Abstract: Embodiments described herein provide systems and methods for training a sequential recommendation model. Methods include determining a difficulty and quality (DQ) score associated with user behavior sequences from a training dataset. User behavior sequences are sampled during training based on their DQ scores. A meta-extrapolator may also be trained based on user behavior sequences sampled according to DQ score. The meta-extrapolator may be trained with high quality low difficulty sequences. The meta-extrapolator may then be used with an input of high quality high difficulty sequences to generate synthetic user behavior sequences. The synthetic user behavior sequences may be used to augment the training dataset to fine-tune the sequential recommendation model, while continuing to sample user behavior sequences based on DQ score. As the DQ score is based on current model predictions, DQ scores iteratively update during the training process.

Abstract: The present disclosure provides a BIM component creating method, a digital design resource library application method, and a digital design resource library application device. By displaying recommended creation orders in a recommendation interface for a user to select, the user directly selects a recommended operation order in the recommendation interface, which, compared with selecting an order of next step from an order library, has higher selecting efficiency, and can improve the creating efficiency of the BIM component. Besides, in creation and application of a digital design resource library, a plurality of different creating modes are used for implementation. On the basis of improving the BIM component creating efficiency, the efficiency of creating the digital design resource library is further improved. Moreover, through bulk addition of parameters to the BIM component, geometric parameter visualization verification is performed on the BIM component.

Abstract: Embodiments described herein provide a cascade-guided adversarial training method for sequential recommendation models. A system may compute cascade scores for items in a user interaction sequence.

Based on the computed cascade score, the system may perturb item embeddings. The perturbed user interaction sequences with perturbed item embeddings may be used to train a sequential recommendation model.

Abstract: In a rail detection system, a traveling mechanism and a horizontal moving mechanism move a detection device accurately to a position directly above a position to be detected by moving parallel to an extension direction of the rail. A vertical lifting mechanism is provided with the detection device, and can drive the detection device to lift up and down. A aligning mechanism is connected with the detection device, and includes a force-bearing mechanism and a follow-up mechanism. The force-bearing mechanism is configured to generate a force along a direction perpendicular to the extension direction of the rail when being in a non-aligned position. Under the condition of being forced, the follow-up mechanism makes an adaptive adjustment movement along the direction perpendicular to the extension direction of the rail so that the detection device is aligned with a center of the rail.

In a fifth generation (5G)/new radio (NR) system operating in an unlicensed spectrum, when multiple physical uplink shared channel (PUSCH) transmissions are scheduled (e.g., by one or more DCIs), and if LBT operation has failed before the start of a first PUSCH transmission of the multiple PUSCH transmissions, an LBT type and cyclic prefix (CP) extension for a subsequent PUSCH transmission of the multiple PUSCH transmissions is determined. In some examples, the multiple PUSCH transmissions are consecutive PUSCH transmission. Other embodiments may be described and/or claimed.
