👉 In the context of natural language processing and machine learning, an "upsiloid" is a type of entity recognition model. This concept is often used in image classification tasks where the input data consists of images or video frames, and the goal is to classify them into one of predefined categories (e.g., animals, people, etc.). An upsiloid is a deep neural network architecture that combines several convolutional layers with skip connections between them. These layers are designed to identify objects in an
