TOPICS FOR DISCUSSION: Raw vs. derived signals; does VSS need to define or state how signals are derived? Is this useful to clients? For signals derived through ML; should confidence level, variance, precision, error, etc. be reported? Is this useful to clients? How should model-generated derived signals such as "driver attentiveness" be represented (in the absence of a standard)? Confidence percentage? Enum? To what level of specificity should VSS describe signals? Leave semantics to OEMs (flexibility for OEMs but affects portability) or define them precisely?
