Apparatus for predicting speed of vehicle and method thereof

A method of predicting a speed of a vehicle, the method comprising:

• storing, by a storage, a transformer model which completes learning;
• and
• predicting, by a controller, the speed of the vehicle based on the transformer model;
• wherein the predicting of the speed of the vehicle includes:
• inputting, by the controller, feature information to an encoder of the transformer model by extracting the feature information about a state of the vehicle from past driving information of the vehicle;
• and
• inputting, by the controller, feature information to a decoder of the transformer model by extracting the feature information about the state of the vehicle from future driving information of the vehicle.
