RAPIDS Features
===============
*How do I compute any of these features?* In your ``config.yaml``, go to the sensor section you are interested in and set the corresponding ``COMPUTE`` option to ``TRUE`` as well as ``DB_TABLE`` to the senor's table name in your database (the default table name is the one assigned by Aware), for example:
| ``MESSAGES:``
| ``COMPUTE: True``
| ``DB_TABLE: messages``
| ``...``
If you want to extract phone_valid_sensed_days.csv, screen features or locaton features based on fused location data don't forget to configure ``TABLES_FOR_SENSED_BINS`` (see below).
.. _global-sensor-doc:
Global Parameters
"""""""""""""""""
.. _sensor-list:
- ``TABLES_FOR_SENSED_BINS`` - Add as many sensor tables as you have in your database. All sensors included are used to compute ``phone_sensed_bins.csv`` (bins of time when the smartphone was sensing data). In turn, these bins are used to compute ``PHONE_VALID_SENSED_DAYS`` (see below), ``episodepersensedminutes`` feature of :ref:`Screen<screen-sensor-doc>` and to resample fused location data if you configure Barnett's location features to use ``RESAMPLE_FUSED``. See TABLES_FOR_SENSED_BINS_ variable in ``config`` file (therefore, when you are extracting screen or Barnett's location features, screen and locations tables are mandatory).
.. _fitbit-table:
- ``FITBIT_TABLE`` - The table in your database that contains your Fitbit data in a field named `fitbit_data` in JSON format.
.. _fitbit-sensors:
- ``FITBIT_SENSORS`` - The list of sensors to be parsed from the fitbit table: ``heartrate``, ``steps``, ``sleep``.
.. _pid:
- ``PID`` - The list of participant ids to be included in the analysis. These should match the names of the files created in the ``data/external`` directory (:ref:`see more details<db-configuration>`).
.. _day-segments:
- ``DAY_SEGMENTS`` - The list of day epochs that features can be segmented into: ``daily``, ``morning`` (6am-12pm), ``afternnon`` (12pm-6pm), ``evening`` (6pm-12am) and ``night`` (12am-6am). This list can be modified globally or on a per sensor basis. See DAY_SEGMENTS_ in ``config`` file.
.. _timezone:
- ``TIMEZONE`` - The time zone where data was collected. Use the timezone names from this `List of Timezones`_. Double check your chosen name is correct, for example US Eastern Time is called New America/New_York, not EST.
.. _database_group:
- ``DATABASE_GROUP`` - The name of your database credentials group, it should match the one in ``.env`` (:ref:`see the datbase configuration<db-configuration>`).
.. _download-dataset:
- ``DOWNLOAD_DATASET``
- ``GROUP``. Credentials group to connect to the database containing ``SENSORS``. By default it points to ``DATABASE_GROUP``.
.. _readable-datetime:
- ``READABLE_DATETIME`` - Configuration to convert UNIX timestamps into readbale date time strings.
- ``FIXED_TIMEZONE``. See ``TIMEZONE`` above. This assumes that all data of all participants was collected within one time zone.
- Support for multiple time zones for each participant coming soon based on the ``timezone`` table collected by Aware.
.. _phone-valid-sensed-days:
- ``PHONE_VALID_SENSED_DAYS``.
Contains three attributes: ``BIN_SIZE``, ``MIN_VALID_HOURS``, ``MIN_BINS_PER_HOUR``.
On any given day, Aware could have sensed data only for a few minutes or for 24 hours. Daily estimates of features should be considered more reliable the more hours Aware was running and logging data (for example, 10 calls logged on a day when only one hour of data was recorded is a less reliable feature compared to 10 calls on a day when 23 hours of data were recorded.
Therefore, we define a valid hour as those that contain a minimum number of valid bins. In turn, a valid bin are those that contain at least one row of data from any sensor logged within that period. We divide an hour into N bins of size ``BIN_SIZE`` (in minutes) and we mark an hour as valid if contains at least ``MIN_BINS_PER_HOUR`` (out of the total possible number of bins that can be captured in an hour based on their length i.e. 60min/``BIN_SIZE`` bins). Days with valid sensed hours less than ``MIN_VALID_HOURS`` will be excluded form the output of this file. See PHONE_VALID_SENSED_DAYS_ in ``config.yaml``.
Note that RAPIDS *DOES NOT* filter your feature files automatically, you need to do this manually based on ``"data/interim/{pid}/phone_valid_sensed_days.csv"``.
You can get access to every phone's sensed bins matrix (days x bins) in ``data/interim/{pid}/phone_sensed_bins.csv``. As mentioned above, RAPIDS uses this file to compute ``phone_valid_sensed_days.csv``, ``episodepersensedminutes`` feature of :ref:`Screen<screen-sensor-doc>` and to resample fused location data if you configure Barnett's location features to use ``RESAMPLE_FUSED``.

