Azure Machine Learning service now supports NVIDIA’s RAPIDS

Azure Machine Learning service is the first major cloud ML service to support NVIDIA’s RAPIDS, a suite of software libraries for accelerating traditional machine learning pipelines with NVIDIA GPUs.

Just as GPUs revolutionized deep learning through unprecedented training and inferencing performance, RAPIDS enables traditional machine learning practitioners to unlock game-changing performance with GPUs. With RAPIDS on Azure Machine Learning service, users can accelerate the entire machine learning pipeline, including data processing, training and inferencing, with GPUs from the NC_v3NC_v2, ND or ND_v2 families. Users can unlock performance gains of more than 20X (with 4 GPUs), slashing training times from hours to minutes and dramatically reducing time-to-insight.

The following figure compares training times on CPU and GPUs (Azure NC24s_v3) for a gradient boosted decision tree model using XGBoost. As shown below, performance gains increase with the number of GPUs. In the Jupyter notebook linked below, we’ll walk through how to reproduce these results step by step using RAPIDS on Azure Machine Learning service.

How to use RAPIDS on Azure Machine Learning service

Everything you need to use RAPIDS on Azure Machine Learning service can be found on GitHub.

The above repository consists of a master Jupyter Notebook that uses

ONNX Runtime integration with NVIDIA TensorRT in preview

Today we are excited to open source the preview of the NVIDIA TensorRT execution provider in ONNX Runtime. With this release, we are taking another step towards open and interoperable AI by enabling developers to easily leverage industry-leading GPU acceleration regardless of their choice of framework. Developers can now tap into the power of TensorRT through ONNX Runtime to accelerate inferencing of ONNX models, which can be exported or converted from PyTorch, TensorFlow, and many other popular frameworks.

Microsoft and NVIDIA worked closely to integrate the TensorRT execution provider with ONNX Runtime and have validated support for all the ONNX Models in the model zoo. With the TensorRT execution provider, ONNX Runtime delivers better inferencing performance on the same hardware compared to generic GPU acceleration. We have seen up to 2X improved performance using the TensorRT execution provider on internal workloads from Bing MultiMedia services.

How it works

ONNX Runtime together with its TensorRT execution provider accelerates the inferencing of deep learning models by parsing the graph and allocating specific nodes for execution by the TensorRT stack in supported hardware. The TensorRT execution provider interfaces with the TensorRT libraries that are preinstalled in the platform to process the ONNX sub-graph

Intel and Microsoft bring optimizations to deep learning on Azure

This post is co-authored with Ravi Panchumarthy and Mattson Thieme from Intel.

We are happy to announce that Microsoft and Intel are partnering to bring optimized deep learning frameworks to Azure. These optimizations are available in a new offering on the Azure marketplace called the Intel Optimized Data Science VM for Linux (Ubuntu).

Over the last few years, deep learning has become the state of the art for several machine learning and cognitive applications. Deep learning is a machine learning technique that leverages neural networks with multiple layers of non-linear transformations, so that the system can learn from data and build accurate models for a wide range of machine learning problems. Computer vision, language understanding, and speech recognition are all examples of deep learning at play today. Innovations in deep neural networks in these domains have enabled these algorithms to reach human level performance in vision, speech recognition and machine translation. Advances in this field continually excite data scientists, organizations and media outlets alike. To many organizations and data scientists, doing deep learning well at scale poses challenges due to technical limitations.

Often, default builds of popular deep learning frameworks like TensorFlow are not fully optimized for training and

PyTorch on Azure: Deep learning in the oil and gas industry

This blog post was co-authored by Jürgen Weichenberger, Chief Data Scientist, Accenture and Mathew Salvaris, Senior Data Scientist, Microsoft

Drilling for oil and gas is one of the most dangerous jobs on Earth. Workers are exposed to the risk of events ranging from small equipment malfunctions to entire off shore rigs catching on fire. Fortunately, the application of deep learning in predictive asset maintenance can help prevent natural and human made catastrophes.

We have more information than ever on our equipment thanks to sensors and IoT devices, but we are still working on ways to process the data so it is valuable for preventing these catastrophic events. That’s where deep learning comes in. Data from multiple sources can be used to train a predictive model that helps oil and gas companies predict imminent disasters, enabling them to follow a proactive approach.

Using the PyTorch deep learning framework on Microsoft Azure, Accenture helped a major oil and gas company implement such a predictive asset maintenance solution. This solution will go a long way in protecting their staff and the environment.

What is predictive asset maintenance?

Predictive asset maintenance is a core element of the digital transformation of chemical plants. It

Build your own deep learning models on Azure Data Science Virtual Machines

As a modern developer, you may be eager to build your own deep learning models but aren’t quite sure where to start. If this is you, I recommend you take a look at the deep learning course from fast.ai. This new fast.ai course helps software developers start building their own state-of-the-art deep learning models. Developers who complete this fast.ai course will become proficient in deep learning techniques in multiple domains including computer vision, natural language processing, recommender algorithms, and tabular data.

You’ll also want to learn about Microsoft’s Azure Data Science Virtual Machine (DSVM). Azure DSVM empowers developers like you with the tools you need to be productive with this fast.ai course today on Azure, with virtually no setup required. Using fast cloud-based GPU virtual machines (VMs), at the most competitive rates, Azure DSVM saves you time that would otherwise be spent in installation, configuration, and waiting for deep learning models to train.

Here is how you can effectively run the fast.ai course examples on Azure.

Microsoft joins the SciKit-learn Consortium

As part of our ongoing commitment to open and interoperable artificial intelligence, Microsoft has joined the SciKit-learn consortium as a platinum member and released tools to enable increased usage of SciKit-learn pipelines.

Initially launched in 2007 by members of the Python scientific community, SciKit-learn has attracted a large community of active developers who have turned it into a first class, open source library used by many companies and individuals around the world for scenarios ranging from fraud detection to process optimization. Following SciKit-learn’s remarkable success, the SciKit-learn consortium was launched in September 2018 by Inria, the French national institute for research in computer science, to foster growth and sustainability of the library, employing central contributors to maintain high standards and develop new features. We are extremely supportive of what the SciKit-learn community has accomplished so far and want to see it continue to thrive and expand. By joining the newly formed SciKit-learn consortium, we will support central contributors to ensure that SciKit-learn remains a high-quality project while also tackling new features in conjunction with the fabulous community of users and developers.

In addition to supporting SciKit-learn development, we are committed to helping Scikit-learn users in training and production scenarios through

Analyze data in Azure Data Explorer using KQL magic for Jupyter Notebook

Exploring data is like solving a puzzle. You create queries and receive instant satisfaction when you discover insights, just like adding pieces to complete a puzzle. Imagine you have to repeat the same analysis multiple times, use libraries from an open-source community, share your steps and output with others, and save your work as an artifact. Notebooks helps you create one place to write your queries, add documentation, and save your work as output in a reusable format.

Jupyter Notebook allows you to create and share documents that contain live code, equations, visualizations, and explanatory text. Its includes data cleaning and transformation, numerical simulation, statistical modeling, and machine learning.
