A linear, or axial, color gradient. In color science, a color gradient (also known as a color ramp or a color progression) specifies a range of position-dependent colors, usually used to fill a region. In assigning colors to a set of values, a gradient is a continuous colormap, a type of color scheme.
Pantone 448 C is a colour in the Pantone colour system. Described as a "drab dark brown" and informally dubbed the "ugliest colour in the world", it was selected in 2012 as the colour for plain tobacco and cigarette packaging in Australia, after market researchers determined that it was the least attractive colour.
This difference in gradient magnitude might introduce instability in the training process, slow it, or halt it entirely. [1] For instance, consider the hyperbolic tangent activation function. The gradients of this function are in range [-1,1]. The product of repeated multiplication with such gradients decreases exponentially.
