[Netease smart news April 17 news] Every year about 20 million people die of cardiovascular disease. Fortunately, researchers at the University of Nottingham, UK, have developed a machine-learning algorithm that can predict the likelihood of you having a heart attack or stroke that is even more accurate than human doctors.
The American Heart Association and the American Heart Association have developed a series of guidelines for assessing the risk of cardiovascular disease in patients, based primarily on eight factors, including age, cholesterol level, and blood pressure. In general, the accuracy of this system prediction can reach 72.8%. This is quite accurate, but Stephen Weng and his team think it can make it better.
They established four computer learning algorithms and then provided them with data from 378,256 patients in the United Kingdom. For the first time, the system uses approximately 295,000 records to generate internal prediction models, and then uses the remaining records to test and refine them. The results of this algorithm are significantly better than those of the American Heart Association and the American Heart Association, and their accuracy varies from 74.5% to 76.4%.
The accuracy of the detection results of the neural network algorithm is the highest, which is 7.6% higher than the existing guidance standard, and false alarms are also reduced by 1.6%. In the test record of 83,000 patients, this system may save 355 more. Interestingly, artificial intelligence systems do not recognize many risk factors and predictors, such as severe mental illness and oral corticosteroids.
Weng said: "There are many interactions in biological systems. This is the reality of the human body. What computer science can do is explore the connections between them."

A single-phase VFD, also known as a variable frequency drive, is a specialized electronic device used for precise control and regulation of single-phase motors. Unlike three-phase motors that are commonly used in industrial applications, single-phase motors are predominantly found in residential and small-scale applications.
The primary function of a single-phase VFD is to control the frequency and voltage supplied to the single-phase motor, thereby enabling accurate regulation of motor speed. By adjusting the frequency and voltage output, the VFD allows for smooth and precise control over the motor's rotational speed. This feature is particularly useful in applications where speed control is required, such as in residential HVAC systems, small-scale machinery, and household appliances.
Energy efficiency is a significant advantage offered by single-phase VFDs. By adjusting the motor speed to match the load requirements, the VFD reduces energy wastage and improves overall energy efficiency. When the motor operates at a lower speed during periods of low demand, energy consumption is significantly reduced, resulting in energy savings and lower operating costs.
Motor protection is another important aspect addressed by single-phase VFDs. They incorporate various protective features, including overload protection, short circuit detection, and thermal protection, which help safeguard the motor against damage due to excessive current, voltage fluctuations, or overheating. This ensures reliable motor operation, prolongs the motor's lifespan, and reduces the risk of unexpected failures.
Harmonic filtering is also a critical consideration in single-phase VFD applications. When single-phase VFDs operate, they can introduce harmonics into the power supply, which may cause issues such as voltage distortions and interference with other electrical equipment. To mitigate these problems, single-phase VFDs often incorporate harmonic filtering techniques to suppress harmonics and ensure a clean and stable power supply, maintaining power quality and preventing damage to connected equipment.
Control algorithms play a significant role in single-phase VFD operation. These algorithms allow for precise control and adjustment of motor speed, ensuring smooth acceleration, deceleration, and accurate speed regulation. Advanced control algorithms enable efficient motor operation and enhance overall system performance.
In summary, single-phase VFDs provide precise control and regulation of single-phase motors in residential and small-scale applications. With their energy efficiency, motor protection features, harmonic filtering capabilities, and advanced control algorithms, single-phase VFDs enhance motor performance, reduce energy consumption, and ensure reliable operation in various residential and small-scale applications.
