1. A communication speed prediction apparatus for predicting a future communication speed between a first communication apparatus and a second communication apparatus that is to move relative to the first communication apparatus,
the communication speed prediction apparatus comprising:
at least one processor; and
at least one memory storing instructions executed by the at least one processor to:
predict a future relative positional relationship between the first and second communication apparatuses;
predict the future communication speed between the first and second communication apparatuses by using a predicted result of the future relative positional relationship and a prediction model that is for predicting the future communication speed between the first and second communication apparatuses based on the relative positional relationship between the first and second communication apparatuses;
extract, from an information source that includes a plurality of sample information in each of which a past position information relating to a past relative positional relationship between the first and second communication apparatuses is associated with a past speed information relating to a past communication speed between the first and second communication apparatuses, at least one sample information as a training information for training the prediction model;
train a parameter of the prediction model by using the training information;
update, by using the trained parameter, the prediction model used to predict the future communication speed between the first and second communication apparatuses; and
change, based on at least one of a state of the communication speed prediction apparatus and a state of the first and second communication apparatuses, an update frequency by which the prediction model is updated.
