Deep learning based multimodal urban air quality prediction and traffic analytics
An overview of the proposed methodology is provided by Fig. 3, which can be roughly divided into six phases comprising Data Collection (Phase 1); Data Pre-Processing (Phase 2); Sensor Fusion (Phase 3); training the Deep Learning Model (Phase 4); Prediction (Phase 5); and AQI calculation (Phase 6). In the first phase, multi-modal real-time data (including…

Smart home energy management and power trading optimization using an enhanced manta ray foraging optimization
The goal of this paper is to develop a design for future smart grids that will reduce power costs for residential users, stabilize the system, and reduce peak load across the board. Several smart devices with varying operational times and power ratings are included in the smart home. The solar panel and wind turbine make…

OpenAI’s chief scientist helped to create ChatGPT — while worrying about AI safety
This story is part of Nature’s 10, an annual list compiled by Nature’s editors exploring key developments in science and the individuals who contributed to them. As a teenager, Ilya Sutskever knocked on Geoffrey Hinton’s door at the University of Toronto in Canada and asked for a job. “He said he was cooking fries to…

the AI system was a force in 2023 — for good and bad
Credit: Olga Yastremska/Alamy, Gabby Jones/Bloomberg via Getty This story is part of Nature’s 10, an annual list compiled by Nature’s editors exploring key developments in science and the individuals who contributed to them. It co-wrote scientific papers — sometimes surreptitiously. It drafted outlines for presentations, grant proposals and classes, churned out computer code, and served…

MIT researchers observe a hallmark quantum behavior in bouncing droplets | MIT News
In our everyday classical world, what you see is what you get. A ball is just a ball, and when lobbed through the air, its trajectory is straightforward and clear. But if that ball were shrunk to the size of an atom or smaller, its behavior would shift into a quantum, fuzzy reality. The ball…

Semisupervised hyperspectral image classification based on generative adversarial networks and spectral angle distance
The proposed method (SADGAN) was tested and compared with four hyperspectral datasets: the University of Pavia dataset, the Indian Pines dataset, the Salinas dataset related to agriculture, and the Tianshan dataset related to geological bodies. The first hyperspectral dataset is Indian Pines, which was acquired by the airborne visible/infrared imaging spectrometer (AVIRIS) sensor over the…

Improving the efficiency of using multivalued logic tools: application of algebraic rings
The scheme considered below is intended to demonstrate the following fundamental circumstance, which is expressed by formula (26). It is possible to represent the element of the ring in the “hybrid” number system, formula (20). The digits of this number, if the operations proceed within the corresponding ring, can be handled independently. This approach can…

Using broadband infrastructure as a social sensor to detect inequities in unemployment during the COVID-19 pandemic
Mainline results for broadband: asymmetries in broadband access increase unemployment Before discussing the results, we must first define empirically our key variable, namely what we mean by broadband access. We start with the definition used by the Federal Communications Commission (FCC) which states that broadband is “high-speed internet access that is always on and faster than…
