Efficient and lightweight CNN architecture for mobile and edge devices.
MobileNetV3 is a series of convolutional neural network architectures designed for mobile and edge devices, focusing on maximizing accuracy while minimizing computational cost and model size. Based on the 'Searching for MobileNetV3' paper, these models leverage a combination of hardware-aware network architecture search (NAS) and network design. The architecture includes inverted residual blocks with linear bottlenecks and squeeze-and-excitation modules for efficient feature extraction. MobileNetV3 comes in two variants: Large and Small, catering to different resource constraints. These models are implemented within PyTorch's torchvision library, offering pre-trained weights for easy integration. They facilitate tasks such as image classification, object detection, and semantic segmentation, with optimized performance on resource-constrained devices. The builders instantiate a MobileNetV3 model from torchvision.models.mobilenetv3.MobileNetV3 base class.

Install PyTorch and torchvision.
Import the desired MobileNetV3 model (e.g., `mobilenet_v3_large`) from `torchvision.models.mobilenetv3`.
Load pre-trained weights using `weights='DEFAULT'` for state-of-the-art performance or `weights=None` for training from scratch.
Preprocess input images using `torchvision.transforms` to normalize and resize them to the expected input size (typically 224x224).
Pass the preprocessed image tensor through the model to obtain predictions.
Apply a softmax function to the output to get class probabilities.
Evaluate model performance using standard metrics like accuracy, precision, and recall.
