A Gentle Introduction to Graph Neural Networks

Sep 02, 2021 A graph is the input, and each component (V,E,U) gets updated by a MLP to produce a new graph. Each function subscript indicates a separate function for a different graph attribute at the n-th layer of a GNN model. As is common with neural networks modules or layers, we can stack these GNN layers together.

Distillation - Definition Detailed Process Types Uses

Simple distillation involves heating the liquid mixture to the boiling point and immediately condensing the resulting vapors. This method is only effective for mixtures wherein the boiling points of the liquids are considerably different (a minimum difference of 25 o C).

Distillation Process - Chemistry Chart - SmartDraw

The liquid in the distillation flask is heated until it reaches its boiling point. The hot vapors above the boiling liquid rise through the distillation head and enter the condenser. When the vapor enters the condenser, whose walls are cooled by the jacket of cold water, it cools and condenses back to a liquid called the distillate or condensate.
