Abstract: Provided are techniques for identifying and correcting model focus drift during model training. A model is trained using an original dataset with data, and the is classified into clusters. A representation is assigned to each of the clusters. A first visualization dashboard with visualizations is generated, where each visualization represents a first data distribution of an associated cluster using the representation assigned to that cluster. The model is fine-tuned using a fine-tune dataset. A second visualization dashboard is generated by updating each visualization, where each visualization represents a second data distribution of the associated cluster. It is determined that a cluster of the clusters has focus drift based on changes between the first data distribution and the second data distribution. The focus drift is corrected by: adding the data of the cluster to the fine-tune dataset to form a combined dataset and fine-tuning the model using the combined dataset.

Abstract: A semiconductor device structure is provided. The semiconductor device structure includes a chip structure including a substrate and a wiring structure over a first surface of the substrate. The semiconductor device structure includes a first seed layer over the wiring structure, a first inner wall of the first enlarged portion, and a second inner wall of the neck portion. The semiconductor device structure includes a second seed layer over a second surface of the substrate, a third inner wall of the second enlarged portion, and the first seed layer over the second inner wall of the neck portion. The second seed layer is in direct contact with the first seed layer.

Abstract: An electronic signal adapter module of a flash memory card is disclosed. A seat serves for storing one or a plurality of flash memory cards of different specifications. These flash memory cards use the same storage space in the seat and are inserted into the space at different timings. At least one substrate is combined with the seat. After the flash memory card is inserted into the seat, the substrate transfers signals between the flash memory cards and a reading and writing device. The feature of the present invention is that one end of the seat for being inserted by a flash memory card has two wings. Each wing is arranged with an elastic reed. By the reeds of the two wings, the flash memory card inserted into the seat generates an elastic force so that the pins on the flash memory card have preferred contact effect with the conductive elements of the substrates.
