Are Data Scientists Evolving With the Rise of Artificial Intelligence?

As developments in machine learning (ML) are expected to progress at a phenomenal pace, it is set to become one of the most powerful tools for businesses to enhance productivity and drive innovation. While ML, one of the most popular artificial intelligence (AI) applications, holds a lot of promise for businesses, is the role of data scientist today already evolving in order to keep up with the change?


What Is Next in AI

Continued advances in AI will see autonomous systems perceive, learn, decide, and act on their own, but to ensure the effectiveness of these systems, the machine will need to be able to explain their decisions and actions to humans. This is so called explainable AI.

“In the future, many AI systems are going to interact with people, especially those who will take responsibilities, hence the reason why AI needs to be explainable, meaning that the behavior of the system needs to be easily expected and interpreted by people,” said Min Sun, Chief AI Scientist at Appier.

Sun also pointed out that in the future, AI is going to be less supervised, which means that it will require less human inputs, and be more creative.

Data science was previously concerned with time-consuming ML tasks, such as data wrangling and feature engineering, which could take up 80 percent of data scientist’s time, but such tasks can be automated sooner or later, according to Deloitte’s Technology, Media and Telecommunications Predictions 2018 report.

Such advances in AI will give data scientists more time to execute more complex tasks. However, it brings up a problem: a majority of data scientists doesn’t possess the required advanced machine learning skills, such as deep learning (DL), a subfield of ML.


The Impact of Machine Learning on Businesses

Previously, companies might have spent a lot of time doing guesswork based on consumer data gathered online and offline, which is usually fragmented and siloed. With an AI-based approach, brands are able to unify data across different channels for a holistic view and analysis of the audience and their conversion journey.

Machine learning and deep learning allow a computer to take in huge sets of data and not only predict the outcome, but also understand what the desired output should be. It can be integrated into many aspects of digital marketing, such as predicting consumer behavior and campaign outcomes, marketing automation, sophisticated buyer segmentation and sales forecasting.

With these technologies, businesses have a more efficient and cost-effective way to build trustworthy AI systems to be used by professionals and/or to be naturally interacted with human users, according to Hsuan-Tien Lin, Appier’s Chief Data Scientist.

So, it’s no surprise to see that businesses are increasingly catching up on the adoption of AI technology. According to the International Data Corporation (IDC), AI continues to be a key spending area for companies in the near future, with worldwide spending on cognitive and AI systems increasing 54.2 percent in 2018 to US$19.1 billion. That number could go up to US$52.2 billion in 2021, IDC predicted.


Bridging the Machine Learning Skills Gap

As more businesses look to adopt AI techniques like machine learning and deep learning, data scientists are urged to upskill, in order to keep up with the current trends. Rudina Seseri, Founder and Managing Partner at Glasswing Ventures, wrote in Forbes, “Data scientists – at least the successful ones – will evolve from their current roles to becoming machine learning experts or some other new category of expertise, yet to be given a name”.

Leading tech companies such as Google and Microsoft have already been offering relevant courses aiming to help bridge the talent gap. For example, Google not only made its ‘Machine Learning Crash Course’ available to the general public earlier this year as part of the company’s ‘Learn With Google AI’ initiative, it has also launched a machine learning specialization on Coursera, an online learning platform.

Andrew Ng, one of the world’s best-known AI experts, also launched a set of courses on deep learning through Coursera in 2017, hoping to help more people get up to speed on key developments in AI.

While technical skills will be foundation of the role of data scientists, it’s crucial for them to master human-centric skills too. Data scientists will need to develop a better understanding of the overarching business strategy and business challenges in real-world scenarios, in order to create solutions that can solve real problems.

Businesses are looking for a total solution, Sun pointed out. For instance, self-driving car manufacturers need a system consisting of perception, communication, decision-making and control. In the old days, each module was designed separately, but this has been transitioning to more jointly design since the fatal self-driving Uber crash, where the perception system identified the pedestrian, but the decision-making module failed to react.

The ability for scientists to design a complete system consisting of multiple ML modules will become more and more important,” he said. “In the future, data scientists will need to have the modeling and analysis skills at the system-level to provide business people with the right total solution to the market.”

3 Ways to Stay Relevant With Real-Time Marketing Automation

It is a question facing every marketer – in today’s fast-moving world, how do you stay relevant? One of the most effective ways is to make sure you are acting on the latest data possible, in order to serve them up-to-date offers that meet their current needs. It is no good sending a coupon for a set of kitchen knives if your customer only showed a fleeting interest in them last week. With the help of real-time marketing automation, you can engage with your customers not only in a timely fashion, but also at scale.   The Importance of Engaging Audiences in Real Time As with all data-driven marketing, the quality of your output depends on the quality of your data. If the data is inaccurate, it cannot help you market effectively. It needs to be representative of your customers’ current thoughts, actions and behaviors, in order to help you create marketing content that they find more relevant. Also, customers’ online behaviors and interests change rapidly, and there is no shortage of alternatives for them to choose from the internet, providing plenty of distraction. If they express an interest in a product or service, there is no guarantee that it

Is AI the Remedy for Brand Safety Woes?

When it comes to programmatic advertising today, companies are focusing on brand safety as much as they are on impressions, click-throughs and revenue generation, but it is virtually impossible to monitor brand safety due to the scale and speed that programmatic offers. However, with the increasing adoption of artificial intelligence (AI) in digital marketing, such technology will not only help marketers better target their ideal audience, it might just be the cure for protecting advertiser dollars.   Programmatic Could Compromise Your Brand Safety Brand safety came under the spotlight following a number of advertising mishaps in early 2017. Alexi Mostrous from The Times revealed that many household brands were unwittingly supporting terrorism on YouTube by placing their ads on hate and Islamic state videos. Later the same year, ads from some of the world’s biggest brands were seen to be running alongside videos that sexually exploited children. This led to widespread panic, with many brands pulling programmatic spend until they could be assured by publishers like Google that measures were being taken to filter out such content. In 2018, brand safety has broadened to cover any offensive, illegal or inappropriate content that appears next to a brand’s assets, thus threatening

Your 8-Point Martech Checklist to Nail Customer Engagement

The current landscape of marketing technology (martech) is rapidly shifting, with an explosion in new ways to reach customers and deliver exceptional customer engagement.
