What is an example of a many-to-many sequence modeling task?

Question

BlackTom AI · Accepted Answer

To evaluate the options, we first recall what a many-to-many sequence modeling task involves: the model processes a sequence as input and produces a (potentially different) sequence as output, with a temporal alignment that often spans the entire input and output, such as translating sentences from one language to another.
Option 1: 'Image classification' — This is typically a many-to-one (or sometimes one-to-one) task: a single input image yields a single label. It does not involve generating a sequence of outputs over time, so it is not a many-to-many sequence task.
Option 2: 'Language translation' — Involves reading a source sentence and generating a target sentence, word by word, over time. This clearly fits the many-to-many sequence model pattern, where the input and output are sequences and there is a sequential dependence between outputs.
Option 3: 'Sentiment analysis' — Usually yields a single sentiment label for an entire input text, which is again a many-to-one (or one-to-one) mapping rather than a sequence-to-sequence generation. It does not require producing a full output sequence.
In summary, the task that embodies generating a sequence output from a sequence input, aligning across time, is language translation, whereas the other options map to non-sequence or single-output tasks.
