Feed: Featured Blog Posts - Data Science Central. Author: Jonathan Symonds. TLDR: Neural Networks are powerful but complex and opaque tools. Using Topological Data Analysis, we can describe the functioning and learning of a convolutional neural network in a compact and understandable way. The implications of the finding are profound and can accelerate the development of a wide range of applications from self-driving everything to GDPR.Introduction Neural networks have demonstrated a great deal of success in the study of various kinds of data, including images, text, time series, and many others.  One issue that restricts their applicability, however, is the ...

Feed: Featured Blog Posts - Data Science Central. Author: lakshmi yarlagadda. Over the past decade, we have seen a shift towards virtualization, a stepping stone to complete cloud utilization. However, even by leveraging virtualization, you still need the appropriate building blocks for a private cloud environment. This involves going beyond simply virtualizingcompute and other central data center subsystems (i.e., network and storage), and requires you to enable flexible APIs in order to automate resource provisioning and orchestration. 1 Open source Some say that OpenStackis the largest open source project ever. It combines computing, networking, and storage subsystems in layers via APIs within ... Read More

Feed: Featured Blog Posts - Data Science Central. Author: Amit Supe. Digital world is all around us! Disruptive Business Models is the new phenomenon! It means different things (not just internet of things) to different people and businesses. Some industries are traditionally slow in adapting new technologies. For example, AOVC (Asset Oriented Value Chains – Natural Resources, Metals and Chemicals) have not explored digital to it’s full potential. Analytics is one of the key components of this revolution. It it not just about capturing data of business operations but to leverage actionable insights for making intelligent products, enhancing customer experience ... Read More

Feed: R-bloggers. Author: rOpenSci - open tools for open science. Part of rOpenSci’s mission is to create technical infrastructure in the form of carefully vetted R software tools that lower barriers to working with data sources on the web. Our open peer software review system for community-contributed tools is a key component of this. As the rOpenSci community grows and more package authors submit their work for peer review, we need to expand our editorial board to maintain a speedy process. As our recent post shows, package submissions have grown every year since we started this experiment, and we see ... Read More

Feed: IBM Big Data & Analytics Hub - All Content; Author: matthew-johnsen; Running a machine learning pilot project is a great early step on the road to full adoption.To get started, you’ll need to build a cross-functional team of business analysts, engineers, data scientists and key stakeholders. From there, the process looks a lot like the scientific method taught in school. Here’s how it works: Identify an opportunity. Start with a problem tied directly to a specific business outcome. Make sure the subject of your pilot is small enough to tackle and clear enough to measure. For example, if you’re ... Read More

Feed: Cognitive Class Author: James Reeve Every data scientist I know spends a lot of time handling data that originates in CSV files. You can quickly end up with a mess of CSV files located in your Documents, Downloads, Desktop, and other random folders on your hard drive. I greatly simplified my workflow the moment I started organizing all my CSV files in my Cloud account. Now I always know where my files are and I can read them directly from the Cloud using JupyterLab (the new Jupyter UI) or my Python scripts. This article will teach you how to ... Read More

In business, we typically analyze that data with charts, graphs, or lists to create actionable insights. However, there is one element missing with traditional data analysis, and that is the “where” element. This is when geoanalytics becomes relevant. Geoanalytics is the correlation between data and its physical location. This means that more insights on the data can be created, such as dynamic pricing and operational efficiency. How handytec Delivers Geoanalytics handytec is an Ecuadorian company specializing in providing customized big ... Read More

Feed: R-bloggers. Author: filip Schouwenaars. Immediate and personalized feedback has been central to the learning experience on DataCamp since we launched the first courses. If students submit code that contains a mistake, they are told where they made a mistake, and how they can fix this. You can play around with it in our free Introduction to R course. The screenshot below is from our Intermediate R course. To check submissions and generate feedback, every exercise on DataCamp features a so-called Submission Correctness Test, or SCT. The SCT is a script of custom tests that assesses the code students submitted ... Read More
