Survival analysis is a collection of statistical procedures for data analysis for which the outcome variable of interest is time until an event occurs. In survival analysis, ties are sometimes found. Ties can cause problems in establishing the partial likelihood when determining the component of the risk set. Ties can be overcome by using the breslow, efron, and exact. The purpose of this study…
The Demand Robust Counterpard Open Capacitated Vehicle Routing Problem with time windows and deadline (DRC-OCVRPtw,d)model is a garbage transportation model that aims to determine the best route and the fastest time in completing garbage transportation. The model DRC-OCVRPtw,d model that was formed was deemed not simple, so it required a long completion time. This study aims to simplify DRC-OCV…
The addition of layers to the U-Net architecture will cause more parameters and increase network complexity. The Visual Geometry Group (VGG) architecture has the ability to overcome these problems by using a small convolution filter. To overcome excessive feature learning in VGG, Dense Connected (DenseNet) can be used by directly connecting each layer using input from the previous feature map. …
