Deep features are typically the activations from the pre-final layer of a neural network, which act as a condensed numerical representation of the image. : ResNet-18/50 : Good for general tasks and smaller datasets.

: Better for capturing complex, fine-grained details in visually similar images. Ekipa Sara grebenom.zip

To prepare deep features for the dataset within , you should follow a structured pipeline involving data extraction, pre-processing, and feature generation using pre-trained convolutional neural networks (CNNs). 1. Dataset Preparation Deep features are typically the activations from the

Before feeding data into a deep learning model, standardize the input: 1792 for EfficientNet-B4).

: If the dataset is specialized, fine-tune only the last few convolutional blocks while keeping the initial layers frozen.

is the feature vector size (e.g., 1792 for EfficientNet-B4).
