Abstract: Disclosed herein is an apparatus for receiving data from memory. The apparatus receives a data signal and a clock signal output from memory and includes a Decision Feedback Equalizer (DFE) including two or more differential signal path units configured to determine and output an output value corresponding to the data signal. Each of the two or more differential signal path units may determine a current output value by reflecting a previous output value fed back from a different one of the two or more differential signal path units in such a way that they operate at different clocks, and may include an offset control unit configured to adjust an offset at an input stage and a feedback control unit configured to change a load of an output stage using the previous output value fed back from the different one of the two or more differential signal path units.

Abstract: Provided are a multitask learning apparatus and method for improving learning performance of heterogeneous small datasets. The multitask learning apparatus includes a first layer configured to generate feature vectors by projecting training data pairs generated from different tasks to one feature space, a second layer configured to extract a common feature from the projected feature vectors, and a third layer configured to draw each individual inference from the extracted common feature. Here, the first layer and the third layer are task-specific layers, and the second layer is a layer shared between tasks. The first layer, the second layer, and the third layer perform forward propagation in one artificial neural network.

Abstract: Disclosed herein are a method, an apparatus, and a storage medium for image encoding/decoding using geometric partitioning. A target block may be geometrically partitioned, and multiple partitioned regions may be generated from geometric partitioning. Each partitioned region may have a non-square and a non-rectangular shape. Different prediction schemes may be applied to different partitioned regions. The different prediction schemes for multiple partitioned regions may be signaled as explicit information, and may be derived using information about a coding parameter for the target block or the like.
