TensorFlow is an open-source software library developed by Google for machine learning and artificial intelligence. It was first released in 2015. TensorFlow is primarily designed for deep learning, and usually referred to as a library for deep learning, but it can also be used for traditional machine learning tasks.

It supports a variety of programming languages, including Python, C++, and Java, and can be used for a range of machine learning tasks, including image and speech recognition, natural language processing, and predictive analytics.


[ChatGPT] TensorFlow is an end-to-end platform for developing and deploying machine learning/deep learning models. End-to-end means that TensorFlow provides a comprehensive solution for the entire process of building and using machine learning models, from data preparation to model training and deployment:

  • Data Preparation: TensorFlow provides tools and libraries for preprocessing and cleaning data, preparing it for use in machine learning models.
  • Model Building: TensorFlow provides a wide range of tools and libraries for building different types of machine learning models, including deep learning models, reinforcement learning models, and more.
  • Model Training: TensorFlow provides a powerful distributed training framework that enables users to train models on large datasets using multiple GPUs or TPUs.
  • Model Deployment: TensorFlow provides tools and libraries for deploying machine learning models to a wide range of platforms, including mobile devices, web servers, and more.
  • Monitoring and Maintenance: TensorFlow provides tools for monitoring and maintaining deployed models, including tools for debugging, profiling, and performance tuning.


Some important features of TensorFlow are:

  • Allow writing fast deep learning codes (able to run on a GPU/TPU)
  • GPUs (Graphics Processing Unit) are very fast at doing numerical calculations
  • TPU (Tesor Processing Unit) is an AI accelerator application-specific integrated circuit (ASIC) developed by Google specifically for neural network machine learning, particularly using Google's own TensorFlow software.
  • Able to access many pre-built deep learning models (TensorFlow Hub)

TensorFlow certification:

Before you take the exam, please review our Candidate Handbook: https://www.tensorflow.org/static/extras/cert/TF_Certificate_Candidate_Handbook.pdf


Google provides a certification program for TensorFlow called the "TensorFlow Developer Certificate". This certification program is designed to test and validate your knowledge and skills in developing and deploying TensorFlow models for real-world applications.

The TensorFlow Developer Certificate exam is a computer-based exam that includes a combination of multiple-choice and coding questions.

To take the exam and earn the certification, you must pay a fee. As of my knowledge cut-off in September 2021, the fee for the exam was $100 USD.

In TensorFlow, a Tensor is the fundamental data structure. It is a multi-dimensional array that represents input data, intermediate results, and output data. They are used to represent (store and manipulate) data of various types, including images, text, and numerical values.

Tensors can be thought of as a data structure that generalize scalars, vectors, matrices, and higher-dimensional arrays to an arbitrary number of dimensions.
