Uszkoreit, Neil Houlsby. ( With the transformers library, you can use the image-classification pipeline to infer with image classification models. In vision, attention is either applied in conjunction with You can also provide a top_k parameter which determines how many results it should return. In addition, we thank to National Center for Highperformance Computing (NCHC) for providing computational and storage resources. This includes the use of Multi-Head Attention, Scaled Dot-Product Attention and other architectural features seen in the Transformer architecture traditionally used for NLP.
