Apple Machine Learning studies how to mix scarce target-domain data with abundant generic data during language-model pretraining. Across more than 2,000 training runs, the research examines the trade-off between insufficient target exposure, repeated examples, diminishing returns, and overfitting.
A Reddit discussion examines the risks of grouping underrepresented classes into a catch-all category in multiclass classification. It questions whether heterogeneous labels distort decision boundaries and whether rare classes should instead be handled through out-of-distribution detection or excluded from training.
Amazon Bedrock AgentCore now supports Policy Authoring, which converts natural-language policy documents into Dogwood policies. The update helps teams enforce agent controls, including new time-based constraints, with worked examples and best practices.
AWS Professional Services uses a multi-agent framework on Amazon Bedrock AgentCore to automate enterprise cloud migrations end to end. Specialized agents cover discovery, infrastructure-as-code generation, portfolio governance, and post-migration operations, reducing IaC development time from weeks to minutes.
Serval has made Catalyst generally available as an administrative super agent that discovers repetitive work and builds governed enterprise automations. It can also create background agents that monitor connected systems, identify emerging issues, and suggest fixes before employees submit tickets.
Nvidia announced full-scale production of its Spectrum-X Ethernet Photonics co-packaged optical switch for AI factories, using 200G-per-lane links. SK hynix simultaneously published a CPO technology roadmap targeting over 100 Tb/s per node, sub-1 pJ/bit energy consumption, and sub-10 ns chip-to-chip latency.
Merck與Moderna宣布，個性化腫瘤疫苗intismeran autogene在黑色素瘤III期試驗中取得陽性結果，與PD-1抑制劑聯用可顯著改善無復發生存期及無遠處轉移生存期。該療法利用患者腫瘤突變資料與AI篩選新生抗原，為每位患者製作專屬mRNA疫苗。
MiniMax Design uses an Agent to orchestrate multiple models for professional content production. Its positioning reflects a broader shift in AI video competition from model capabilities alone toward integrated products and measurable commercial value.
Moderna and Merck reported that a personalized mRNA therapy, intismeran, combined with Keytruda met key recurrence and distant-metastasis survival endpoints in a prespecified interim analysis. The approach uses AI to select up to 34 tumor-specific neoantigens for an individually manufactured treatment.
Amazon Bedrock AgentCore Web Search now supports per-request domain and publication-date filters. Developers can control which websites agents use and require fresher sources, with filtering enforced server-side.
