[2019-03-13] Whatā€™s the best sleep tracking device? Whoā€™s actually looked into the science of how it works? /r/Biohackers

The EEG headbands are the most accurate by far. Dreem and Phillips Smartsleep. All the wristband actigraphy stuff has pretty poor correlations with actual lab results. They're good for knowing how long you slept and HRV but the error margins on individual sleep phases are pretty bad.

[2019-11-16] Best way to quantify/rank subjective attributes? /r/QuantifiedSelf [[dashboard]] [[hpi]]

> Also, what do you want to use these sorted elements for? It's great if it's just for the sake of it too! But wondering if you're trying to find some cool correlations or something :)

Its a recurring problem in my project ideas where the dataset involves subjective attributes.

For example, one my ideas is creating a software that collects data about your personal day(hours slept, food eaten, medication taken, physical exercise, etc etc) and success metrics(money earned, how productive you are being, fat loss/muscle gain, etc etc) and give the user the correlations between the success metrics and the data describing the days, so the user have a 100% empirical and domain-blind feedback on what works for them. Kinda like what [this](https://medium.com/@mikebechtel/i-tracked-every-single-thing-i-ate-for-a-full-year-here-are-10-quick-a-has-2c259dd2f57b) guy did, but nicely packaged into a single software.

Then theres a lot of attributes that are too subjective(specially some of the success metrics), so having a consistent and methodical way of collecting this data would be useful. Also I have no idea if someone is working on something similar, would love to read some papers/articles about it so I can mature my ideas, see what works and what doesn't.

However, recently developed optically pumped magnetometers8,9,10,11 (OPMs) offer a means to measure the small magnetic fields generated by the brain12,

[2019-03-04] Quantified Mind Archives - Quantified Self

http://quantifiedself.com/quantified-mind/ 

here was no single formula but one principle that comes up a lot is to change the difficulty of the test dynamically based on the userā€™s accuracy, to reach a steady state of some fixed accuracy, and apply Bayesian estimation to the parameters of interest. For example, in Digit Span we estimate the level in which the user would get exactly 50% of the trials correct. The reason that our verbal learning test doesnā€™t use a fixed number of items is that some people would find 10 items too hard and others would find 30 too easy, so any fixed number would waste a lot of their time testing them at an inappropriate level.

[2019-10-28] The value of tracking data /r/running (motivation)

I love data. I love technology.  I love running.  I've got a crap ton of available data on virtually everything having to do with my running/health.  I have a high end Garmin watch, I run with my heart rate strap w/ Garmin Run Dynamics, I have a Stryd power meter, i used to track my HRV every morning, etc.

And it's almost all useless.  The more I've run, the more I've realized how little of it really matters.  Sure you can track your progress any number of ways.  My favorite, RE ratio (basically the amount of running power required for a given pace) very cleanly shows how much my efficiency has improved over long periods of time, but I can also look at long run pace for a given HR, resting HR, implied VO2Max, etc. etc. etc.  Or I could just look at old fashioned race times and see how they compare.

Almost all of this data is descriptive (and sometimes it isn't even meaningful) and it's almost never prescriptive.  The value of descriptive stats is minimal, beyond perhaps for some ongoing motivation to see improvement at regular intervals in the absence of races.  I really think tracking your mileage, pace, perceived exertion, and interval/workout details (when relevant) to be the key factors that are necessary.  It really doesn't take much to collect and track those.

So much of the data collected has false precision (just because a number is being spit out, doesn't mean it has inherent meaning or is accurate), and even more of it is useless without very detailed context.  Heart rate is the best example of this: the temperature, humidity, wind, your fatigue, whether you're sick, what you're wearing, if you had caffeine, if you ate before running, if you had a few beers the day before, etc. will all massively impact your HR on a given run.  Not to mention that people really need to know their max hr, min hr, vo2max hr, and lactate threshold hr for zones to have any meaning... and almost no one knows these numbers.

I have my training plan, and nothing really changes what i'm going to be running on a given day beyond how my body subjectively feels.

[2019-10-28] The value of tracking data /r/running [[motivation]]

I'm interested in the process of quantified self and gathering information of your body with the help of wearable technology. It'd be interesting to hear from the community, what got you into quantified self and what for you is the value you get from it? What keeps you motivated to gather information or what made you stop?

At the moment I track my running pace and recovery times. I use the information to set a goal for each workout and plan them according to my energy levels. One of my friends is very organized in this sense and has tracked nearly all his runs this year. I've learned a great deal from him but I'd like to know more and understand what other ways there are to make use of the data that's out there.

