Feed: Cloudera Engineering Blog » Cloudera Manager. Author: Justin Kestelyn. The new cluster templates feature in Cloudera Manager 5.7 makes creating clusters faster and easier. Often, after an Apache Hadoop cluster has been configured correctly, its admin will want to replicate the configuration in one or more clusters—whether for promoting a dev or staging cluster to production, or setting up a new production cluster with the same configuration as an existing one. For Cloudera customers, until recently the process for replicating cluster configurations was manual and error-prone. Starting in Cloudera Manager 5.7, the cluster templates feature make this process faster, ... Read More

Feed: Redis Labs. Author: Jay Johnson. Utilizing a machine learning API to create a scalable model artifact pipeline Managing large, pre-trained predictive models across an organization and ensuring the same version is in production can be a challenge with the rapid pace of changes in the AI/machine learning space. Here, we have an approach that demonstrates how to automate building, storing, and deploying predictive models from a Remote Machine Learning Data Store hosted on Redis Labs. This approach is focused on showing how DevOps CI/CD artifact pipelines can be used to build and manage machine learning model artifacts with Jupyter ... Read More

Feed: AWS Big Data Blog. Air travel can be stressful due to the many factors that are simply out of airline passengers’ control. As passengers, we want to minimize this stress as much as we can. We can do this by using past data to make predictions about how likely a flight will be delayed based on the time of day or the airline carrier.In this post, we generate a predictive model for flight delays that can be used to help us pick the flight least likely to add to our travel stress. To accomplish this, we will use Apache ... Read More

Feed: IBM Big Data & Analytics Hub - All Content . Author: james-kobielus. A data-driven culture is essential to business success in today’s world. To encourage data-driven innovations, organizations must make deepening investments in data science, data engineering, cognitive computing, and other core competencies. Just as important, organizations should be fostering collaborative cultures within which the professionals who engineer and model the data are in constant touch with those who understand the applications and own the business outcomes being sought. If everybody in the organization collaborates in the development of data-driven applications, the competitive advantages can be considerable. Going forward, ... Read More

Feed: All - O'Reilly Media. Author: Lukas Biewald. Eye of Providence. (source: Bureau of Engraving and Printing on Wikimedia Commons). Object recognition is one of the most exciting areas in machine learning right now. Computers have been able to recognize objects like faces or cats reliably for quite a while, but recognizing arbitrary objects within a larger image has been the Holy Grail of artificial intelligence. Maybe the real surprise is that human brains recognize objects so well. We effortlessly convert photons bouncing off objects at slightly different frequencies into a spectacularly rich set of information about the world around ... Read More
