#012 TF Transfer Learning in TensorFlow

2020-02-17 datahacker.rs 160

Highlights: In this post we are going to show how to build a computer vision model without building it from scratch. The idea behind transfer learning is that a neural network that has been trained on a large dataset can apply its knowledge to a dataset it has never seen before. That is why it’s called transfer learning; we transfer the learning of an existing model to a new dataset. Tutorial Overview: Introduction Transfer learning with… Read more

#001 TF 2.0 An Introduction to TensorFlow 2.0

2020-02-01 datahacker.rs 113

What is TensorFlow 2.0? TensorFlow is an open source library for numerical computations built by Google Brain team. TensorFlow is based on the data flow graphs. Moreover, it actually allows developers to create data flow graphs—structures that describe how data moves through a graph, or a series of processing nodes. Each node in the graph represents a mathematical operation, and each connection or edge between nodes is a multidimensional data array or a tensor. If… Read more

#003 TF 2.0 Eager Execution- A Pythonic way of using TensorFlow

2020-02-01 datahacker.rs 112 TensorFlow

TensorFlow uses Eager execution, which is a more convenient way to execute the code, and also more “Pythonic”. It is a default choice in the latest version TensorFlow 2.0. In TensorFlow 1.x, we first need to write a Python program that constructs a graph for our computation, the program then invokes Session.run(), which hands the graph off for execution to the C++ runtime. This type of programming is called declarative programming (specification of the computation… Read more
