Choosing just one best candidate might be suitable for the current time step, but when we construct the full sentence, it may be a sub-optimal choice. WebJun 3, 2024 · A simple approximation is to use a greedy search that selects the most likely word at each step in the output sequence. This approach has the benefit that it is very fast, but the quality of the final output sequences may be far from optimal. We can demonstrate the greedy search approach to decoding with a small contrived example in Python.
