Module ciphercore_base::ops

Implementation of several custom operations. A custom operation can be thought of as a polymorphic function, i.e., where the number of inputs and their types can vary.

Modules

• adder
  Binary adder that adds two bitstrings.
• auc
  AUC score metric, functionally equivalent to sklearn.metrics.roc_auc_score.
• clip
  Clip function that returns a given value if it is inside of the interval [0,2^k] and clips values outside this interval to its edges.
• comparisons
  Various comparison functions for signed and unsigned integers including greater-than, less-than, greater-than-equal-to, less-than-equal-to, equal, not-equal.
• fixed_precision
• goldschmidt_division
  Division via the Goldschmidt method.
• integer_key_sort
  Sort by integer key.
• inverse_sqrt
  Inverse square root approximation via the Newton-Raphson method.
• long_division
  Long division for bitstrings of arbitrary length.
• min_max
  Minimum and maximum operations. They operate on unsigned integers represented as bitstrings.
• multiplexer
  Multiplexer (Mux) operation that takes three inputs a, b, c and returns b if a is 1 or c if a is 0.
• newton_inversion
  Multiplicative inversion via the Newton-Raphson method.
• pwl
• taylor_exponent
  Exp(x) approximation relying on Taylor series expansion.
