Finally, after almost two years, we have a new series and something interesting to write about! If you didn't watch Episode 1, do it before reading this post as it might contain spoilers!

Let's now start with a preview of the starting scene of Episode (more...)

Democratize Data Science with Oracle Analytics Cloud – Predictions and Final Considerations

Democratize Data Science with Oracle Analytics Cloud - Predictions and Final Considerations

Oracle Analytics Cloud as an enabler for Data Science: this is the third post of a series which started with Episode I where we discussed the path from a Data Analyst to a Data Scientist and how to start a Data Science journey with OAC. Episode II was focused on Feature Engineering, Data Analytics and Machine Learning, showing how those steps can be performed in OAC using a visual and easily understandable interface.

This last (more...)

Democratize Data Science with Oracle Analytics Cloud - Data Analysis and Machine Learning

Welcome back! In my previous Post, I described how the democratization of Data Science is a hot topic in the analytical industry. We then explored how Oracle Analytics Cloud can act as an enabler for the transformation from Business Analyst to Data Scientist and covered the first steps in a Data Science project: problem definition, data connection & cleaning. In today's post, we'll cover the second part of the path: from the data transformation (more...)

Democratize Data Science with Oracle Analytics Cloud

In the last few weeks, I had the chance to speak both at Analytics and Data Summit held in Oracle HQ in San Francisco and OUG Norway Spring Conference 2019 on a wavy cruise between Oslo and Kiel. The underlying topic of the presentations was just one: demonstrate how Oracle Analytics Cloud can be used to bridge the gap between Business Analysts and Data Science.

Imagine: you only need to connect to the data, and (more...)

Spark Streaming and Kafka – Configuring a Kafka Connector

In my previous blog post, I covered the development of a custom Kafka Source Connector, written in Scala. This blog post is about deploying that Connector. We are getting closer to analysing the stream data in Spark - as promised in the title.

If you are installing a Connector from Confluent Hub, instead of installing a custom one, please follow this guide instead.

Hello, world!

Having joined Rittman Mead more than 6 years ago, the time has come for my first blog post. Let me start by standing on the shoulders of blogging giants, revisiting Robin's old blog post Getting Started with Spark Streaming, Python, and Kafka.

The blog post was very popular, touching on the subjects of Big Data and Data Streaming. To put my own twist on it, I decided to:

The Importance of Feature Engineering and Selection

In machine learning your model is only ever as good as the data you train it on. As such a significant proportion of your effort should be focused on creating a dataset that is optimised to maximise the information density of your data. Feature engineering and selection are the methods used for achieving this goal.

In this context, the definition of a feature will be a column or attribute of the data.

Feature engineering is (more...)

Oracle OpenWorld Europe : London 2019

Some eleven thousand people descended on Oracle OpenWorld Europe in London last week for two days of business and technical sessions delivered by a mixture of members of Oracle’s product team and end users giving real-world case studies of adoption of Oracle’s Cloud offerings and product roadmaps.

Something that may not surprise anyone is that at OpenWorld, to speak of anything other than Cloud or Autonomous would be somewhat blasphemous.

It’s a shrewd move this (more...)
