Why is my validation loss lower than my training loss? - PyImageSearch

In this tutorial, you will learn the three primary reasons your validation loss may be lower than your training loss when training your own custom deep neural networks. I first became interested in studying machine learning and neural networks in late high school. Back then there weren't many accessible machine learning libraries -- and there certainly was no scikit-learn. Every school day at 2:35 PM I would leave high school, hop on the bus home, and within 15 minutes I would be in front of my laptop, studying machine learning, and attempting to implement various algorithms by hand. I rarely stopped for a break, more than occasionally skipping dinner just so I could keep working and studying late into the night.
