Witryna29 cze 2024 · I want to build a CNN model that takes additional input data besides the image at a certain layer. To do that, I plan to use a standard CNN model, take one of its last FC layers, concatenate it with the additional input data and add FC layers processing both inputs. The code I need would be something like: additional_data_dim = 100 … Witryna14 mar 2024 · Specifically, the Vision Transformer is a model for image classification that views images as sequences of smaller patches. As a preprocessing step, we split an image of, for example, pixels into 9 patches. Each of those patches is considered to be a “word”/“token”, and projected to a feature space. high ranger motorcycle pants https://payway123.com
