Simplifying Translations for Children: Iterative Simplification Considering Age of Acquisition with LLMs

2024

In recent years, neural machine translation (NMT) has been widely used in everyday life.However, the current NMT lacks a mechanism to adjust the difficulty level of translations to match the user's language level.Additionally, due to …

Controlling Output Length in Neural Encoder-Decoders

2016

Neural encoder-decoder models have shown great success in many sequence generation tasks. However, previous work has not investigated situations in which we would like to control the length of encoder-decoder outputs. This capability is crucial …
