https://arxiv.org/abs/1906.04950 Pay Attention to Convolution Filters: Towards Fast and Accurate Fine-Grained Transfer Learning We propose an efficient transfer learning method for adapting ImageNet pre-trained Convolutional Neural Network (CNN) to fine-grained image classification task. Conventional transfer learning methods typically face the trade-off between training time and a arxiv.org 요약 ..

Deterministic Algorithms Probabilistic algorithms - Fermat Test > If n is a prime then $a^{n-1} \textrm{mod} n=1$ for all $1 If $a^{n-1} \textrm{mod} n \neq 1$ for some a, $1

Primes Asymmetric-key cryptography uses primes extensively. The topic of primes is a large part or any book on number theory. This section discusses only a few concepts and facts to pave the way for Chapter 10. Definition - A primeis divisible only by itself and 1. Q. What is smallest prime? A. The smallest prime is 2, which is divisible by 2 (itself) and 1. Cardinality of Primes Infinite Number..

Ordinary Differential Equations $y'(x) = f(x,y)$ Euler's Method > extremely simple approximation with low accuracy > Suppose tha twe know an initial state $y(x_0) = y_0$ > Approximate $y$ at $x = x_0 + h$, $h$ is a small step size $\frac{y(x_0+h) -y_0}{h} = f(x,y)$ => $y(x_0 +h) = y_0 + h f(x,y)$ - General formula > $x_{i+1} = x_i +h$ > $y_{i+1} = y_i + h f(x_i, y_i)$ Talyor Series - Approximati..

More tips to work with others Logging/ searching / debugging git grep - Allows to easily look for where a term exists in our working directory $ git grep -n README - git grep vs grep (linux) > Much faster and more convenient than grep > git grep is optimized for Git repositories --no-index : earch files in the current directory that is not managed by Git --untracked : search both tracked & untra..

Goals of segmentation - Group together similar-looking pixels for efficiency of further processing > simplify and / or change the representation of a image into something that is more meaningful and easier to analyze Major processes for segmenation - Separate image into coherent 'object' > Bottom-up : group tokens with similar features > Top-down : group tokens that likely belong to the same obj..

Parametric (global) warping - Transformation T is coordinate-changin machine : $p' = T(p)$ - What does it mean that $T$ is global? > is the same for any point $p$ > can be described by just a few numbers (parameters) - For linear transformations, we can represent T as a matrix $p' = Tp$ Common transformations - Translation - Rotation - Aspect - Affine - Perspective Scaling - Scaling a coordinate..

Network Layer Introduction Routing protocols ICMP Network-layer functions Recall : two network-layer functions - Forwarding : move packets from routers' input to appropriate router output -> data plane - Routing : determine route taken by packets from source to destination -> control plane Two approaches to structuring network control plane - per-router control (tranditional, still popular) - lo..

Github The single largest host for Git repositories - The central point of collaboration for millions of developers and projects Github and Git - Github is as remote repository of our project - By using Git commands, we can work for the project on our local computing machines Github workflow for a private project Gentralized workflow - one central hub can accept code and everyone synchronizes th..
