Ty of your PSO-UNET strategy against the original UNET. The remainder of this paper comprises of 4 sections and is organized as follows: The UNET architecture and Particle Swarm Optimization, that are the two major components with the proposed system, are presented in Section two. The PSO-UNET which is the combination from the UNET and also the PSO algorithm is presented in detail in Section 3. In Section 4, the experimental benefits of the proposed strategy are presented. Ultimately, the conclusion and directions are provided in Section 5. 2. Background from the Employed Algorithms 2.1. The UNET Algorithm and Architecture The UNET’s architecture is symmetric and comprises of two major components, a contracting path and an expanding path which is often extensively seen as an encoder followed by a decoder,Mathematics 2021, 9, x FOR PEER REVIEWMathematics 2021, 9,4 of4 of2.
