TensorFlow image multi-label classification example
Next, we will explain an example of image multi-label classification based on TensorFlow from scratch. Here, we will take the image verification code as an example. When we visit a website, we often encounter image verification codes. The main purpose of image CAPTCHA is to distinguish between bots and humans and to keep bots out. […]
