MACHINE LEARNING METHOD AND INFORMATION PROCESSING APPARATUS

An information processing apparatus acquires word dictionary data in which strings each representing one of multiple words are mapped to codes each identifying one of the multiple words. The information processing apparatus converts text data into encoded text data by encoding words included in the text data based on the word dictionary data. The information processing apparatus initializes parameters included in a machine learning model based on the word dictionary data and the encoded text data. The information processing apparatus runs a learning process to train, based on the encoded text data, the machine learning model from which the word dictionary data has been detached after the initialization.
