Topic Extraction

No algorithm description given

Topics extraction with Non-Negative Matrix Factorization This is a proof of concept application of Non Negative Matrix Factorization of the term frequency matrix of a corpus of documents so as to extract an additive model of the topic structure of the corpus. The output is a list of topics, each represented as a list of terms (weights are not shown). The default parameters (n_samples / n_features / n_topics) should make the example runnable in a couple of tens of seconds. You can copy this algorithm and try to increase the dimensions of the problem, but be aware than the time complexity is polynomial. Taken from:

Internet access

This algorithm has Internet access. This is necessary for algorithms that rely on external services, however it also implies that this algorithm is able to send your input data outside of the Algorithmia platform.

To understand more about how algorithm permissions work, see the permissions documentation.
