How hot will it be on Christmas Day?

16 December 2019

Weather forecasting is one of the oldest forms of predictive analytics. One data source we often look at here at The Red Fox Group is weather data. 

While we don’t have any trained meteorologists on staff (so please don’t ask for detailed forecasts!), we can look at how the weather may be impacting your business performance. Do your retail sales slump or outperform on rainy days? Do more people visit your website when they’re stuck inside on cold days?

But given Christmas is getting nearer, we thought we’d take a look at what to expect on Christmas Day.

In Australia the Bureau of Meteorology compiles and makes publicly available observation data from thousands of weather stations around the country (with 762 stations currently reporting temperature data). We’ve analysed historic data for the last hundred years for the state capitals, here is what we’ve found…

On an average Christmas Day the mainland state capitals tend to reach the mid-to-high twenties. Perth, Brisbane and to a lesser extent Adelaide tend to be warmer than Sydney and Melbourne. Hobart is noticeably cooler than any of them. If you’re on the mainland, then chances are it will be hotter than 25 degrees. But as the graph shows, there’s a lot of variation!

Melbourne has a higher record Christmas Day temperature than Sydney – but its coolest ever Christmas Day was also cooler than Sydney’s. As will surprise no one who’s been there, Melbourne’s temperature is simply more variable.

In the last century the hottest Christmas Day in any capital city was in Perth, which hit a scorching 42 degrees in 1968.

Unsurprisingly, the coolest maximum was in Hobart, which reached just 12.6 degrees in 1984.

On Christmas Day last year the hottest capital city was Adelaide, which hit 37.9 degrees.

We are not meteorologists. Don’t ask us what the temperature will be next Wednesday.

But we can use weather data to help understand and predict things. Such as the number of people attending sporting matches, visiting cultural institutions, or buying particular products.

Regardless of what the weather is like on Christmas Day, we here at The Red Fox Group wish you and your clients all the best for a great break.

The 5 biggest data news stories of 2019

10 December 2019

Moore’s Law states that computing power doubles every two years. This means that the field of data science is constantly evolving as computers become more powerful. 

As 2019 draws to a close we thought we’d take a look at some of the biggest headlines of the year concerning data. 


1. The rise of the Citizen Data Scientist

As more free or cheap data analytics tools hit the market, and governments become better at proactively releasing big data sets the last few years have seen the emergence of the concept of the Citizen Data Scientist – essentially someone who does data science as a hobby or in their spare time, often without any formal training. 

Gartner (who originally created the term Citizen Data Scientist back in 2016) is predicting that next year we will reach a tipping point – citizen data scientists will surpass data scientists in the amount of advanced analytics produced. 

This opens huge questions around accuracy and the value of trained skills.   


2. Google’s Quantum Computing breakthrough

This year saw a major advance in computer science that will quickly change the face of big data and analytics. 

They reportedly achieved quantum supremacy – where a functional quantum computer was able to perform a task faster than any existing classical computer. 

This proves that the theory behind a quantum computer is viable and will only spur on additional investment in this cutting-edge field.  

The increased computing power available will mean increased collection of data and more powerful artificial intelligence to analyse it.  

Quantum computing is on the way. And it will change the world. 


3. Consumer data privacy improvements

The fallout from the 2018 Cambridge Analytica scandal continues. Consumers are more aware than ever of risks to their own data privacy – here in Australia over 2.5 million citizens opted out of the Federal Government’s My Health Record digital health system by the time of the close off period in February of this year.  

Big firms like Google and Apple are beefing up their consumer data protections and making sure their customers know how seriously they are taking the issue.

4. GPT2

Back in February OpenAI announced that they had developed an artificial intelligence algorithm so powerful at natural language processing that it was able to write believable fake news. In a world where social media is filled with fake news, many people found this understandably unnerving.  

Over the course of the year they performed a staged release of the technology and by July had released the GPT2 algorithm in full. 

OpenAI claim they so far they have seen “no strong evidence of misuse” – but if it is so good, then there may be no way of seeing how it is already being used to spread misinformation. 

You can explore a demo of the algorithm here. 


5. The Apple Credit Card and algorithmic bias

Tech entrepreneur David Heinemeier Hansson made global news with a series of tweets claiming that his Goldman Sachs backed Apple Credit Card gave him a credit limit 20 times greater than his wife, despite the fact that the couples file tax returns jointly. 

This opened the door to questions around algorithmic bias.  

Goldman Sachs denied accusations of bias and offered to reevaluate credit limits on a case-by-case basis.  

This leads to some big questions. Could a credit limit algorithm be sexist? How much transparency should there be on algorithms and the decisions they make. 


Using AI & Machine Learning to make your work m...

04 December 2019

It’s easy to dismiss artificial intelligence and machine learning as just buzzwords, or technology that belongs in the distant future.

But that’s not the case. Here at The Red Fox Group we’re utilising advanced machine learning and artificial intelligence techniques to drive efficiencies for our customers, even in places where you might least expect it.

We’ve recently deployed a new version of the business card scanner in SwiftFox CRM which now utilises some very exciting cutting-edge features.

Optical Character Recognition is a technology that has been around for decades. Computers have long been able to read text and convert it to digitised information. We’ve taken that to a new level by partnering with Microsoft to utilise their Computer Vision cognitive service.

Computer Vision is OCR technology on steroids. It’s enhanced with machine learning models so SwiftFox can now make intelligent assumptions about the nature of objects and characters rather than just trying to map it using simple pattern recognition.

This gives it huge advantages. It can handle blurred text, extravagant fonts, and text at arbitrary angles – even upside down. It's much more accurate because of that. If you’re scanning a business card in real time at a cocktail function, or in the Uber on the way home, this will radically improve the accuracy of text recognition.

But that’s just the start.

Once we have captured the text out of an image of a business card we’re able to use machine learning text analysis to figure out how the data is structured and how it relates to our data models for people and organisations.

We get both Microsoft and Google’s cloud AI services (Microsoft Text Analytics and Google Cloud Natural Language) to analyse the grouped text structures and pass back which data fields each piece of text should map to, and how confident the artificial intelligence is of its finding.

SwiftFox then analyses the results of the two-machine learning models and uses the data that is most accurate to pre-populate data fields.

A very common problem with traditional business card scanning technology is that it has made a lot of assumptions about the text layout – eg most business cards have the person’s title directly after their name. But what if the business name comes after the person’s name? Or their job title comes first? We’re using machine learning to bypass assumptions and are getting far more accurate data back on what information is captured in each piece of text.

This means that when you’re loading a new contact through the business scanner, the chances are really good that we’ve correctly identified which parts of the business card go into the right part of the database. No more accidentally creating new organisations called ‘Managing Director’!

Hopefully this gives you a better idea of how we’re using advanced artificial intelligence and machine learning to make even simple tasks more efficient.
