Machine learning has the potential to transform the way organisations interact with the world, to move faster and to provide better customer experience. But while machine learning’s long-term potential certainly looks bright, its adoption in the enterprise may advance more slowly than originally thought. So what’s the holdup? John Rakowski, Market Specialist for Application Performance Management and Analytics, at AppDynamics discusses the challenges for enterprises when adopting machine learning technology.

What are the main challenges standing in the way of widespread adoption of machine learning in the enterprise?

Part of the challenge is a lack of understanding around what machine learning is. Machine learning is an application or subset of AI, which is generally thought of as higher-order decision-making intelligence. Machine learning is really about applying mathematics to different domains. It locates meaning within extremely large volumes of data by cancelling out the noise. It uses algorithms to parse the data and draw conclusions from it, such as what constitutes normal behaviour.

Do you think that the lack of understanding stems from uncertainty about what machine learning can do?

It’s important to understand that machine learning algorithms don’t enter chess tournaments. What they are really good at is adapting to changing systems without human intervention while continuing to differentiate between expected and anomalous behaviour. This makes machine learning useful in all kinds of applications – think everything from security to healthcare -as well as classification and recommendation engines, and voice and image identification systems.

Consumers interact daily with dozens of machine learning systems including Google Search, Google ads, Facebook ads, Siri and Alexa, as well as virtually any online product recommendation engine from Amazon to Netflix. The challenge for enterprises is understanding how machine learning can add value to their business.

So, how can machine learning be introduced to an enterprise?

Machine learning is usually introduced into an enterprise in one of two ways. The first is that one or two employees start applying machine learning to gain insight into data they already have access to. This requires a certain amount of expertise in data science and more importantly, domain knowledge. An understanding of the business value and the customer need for digital services (applications) that are utilised is fundamental— but these skills are often in short supply.

The second is by purchasing a solution, such as security software or application performance monitoring solution, that uses machine learning. This is by far the easiest way to begin to realise the benefits of machine learning.

For example at AppDynamics, we apply machine learning to understand what constitutes a ‘healthy’ application from a performance and user experience perspective. We utilise dynamic baselining to work out how each step in a user journey for an application should perform. For example, in an e-commerce application, this could include steps such as login, or search for a product. These algorithms also take into account business variables such as important times of the year like Black Friday, and then alerts are generated when performance deviates. This saves organisations time in terms of manually working out acceptable performance thresholds and also ensures that our solution provides fast ROI in any complex, enterprise environment.

Is there a challenge with data preparations for enterprises introducing machine learning?

Machine learning can sound deceptively simple. It’s easy to assume that all you have to do is collect the data and run it through some algorithms. The reality is very different. Once you have collected the data, you then have to aggregate it. You need to determine if there are any problems with it. Your algorithm needs to be able to adapt to missing data, outlying data, garbage data, and data that’s out of sequence.

Is there a big issue for machine learning from the lack of public labelled datasets?

There is, yes, because for an algorithm to make sense of a collection of data points, it needs to understand what those points represent. In other words, it needs to be able to apply pre-established labels to the data.

The availability of publicly labelled datasets would make it much easier for companies to get started with machine learning. Unfortunately, these do not yet exist, and without them, most companies are looking at a ‘cold start’.

There’s a need for domain knowledge too, is this another challenge?

At its best, machine learning represents the perfect marriage between an algorithm and a problem. For example, at AppDynamics, we apply dynamic baselining algorithms to ensure that our customers get alerted early on emerging application performance problems. This means domain knowledge – knowing what is a problem – is a prerequisite for effective use of the technology. Unfortunately, in a number of enterprise IT use cases, knowledge is built up in siloes within organisations, resulting in disparate pockets of knowledge a lack of business context.

Are there cultural changes needed for an organisation to successfully adopt machine learning?

Companies need to accept that they need to move faster as a digital business, and machine learning and automation is a prerequisite for success. Data is at the heart of machine learning, and those companies that culturally react to the importance of real-time insight that can be trusted and acted upon quickly, are those that will succeed and thrive.

The post Why are enterprises slow to adopt machine learning? appeared first on Artificial Intelligence.

Data is big business. As the saying goes, information is power, and this has never been truer than with traditionally hardware-focused companies shifting toward a software-based model. This digital transformation is happening across the board and is causing enterprises around the world to scramble in efforts to better grasp what’s happening on their networks and operations in order to transform their own businesses. As a result of this ongoing transition, the last few years have seen the likes of IBM and Oracle hoovering up application and cloud technology providers, driven by a need to offer end-to-end services for their customers.

Cisco’s $3.7 billion acquisition of AppDynamics earlier this year is a recent example — the latest in a long line of major tech brands betting big on application and network management technology in the age of IP. And while this has primarily been a change we are seeing in the enterprise space, it’s holding implications for the future of the telecoms sector too.

The Current State of Play

Digital Transformation (DX) continues to sweep across all industry sectors, driving the fundamental shift from physical to digital assets. Underpinning DX is the conversion towards an information-driven economy in which data is the new currency and almost all aspects of business are rooted in software. Nowhere is this more applicable than in telecom. The shift experienced by telcos has already included the move to 4G, supporting and encouraging data-hungry applications and high-bandwidth traffic. This has been great for the subscriber, who has experienced much faster speeds and better connectivity. For the operator, however, it has posed a problem.

Operators face the complex challenges of slow business growth and ongoing disruption to their core services by OTT players and new market entrants, as well as having to manage the mobile data explosion and network expansion — all while providing a consistent subscriber experience. These challenges have created a disconnect between the significant investments operators have made in 4G LTE and the decline in revenues they’ve seen thereafter.

The reality is that physical infrastructure is already being stretched in attempts to accommodate subscriber capacity demands, yet updating or expanding this architecture is a difficult and costly process. A related challenge is the sheer amount of network data that operators now need to store, process and manage as a result of meeting subscriber demands, which was supposed to be mitigated by the move to 4G. But it seems that move may actually be contributing to the problem.

New Data Demands, New Operator Challenges

4G networks, like 3G, are IP-based. However, unlike 3G,  the 4G networks also use IP for voice data. Having a common platform for all network traffic was supposed to make things run smoother, but the complexity grew and the volume of data operators had to accommodate grew substantially. As a result, the industry has been looking ahead to 5G in the hopes it will help alleviate capacity demands. But with 5G, there will be the added pressure to deliver a consistent quality of experience in an environment that forever demands higher data throughput. The volume of network data that operators will need to accommodate will also increase substantially.

Fortunately, there is light at the end of the tunnel in the form of the broader digital ecosystem and new commercial opportunities opening up to operators. With those opportunities come greater expectations from the network and new challenges for delivering on the next stage of CSPs’ digital transformation journeys. In order to meet expectations, and to create a setting in which it becomes possible for mobile operators to embrace new business models and innovate in the use of new technology for delivering new services, a new approach will be needed in terms of network design. Network design could drive DX efforts, but only if operators approach it in the right way.

The Future Will Be Virtualized

Proprietary hardware alone is simply not capable, or economic, when it comes to supporting 5G. The deployment of this technology will be enabled through network functions virtualization (NFV) and software defined networking (SDN).
