The classes of sequences generated by timeand spacerestricted multiple counter machines are compared to the corresponding classes generated by similarly restricted multiple tape Turing machines. Special emphasis is placed on the class of sequences generable by machines which operate in real time. Real-time Turing machines are shown to be strictly more powerful than real-time counter machines. A...

The generation of music lyrics by artificial intelligence (AI) is frequently modeled as a language-targeted sequence-to-sequence task. Formally, if we convert the melody into word sequence, can consider task to be machine translation Traditional tasks involve translating between cross-lingual sequences, whereas and natural language sequences. theme or key words generated are usually limited mee...