Aware Android client stores call types 1=incoming, 2=outgoing, 3=missed while Aware iOS client stores call status 1=incoming, 2=connected, 3=dialing, 4=disconnected. We extract iOS call types based on call status sequences: (1,2,4)=incoming=1, (3,2,4)=outgoing=2, (1,4) or (3,4)=missed=3. Sometimes (due to a possible bug in Aware) sequences get logged on the exact same timestamp, thus 3-item sequences can be 2,3,4 or 3,2,4. Although iOS stores the duration of ringing/dialing stages for missed calls, we set it to 0 to match Android.

frequencyentropy nats The entropy of the used apps within a category during a ``day_segment`` (each app is seen as a unique event, the more apps were used, the higher the entropy). This is especially relevant when computed over all apps. Entropy cannot be obtained for a single app.
================== ========= =============
.. _applications-foreground-observations:
**Assumptions/Observations:**
Features can be computed by app, by apps grouped under a single category (genre) and by multiple categories grouped together (meta categories). For example, we can get features for Facebook, for Social Network Apps (including Facebook and others) or for a meta category called Social formed by Social Network and Social Media Tools categories.
Apps installed by default like YouTube are considered systems apps on some phones. We do an exact match to exclude apps where "genre" == ``EXCLUDED_CATEGORIES`` or "package_name" == ``EXCLUDED_APPS``.
We provide three ways of classifying and app within a category (genre): a) by automatically scraping its official category from the Google Play Store, b) by using the catalogue created by Stachl et al. which we provide in RAPIDS (``data/external/``), or c) by manually creating a personalized catalogue.
The way you choose strategy a, b or c is by modifying ``APPLICATION_GENRES`` keys and values. Set ``CATALOGUE_SOURCE`` to ``FILE`` if you want to use a CSV file as catalogue (strategy b and c) or to ``GOOGLE`` if you want to scrape the genres from the Play Store (strategy a). By default ``CATALOGUE_FILE`` points to the catalogue created by Stachl et al. (strategy b) and you can change this path to your own catalogue that follows the same format (strategy c). In addition, set ``SCRAPE_MISSING_GENRES`` to true if you are using a FILE catalogue and you want to scrape from the Play Store any missing genres and ``UPDATE_CATALOGUE_FILE`` to true if you want to save those scrapped genres back into the FILE.
The genre catalogue we provide was shared as part of the Supplemental Materials of Stachl, C., Au, Q., Schoedel, R., Buschek, D., Völkel, S., Schuwerk, T., … Bühner, M. (2019, June 12).

Barnett’s location features are based on the concept of flights and pauses. GPS coordinates are converted into a
sequence of flights (straight line movements) and pauses (time spent stationary). Data is imputed before features
are computed.

timezone The timezone used to calculate location.
minutes_data_used This is NOT a feature. This is just a quality control check, and if set to TRUE, a new column is added to the output file with the number of minutes containing location data that were used to compute all features. The more data minutes exist for a period, the more reliable its features should be. For fused location, a single minute can contain more than one coordinate pair if the participant is moving fast enough.

