A researcher is training a sequence-processing model and observes that while it correctly identifies the meaning of individual words, it consistently fails on tasks where word order is crucial. For example, it treats 'dog bites man' and 'man bites dog' as having the same overall meaning. The researcher suspects an issue in how the initial input vectors are constructed for the model. What is the most probable cause of this issue?

Constructing an Input Vector for a Sequence Model

Calculating a Combined Input Vector
