Multi-Scale Context Aggregation by Dilated Convolutions

Read Paper

What is the mathematical formula of a dilated convolution (k∗lf)t\left(k \ast_{l} f\right)_t?

(k∗lf)t=∑τ=−∞∞kτ⋅fτ−lt\left(k \ast_{l} f\right)_t = \sum_{\tau=-\infty}^{\infty} k_\tau \cdot f_{\tau - lt}, where ll is the dilation factor.

l=1l = 1 equals a normal convolution

What is a different name for a dilated convolution?

Atrous convolution.

What is a different name for an **atrous **convolution?

**Dilated **convolution.

If this images demonstrates a normal convolution, visualize how a dilated convolution l=2l = 2 would look like. 0oX5IPr7TlVM2NpEU.gif
