Useful Links.This section contains test procedures for measuring, pursuant to EPCAthe energy efficiency of any small, large, or very large commercial package air-conditioning and heating equipmentpackaged terminal air conditioners and packaged terminal heat pumps, computer room air conditionersvariable refrigerant flow systemsand single package vertical air conditioners and single package vertical heat pumps.

The omitted sections of the test procedures listed in Table 1 of this section must not be used. Any representations made with respect to the energy use or efficiency of such packaged terminal air conditioners and heat pumps must be in accordance with whichever version is selected. A manufacturer who elects to use an optional compressor break-in period in its certification testing should record this information including the duration in the test data underlying the certified ratings that is required to be maintained under 10 CFR The only additional specifications that may be used in setting up the basic model for test are those set forth in the installation and operation manual shipped with the unit.

Each unit should be set up for test in accordance with the manufacturer installation and operation manuals.

Paragraphs e 1 through 3 of this section provide specifications for addressing key information typically found in the installation and operation manuals. If a rated air flow value for testing is not clearly identified, a value of standard cubic feet per minute scfm per ton shall be used. The manufacturer 's representative will be allowed to inspect and discuss set-up only with a DOE representative and adjust only the modulating components during testing in the presence of a DOE representative that are necessary to achieve steady-state operation.

Only previously documented specifications for set-up as specified under paragraphs d and e of this section will be used. For packaged terminal air conditioners and packaged terminal heat pumps, the unit must be installed in a wall sleeve with a 14 inch depth if available. If a 14 inch deep wall sleeve is not available, use the available wall sleeve option closest to 14 inches in depth. The area s between the wall sleeve and the insulated partition between the indoor and outdoor rooms must be sealed to eliminate all air leakage through this area.

No specific level of water mineral content or water temperature is required for the water added to the condensate drain pan. For packaged terminal air conditioners and packaged terminal heat pumps, the indoor filter used during testing shall be the standard or default filter option shipped with the model.

If a particular model is shipped without a filter, the unit must be tested with a MERV-1 filter sized appropriately for the filter slot. Please help us improve our site!

Each field in your source is automatically assigned an id that you can later use as a parameter in models and predictions.

In the Models Section you will learn how to customize the input fields or the objective field. You can use this id to retrieve the prediction later on. The predicted value is found in the prediction object, keyed by the corresponding objective field id. A quick start guide for the impatient is here.

You can use BigML. That is to say, using BigML. Fully white-box access to your datasets, models, clusters and anomaly detectors. Asynchronous creation of resources.

The four original BigML resources are: source, dataset, model, and prediction. As shown in the picture below, the most basic flow consists of using some local (or remote) training data to create a source, then using the source to create a dataset, later using the dataset to create a model, and, finally, using the model and new input data to create a prediction.

The training data is usually in tabular format. Each row in the data represents an instance (or example) and each column a field (or attribute).

These fields are also known as predictors or covariates. When the machine learning task to learn from training data is supervised one of the columns (usually the last column) represents a special attribute known as objective field (or target) that assigns a label (or class) to each instance.

The training data in this format is named labeled and the machine learning task to learn from is named supervised learning. Once a source is created, it can be used to create multiple datasets. Likewise, a dataset can be used to create multiple models and a model can be used to create multiple predictions. A model can be either a classification or a regression model depending on whether the objective field is respectively categorical or numeric. Often an ensemble (or collection of models) can perform better than just a single model.

Thus, a dataset can also be used to create an ensemble instead of a single model. A dataset can also be used to create a cluster or an anomaly detector.

Clusters and Anomaly Detectors are both built using unsupervised learning and therefore an objective field is not needed. In these cases, the training data is named unlabeled. A centroid is to a cluster what a prediction is to a model. Likewise, an anomaly score is to an anomaly detector what a prediction is to a model.

There are scenarios where generating predictions for a relative big collection of input data is very convenient. For these scenarios, BigML. These resources take a dataset and respectively a model (or ensemble), a cluster, or an anomaly detector to create a new dataset that contains a new column with the corresponding prediction, centroid or anomaly score computed for each instance in the dataset.