Description taken from `Beiwe Summary Statistics`_.
================ ========= =============
Name Units Description
================ ========= =============
hometime minutes Time at home. Time spent at home in minutes. Home is the most visited significant location between 8 pm and 8 am including any pauses within a 200-meter radius.
disttravelled meters Total distance travelled over a day (flights).
rog meters The Radius of Gyration (rog) is a measure in meters of the area covered by a person over a day. A centroid is calculated for all the places (pauses) visited during a day and a weighted distance between all the places and that centroid is computed. The weights are proportional to the time spent in each place.
maxdiam meters The maximum diameter is the largest distance between any two pauses.
maxhomedist meters The maximum distance from home in meters.
siglocsvisited locations The number of significant locations visited during the day. Significant locations are computed using k-means clustering over pauses found in the whole monitoring period. The number of clusters is found iterating k from 1 to 200 stopping until the centroids of two significant locations are within 400 meters of one another.
avgflightlen meters Mean length of all flights.
stdflightlen meters Standard deviation of the length of all flights.
avgflightdur seconds Mean duration of all flights.
stdflightdur seconds The standard deviation of the duration of all flights.
probpause The fraction of a day spent in a pause (as opposed to a flight)
siglocentropy nats Shannon’s entropy measurement based on the proportion of time spent at each significant location visited during a day.
circdnrtn A continuous metric quantifying a person’s circadian routine that can take any value between 0 and 1, where 0 represents a daily routine completely different from any other sensed days and 1 a routine the same as every other sensed day.
wkenddayrtn Same as circdnrtn but computed separately for weekends and weekdays.

If your Aware client was ONLY configured to use GPS set ``location_to_use`` to ``ALL``, if your client was configured to use BOTH GPS and fused location you can use ``ALL`` or set ``location_to_use`` to ``ALL_EXCEPT_FUSED`` to ignore fused coordinates, if your client was configured to use fused location only, set ``location_to_use`` to ``RESAMPLE_FUSED``. ``RESAMPLE_FUSED`` takes the original fused location coordinates and replicates each pair forward in time as long as the phone was sensing data as indicated by ``phone_sensed_bins`` (see :ref:`Phone valid sensed days <phone-valid-sensed-days>`), this is done because Google's API only logs a new location coordinate pair when it is sufficiently different from the previous one.
There are two parameters associated with resampling fused location in the ``RESAMPLE_FUSED_LOCATION`` section of the ``config.yaml`` file. ``CONSECUTIVE_THRESHOLD`` (in minutes, default 30) controls the maximum gap between any two coordinate pairs to replicate the last known pair (for example, participant A's phone did not collect data between 10.30am and 10:50am and between 11:05am and 11:40am, the last known coordinate pair will be replicated during the first period but not the second, in other words, we assume that we cannot longer guarantee the participant stayed at the last known location if the phone did not sense data for more than 30 minutes). ``TIME_SINCE_VALID_LOCATION`` (in minutes, default 720 or 12 hours) the last known fused location won't be carried over longer that this threshold even if the phone was sensing data continuously (for example, participant A went home at 9pm and their phone was sensing data without gaps until 11am the next morning, the last known location will only be replicated until 9am). If you have suggestions to modify or improve this imputation, let us know.
*Significant Locations Identified*
(i.e. The clustering method used)
Significant locations are determined using K-means clustering on locations that a patient visit over the course of the period of data collection. By setting K=K+1 and repeat clustering until two significant locations are within 100 meters of one another, the results from the previous step (K-1) can be used as the total number of significant locations. Taken from `Beiwe Summary Statistics`_.
*Definition of Stationarity*
(i.e., The length of time and distance a person has to be around the same place to be labelled as a pause)
This is based on a Pause-Flight model, The parameters used are a minimum pause duration of 300sec and a minimum pause distance of 60m. See the `Pause-Flight Model`_.
*The Circadian Calculation*
For a detailed description of how this is calculated, see Canzian, L., & Musolesi, M. (2015, September). Trajectories of depression: unobtrusive monitoring of depressive states by means of smartphone mobility traces analysis. In Proceedings of the 2015 ACM international joint conference on pervasive and ubiquitous computing (pp. 1293-1304). Their procedure was followed using 30-min increments as a bin size.

