Merge DataFrame or named Series objects with a database-style join.
concat
Concatenate danfo objects along a particular axis with optional set logic along the other axes.
getDummies
Convert categorical variable into dummy/indicator variables. Similar to OneHotEncoding
Data Normalization
LabelEncoder
Encode target labels with value between 0 and n_classes-1.
OneHotEncoder
Encode categorical features as a one-hot numeric array.
StandardScaler
Standardize features by removing the mean and scaling to unit variance
MinMaxScaler
Transform features by scaling each feature to a given range
Working with DateTime
toDateTime
Convert argument to datetime.
dateRange
Return a fixed frequency Datetime Index.
Dt
A class that converts strings of Date Time into a usable format, by exposing various helper methods.
Streaming Functions
streamCSV
A function that loads a CSV object as a stream, returning intermediate rows as a DataFrame.
streamJSON
A function that loads a JSON object as a stream, returning intermediate rows as a DataFrame.
streamCSVTransformer
A function that loads a CSV object as a stream, and applies a map-reduce function to intermediate rows.
convertFunctionTotransformer
A function to convert any JS function into a Stream transformer.
Utility and Configurations
Utils
A utility class with helper methods mostly used internally.
Config
Base configuration class for NDframe objects
Strings
Str
A class that converts strings into a usable format, by exposing various helper methods.
Internal Libs
