Struct yata::methods::Conv

pub struct Conv { /* private fields */ }

Convolution Moving Average with specified weights for timeseries of ValueType.

Parameters

Has a single parameter weights: Vec<ValueType>

weights vector’s length must be > 0

Input type

Input type is ValueType

Output type

Output type is ValueType

Performance

O(length(weights))

This method is relatively slow compare to the other methods.