[2020-10-22] analog to digital - comparison between Fourier transform and autocorrelation function - Signal Processing Stack Exchange

Therefore for random signals, the Fourier transform will not exist and their spectral density cannot be computed that way. Nevertheless, for such signals an indirect description, based on an autocorrelation measure, can also be defined, whose advantage being that the Fourier transform of it may exist. Therefore the PSD of a random process is defined as the Fourier transform of its ACF.

fitness tracker accuracy

online trackers: crap, quite obviously

wearables: use HR to estimate oxygen consumption. but the algos doing that are oversimplified. typically, error is about 20%.

to measure really accurately, you put people in a multi-million dollar chamberā€¦

Garmin VivoSmart HR+ here! I had the first VivoSmart and wore it to death so an upgrade to the new HR+ was made! I asolutely love it! Has everything I need as a keen runner! Heart rate, and GPS seem very accurate and it never fails to record data or connect to my phone, unlike my SO's fitbit, which she finds a nightmare! She is considering the purchase of Garmin after seeing mine.
My two kids have Garmin's too, the VivoFit Jr for my 6yo son and the VivoActive for my 10yo daughter. Both just as reliable and as fun as mine! Have fun!!

fitbit

  • doesn’t really detect HR consistently.
  • doesn’t detect that you stopped weering it and flashes with green light
  • sometimes woudn’t record sleeps
  • sleep phases are weird

[2019-04-29] How to track multi-day hikes? Best GPS watch / unit with longest battery life? /r/CampingGear [[qs]] [[gps]]

I really like GPS Logger on Android. It's really simple, highly configurable, and open source. Plus, it's not like I'm using my phone anyway. Setting it at 10-30 second intervals in airplane mode will last me a couple days. I haven't found a watch that won't break the bank that can do that.

https://play.google.com/store/apps/details?id=com.mendhak.gpslogger

It's just GPS points though. If you want to see them on map, you'll have to open it in a map program. I use GPX Viewer, but I don't think it's anything extra special. I also upload them automatically when I get internet again to Google Drive and Dropbox.

I pretty much have used my phone for everything since smart phones have been a thing. They are the ultimate multipurpose devices. I've never really felt the need or been able to justify things like smart watches, E-Readers, Cameras (once smartphones hit 5mp or so).

I tracked everything I ate for the last year, along with my exercise, sleep, vitals, and sense of well-being. I'm just starting to analyze the 500,000+ data points, but here are 10 quick blink reactions:
Full Article Here:
[https://medium.com/@mikebechtel/i-tracked-every-single-thing-i-ate-for-a-full-year-here-are-10-quick-a-has-2c259dd2f57b?source=friends\_link&sk=ed6113272876d866eeaa23ec05415495](https://medium.com/@mikebechtel/i-tracked-every-single-thing-i-ate-for-a-full-year-here-are-10-quick-a-has-2c259dd2f57b?source=friends_link&sk=ed6113272876d866eeaa23ec05415495)

tl/dr here:

1. Exercise is a Heckuva Anti-Depressant.
2. Sugar & Salt hangovers: Nearly as bad as alcohol hangovers.
3. Two Days of Bad Sleep in a Row Will Mess. You. Up.
4. Weight Loss != Fat Loss
5. Carbs aren't evil. But they're... sneaky.
6. 15% body fat (for a guy) is doable with tasty food. 10% requires you to eat fewer tasty things. 5% requires you to forgo taste (and friends) entirely.
7. Muscles recover strongest 2-3 days after a workout, and stay stronger-than-baseline for about 2-3 days after that. Beyond that, wimpy-ness resumes and you atrophy. (Which is why consistency is key.)
8. Food Scales are your Friend. Casseroles, stews, and buffets are your Enemy.
9. Processed foods are easiest to track (because they have SKU's) but not as good for you. Whole Foods vs. Whole Data.
10. Standard McDonald's Cheeseburgers are, as far as I can tell, the most nutritionally complete food on a macronutrient-per-dollar basis.

https://www.reddit.com/r/Biohackers/comments/9780qa/finally_received_my_gen_2_oura_ring_with_some/e46dqtd/ 

 Received my ring last Friday. Had the 1st gen but returned it due to inaccurate sleep readings. Unfortunately, the new ring seems to be inaccurate for me as well. Both rings read that I was asleep when I was meditating, laying awake in bed, or even making coffee. Since the Readiness score is based in part on the Sleep score thatā€™s inaccurate, too. I contacted customer service last night, no word back yet.
The new material of the 2nd gen ring feels cheap and plasticky, although a better size and weight than the 1st gen. Overall, so far, not impressed. Especially after waiting over 9 months. But I look forward to my initial impressions changing for the better with continued use. Would love to hear from other Ōura users as well.
