                        Normal distribution.
bags_to_tfidf           Computes a TF-IDF weight vectors for a set of
                        word bags.
cosine_dist             Computes the cosine distance between numeric
                        vectors (1 minus cosine similarity).
cosine_sim              Computes the cosine distance value between a
                        bag of words and a set of TF-IDF weight
                        vectors.
early_abandoned_dist    Finds the Euclidean distance between points, if
                        distance is above the threshold, abandons the
                        computation and returns NAN.
ecg0606                 A PHYSIONET dataset
euclidean_dist          Finds the Euclidean distance between points.
find_discords_brute_force
                        Finds a discord using brute force algorithm.
find_discords_hotsax    Finds a discord (i.e. time series anomaly) with
                        HOT-SAX. Usually works the best with lower
                        sizes of discretization parameters: PAA and
                        Alphabet.
find_discords_rra       Finds a discord with RRA (Rare Rule Anomaly)
                        algorithm. Usually works the best with higher
                        than that for HOT-SAX sizes of discretization
                        parameters (i.e., PAA and Alphabet sizes).
idx_to_letter           Get the ASCII letter by an index.
is_equal_mindist        Compares two strings using mindist.
is_equal_str            Compares two strings using natural letter
                        ordering.
letter_to_idx           Get the index for an ASCII letter.
letters_to_idx          Get an ASCII indexes sequence for a given
                        character array.
manyseries_to_wordbag   Converts a set of time-series into a single bag
                        of words.
min_dist                Computes the mindist value for two strings
paa                     Computes a Piecewise Aggregate Approximation
                        (PAA) for a time series.
sax_by_chunking         Discretize a time series with SAX using
                        chunking (no sliding window).
sax_distance_matrix     Generates a SAX MinDist distance matrix (i.e.
                        the "lookup table") for a given alphabet size.
sax_via_window          Discretizes a time series with SAX via sliding
                        window.
series_to_chars         Transforms a time series into the char array
                        using SAX and the normal alphabet.
series_to_string        Transforms a time series into the string.
series_to_wordbag       Converts a single time series into a bag of
                        words.
str_to_repair_grammar   Runs the repair on a string.
subseries               Extracts a subseries.
znorm                   Z-normalizes a time series by subtracting its
                        mean and dividing by the standard deviation.
