Intelligent Mobile Projects with TensorFlow

Overview of this book

As a developer, you always need to keep an eye out and be ready for what will be trending soon, while also focusing on what's trending currently. So, what's better than learning about the integration of the best of both worlds, the present and the future? Artificial Intelligence (AI) is widely regarded as the next big thing after mobile, and Google's TensorFlow is the leading open source machine learning framework, the hottest branch of AI. This book covers more than 10 complete iOS, Android, and Raspberry Pi apps powered by TensorFlow and built from scratch, running all kinds of cool TensorFlow models offline on-device: from computer vision, speech and language processing to generative adversarial networks and AlphaZero-like deep reinforcement learning. You’ll learn how to use or retrain existing TensorFlow models, build your own models, and develop intelligent mobile apps running those TensorFlow models. You'll learn how to quickly build such apps with step-by-step tutorials and how to avoid many pitfalls in the process with lots of hard-earned troubleshooting tips.

Building and training GAN models with TensorFlow

In general, a GAN model has two neural networks: G for the generator and D for the discriminator. x is some real data input from the training set, and z is random input noise. During the training, D(x) is the probability of x being real and D tries to make D(x) close to 1; G(z) is the generated output with the random input z, and D tries to make D(G(z)) close to 0, but at the same time, G tries to make D(G(z)) close to 1. Now, let's first see how we can build a basic GAN model in TensorFlow and Python that can write or generate handwritten digits.
