Abstract: The present invention relates to a multi-modality system for recommending multiple items using an interaction and a method of operating the same. The multi-modality system includes an interaction data preprocessing module that preprocesses an interaction data set and converts the preprocessed interaction data set into interaction training data; an item data preprocessing module that preprocesses item information data and converts the preprocessed item information data into item training data; and a learning module that includes a neural network model that is trained using the interaction training data and the item training data and outputs a result including a set of recommended items using a conversation context with a user as input.

Abstract: The present invention relates to a hybrid transmission using an engine and two electric motors/generators together, wherein a planetary gear device comprising double planet gears, two sun gears and a ring gear, as a power splitter is used, and in addition, to a hybrid transmission in which one or more clutches and/or one or more brakes are combined to select a mechanical shift mode other than a hybrid mode and an electric drive mode.

Abstract: A three mode stepless speed changing device is disclosed. The speed changing device of this invention maintains the operational performance expected by a four mode stepless speed changing device. Because one clutch, two gears and their associated elements, which are necessarily provided in the four mode device for performing the third mode of the four modes, are removed from the three mode device of this invention, the device of this invention has a simple construction. The device of this invention is also free from pressurized oil passages, which are necessary for performing the third mode of the four mode device. In this regard, the speed changing device of this invention is easily produced and assembled at low cost.
