The chip layout encoder training method comprises: acquiring a sample chip layout and an initial encoder (201); performing geometric transformation on the sample chip layout to obtain at least one reference chip layout (202); extracting sample layout features of the sample chip layout and reference layout features of the reference chip layouts by using the initial encoder (203); and training the initial encoder on the basis of the sample layout features and the reference layout features to obtain a trained encoder (204). By using the methods and the devices, for the chip layouts before and after geometric transformation, a chip layout encoder can output similar layout features, such that the chip layout encoder focuses on extracting a layout feature capable of distinguishing a chip layout type, thereby facilitating subsequent improvement of the accuracy of a clustering result when the chip layout is clustered on the basis of the layout feature.

Abstract

Disclosed in the present application are a vehicle control method and apparatus, and a device and a storage medium. The embodiments of the present application can be applied to the field of autonomous driving or the field of assisted driving. The vehicle control method provided in the embodiments of the present application implements sliced sensing. For any road section, a road image set of the road section under different environmental conditions may be constructed, and a sensing model of the road section under the different environmental conditions is trained according to the road image set of the road section under the different environmental conditions, so as to form a sensing model library. In this way, during a travelling process, a vehicle to be controlled can dynamically call, according to a road section to be travelled on the way and a target environmental condition when said vehicle is in the corresponding road section to be travelled, the most adapted target sensing model from a sensing model library to perform sensing. Since different sensing models are trained for different road sections and different environmental conditions, all possible situations during a vehicle travelling process can be accurately sensed, thereby ensuring the driving safety.
