class MicroGrad::Value(T)

• MicroGrad::Value(T)
• Reference
• Object

Overview

Stores a single scalar value and its gradient

Defined in:

micrograd/engine.cr

Class Method Summary

• .[](num : Number)

  Initialize a Value(T) with a Number; useful for casting different scalars into a Value

Instance Method Summary

• #*(other : Value)

  Multiply this Value with another and return the result as a Value chained with the inputs.

• #*(other : Number)

  Multiple this Value with any Number (internally wrapping that in a Value) and return the result as a Value chained with the inputs.

• #**(other : Number)

  Calculate this value's data to the power of the given scalar and return the result as a Value chained with the inputs.

• #+(other : Value)

  Add this Value to another and return the result as a Value chained with the inputs.

• #+(other : Number)

  Add this Value to any Number (internally wrapping that in a Value) and return the result as a Value chained with the inputs.

• #-(other : Value)

  Subtract another Value from this one and return the result as a Value chained with the inputs.

• #-(other : Number)

  Subtract any Number from this Value (internally wrapping that in a Value) and return the result as a Value chained with the inputs.

• #-

  Negate this Value and return the result as a Value chained with the inputs.

• #/(other : Value)

  Divide this Value by another and return the result as a Value chained with the inputs.

• #/(other : Number)

  Divide this Value by any Number (internally wrapping that in a Value) and return the result as a Value chained with the inputs.

• #backward

  Calculate the gradients backwards from this Value

• #data : T
• #data=(value : Number)

  Assign a data value

• #draw_dot(io, graph_name = "X")

  Generate a Graphviz dot digraph diagram to the io; the output can be converted to an image using the dot tool.

• #exp

  Power of e

• #grad : T
• #grad=(value : Number)

  Assign a gradient

• #log

  Natural log

• #relu

  ReLU

• #sigmoid

  Sigmoid

• #tanh

  tanh

• #to_s(io)

  Return a string describing the data and gradient of this Value
