Abstract: A zero padding apparatus and method for variable length signaling information are disclosed. A zero padding apparatus according to an embodiment of the present invention includes a processor configured to generate a LDPC information bit string by deciding a number of groups whose all bits are to be filled with 0 using a difference between a length of the LDPC information bit string and a length of a BCH-encoded bit string, selecting the groups using a shortening pattern order to fill all the bits of the groups with 0, and filling at least a part of remaining groups, which are not filled with 0, with the BCH-encoded bit string; and memory configured to provide the LDPC information bit string to an LDPC encoder.

Abstract: An image encoding/decoding method and apparatus are disclosed. The image decoding method includes acquiring prediction mode information of a current block from a bitstream, decoding an intra block copy prediction mode of the current block using the prediction mode information of the current block, and reconstructing the current block based on the intra block copy prediction mode. The intra block copy prediction mode is at least one of a block copy based SKIP mode, a block copy based MERGE mode or a block copy based AMVP mode.

Abstract: Provided is an exploration method based on reward decomposition in multi-agent reinforcement learning. The exploration method includes: generating a positive reward estimation model through neural network training based on training data including states of all agents, actions of all the agents, and a global reward true value; generating, for each of the agents, a first individual utility function based on the global reward true value and generating a second individual utility function using the positive reward estimation model; and determining an action of each of the agents using the first individual utility function and the second individual utility function based on the state of each of the agents.

Abstract: A method and apparatus for block propagation in a blockchain platform. Where multiple nodes establish a peer through a peer-to-peer network and maintain the same blockchain, a node stores information of a first peer transmitted a first forwarding message in a first storage when receiving, from the first peer, which is a node on the network, the first forwarding message including a first portion associated with a block. The node transmits a second forwarding message including the first portion to a second peer that is a node on the network. The node transmits a first request message to the first peer based on information in the first storage, the first request message requesting a second portion associated with the block and corresponding to the first portion. The node receives a third forwarding message including the second portion corresponding to the first request message from the first peer.
