CV models can be built with multiple deep learning frameworks like TensorFlow, PyTorch, and Apache MXNet. These models typically have a large input payload of images or videos of varying size. Advanced deep learning models for use cases like object detection return large response payloads ranging from tens of MBs to hundreds of MBs in size. Large request and response payloads can increase model serving latency and subsequently negatively impact application performance. You can further optimize model serving stacks for each of these frameworks for low latency and high throughput.

We can add customized Python code to process input and output data via input_handler and output_handler methods. The customized Python code must be named inference.py and specified through the entry_point parameter. We add preprocessing to accept an image byte stream as input and read and transform the byte stream with tensorflow.keras.preprocessing:
In this post, we demonstrated how to reduce model serving latency for TensorFlow computer vision models on SageMaker via in-server gRPC communication. We walked through a step-by-step process of in-server communication with TensorFlow Serving via REST and gRPC and compared the performance using two different models and payload sizes. For more information, see Maximize TensorFlow performance on Amazon SageMaker endpoints for real-time inference to understand the throughput and latency gains you can achieve from tuning endpoint configuration parameters such as the number of threads and workers.
SageMaker provides a powerful and configurable platform for hosting real-time computer vision inference in the cloud with low latency. In addition to using gRPC, we suggest other techniques to further reduce latency and improve throughput, such as model compilation, model server tuning, and hardware and software acceleration technologies. Amazon SageMaker Neo lets you compile and optimize ML models for various ML frameworks to a wide variety of target hardware. Select the most appropriate SageMaker compute instance for your specific use case, including g4dn featuring NVIDIA T4 GPUs, a CPU instance type coupled with Amazon Elastic Inference, or inf1 featuring AWS Inferentia.
If you want to succeed in a career as either a data scientist or an AI engineer, then you need to master the different deep learning frameworks currently available. Simplilearn offers the Deep Learning (with Keras & TensorFlow) Certification Training course that can help you gain the skills you need to start a new career or upskill your current situation.
The deep learning course familiarizes you with the language and basic ideas of artificial neural networks, PyTorch, autoencoders, etc. When you finish, you will know how to build deep learning models, interpret results, and even build your deep learning project.
In 2007, right after finishing my Ph.D., I co-founded TAAZ Inc. with my advisor Dr. David Kriegman and Kevin Barnes. The scalability, and robustness of our computer vision and machine learning algorithms have been put to rigorous test by more than 100M users who have tried our products.
Machine learning libraries exist for many applications - AI-powered tools, predicting, computer vision, and classifying, to name a few. If you're looking to use these libraries to create applications or solve problems, you'll want to choose the right tool for the job. Let's take a look at the differences between some of the more frequently mentioned libraries to help you decide.
Consider TensorFlow if you want to use a deep learning approach in conjunction with hardware acceleration through GPUs and TPUs, or on a cluster of computers (which scikit-learn doesn't natively support).
PyTorch is a deep learning software library for Python, C++ and Julia. PyTorch is primarily used for end-to-end building and training of deep neural networks with the ability to create custom models and learning algorithms.
TensorFlow is a low-level deep learning library that provides workflows to high-level APIs such as Keras - albeit with less computational power. TensorFlow is currently more widely used than PyTorch.
Keras is a deep learning-centric library built on top of TensorFlow. Keras supports Python and R, while Tensorflow supports the major languages (Python, C++, Java, and Javascript, unofficially Go, and Swift being archived).
Consider Keras if you're relatively new to deep learning or looking to use a high level API that makes the most of the TensorFlow framework. As with any library, Keras takes into account best practices with comparatively less complexity.
Semantic segmentation, object detection, and image recognition. Computer vision applications integrated with deep learning provide advanced algorithms with deep learning accuracy. MATLAB provides an environment to design, create, and integrate deep learning models with computer vision applications.
This kind of programming will probably strike most R users as being exotic and obscure, but my guess is that because of the long history of dataflow programming and parallel computing, it was an obvious choice for the Google computer scientists who were tasked to develop a platform flexible enough to implement arbitrary algorithms, work with extremely large data sets, and be easily implementable on any kind of distributed hardware including GPUs, CPUs, and mobile devices.
The keras R package wraps the Keras Python Library that was expressly built for developing Deep Learning Models. It supports convolutional networks (for computer vision), recurrent networks (for sequence processing), and any combination of both, as well as arbitrary network architectures: multi-input or multi-output models, layer sharing, model sharing, etc. (It should be pretty clear that the Python code that makes this all happen counts as good stuff too.)

The applications of deep learning models and computer vision in the modern era are growing by leaps and bounds. Computer vision is one such field of artificial intelligence where we train our models to interpret real-life visual images. With the help of deep learning architectures like U-Net and CANet, we can achieve high-quality results on computer vision datasets to perform complex tasks. While computer vision is a humungous field with so much to offer and so many different, unique types of problems to solve, our focus for the next couple of articles will be on two architectures, namely U-Net and CANet, that are designed to solve the task of image segmentation.
Some of the most crucial applications of image segmentation include machine vision, object detection, medical image segmentation, machine vision, face recognition, and so much more. Before you dive into this article, I would suggest checking out some optional pre-requisites to follow along with this article. I would recommend checking the TensorFlow and Keras guides to get familiar with these deep learning frameworks as we will utilize them to construct the U-Net architecture. Below is the list of the table of contents for understanding the list of concepts that we will cover in this article. It is recommended to follow through the entire article, but you can feel free to check out the specific sections if you know some concepts already.
In this section of the article, we will look at the TensorFlow implementation of the U-Net architecture. While I am utilizing TensorFlow for computation of the model, you can choose any deep learning framework such as PyTorch for a similar implementation. We will look at the working of the U-Net architecture along with some other model structures with PyTorch in future articles. However, for this article, we will stick to the TensorFlow library. We will be importing all the required libraries and constructing our U-Net architecture from scratch. But, we will make some necessary changes that will improve the overall performance of the model as well as make it slightly less complex.
The U-Net architecture is one of the most significant and revolutionary landmarks in the field of deep learning. While the initial research paper that introduced the U-Net architecture was to solve the task of Biomedical Image Segmentation, it was not limited to this single application. The model could and can still solve the most complex problems in deep learning. Although some of the elements in the original architecture are outdated, there are several variations of this architecture. These include LadderNet, U-Net with attention, the recurrent and residual convolutional U-Net (R2-UNet), and other similar networks which are derived successfully from the original U-Net Models. 2ff7e9595c
