Meeting notes 2024-04-18 (April 2024 AMM Working Session on Raw vs. Derived signals):
- The definition of derived signals is not as straightforward as the definition of raw signals
- Distraction levels of 0% and 100% are clear but what does 66% or 34.5% distracted really mean?
- Should distraction really be represented as a percentage? Or, perhaps an enum?
- Units are one way in which clarity can be achieved
- Requires introspection (ability to ask the model) support in the API or equivalent
- Even if enums are used to "bucketize" or categorize the values, interpretation of what each bucket means is still important or not necessarily clear
- For example, what is a crash and severity of crash can have different interpretations depending on culture, context, etc.
- Same for aggressiveness
- How could we make available information on how a signal is derived?
- Where it may be needed or useful
- How can this be expressed to the user?
- Does it need to be digital?
- Margins of error and calculations may vary in time
- Remaining distance based on fuel consumption varies over time
- Some signals from which a derived signal is generate may become unavailable or become available again
- The rate of incoming signals may affect the derivation
- How do we plan to repesent this?
- Even an OEM may not know how some signals are derived
- The Tier-1 may have their own way of doing the derivation and this is not available to the OEM
- What is a raw signal?
- Is there such a beast?
- Clearly there are some, but perhaps the great majority of signals are derived?
- Would adding all the information discussed above impact simplicity?
- One main goal of VSS is simplicity
- Perhaps less precise definitions of signal values is actually simpler
- Should we define the set of parameters to evaluate in order to decide if a derived signal should be added to the signal catalog?
- Is portability of applications (where they can rely on a "standard" definition of a signal) a concern?
- And therefore should the signal catalog only contain clearly defined signals as opposed to leaving definition to interpretation?
- Options to consider:
- Determine if the signal should be made part of the catalog or left for manufacturers to add using overlays
- Require that signal definitions refer to a standard
- Allow liberal interpretation, but mention in signal definition comments that interpretation is left to the implementation

Meeting notes 2024-03-25:
- Head& Eye
- Franca support
- "Inactive" PRs
- Do we want to close them after a certain time of inactivity, if no-one seems to be interested in driving them forward?
- MoM
- PPB: Have no issue closing if there are no progress. Close things at least not touched in a year
- Stefan: discuss in session, archive or take up
- Ulf: A year
- PPB: But not automatic, check last two
- Adnan: Do it AMM, try to schedule time
- AMM
Meeting notes 2024-03-18:
- AOSP
- VSS vs. VSS-tools compatibility
- Overlay and remove
- Shall new keyword "state" be considered to be part of "std VSS syntax", i.e. described in VSS doc
- Alternative is to consider it just as a VSS-tools-specific feature
- https://github.com/nwesem/vss-tools/pulls
- Adnan: Does not really understand the use of active/inactive
- Daniel: Is it intended only for exporter, or also other function
- Adnan: Inactive/active fills a different purpose, not needed for vss-tools for purpose of removing signals of tree
- Terminology:
- AMM
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?
