As of HPCC Systems version 7.6.0, a new cryptographic module has been added to the ECL Standard Library. Within this module, there is an assortment of cryptographic features available to ECL developers to utilize in order to safeguard their sensitive data, using industry standard cryptographic algorithms. Features include digital hash algorithms, symmetric and asymmetric encryption and decryption, and digital signatures, all of which can be applied to individual columns within an ECL dataset.

This ECL Tip spotlights the Enterprise Control Language (ECL) DISTRIBUTE function. The ECL DISTRIBUTE function redistributes data across all nodes in a cluster. Using the DISTRIBUTE function can help prevent “cluster skew”, by distributing data evenly across all nodes. This function can be used on Thor or the ROXIE cluster.

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.

As of 7.2.0, HPCC Systems platform users have access to a new Web service called WsStore. The service is a general purpose key-value (KV) store. A key-value store is a type of non-relational database that uses a simple key-value pair mechanism to store data in which the key serves as a unique identifier to index associated value entries. Keys and values can be anything--ranging from simple literals to complex compound objects.

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.

This ECL Tip spotlights the Enterprise Control Language (ECL) TABLE function. The TABLE function is a versatile tool for ETL (extract, transform, load) operations, and was one of the first ECL statements available, well before the family of TRANSFORM functions.
