Lifelong Learning Starting From Zero
Strannegård, Claes, Carlström, Herman, Engsner, Niklas, Mäkeläinen, Fredrik, Seholm, Filip Slottner, Chehreghani, Morteza Haghir
We present a deep neural-network model for lifelong learning inspired by several forms of neuroplasticity. The neural network develops continuously in response to signals from the environment. In the beginning, the network is a blank slate with no nodes at all. It develops according to four rules: (i) expansion, which adds new nodes to memorize new input combinations; (ii) generalization, which adds new nodes that generalize from existing ones; (iii) forgetting, which removes nodes that are of relatively little use; and (iv) backpropagation, which fine-tunes the network parameters. We analyze the model from the perspective of accuracy, energy efficiency, and versatility and compare it to other network models, finding better performance in several cases.
In Hindsight: A Smooth Reward for Steady Exploration
Jomaa, Hadi S., Grabocka, Josif, Schmidt-Thieme, Lars
In classical Q-learning, the objective is to maximize the sum of discounted rewards through iteratively using the Bellman equation as an update, in an attempt to estimate the action value function of the optimal policy. Conventionally, the loss function is defined as the temporal difference between the action value and the expected (discounted) reward, however it focuses solely on the future, leading to overestimation errors. We extend the well-established Q-learning techniques by introducing the hindsight factor, an additional loss term that takes into account how the model progresses, by integrating the historic temporal difference as part of the reward. The effect of this modification is examined in a deterministic continuous-state space function estimation problem, where the overestimation phenomenon is significantly reduced and results in improved stability. The underlying effect of the hindsight factor is modeled as an adaptive learning rate, which unlike existing adaptive optimizers, takes into account the previously estimated action value. The proposed method outperforms variations of Q-learning, with an overall higher average reward and lower action values, which supports the deterministic evaluation, and proves that the hindsight factor contributes to lower overestimation errors. The mean average score of 100 episodes obtained after training for 10 million frames shows that the hindsight factor outperforms deep Q-networks, double deep Q-networks and dueling networks for a variety of ATARI games.
Neural networks and deep learning
Why are deep neural networks hard to train? Appendix: Is there a simple algorithm for intelligence? If you benefit from the book, please make a small donation. I suggest $5, but you can choose the amount. Thanks to all the supporters who made the book possible, with especial thanks to Pavel Dudrenov. In the last chapter we learned that deep neural networks are often much harder to train than shallow neural networks. That's unfortunate, since we have good reason to believe that if we could train deep nets they'd be much more powerful than shallow nets. But while the news from the last chapter is discouraging, we won't let it stop us. In this chapter, we'll develop techniques which can be used to train deep networks, and apply them in practice. We'll also look at the broader picture, briefly reviewing recent progress on using deep nets for image recognition, speech recognition, and other applications. And we'll take a brief, speculative look at what the future may hold for neural nets, ...

Unlocking the full potential of artificial intelligence in PH
It was a year ago when we at Microsoft claimed that 2018 would be the year of artificial intelligence (AI). Indeed, 2018 was a remarkable year for AI where we witnessed this game-changing technology dominating the agendas of leading organizations and even nations. How is AI shaping up in 2019? How will the organizations that have deployed AI reap its benefits? To help answer these questions, we partnered with leading research analyst firm IDC to conduct a study involving 109 business leaders and 100 workers in the Philippines.
North Korea university to teach artificial intelligence, state media says
North Korea is reforming education at universities to place greater emphasis on artificial intelligence, according to state media. Pyongyang's Workers' Party newspaper Rodong Sinmun reported Sunday Pyongyang University of Computer Science is changing its computer-programming department into a department for the study of AI. The goal is to improve the quality of school courses so classes on AI are more readily available in the department, according to the report. PyongyangUniversity of Computer Science has decided to improve artificial intelligence education because AI is a "key technology in the information industry," the Rodong article said. The university is developing the new program following directives from Kim Jong Un, issued at the fourth plenum of the seventh party central committee meeting in April, state media said.
Even identical twins don't react the same way to the same foods -- which is why most diet advice doesn't work
Dietary advice seems to change every decade. Fat is bad, then suddenly it's good again. Nowadays, for many people, carbs are the enemy. But it turns out that healthy dietary guidelines can't be boiled down into simple rules. A new crop of studies, which leverage the latest health testing and machine learning technologies, are finding that there's no single diet that works for everyone.

Khan is a migration specialist with 16 years experience in the industry. He is an immigration consultant in Canada accredited with Immigration Consultants of Canada Regulatory Council (ICCRC). Khan specializes in Canadian immigration that includes: Refugee, Investors, Entrepreneur, Temporary Foreign Worker program and Employment Specific Training. Over the years, Khan has held Canadian immigration and recruitment offices here in Canada along with U.A.E, New Zealand, Taiwan, Pakistan and the Philippines processing Canadian immigration cases and facilitating Canadian employers with job-specific trained staff that were later integrated though federal immigration system or provincial nominee programs that resulted in permanent residency which paved the way to citizenship. He also established Continental Career Training Ltd., which is a multi-disciplined, online education training company that has existed for more than 10.5 years.
Bill Gates, Stephen Hawking get AI voice clones, thanks to Facebook engineers
Using Artificial Intelligence, two Facebook engineers have now successfully cloned the voices of famous personalities including Microsoft cofounder Bill Gates, late theoretical physicist Stephen Hawking, and American actor George Takei among few others. Mike Lewis and Sean Vasquez, the two Facebook engineers developed a computer generated speech system called MelNet using Artificial Intelligence. Not just the voices of famous personalities, they have also created voice and music samples using AI. In a recently published research paper, they mentioned relying on machine learning for the convincing AI generated voice clips. Apart from Bill Gates, Stephen Hawking, and George Takei, others whose voice have been cloned are – primatologist Jane Goodall, professors Daphne Koller, Fei Fei Li, scientist Stephen Wolfram and Khan Academy founder Sal Khan.
Are Artificial Intelligence Devices Safe for Kids? - The Tech Edvocate
Artificial intelligence has the potential to the way that kids learn. With its personalized, highly adaptive, multi-sensory nature, it can bring an immediacy to the learning experience that engages students and stimulates their memories in much more powerful ways than traditional classroom learning does. Nevertheless, many parents and educators alike worry about the safety of these devices. In short, artificial intelligence devices are safe as long as we remember their limitations. A key risk factor in the use of AI is the fact that even sophisticated artificial intelligence devices are always at risk of hacking techniques that can manipulate them to act in undesirable ways.
