(1)Which of the following do you typically see as you move to deeper layer in a ConvNet?[A] nHn_HnH and nWn_WnW decrease, while nCn_CnC increases.[B] nHn_HnH and nWn_WnW decrease, while nCn_CnC
(1)What is the “cache” used for in our implementation of forward propagation and backward propagation?[A]It is used to keep track of the hyperparameters that we are searching over, to speed up computa
(1) To help you practice strategies for machine learning, in this week we’ll present another scenario and ask how you would act. We think this “simulator” of working in a machine learning project will
(1) What does the analogy “AI is the new electricity” refer to?[A] AI runs on computers and is thus powered by electricity, but it is letting computers do things not possible before.[B]AI is powering
本篇讨论的内容是当你拿到一个边缘检测算子,比如说∣01−1013−3−113−3−101−10∣\left| \begin{matrix}0&1&-1&0\\1&3&-3&-1\\1&3&-3&-1\\0&1&-1&0\\\end{matrix} \right|∣∣∣∣∣∣∣∣01101331−1
(1)Problem StatementThis example is adapted from a real production application, but with details disguised to protect confidentiality.You are a famous researcher in the City of Peacetopia. The people
定理Suppose f(x)f(x)f(x) is continuous, positive and decreasing on [1,∞]\left[ 1,\infty \right][1,∞]. If an=f(n)a_n=f(n)an=f(n) for all n=1,2,...n=1,2,...n=1,2,..., then∑n=1∞an is convergent.
结论limx→0+xα(lnx)β=0,α,β>0\lim_{x \to 0^+} x^\alpha (lnx)^\beta =0 , \alpha ,\beta > 0x→0+limxα(lnx)β=0,α,β>0推导洛一次lnx的次数减少1,一直洛到次数<=0

在求极限的时候,我们有一大利器等价无穷小替换。但是在替换的时候如果使用不当,会产生精度不够的问题,从而导致我们的计算错误。那么为什么会产生精度不够的问题,等价无穷小的本质是什么,这就是本文要来探讨的问题。参考阅读:泰勒公式系列之一,多项式逼近大O表示同阶无穷小小o表示高阶无穷小如对于x2+2x3+x4x^2+2x^3+x^4x2+2x3+x4,用大O表示则表示为O(x2)O(x^2)O(x2),即
