Probing Character-level Transformers for the Spanish L-shaped Morphome
Akhilesh Kakolu Ramarao, Kevin Tang, Wiebke Petersen +1
When a transformer learns an irregular morphological pattern, what has it learned? Our test case is the Spanish \emph{L-shaped morphome}, a complex irregular pattern in which the v…
Transformers over-extend what humans underlearn: the case of Spanish L-shaped morphome
Akhilesh Kakolu Ramarao, Kevin Tang, Dinah Baer-Henney
The cognitive reality of irregular morphological patterns has been debated for decades: do speakers extend them to novel forms, or are they lexical artifacts? A neural network trai…
Character-aware Transformers Learn an Irregular Morphological Pattern Yet None Generalize Like Humans
Akhilesh Kakolu Ramarao, Kevin Tang, Dinah Baer-Henney
Whether neural networks can serve as cognitive models of morphological learning remains an open question. Recent work has shown that encoder-decoder models can acquire irregular pa…
Frequency matters: Modeling irregular morphological patterns in Spanish with Transformers
Akhilesh Kakolu Ramarao, Kevin Tang, Dinah Baer-Henney
Over the past decade, various studies have addressed how speakers solve the so-called `The Paradigm Cell Filling Problem' (PCFP) \citep{ackerman2009parts} across different language…
