assignments-filename clj

centroids-filename clj

change-extension clj

(change-extension filename format)

csv-seq-filename->format-seq clj

(csv-seq-filename->format-seq k-means-state key)

Converts a csv file into another file type and returns a k means object with an updated key name.

CSV isn't a well optimized format for doing large computations.
Computing the min and max of each column working with optimized csv seqs can take two orders of magnitude longer than the same operations performed against arrow streams.

dataset-seq->column-names clj

(dataset-seq->column-names ds-seq)

ds-seq->rows->maps clj

(ds-seq->rows->maps ds-seq rows)

extension clj

(extension filename)

Returns a filenames last file extension.

file? clj

(file? filename)

Returns true if a file exists and false otherwise.

filename->format clj

(filename->format filename)

Parses a format lookup key from a filename.

formats clj

Supported file formats for reading and writing datasets.

generate-filename clj

(generate-filename prefix)

read-centroids-from-file clj

(read-centroids-from-file k-means-state)

read-dataset-seq clj

(read-dataset-seq k-means-state key)

Loads the dataset at the file path in key.

write-dataset-seq clj

(write-dataset-seq k-means-state key dataset)
