LeAP: Learnable Adaptive Permutation for Feature Selection in Heterogeneous and Sparse Recommender Systems

arXiv:2606.01111v2 Announce Type: replace Abstract: Modern industrial recommender systems rely on thousands of heterogeneous features -- ranging from low-dimensional scalars (e.g., statistical value) to high-dimensional embeddings (e.g., user-id embeddings, MLP representations) -- to achieve high-precision predictions. Given the immense computational costs associated with training, efficient feature selection is critical. However, existing methods encounter three primary bottlenecks: (1)...

new Abstract: Modern industrial recommender systems rely on thousands of heterogeneous features -- ranging from low-dimensional scalars (e.g., statistical value) to high-dimensional embeddings (e.g., user-id embeddings, MLP representations) -- to achieve high-precision predictions. Given the immense computational costs associated with training, efficient feature selection is critical. However, existing methods encounter three primary bottlenecks: (1) they typically assume uniform feature...

TAMUNA: Doubly Accelerated Distributed Optimization under Partial Participation

arXiv:2302.09832v4 Announce Type: replace Abstract: In distributed optimization and federated learning, slow and costly communication between parallel devices and the central server constitutes the primary bottleneck. To alleviate this burden, two strategies have emerged: 1) local training (LT), which reduces communication frequency by performing multiple local computations between rounds, and 2) compression (CC), which consists of transmitting lower-dimensional, compact representations....

Number of teachers in England’s state schools drops for second year in row

Despite Labour’s promises to increase recruitment, school census shows a fall of nearly 2,000 teachers since last yearThe number of teachers working in England’s state schools has shrunk for the second year in a row, even as the government said it was meeting its promises to increase recruitment where needed. The annual school workforce census shows there are 466,300 teachers in state schools this year, a fall of more than 1,900 since last year due to declining numbers in mainstream primary...

A prognostic human brain network for diffuse midline glioma

Abstract Diffuse midline gliomas (DMGs) are near-universally lethal tumours of the childhood central nervous system1,2. In animal models, DMGs form brain-wide integrated networks through neuron-to-glioma synapses3,4,5,6 and glioma-to-glioma gap junctional coupling3. This extensive connectivity robustly promotes the growth and invasion of DMG3,4,5,6,7,8,9 and other glial malignancies10,11,12 through paracrine mechanisms and direct neuron-to-glioma synapses.

Strengthening the UK primary healthcare response to suicidal ideation

Suicide claims 720 000 lives globally annually,1 with the UK alone seeing roughly 20 deaths by suicide each day.2 Effective suicide prevention requires action at all levels, including from government, local authorities, businesses and community groups, but crucially how suicidal ideation is assessed and managed in frontline primary healthcare. For some patients primary care might be the first point of contact to discuss feelings about suicide, offering an opportunity for early intervention...

Commentary: If your child’s myopia keeps getting worse, having new spectacles isn’t enough

Commentary: If your child’s myopia keeps getting worse, having new spectacles isn’t enough Slowing the progression of myopia in children early may matter far more than we realise for their lifelong eye health, says Dr Foo Li Lian. SINGAPORE: When I tell parents that their young child’s spectacle prescription has increased again within a year, they are sometimes almost too calm about it. They see it as simply “updating glasses” annually and making the child sit farther from the television or...

Wemby vows revival after Spurs 'let that one go'

Victor Wembanyama accepted responsibility for his role in San Antonio's first Game 1 loss in the NBA Finals in franchise history but said he isn't "worried in the slightest" about how the Spurs will fare as the series unfolds. Minutes after the visiting New York Knicks defeated San Antonio 105-95 on Wednesday to take a 1-0 lead in the NBA Finals, Wembanyama, who committed postseason career highs in turnovers (6) and missed shots (15), agreed with coach Mitch Johnson's assessment that he...

Event-Based Vision in Space: Applications, Trends, and Future Directions

arXiv:2606.01280v1 Announce Type: new Abstract: Earth Observation (EO) is undergoing a significant transformation driven by the deployment of novel sensing technologies. Traditional frame-based optical sensors often struggle with motion blur, high power consumption, and extreme data redundancy in challenging orbital environments. In contrast, event-based sensors, also known as neuromorphic cameras, offer a bio-inspired asynchronous approach.
