Given inputs x and y, the output z = x + y.The upstream gradient is ∂L/∂z where L is the final loss.The local gradient is ∂z/∂x, but since z = x + y, ∂z/∂x = 1.Now, the downstream gradient ∂L/∂x is the product of the upstream gradient and the local gradient, but since the local gradient is unity, the downstream gradient is … Web在圖論中，網絡流（英語： Network flow ）是指在一個每條邊都有容量（Capacity）的有向圖分配流，使一條邊的流量不會超過它的容量。 通常在运筹学中，有向图称为网络。 顶点称为节点（Node）而边称为弧（Arc）。一道流必須符合一個結點的進出的流量相同的限制，除非這是一個源點（Source）──有 ...
WebMay 22, 2024 · Churn flow, also referred to as froth flow is a highly disturbed flow of two-phase fluid flow. Increasing velocity of a slug flow causes that the structure of the flow becomes unstable. The churn flow is characterized by the presence of a very thick and unstable liquid film, with the liquid often oscillating up and down. WebMar 16, 2024 · Depending on network architecture and loss function the flow can behave differently. One popular kind of undesirable gradient flow is the vanishing gradient. It refers to the gradient norm being very small, i.e. the parameter updates are very small which slows down/prevents proper training. It often occurs when training very deep neural …
WebMay 26, 2024 · In this note, my aim is to illustrate some of the main ideas of the abstract theory of Wasserstein gradient flows and highlight the connection first to chemistry via the Fokker-Planck equations, and then to machine learning, in the context of training neural networks. Let’s begin with an intuitive picture of a gradient flow.
