You now have a working command of both paradigms of morphological computation.
- Morphological analysis maps surface words to candidate (lemma, feature bundle) analyses, and generation maps analyses to licensed forms. Either direction can be relational rather than one-to-one; weights and context help rank alternatives.
- Finite-state transducers model morphotactics and morphophonology as regular relations. They are closed under composition and inversion, so one encoded relation can support analysis and generation. Their guarantees are exact relative to the grammar. Two-level constraints describe lexical–surface correspondences in parallel rather than as an ordered cascade.
- Weighted FSTs rank competing analyses with negative log probabilities and pick the minimum-weight path, a transducer-relative of Viterbi decoding.
- Neural sequence-to-sequence models learn inflection from character-level parallel data. Attention or explicit copy mechanisms can help preserve stems, but generalization must be measured on held-out data.
- The paradigms are complementary: rule systems offer grammar-relative guarantees and interpretability, neural systems learn coverage from data, and hybrid designs can combine candidates, learned scores, and hard constraints.
