All things change, and you must adapt over time. Ongoing monitoring of machine learning fraud detection systems is imperative for success. As populations and the underlying data shift, expected system inputs degrade and therefore have an impact on overall performance. This isn't unique to machine learning systems; rule-based systems have the same challenge. But newer machine learning methods can adapt to new and unidentified patterns as underlying changes occur. This eliminates some, but not all, of the machine learning retraining and evaluation steps.

Stephen Hawking said, "The development of full artificial intelligence could spell the end of the human race….It would take off on its own, and re-design itself at an ever increasing rate. Humans, who are limited by slow biological evolution, couldn't compete, and would be superseded." Ever since its genesis, there have been conflicting views and concerns on the potential enhancement or doom that it can cause to human civilization. While some experts believe that this technology will advance and augment our intelligence, some like Bill Gates have expressed concerns on how a machine's intelligence becomes strong enough to be a concern. For now, let's take a look at the current trends of AI and where it is headed to in 2018: If 2017 was the year where the warnings from Elon Musk and Stephen Hawking about the potential evil from AI clashed with predictions from Mark Zuckerberg and Bill Gates on its potential good, 2018 will be the year when the debate shifts to its practical utility.

When you search for security data science on the internet, it's difficult to find resources with crisp and clear information about the use cases, methods and limitations in Information Security (hereby referred to as InfoSec). There's usually always some marketing material attached to it. So, I thought of summarising my knowledge and InfoSec experience in this article. When the attackers are within the enterprise network, they first need to figure out where they are. Once they accomplish this, they move towards their targets, and carry out the attack.

If you want to see data being put hard at work, look no further than artificial intelligence and machine learning – never before has timely, accurate data been so critical. A recent survey released by Narrative Science finds 61 percent of enterprises have already implemented AI within their businesses. At least 71 percent said AI was part of their enterprises' innovation strategies. At the same time, 90 percent of respondents in the business intelligence function reported that they would be interested in incorporating AI to make their data and analytics tools smarter. At the same time, AI and machine learning are not overnight projects in themselves – they take considerable time and expertise to get rolling, and constantly need refreshing and updating.

Machine learning has had fruitful applications in finance well before the advent of mobile banking apps, proficient chat bots, or search engines. Given high volume, accurate historical records, and quantitative nature of the finance world, few industries are better suited for artificial intelligence. There are more uses cases of machine learning in finance than ever before, a trend perpetuated by more accessible computing power and more accessible machine learning tools (such as Google's Tensorflow). Today, machine learning has come to play an integral role in many phases of the financial ecosystem, from approving loans, to managing assets, to assessing risks. Yet, few technically-savvy professionals have an accurate view of just how many ways machine learning finds its way into their daily financial lives.

For roughly a decade, the SEO industry has been consistently moving further away from discussions about the internal workings of the search engines, starting around the time of the first Panda update. This decision to focus on more strategic and long-term SEO approaches has been a positive one, overall. Marketing strategies built entirely on the whims of a search engine aren't built to stand the test of time. However, there's no denying the value that came from understanding and predicting how search engines would react to certain kinds of tweaks to the HTML or to the backlink profile in the early days of SEO. Most of us have assumed that those days ended when Google embraced machine learning.

However, this reasoning is based on the assumption that once a machine learning algorithm has been developed to solve one problem, that same algorithm can be easily applied to solve a different problem.

It is standard practice in managing payments to block potentially fraudulent transactions via a set of rules. These rules can be very effective in mitigating fraud risk, and practitioners in the industry are comfortable with this approach. Quite often these rules are able to mitigate the losses from fraudulent transactions without producing a correspondingly high alarm rate. For example, a fraud team might create rules based on a location and block transactions from risky zip codes. They might also create rules to block transactions from cards used too frequently by blocking any transactions for cards with more than 4 previous transactions in the past 30 minutes.

Commerce has evolved from its many different forms – from in-store purchases and mail order businesses to online market places and omni-channel commerce. Digital downloads and instant fulfillment services like Uber are transforming the way people consume goods and services. Online shopping has slowly eroded the traditional brick and mortar space of shopping malls. Consumers' retail trips in November and December, the two biggest shopping months out of the year, dropped from 35 billion visits in 2010 to 17.3 billion visits in 2013, according to a report from Cushman & Wakefield. In spite of rapid rise and adoption of modern commerce, fraud prevention is still based on archaic methods that are rigid, resource constrained and time consuming.
