A recent experiment showed an artificial intelligence agent beating the 1980s classic Q* Bert in an unprecedented way. It found a bug that crashed the game at certain points. Training AI agents to spot unexpected errors in games could be a new way to maintain games.

The researchers collected training data on electrodes implanted in patients’ brains while they solved memory tasks. The same electrodes were then used to stimulate the patient’s neural activity. Such stimulation improved the patients’ ability to remember words by an average of 15 percent.

Google calls the product “smart camera,” because machine learning is deployed on the device to make the experience as simple as possible. Google says that by using machine learning on the device, the device can capture and photograph the moment when the facial expressions of people and pets are most appropriate.

If everything is done according to the rules, image recognition will work well. But these algorithms show their weakness whenever people or sheep (objects to be identified) do something unexpected.

“What does depth mean for neural networks?” Is a basic problem in deep learning theory. The conventional wisdom, supported by theoretical studies, is that adding layers increases expressiveness, but optimization becomes more difficult. However, it turns out that adding depth can sometimes speed up optimization.

Babies are experts at play, with an amazing ability to perform novel structured behaviors in an unstructured environment that lacks clear external reward signals. The authors investigate curiosity-driven intrinsic motivation and propose a network of “world models” that learn to predict the dynamic consequences of agent behavior. At the same time, they trained a separate “self model” that enabled the agent to track the error graph of its own world model and then use the self model against the developing world model.

The authors qualitatively show that ES algorithms have very different performance characteristics than traditional RL algorithms: in some games, they learn to exploit the environment better, while other agents may fall into suboptimal local minima. Therefore, combining their advantages with those of traditional RL algorithms may lead to new advances in existing technologies.

Train the increasingly common problem solvers incrementally, constantly learning to solve new tasks without forgetting previous skills. Problem solvers are single recursive neural networks called ONE and can be trained in a variety of ways, for example, black box optimization, reinforcement learning, artificial evolution, and supervised and unsupervised learning.
