Deep learning is a subset of machine learning that is modeled on the basis of the human brain. It essentially teaches computers what comes naturally to humans (learning by examples). In this blog, we discuss how deep learning models using background knowledge were used to achieve sequence learning on traffic and natural language. We also introduce the deep learning tool, TensorLayer.

Time series forecasting is an important statistical tool for predicting future events, needs, trends, etc., and can be applied to a variety of data sources. Jeremy Meier and David Noh, recent graduates of Clemson University’s Computer Science program, spoke at HPCC Systems Tech Talk episode 23 about the basic principles and components of time series forecasting using modern machine learning methods. This blog gives insight into their semester-long project, which focused on time series analysis and forecasting using financial datasets.

Cervical cancer is a leading cause of cancer-related death among women, with about half a million new cases worldwide in 2018 (WHO, 2018). 90% of cervical cancer deaths occur in low resource settings. This mortality could be reduced through effective prevention, screening, and treatment programs.

This ECL Tip spotlights the top ten most common Enterprise Control Language (ECL) compiler/runtime errors, and how to correct them. Developers often encounter these specific errors while learning ECL. Most of these errors are easy to fix, but it is important to understand what the error message is saying and what needs to be corrected.

This ECL Tip spotlights the Enterprise Control Language (ECL) SET and the functions that incorporate SET. ECL SET is a useful tool in query design and processing. One of the most common applications for ECL SET is to simplify code by eliminating multiple “OR” conditions in a filter.

The Enterprise Control Language (ECL) LOOP function has always been a powerful, yet tough function to understand and use. For this reason, changes were made to the HPCC Systems ECL Language Reference manual. The documentation updates make it easier to understand and effectively use the ECL LOOP function.

Chris Gropp, a PhD student at Clemson University, spoke at HPCC Systems Tech Talk 10, focusing on how to plan effectively at the start of a machine learning research project to achieve a successful outcome. This blog shares his experience on how to ask the right questions with machine learning, by taking a step back and carefully examining the requirements.
