3. A system for using machine learning to accurately predict outcomes of large-scale cable fire tests, comprising:
a test chamber in which the large-scale cable test is administered on a set of large-scale cables in accordance with NFPA 262 cable testing requirements;
a cone calorimeter configured to administer (i) a small-scale cable fire test on a set of small-scale cables, and (ii) the small-scale cable fire test on an additional small-scale cable;
a processor;
a memory; and
a non-transitory computer-readable memory interfaced with the processor and the memory, and storing instructions thereon that, when executed by the processor, cause the processor to:
obtain a first set of results of the large-scale cable fire test administered on the set of large-scale cables, the first set of results comprising, for each of the set of large-scale cables, a max flame spread distance, a peak optical density, and an average optical density,
obtain a second set of results of the small-scale cable fire test administered on the set of small-scale cables, the second set of results comprising, for each of the set of small-scale cables, a diameter, a peak heat release rate, a total heat release, a heat of combustion, a total smoke metric, and an ignition time,
clean the first set of results and the second set of results to remove incomplete data, conflicting data, and erroneous data, resulting in a set of cleaned data,
segment the set of cleaned data between a training dataset and a validation dataset, wherein the training dataset at least partially overlaps with the validation set,
train a plurality of machine learning models using the training dataset, wherein the plurality of machine learning models are of different types,
input the validation dataset into each machine learning model of the plurality of machine learning models to determine a machine learning model of the plurality of machine learning models that is most accurate in assessing how a given large-scale version of a given small-scale cable would perform on the large-scale cable fire test,
obtain an additional set of results of the small-scale cable fire test on the additional small-scale cable, the additional set of results comprising, for the additional small-scale cable, an additional diameter, an additional peak heat release rate, an additional total heat release, an additional heat of combustion, an additional total smoke metric, and an additional ignition time,
input the additional set of results into the most accurate machine learning model, and
after inputting the additional set of results into the most accurate machine learning model, output a result from the most accurate machine learning model, the result (i) comprising at least one of: an average optical density output, a peak optical density output, or a max flame spread distance output, and (ii) predicting an outcome of a large-scale version of the additional small-scale cable tested according to the large-scale cable fire test.
