TensorFlow Machine Learning Projects

By: Ankit Jain, Amita Kapoor

Overview of this book

TensorFlow has transformed the way machine learning is perceived. TensorFlow Machine Learning Projects teaches you how to exploit the benefits—simplicity, efficiency, and flexibility—of using TensorFlow in various real-world projects. With the help of this book, you’ll not only learn how to build advanced projects using different datasets but also be able to tackle common challenges using a range of libraries from the TensorFlow ecosystem. To start with, you’ll get to grips with using TensorFlow for machine learning projects; you’ll explore a wide range of projects using TensorForest and TensorBoard for detecting exoplanets, TensorFlow.js for sentiment analysis, and TensorFlow Lite for digit classification. As you make your way through the book, you’ll build projects in various real-world domains, incorporating natural language processing (NLP), the Gaussian process, autoencoders, recommender systems, and Bayesian neural networks, along with trending areas such as Generative Adversarial Networks (GANs), capsule networks, and reinforcement learning. You’ll learn how to use the TensorFlow on Spark API and GPU-accelerated computing with TensorFlow to detect objects, followed by how to train and develop a recurrent neural network (RNN) model to generate book scripts. By the end of this book, you’ll have gained the required expertise to build full-fledged machine learning projects at work.

Speech-to-text frameworks and toolkits


Many cloud-based AI providers offer speech to text as a service:

  • Amazon's offering for speech recognition is known as Amazon Transcribe. Amazon Transcribe allows transcription of the audio files stored in Amazon S3 in four different formats: .flac, .wav, .mp4, and .mp3. It allows an audio file with a maximum of two hours in length and 1 GB in size. The results of the transcription are created as a JSON file in an Amazon S3 bucket.
  • Google offers speech to text as part of its Google Cloud ML Services. Google Cloud Speech to Text supports FLAC, Linear16, MULAW, AMR, AMR_WB, and OGG_OPUS file formats. 
  • Microsoft offers a speech to text API as part of its Azure Cognitive Services platform, known as Speech Service SDK. The Speech Service SDK integrates with rest of the Microsoft APIs to transcribe recorded audio. It only allows the WAV or PCM file format with a single channel and sample rate of 6 kHz.
  • IBM offers a speech to text API as part if its Watson platform...
