IP Networks - Q&A Part 2
Just some self-use notes for IP networks tutorials. Topic includes IP Routing, IPv6 and Mobile IP, TCP and Application Layer.
IP Networks - Multicast Routing (MOSPF, DVMRP, CBT, PIM)
In Multicasting, there is only one source and a group of destinations. The Source IP address is unicast, and the Destination IP address is Multicast. Multicast routers have another forwarding table, they make the decision according to the packet’s multicast destination address (M-DA).
Feature Selection and Dimensionality Reduction
In Machine Learning Problem, There must be Lots of different features have been proposed. Generally, we want to use less feature. Since More feature in model training = More memory usage by program = Potentially Longer model training time (higher computational complexity). More feature does not mean to produce better performance because it is possible to have irrelevant and unimportant features.
Feature Engineering in ML-based Phishing detection
Phishing uses e-mails or malicious websites to solicit personal information from an individual or company by posting as a trustworthy organization or entity. In this article we look at the features of phishing.
Quick Review on SVM, Neural Network, CNN and K-means clustering
This article provides a quick review into Machine Learning and Deep Learning techinques such as SVM, Artificial neural network, Convolutional Neural Network and K-means clustering. I made it for my own revision.
Build OpenCV with GPU support on Ubuntu 18.04
A quick guide to install OpenCV with GPU support. Prerequisites are Nvidia Driver, CUDA and cuDNN.
Digital Video Processing - Video Coding and Compression
Digital videos are represented as sequences of digital images, while analogue videos are represented as a sequence of continuous time varying signals. Images are taken from a camera or video camera in analogue form and subsequently digitized by certain electronic circuits into digital form.
Quick Review on K-NN, Decision tree and Naïve Bayes
This article provides a quick review into traditional Machine Learning techinques such as K-nearest neighbor, Decision tree, Random forest and Naïve Bayes. I made it for my own revision.
IP Networks - Unicast Routing (RIP, OSPF, BGP)
The Internet consists of Autonomous Systems (AS) interconnected with each other. Routing Protocols are used to facilitate the exchange of routing information between routers. The Intra-domain routing protocols includes Routing Information Protocol (RIP) and Open Shortest Path First (OSPF). The Inter-domain routing protocols includes BGP.
IP Networks - Address Matching (Trie and Binary Search)
Longest Prefix Match is a Search for the routing table entry that has the longest match with the prefix of the destination IP address. Search for a match on all 32 bits, then 31 bits, then 30, 29 ,28 ... until 0 bits. The Fast LPM ( Longest Prefix Match ) Alogirthms includes Trie, Binary search based on prefix length, and Binary search among all prefixes in forwarding table
