+## A bit about the architecture
+
+The **MIRNet** presents a novel architecture with the collective goals of maintaining high-resolution representations through the entire network, and
+receiving strong contextual information from the low-resolution representations.
+
+The core of this approach is a multi-scale residual block containing the following key elements:
+- parallel multi-resolution convolution streams for extracting multi-scale features
+- information exchange across the multi-resolution streams
+- spatial and channel attention mechanisms for capturing contextual information
+- attention based multi-scale feature aggregation.
