AI System – Using Neural Networks With Deep Learning – Beats Stock Market in Simulation

Posted by in categories: finance, information science, robotics/AI

Researchers in Italy have melded the emerging science of convolutional neural networks (CNNs) with deep learning — a discipline within artificial intelligence — to achieve a system of market forecasting with the potential for greater gains and fewer losses than previous attempts to use AI methods to manage stock portfolios. The team, led by Prof. Silvio Barra at the University of Cagliari, published their findings on IEEE/CAA Journal of Automatica Sinica.

The University of Cagliari-based team set out to create an AI-managed “buy and hold” (B&H) strategy — a system of deciding whether to take one of three possible actions — a long action (buying a stock and selling it before the market closes), a short action (selling a stock, then buying it back before the market closes), and a hold (deciding not to invest in a stock that day). At the heart of their proposed system is an automated cycle of analyzing layered images generated from current and past market data. Older B&H systems based their decisions on machine learning, a discipline that leans heavily on predictions based on past performance.

By letting their proposed network analyze current data layered over past data, they are taking market forecasting a step further, allowing for a type of learning that more closely mirrors the intuition of a seasoned investor rather than a robot. Their proposed network can adjust its buy/sell thresholds based on what is happening both in the present moment and the past. Taking into account present-day factors increases the yield over both random guessing and trading algorithms not capable of real-time learning.

Discovery Sheds New Light on Famous Einstein Ring

Social distance science made possible with public W. M. Keck Observatory and NASA archive data.

Determined to find a needle in a cosmic haystack, a pair of astronomers time traveled through archives of old data from W. M. Keck Observatory on Mauankea in Hawaii and old X-ray data from NASA’s Chandra X-ray Observatory to unlock a mystery surrounding a bright, lensed, heavily obscured quasar.

This device could provide cheap electricity to billions living in the dark

Posted by in categories: solar power, sustainability

The thermoelectric generator harnesses the flow of heat between two surfaces — one exposed to the cold sky at night. It could be the nocturnal cousin of solar power, lighting the lives of the 1.7 billion people worldwide living with an unreliable electricity connection.

Theoretical breakthrough shows quantum fluids rotate

Posted by in categories: innovation, quantum physics

If a drop of creamer falls from a spoon into a swirling cup of coffee, the whirlpool drags the drop into rotation. But what would happen if the coffee had no friction—no way to pull the drop into a synchronized spin?

Out-of-sync brain waves may underlie learning deficit linked to schizophrenia

Posted by in category: neuroscience

A new UC San Francisco study has pinpointed a specific pattern of brain waves that underlies the ability to let go of old, irrelevant learned associations to make way for new updates. The research is the first to directly show that a particular behavior can be dependent on the precise synchronization of high-frequency brain waves in different parts of the brain, and might open a path for developing interventions for certain psychiatric disorders, including schizophrenia.

Carnegie Mellon tool automatically turns math into pictures

Posted by in categories: information science, mathematics

Some people look at an equation and see a bunch of numbers and symbols; others see beauty. Thanks to a new tool created at Carnegie Mellon University, anyone can now translate the abstractions of mathematics into beautiful and instructive illustrations.

Animals that can do math understand more language than we think

Posted by in categories: food, mathematics, sustainability

It is often thought that humans are different from other animals in some fundamental way that makes us unique, or even more advanced than other species. These claims of human superiority are sometimes used to justify the ways we treat other animals, in the home, the lab or the factory farm.
