Fine-tuning Convolutional Networks to Classify Dog Breeds

بواسطة: Coursera

Overview

In this 2 hour-long project, you will learn how to approach an image classification task using TensorFlow. You will learn how to effectively preprocess your data to improve model generalizability, as well as build a performant modeling pipeline. Furthermore, you will learn how to accurately evaluate model performance using a confusion matrix; how to interpret results; and how to ask poignant questions about your dataset. Finally, you will fine-tune an existing, state-of-the-art-ready model to improve performance further.

Note: This course works best for learners who are based in the North America region. We’re currently working on providing the same experience in other regions.
