# Dense feature

> A feature in which most or all values are nonzero, typically a tensor of floating-point values. For example, the following 10-element Tensor is dense because 9 of its values are nonzero:[^1]

A [feature](https://wiki.g15e.com/pages/Feature%20(machine%20learning.txt)) in which most or all values are nonzero, typically a [tensor](https://wiki.g15e.com/pages/Tensor.txt) of floating-point values. For example, the following 10-element Tensor is dense because 9 of its values are nonzero:[^1]
