DeepMind, a subsidiary of Google, talked about the experiment with testing artificial intelligence models on generalization skills and abstract thinking. Specialists have developed a generator that formulates questions based on the notion of progression, color properties, shapes or sizes and their interrelationships. Similar tasks are encountered in IQ tests for people.

Most models answered questions with an accuracy of 75%. At the same time, researchers found a strict correlation between the effectiveness of tasks and the ability to identify the underlying abstractions. They managed to increase efficiency by training algorithms to explain their answers, to show what interrelations and properties should be considered in one or another issue.

However, in some models it is difficult to "transfer" the studied relationships to new properties, for example, if it trained to identify logical sequences relative to the color of objects, and in the task it is required to establish the dependence on their form.

The team found out that if the neural network correctly extrapolated its knowledge of the relationship to a new combination of values, then the accuracy of the tasks was increased to 87%. In the case of incorrect extrapolation, it fell to 32%.

Samsung has completed the development and testing of a new memory module standard LPDDR5. The chip is created using a 10-nanometer process technology and has a capacity of 8 GB. LPDDR5 DRAM is planned to be used in the production of smartphones with support for mobile communication 5G, on-board electronics of cars, as well as solutions for AI based on mobile platforms.

One of the innovations of LPDDR5 technology is improved energy efficiency. According to the company, the chip consumes 30% less electricity compared to the previous generation of LPDDR4X memory chips. The number of memory banks (subsections of the DRAM cell) is increased from 8 to 16 to provide high speed with low power consumption. In active mode, the module lowers the operating voltage to synchronize with the application processing speed.

Also, the new chip implements an advanced "deep sleep mode" to reduce the power consumption level to half the level of "standby" in LPDDR4X memory modules.

In the new LPDDR5 chip, the data transfer rate is increased to 6400 Mbit / s, which is 1.5 times more than the last LPDDR4X chips. According to Samsung, the module allows to transfer the volume in 51.2 GB of data (14 films with the size of 3.7 GB each as a Full-HD) in just 1 second.

The chip is scheduled to be launched in mass production as soon as the LPDDR5 specification is approved.
