(Press-News.org) Face attribute classification (FAC) is a high-profile problem in biometric verification and face retrieval. Although recent research has been devoted to extracting more delicate image attribute features and exploiting the inter-attribute correlations, significant challenges still remain.
To solve the problems, a research team led by Na LIU published their new research on 15 June 2024 in Frontiers of Computer Science co-published by Higher Education Press and Springer Nature.
The team proposed a scattering-based hybrid block, termed WS-SE, to incorporate frequency-domain (WST) and image-domain (CNN) features in a channel attention manner. Compared with CNN, WS-SE achieved a more efficient FAC performance and compensated for the model sensitivity of the small-scale affine transform.
In addition, to further exploit the relationships among the attribute labels, the team proposed a learning strategy from a causal view. The cause attributes defined using the causality-related information can be utilized to infer the effect attributes with a high confidence level.
Future work will consider the design of hybrid networks based on non-average integration at different scales and rotations, as well as the direct application of WST to local texture enhancement to achieve lightweight fusion models and improve the performance of FAC.

Risky drinkers most at risk: Ads from sports broadcasts significantly increase alcohol urges
New Edith Cowan University (ECU) research shows exposure to alcohol advertisements during national sports broadcasts, particularly those that feature a preferred beverage, significantly increases cravings in people with risky drinking behaviours.
The ECU study, led by Dr Ross Hollett, analysed nationally televised finals matches from the Australian Football League (AFL) and the National Rugby League (NRL) ...
How to differentially improve the cultivated land quality in China?
2024-07-10
Quality is the core characteristic of cultivated land and is crucial for ensuring sustainable resource utilization and national food security. To meet the increasing demand for food driven by rapid population growth and the continual optimization of dietary structures, the intensity of cultivated land utilization has been steadily increasing. This trend has resulted in degradation issues such as deterioration of black soil, thinning of the cultivated land layer, reduction in organic matter content, soil salinization, acidification, and contamination by heavy metals, all of which threaten national food security. Currently, China has entered a critical period of agricultural ...
Study reveals racial disparities in Huntington’s disease diagnoses
2024-07-10
New research led by UCLA Health revealed that Black patients with Huntington's disease in the U.S. and Canada received their diagnoses, on average, one year later compared to White patients after symptoms first appear.
Huntington’s disease is a rare, incurable genetic disease that causes a gradual death of nerve cells, resulting in a variety of symptoms affecting movement, emotions and cognition. About 41,000 Americans have the disease and 200,000 are at risk of inheriting it, according to the Huntington’s Disease Society of America. Children of a parent with ...
Archaeologists report earliest evidence for plant farming in east Africa
2024-07-10
A trove of ancient plant remains excavated in Kenya helps explain the history of plant farming in equatorial eastern Africa, a region long thought to be important for early farming but where scant evidence from actual physical crops has been previously uncovered.
In a new study published July 10 in the Proceedings of the Royal Society B, archaeologists from Washington University in St. Louis, the University of Pittsburgh and their colleagues report the largest and most extensively dated archaeobotanical record from interior east Africa.
Up until now, scientists have ...
UQ research reveals exercise brain boost can last for years
2024-07-10
A longitudinal study by University of Queensland researchers has found high-intensity interval exercise improves brain function in older adults for up to 5 years.
Emeritus Professor Perry Bartlett and Dr Daniel Blackmore from UQ’s Queensland Brain Institute led the study in which volunteers did physical exercise and had brain scans.
Emeritus Professor Perry Bartlett and Dr Daniel Blackmore have shown high intensity exercise boosts cognition in healthy older adults and the improvement was retained for up to 5 years.
Emeritus Professor Bartlett said it is the first ...
Researchers identify brain region involved in oxycodone relapse
2024-07-10
LA JOLLA, CA—Even years after they have recovered, a person who once struggled with alcohol or opioid addiction can relapse—and that relapse is more likely to occur during particularly stressful times. Now, Scripps Research scientists have identified an area of the brain that plays a key role in stress-induced oxycodone relapse. Their findings explain why the drug suvorexant, which they previously found to reduce alcohol and oxycodone relapse when administered orally, works so well.
“Having a better understanding of the region(s) in the brain responsible for this kind of relapse is incredibly important as we develop treatments for alcohol use disorder and opioid ...
Daily sugar intake fell by 5 g in kids + 11 g in adults year after UK sugar tax imposition
2024-07-10
Daily sugar intake fell by around 5 g in children and by around 11 g in adults in the 12 months following the introduction of the UK’s ‘sugar tax’, formally known as the Soft Drinks Industry Levy, finds an analysis of 11 years of survey data, published online in the Journal of Epidemiology & Community Health.
The sugar from soft drinks alone made up over half this total, the estimates suggest. But overall daily energy intake from free sugars levels are still higher than the updated recommendation from the World Health Organisation (WHO) of 5%---equivalent to 30 g/day for adults, 24 g for 7–10 year olds, and 19 g for 4–6 year olds—point ...
Osteoarthritis may double risk of speedy progression to severe multimorbidity
2024-07-10
Osteoarthritis—a condition in which the protective cartilage on the ends of bones breaks down—may more than double the risk of speedy progression to accumulating severe long term conditions (multimorbidity), finds a 20 year study published in the open access journal RMD Open.
And there seem to be 4 different speeds of progression to multimorbidity, the findings indicate.
Persistently low levels of physical activity, a high calorie diet, plus chronic low grade inflammation may help to explain the link between osteoarthritis and the risk of accumulating other long term conditions, suggest the researchers.
Although the exact causes aren’t known, injury, age, family ...
Researchers listen to the hearts of bats in flight
2024-07-10
Researchers from Konstanz have measured the heart rate of bats over several days in the wild, including complete flights—the first time this has been done for a bat species. To record the heart rate of male common noctule bats during flight, the scientists attached heart rate transmitters weighing less than one gram to the animals, which they then accompanied in an airplane while the bats flew, sometimes for more than an hour, in search of food. Their results, published in Proceedings of the Royal Society B, show how much energy bats consume over the course of a day and what energy-saving strategies they ...
Familial endocrine diseases linked to increased risk of pregnancy loss, new research shows
2024-07-10
Women who have close family members with endocrine diseases, including type 2 diabetes, thyroid diseases and polycystic ovary syndrome (PCOS), are at higher risk of pregnancy loss, a new study has found [1].
The research, presented today at the ESHRE 40th Annual Meeting in Amsterdam, examined the association between various endocrine diseases and the incidence of pregnancy loss. The study investigated 366,539 women in Denmark between 1973 and 2022.
The study found that women with parents diagnosed with endocrine diseases faced a 6% higher risk of pregnancy loss ...
