摘要： This application discloses encoding and decoding methods and apparatuses, and relates to the field of artificial intelligence technologies, to improve rate distortion performance of data encoding and decoding methods. The method includes: first obtaining to-be-encoded data, and then inputting the to-be-encoded data into a first encoding network to obtain a target parameter; then constructing a second encoding network based on the target parameter; next inputting the to-be-encoded data into the second encoding network to obtain a first feature; and finally encoding the first feature to obtain an encoded bitstream.
