Exponential decay is the decrease in a quantity N according to the law N ( t ) = N 0 e − λ t , ( 1 ) N(t)=N_{0}e^{-\lambda t} , (1) N(t)=N0e−λt,(1) for a parameter t and constant lambda (known as th
EMA介绍 EMA,指数移动平均,常用于更新模型参数、梯度等。 EMA的优点是能提升模型的鲁棒性(融合了之前的模型权重信息) 代码示例 下面以yolov7/utils/torch_utils.py代码为例: class ModelEMA:""" Model Exponential Moving Average from https://github.com/rwightman/pytor
Example 4:The exponential map of SO(3) We have seen in Ex.3 that R ˙ = R [ ω ] × ∈ T R S O ( 3 ) . \dot R = R [ω]_× ∈ T_RSO(3). R˙=R[ω]×∈TRSO(3). For ω constant, this is an ordinary differential e
