TokenomicsThe unit economics of AI usage, measuring cost per token against productivity produced.TraceabilityThe ability to follow an AI decision back to the data and logic behind it.Traditional AIEarlier AI built on explicitly programmed rules, logic, and human-written knowledge rather than learning from data.Training dataThe examples, like text, images, or audio, used to teach a machine learning model how to do its task.TransformerThe neural network architecture behind modern AI. It uses attention to look at all parts of the input at once instead of one piece at a time.Transparent AI ReasoningThe design requirement that an AI system articulate its reasoning — what it observed, what that implies, and what published evidence supports the inference — before its output reaches a human decision-maker. Axenya's implementation: every clinical inference surfaces with a reasoning chain and supporting literature citations; inferences the model cannot explain are suppressed entirely. Addresses two risks simultaneously: clinician liability (the physician can see and evaluate the reasoning before acting on it) and AI error rates (unexplained outputs may reflect spurious correlations rather than valid clinical patterns).Turing testA test proposed by Alan Turing in 1950: can a machine hold a conversation well enough that a person can't tell it apart from a human?Uncanny ValleyThe creepy zone where an AI feels almost human and people recoil once they realize it is not.
