What was the issue Llion Jones faced when working on the Wiki Reading project?
-The issue was that the models at the time were word-level and struggled with out-of-vocabulary words, which led Llion Jones to explore character-level modeling as a solution.
How did Llion Jones address the problem of out-of-vocabulary words in the Wiki Reading project?
-He used pre-trained language models to handle out-of-vocabulary words more effectively, which involved freezing a pre-trained RNN language model and training another recurrent neural network on top of it.
What is the advantage of character-level language models over word-level models?
-Character-level language models can handle any vocabulary, including rare and new words, since they process text at the character level, thus avoiding out-of-vocabulary issues.
What was Llion Jones' role in improving Google Maps' pronunciations for place names in Japan?
-Llion Jones worked on a character-level Transformer model that analyzed place names written in kanji and the surrounding context to improve the pronunciation accuracy in Google Maps.
Why is Llion Jones interested in exploring character-level language modeling further?
-Llion Jones is interested in character-level language modeling because it offers a more natural and flexible approach to language processing, especially for languages like Japanese that have complex morphological structures.
What is the potential future of character-level language models according to Llion Jones?
-Llion Jones believes that character-level language models will eventually become the standard due to their simplicity and effectiveness, and he is also open to the possibility of moving directly to audio-level language models if computational resources allow.
