How to Select the Right Computer Vision Model Architecture
The success of your machine learning model starts well before you ever begin training. Ensuring you have representative images, high quality labels, appropriate preprocessing steps, and augmentations to guard against overfitting all affect deep learning model performance well before you begin training.
And this is where Roboflow Organize comes in

You Might Be Resizing Your Images Incorrectly
Resizing images is a critical preprocessing step in computer vision.
Principally, our machine learning models [https://models.roboflow.ai] train
faster on smaller images. An input image that is twice as large requires our
network to learn from four times as many pixels — and that time adds up.
Moreover, many
