Talk:Advisory System

Martien's feedback

• excellent write-up Druk! thanks
• please see diff for some small changes I've made
• three types of advice:
  • how long is today? 24 hours?
  • can you make it specific please?
• seems to me that type B advice is also a must for first version of Cheetah
• please note that the use of "type A", "type B" etc. can be confusing in the context of diabetes "type 1", "type 2", etc.
• perhaps you can rename them into short, medium and long term advice
• Type A Advice
  • wonder if users want to fill in future food or insulin intake
  • cheetah knows from past experiences what user will do regarding food/insulin intake, right?
• Type B advice:
  • I don't expect Cheetah to search for causes:
    • Cheetah is always up to date.
    • Every new entry or fact fed into Cheetah, causes her to nudge her knowledge and advice accordingly.
    • No searching needs to be done.
• Type C advice:
  • This is way off for the current version of Cheetah; may be some future version.
  • I'm still not happy with the "curve" approach.
    • Cheetah has no knowledge about a curve.
    • Cheetah learns about patterns in food/activity/health/insulin on the fly, getting better in getting better as more facts are entered into Cheetah and become available from peers.
• On Cheetah's behaviour in general:
  • Linda" "I want to eat a chocolate bar now. Can I? And how much insulin do I need te take?" Cheetah: Based on earlier experience, my estimate is that your blood glucose level hovers around 5.0. You may want to check this to be sure. So it's okay to have a chocolate bar. But no more."
  • Linda: "We're having [small] pancakes. I think I'll eat four of them. Some with sugar, some with syrup. How much insulin do I need to take?" Cheetah: "Based on past experiences, inject 23 units of Act Rapid".
  • I'm off to volleyball. Do I need to eat anything now or later? If yes, what and how much?
  • Linda: "I feel like having a hypo. So let me check. Yes! I'm at 2.4. Now what?" Cheetah: "It's 15:20. Have a glass of Fanta and an apple."
  • So, in general the pattern is: Linda: "I'm about to [eat or drink | do] something. Cheetah: [inject | eat or drink] amount unit of [insulin | food or drink].
• Conditions
  • I do not completely understand what you're saying here. Please elaborate on this in a f2f meeting.
• Prediction system types
  • From a software architecture point of view, this calls out for pluggable idependent prediction modules with a well defined interface and a way to combine or merge the feedbacks of each into a single advice to the user; this way, we (or any other innivation) can simply replace the current advisory system with a better one later.
• Model Performance
  • Right, so if you make these criteria more precise and measurable, we can use them to evaluate the options and make a choice.
