Below is the running application: Purpose and Motivation Google … Read more
In previous articles, we have introduced two types of image segmentation loss functions. Today, we will share commonly used multi-class image segmentation loss functions such as multi-class cross-entropy, weighted multi-class cross-entropy, multi-class Dice coefficient, multi-class Focal Loss, etc., and provide code to reproduce the above loss functions in TensorFlow. 1. Cross Entropy The cross-entropy loss … Read more
The global deep learning systems market is expected to reach $93.34 billion by 2028, with a compound annual growth rate of 39.1%. Deep learning, also known as deep neural learning, is a subset of machine learning and an application of artificial intelligence, where machines mimic the working of the human brain and use artificial neural … Read more
Installing TensorFlow on Windows Installing Python First, you need to install Python on your Windows system. It is recommended to use the official Python distribution, which is Anaconda, as it comes with many scientific computing libraries, such as numpy and scipy, which are also used in TensorFlow. You can download and install Anaconda from the … Read more
Commonly used image segmentation loss functions include binary cross-entropy, dice coefficient, Tversky, and Focal Loss. Today, I will reproduce the above loss functions in TensorFlow and compare the results. 1. Cross Entropy The cross-entropy loss function compares the predicted class values with the target values on a pixel-by-pixel basis, and then averages the values over … Read more
In the previous article, I introduced how to perform data parallelism with multiple GPUs in TensorFlow. In this article, I will discuss how to debug TensorFlow models. Compared to regular Python code, debugging TensorFlow code can be relatively difficult due to the symbolic nature of TensorFlow. Here, I will introduce some debugging tools included in … Read more
Deep Learning Frameworks Author: Horace He Revise: louwill source: https://thegradient.pub/state-of-ml-frameworks-2019-pytorch-dominates-research-tensorflow-dominates-industry/ For many practitioners in the deep learning industry, mastering one or more deep learning frameworks is one of the essential skills for daily work. After a period of chaos in the deep learning framework market, a dominant market structure has gradually formed with TensorFlow and … Read more
