 ==== Surprises & Insights ==== ==== Surprises & Insights ====
-  * Unexpected discoveries +  * It's barely deep learning anymore. Much more focus on DSP. 
-  * Hidden complexities +  * I have absolutely no idea what happens with the performance on such small models. One would need a full development cycle for a new sleep staging model, completely decoupled from recent advances in sleep staging.
-  * Simpler alternatives found+
