<li>
<p>{params}: Map with hyperparameters for special Machine Learning implementation</p>

<li>
<p>{extraAttributes}: Map of attributes with constant values the model shall not be trained with but displayed with the result of the prediction. Possible data types are "numeric" and "class".</p>

<li>
<p>"implementation": String with the name of the implementation you want to use</p>

<li>
<p>{data.features}: Map that assigns the features of the matched data to the types that were defined in the create call</p>

<p>data.label: column with label values of the matched data</p>
</li>
<li>
<p>{features}: Map with features for prediction (for timePeriod == false the feature names again must match the types defined in the create call), there are several ways to define this parameter:</p>
<div class="ulist">
<ul>
<li>
<p>for several predictions at once: {feature1: [f1_value1, f1_value2, …​, f1_valueN], feature2:[f2_value1, f2_value2, …​, f2_valueN], …​}</p>
