In an example embodiment, the method for processing pieces of event information in a collection server, includes: checking whether pieces of target event information have been obtained from a message queue in which the pieces of event information have been stored while being sorted; when the pieces of target event information are checked to be obtained, converting at least some of the obtained pieces of target event information so as to correspond to a schema of a first database and recording the converted pieces of target event information in the first database; and generating a notification indicating that the pieces of target event information are obtained.

Abstract: Provided is an electronic apparatus and a method of managing feature information performed by the electronic apparatus, the method including the electronic apparatus receiving a request to store feature information in a database, based on at least some of a feature quantity, attributes of the feature information, a calculation method of the feature information and sources of the feature information, the electronic apparatus storing the feature information in one of a first database in which data for inference of a machine learning model is stored and a second database in which data for training the machine learning model is stored, and the electronic apparatus synchronizing the feature information from one of the first database and the second database in which the feature information is stored to the other database.

Abstract: Systems and methods for domain generalization configured in accordance with some embodiments of the invention are illustrated. One embodiment includes a method for domain generalization of a machine learning model. The method sets a parameter of a first model and a parameter of a second model based on a pre-trained model. The method learns the second model by performing a predetermined task on a source domain. The method estimates an unobservable gradient for model updates on an unseen domain based on: the parameter of the first model, and the parameter of the second model. The method updates the first model based on the estimated unobservable gradient.

Abstract: Disclosed is a method for detecting abusing video information in an electronic device, the method including obtaining first information associated with a user participating in a broadcast and second information associated with a content of the broadcast, determining, based on the second information and a first list of one or more types of abuse, third information about whether the second information corresponds to one of the one or more types of abuse, providing, based on the third information, a service server involved in provision of the broadcast with the first information, the second information and the third information, and providing, based on the third information, a verification server associated with user sanctions with the first information and the second information.

Abstract: Provided is a method for providing information by a recommendation server, the method including obtaining first information regarding a user and second information regarding broadcasts from a service server regarding broadcasts, receiving a request by the user for a recommended broadcast list from the service server, identifying, in response to the request, third information about a live-streaming broadcast based on the second information, and providing recommended broadcast list information based on the first information and the third information.

Abstract: Provided is a video mediating apparatus between a host terminal and a user terminal, and a method and computer readable recording medium thereof. A video mediation method of the present disclosure includes, between a host terminal and at least one user terminal, establishing a main session for mediating a main video including a video transmitted from the host terminal to the at least one user terminal, mediating the main video through the main session, identifying a user terminal set selected among the at least one user terminal, establishing a sub-session for mediating a sub-video including a video transmitted from the host terminal to the user terminal set between the host terminal and the user terminal set while maintaining the main session, and mediating the sub-video through the sub-session while maintaining the main session.

Abstract: A method for training a training dynamics prediction model comprising acquiring classification information on training data included in a first dataset based on a classification model, acquiring target training dynamics information based on the classification information and a set of one or more classification information acquired based on the classification model in one or more previous epochs, acquiring predictive training dynamics information on the training data based on the training dynamics prediction model, and training the training dynamics prediction model based on the target training dynamics information and the predictive training dynamics information is disclosed.

Abstract: A report evaluation method of a report evaluation device may include receiving a report from at least one client terminal, determining a category of the received report, identifying a learning model corresponding to the category, evaluating a reliability of the report through the learning model, and generating and outputting information on the reliability.

Abstract: A mediating method may include: preparing at least two lists that respectively correspond to different values of a specific feature and that each of which includes at least one item; receiving first information about a first terminal or a user of the first terminal from the first terminal; deriving a value corresponding to the specific feature using the received first information; selecting a first list from among the at least two lists using the derived value; determining whether a first item matching the user of the first terminal is present in the at least one item included in the first list using the first information; and when it is determined that the first item is present in the first list, transmitting second information corresponding to the first item to the first terminal, or transmitting third information corresponding to the first terminal to a second terminal corresponding to the first item.

Abstract: A terminal may include a display that is divided into at least two areas, when a real time broadcasting, where a user of the terminal is a host, starts through a broadcasting channel, and of which one area of the at least two areas is allocated to the host; an input/output interface that receives a voice of the host; a communication interface that receives one item selected of at least one or more items and a certain text from a terminal of a certain guest, of at least one or more guests who entered the broadcasting channel; and a processor that generates a voice message converted from the certain text into the voice of the host or a voice of the certain guest.
