Tree-of-Thoughts lets a model explore many reasoning paths in parallel, like branches of a tree, instead of committing to one line of thought.
TechnicalGraph-of-Thoughts models reasoning as a network where thoughts can merge, loop, and connect freely, not just branch.
IndustriesAI in insurance underwriting uses machine learning to assess risk and price policies faster and more granularly than manual review.
ApplicationsAI in wildfire detection spots smoke and flames from cameras and satellites within minutes, far faster than human lookouts.
ApplicationsAI in crop disease diagnosis identifies plant diseases from leaf photos, helping farmers act before an outbreak spreads.
Language AIALiBi (Attention with Linear Biases) is a clever way to give transformers a sense of word order without traditional position embeddings.
Language AIMulti-Query Attention (MQA) is a memory-saving twist on transformer attention that shares one set of keys and values across all attention heads.
Language AISentencePiece is a language-agnostic tokenizer that learns how to split raw text into subword pieces directly from data, without relying on spaces.
ApplicationsAI reads dense medical records and complex trial eligibility rules to connect patients with studies they qualify for.
ApplicationsAI reads clinical notes and automatically assigns the standardized billing and diagnosis codes that hospitals use to get paid and track care.
ApplicationsAI scans vast streams of satellite photos to automatically detect, count, and track objects and changes on Earth's surface, far faster than humans could.
Audio AIAcoustic echo cancellation (AEC) is the technology that stops you from hearing your own voice bounce back during a call.
