<p>You can add new features to any existing sensors (see list below) by adding a new provider in three steps:</p>
<ol>
<li><a href="#modify-the-configyaml-file">Modify</a> the <code>config.yaml</code> file </li>
<li><a href="#create-a-feature-provider-script">Create</a> your feature provider script</li>

<p>As a tutorial, we will add a new provider for <code>PHONE_ACCELEROMETER</code> called <code>VEGA</code> that extracts <code>feature1</code>, <code>feature2</code>, <code>feature3</code> with a Python script that requires a parameter from the user called <code>MY_PARAMETER</code>.</p>

<p>Create your feature Python or R script called <code>main.py</code> or <code>main.R</code> in the correct folder, <code>src/feature/[sensorname]/[providername]/</code>. RAPIDS automatically loads and executes it based on the config key <code>[SRC_SCRIPT]</code> you added in the last step. For our example, this script is:

<p>The next step is to implement the code that computes your behavioral features in your provider script&rsquo;s function. As with any other script, this function can call other auxiliary methods, but in general terms, it should have three stages:</p>
<details class="info"><summary>1. Read a participant&rsquo;s data by loading the CSV data stored in the file pointed by <code>sensor_data_files</code></summary><div class="highlight"><pre><span></span><code><span class="n">acc_data</span> <span class="o">=</span> <span class="n">pd</span><span class="o">.</span><span class="n">read_csv</span><span class="p">(</span><span class="n">sensor_data_files</span><span class="p">[</span><span class="s2">&quot;sensor_data&quot;</span><span class="p">])</span>
</code></pre></div>
<p>Note that the phone&rsquo;s battery, screen, and activity recognition data are given as episodes instead of event rows (for example, start and end timestamps of the periods the phone screen was on)</p>
</details>
<details class="info"><summary>2. Filter your data to process only those rows that belong to <code>time_segment</code></summary><p>This step is only one line of code, but keep reading to understand why we need it.
<div class="highlight"><pre><span></span><code><span class="n">acc_data</span> <span class="o">=</span> <span class="n">filter_data_by_segment</span><span class="p">(</span><span class="n">acc_data</span><span class="p">,</span> <span class="n">time_segment</span><span class="p">)</span>
</code></pre></div></p>
<p>You should use the <code>filter_data_by_segment()</code> function to process and group those rows that belong to each of the <a href="../../setup/configuration/#time-segments">time segments RAPIDS could be configured with</a>.</p>
<p>Let&rsquo;s understand the <code>filter_data_by_segment()</code> function with an example. A RAPIDS user can extract features on any arbitrary <a href="../../setup/configuration/#time-segments">time segment</a>. A time segment is a period that has a label and one or more instances. For example, the user (or you) could have requested features on a daily, weekly, and weekend basis for <code>p01</code>. The labels are arbitrary, and the instances depend on the days a participant was monitored for: </p>
<ul>
<li>the daily segment could be named <code>my_days</code> and if <code>p01</code> was monitored for 14 days, it would have 14 instances</li>
<li>the weekly segment could be named <code>my_weeks</code> and if <code>p01</code> was monitored for 14 days, it would have 2 instances.</li>
<li>the weekend segment could be named <code>my_weekends</code> and if <code>p01</code> was monitored for 14 days, it would have 2 instances.</li>
</ul>
<p>For this example, RAPIDS will call your provider function three times for <code>p01</code>, once where <code>time_segment</code> is <code>my_days</code>, once where <code>time_segment</code> is <code>my_weeks</code>, and once where <code>time_segment</code> is <code>my_weekends</code>. In this example, not every row in <code>p01</code>&lsquo;s data needs to take part in the feature computation for either segment <strong>and</strong> the rows need to be grouped differently. </p>
<p>Thus <code>filter_data_by_segment()</code> comes in handy, it will return a data frame that contains the rows that were logged during a time segment plus an extra column called <code>local_segment</code>. This new column will have as many unique values as time segment instances exist (14, 2, and 2 for our <code>p01</code>&lsquo;s <code>my_days</code>, <code>my_weeks</code>, and <code>my_weekends</code> examples). After filtering, <strong>you should group the data frame by this column and compute any desired features</strong>, for example:</p>
<div class="highlight"><pre><span></span><code><span class="n">acc_features</span><span class="p">[</span><span class="s2">&quot;maxmagnitude&quot;</span><span class="p">]</span> <span class="o">=</span> <span class="n">acc_data</span><span class="o">.</span><span class="n">groupby</span><span class="p">([</span><span class="s2">&quot;local_segment&quot;</span><span class="p">])[</span><span class="s2">&quot;magnitude&quot;</span><span class="p">]</span><span class="o">.</span><span class="n">max</span><span class="p">()</span>
</code></pre></div>
<p>The reason RAPIDS does not filter the participant&rsquo;s data set for you is because your code might need to compute something based on a participant&rsquo;s complete dataset before computing their features. For example, you might want to identify the number that called a participant the most throughout the study before computing a feature with the number of calls the participant received from that number.</p>
</details>
<details class="info"><summary>3. Return a data frame with your features</summary><p>After filtering, grouping your data, and computing your features, your provider function should return a data frame that has:</p>
<ul>
<li>One row per time segment instance (e.g., 14 our <code>p01</code>&lsquo;s <code>my_days</code> example)</li>
<li>The <code>local_segment</code> column added by <code>filter_data_by_segment()</code></li>
<li>One column per feature. The name of your features should only contain letters or numbers (<code>feature1</code>) by convention. RAPIDS automatically adds the correct sensor and provider prefix; in our example, this prefix is <code>phone_accelerometr_vega_</code>.</li>
</ul>