========================= ================= =============
**Assumptions/Observations:**
An ``unlock`` episode is considered as the time between an ``unlock`` event and a ``lock`` event. iOS recorded these episodes reliably (albeit some duplicated ``lock`` events within milliseconds from each other). However, in Android there are some events unrelated to the screen state because of multiple consecutive ``unlock``/``lock`` events, so we keep the closest pair. In our experiments these cases are less than 10% of the screen events collected. This happens because ``ACTION_SCREEN_OFF`` and ``ON`` are "sent when the device becomes non-interactive which may have nothing to do with the screen turning off". Additionally, in Android it is possible to measure the time spent on the ``lock`` screen before an ``unlock`` event as well as the total screen time (i.e. ``ON`` to ``OFF``) but we are only keeping ``unlock`` episodes (``unlock`` to ``OFF``) to be consistent with iOS.

======================== =========== =============
**Assumptions/Observations:**
Only features from summary data are available at the momement.
The `fitbit_with_datetime` rule will extract Summary data (`fitbit_sleep_summary_with_datetime.csv`) and Intraday data (`fitbit_sleep_intraday_with_datetime.csv`). There are two versions of Fitbit's sleep API (`version 1`_ and `version 1.2`_), and each provides raw sleep data in a different format:
- Sleep level. In ``v1``, sleep level is an integer with three possible values (1, 2, 3) while in ``v1.2`` is a string. We convert integer levels to strings, "asleep", "restless" or "awake" respectively.
- Count summaries. For Summary data, ``v1`` contains "count_awake", "duration_awake", "count_awakenings", "count_restless", and "duration_restless" fields for every sleep record while ``v1.2`` does not.
- Types of sleep records. ``v1.2`` has two types of sleep records: "classic" and "stages". The "classic" type contains three sleep levels: "awake", "restless" and "asleep". The "stages" type contains four sleep levels: "wake", "deep", "light", and "rem". Sleep records from ``v1`` will have the same sleep levels as `v1.2` classic type; therefore we set their type to "classic".
- Unified level of sleep. For intraday data, we unify sleep levels of each sleep record with a column named "unified_level". Based on `this Fitbit forum post`_ , we merge levels into two categories:
- For the "classic" type unified_level is one of {0, 1} where 0 means awake and groups "awake" + "restless", while 1 means asleep and groups "asleep".
- For the "stages" type, unified_level is one of {0, 1} where 0 means awake and groups "wake" while 1 means asleep and groups "deep" + "light" + "rem".
- Short Data. In ``v1.2``, records of type "stages" contain "shortData" in addition to "data". We merge both to extract intraday data.
- "data" contains sleep stages and any wake periods > 3 minutes (180 seconds).
- "shortData" contains short wake periods representing physiological awakenings that are <= 3 minutes (180 seconds).
- The following columns of Summary data are not computed by RAPIDS but taken directly from columns with a similar name provided by Fitbit's API: `efficiency`, `minutes_after_wakeup`, `minutes_asleep`, `minutes_awake`, `minutes_to_fall_asleep`, `minutes_in_bed`, `is_main_sleep` and `type`
- The following columns of Intraday data are not computed by RAPIDS but taken directly from columns with a similar name provided by Fitbit's API: `original_level`, `is_main_sleep` and `type`. We compute `unified_level` as explained above.
These are examples of intraday and summary data:
- Intraday data (at 30-second intervals for "stages" type or 60-second intervals for "classic" type)
