Transformer can be beautifully extended to represent the time (generalization to the continuous space) and positions in a graph (generalization to the irregular structure). WebApr 14, 2024 · Luckily, positional encoding in Transformer is able to effectively capture relative positions , which are similar to time spans for timestamps. Since time series are essentially timestamp sequences, we extend positional encoding to temporal encoding, which is defined in complex vector spaces.
