Abstract: Provided in the present disclosure are a multi-layer multi-pass welding method and apparatus, and a processor and a welding system. The method includes: before welding an ith weld layer of a weld seam, determining a first welding strategy for the ith weld layer according to a first weld seam image, welding paths of the weld passes, and welding operation parameters, with i?2 and i being an integer; according to the first welding strategy, controlling a welding device to weld at least one weld pass of the ith weld layer; according to a second weld seam image, adjusting the first welding strategy corresponding to a current weld pass of the ith weld layer, so as to obtain a second welding strategy, and according to the second welding strategy, controlling the welding device to weld the current weld pass.

Abstract: Techniques are generally described for interactive image retrieval using visual semantic matching. Image data and text data are encoded into a single shared visual semantic embedding space. A prediction model is trained using reference inputs, target outputs, and modification text describing changes to the reference inputs to obtain the target outputs. The prediction model can be used to perform image-to-text, text-to-image, and interactive retrieval.
