Hackers are increasingly using this technique, known as steganography, to trick internet users and smuggle malicious payloads past security scanners and firewalls. That doesn't mean people can't discover attacks that use steganographic techniques and learn from how they work. What's clear is that instead of being reserved for the most sophisticated hacks, steganography now crops up in malvertising, phishing, run-of-the-mill malware distribution, and exploit kits (like a tool called Sundown that is popular with hackers looking to exploit software vulnerabilities). "Steganography in cyber attacks is easy to implement and enormously tough to detect, so cyber criminals are shifting towards this technique."
This should include social engineering training and the use of AI/machine learning in your environment. Then, add a tool that gives you a holistic view of your entire network in real time that identifies advanced threats, including those stealthy, unconventional, silent attackers. Whereas cyber attackers in years past have struck quickly and loudly as part of a virtual sneak attack, today's cyber criminals are taking it much more slowly and methodically. Threat detection is certainly a main focus of today's AI and machine learning technology push.
After making sure the model output was reasonable I then trained on my own data set. As an experiment, I trained for 200 some odd epochs until the accuracy did get very high, but the model began outputting lines it had seen before. It became clear that the network might not be large enough to get higher accuracy but it seemed reasonable enough to begin the second round of training on the pickup line data using the weights from the model trained on Twitter data. Sometimes the simple approach works good enough.
My first recollection of an effective Deep Learning system that used feedback loops where in "Ladder Networks". In an architecture developed by Stanford called "Feedback Networks", the researchers explored a different kind of network that feeds back into itself and develops the internal representation incrementally: In an even more recently published research (March 2017) from UC Berkeley have created astonishingly capable image to image translations using GANs and a novel kind of regularization. The major difficulty of training Deep Learning systems has been the lack of labeled data. So the next time you see some mind boggling Deep Learning results, seek to find the strange loops that are embedded in the method.
The growth of Artificial Intelligence is helped by growth in computer power, storage, cloud computing which allows computing power and storage to be shared, Big data which allows efficient search in large sets of data stored in different formats, advancement in statistical techniques etc. As per World Bank's website's data for 2010, only 3 per cent of High Income countries' working population worked in this sector as compared to 45 per cent of Low and Middle Income countries. As per World Bank's website's data for 2010, 74 per cent of High Income countries' working population worked in this sector as compared to 34 per cent in Low and Middle Income countries. But they would slowly but steadily displace humans from variety of roles that humans perform today creating massive disruption in employment.
The new incremental learning technique developed by DeepMind called Transfer Learning allows a standard reinforcement-learning system to build on top of knowledge previously acquired -- something humans can do effortlessly. Lo (2004) states that the satisficing point is obtained through an evolutionary trial and error and natural selection -- individuals make a choice based on past data and experiences and make their best guess. According to Rosenberg, the existing methods to form a human collective intelligence do not even allow users to influence each other, and when they do that they allow the influence to only happen asynchronously -- which causes herding biases. Both of them use large populations of simple excitable units working in parallel to integrate noisy evidence, weigh alternatives, and finally reach a specific decision.
One segment of work in AI is on artificial neural networks--AI that operate (in a very rudimentary manner) how a human brain would. Data is entered into the chip in the form of a laser beam split into four smaller beams--the brightness of each beam as it enters represents an unique number (distinct piece of input information) and the brightness at exit represents a different but unique number (or the distinct piece of information processed). Though old-school, transistor-based processing had a higher 92% success rate, the optical neural network did the task much faster and much more efficiently. If the kinks are worked out to achieve a higher success rate, the photonic chip can unlock phenomenal potential for AI--a photonic neural network in an autonomous car, for instance, can process information in a minute fraction of the time that the AI in such cars take today.
With this more collaborative approach to the evolution of AI, we may finally begin to see the personalization of artificial intelligence, and a great proliferation of new AI programs with idiosyncratic personalities, temperaments, and even intellectual outlooks. Such extraordinary capabilities will be the natural sequel to the new advances in machine learning, natural language processing, and pattern recognition that will finally beget more empathic and intuitive AI programs. And in 2017, we can expect even greater strides in machine learning, as massive upgrades to parallel processing power enable the networks to crunch ever-larger blocks of data. Harry Shrum, Executive Vice President of Microsoft's AI and Research Group, is cheerfully optimistic about AI's outlook in the coming year: "In 2017 we'll see increased acceleration in the democratization of AI for every person and every organization.
Two key scenarios are possible: transforming infrastructure from a set of under-utilized capital assets to a highly efficient set of operational resources through dynamic provisioning based on consumption; and the identification of configurations, dependencies and the cause/effect of usage patterns through correlation analysis. When a user expresses a demand for an IT service, the resources needed to provide that service will be dynamically provisioned from an available pool of capacity to fulfill the demand in real-time. Whether this is network capacity or compute Virtual Machine size – machine learning will enable analysis of the patterns of behavior by users and correlate them to the consumption of infrastructure resources. Automated discovery combined with behavioral correlation analysis will virtually eliminate the need for manual inventory and mapping of components and configuration items in the IT ecosystem to reveal how the ecosystem is operating.
For instance, as customers traverse a business's service channels, network analysis metrics like betweenness centrality can identify "choke points" that customers are commonly funneled through. As an example, these kinds of metrics can identify important patterns, such as cases where automated emails are key points of customer engagement. But beyond communication pattern analysis, AI approaches based on NLU (Natural Language Understanding) offer insight into the communications themselves. AI based on NLU provides opportunities to distill, and quantify, the meaningful aspects of natural language interactions (emails, call transcriptions, etc.)
