EmojiIntelligence - Neural Network built in Apple Playground using Swift

•    Swift

---

I used this challenge to learn more about neural networks and machine learning. A neural network consists of layers, and each layer has neurons. My network has three layers: an input layer, a hidden layer, and an output layer. The input to my network has 64 binary numbers. These inputs are connected to the neurons in the hidden layer. The hidden layer performs some computation and passes the result to the output layer neuron out. This also performs a computation and then outputs a 0 or a 1. The input layer doesn’t actually do anything, they are just placeholders for the input value. Only the neurons in the hidden layer and the output layer perform computations. The neurons from the input layer are connected to the neurons in the hidden layer. Likewise, both neurons from the hidden layer are connected to the output layer. These kinds of layers are called fully-connected because every neuron is connected to every neuron in the next layer. Each connection between two neurons has a weight, which is just a number. These weights form the brain of my network. For the activation function in my network, I use the sigmoid function. Sigmoid is a mathematical function. The sigmoid takes in some number x and converts it into a value between 0 and 1. That is ideal for my purposes, since I am dealing with binary numbers. This will turn a linear equation into something that is non-linear. This is important because without this, the network wouldn’t be able to learn any interesting things. I have already mentioned that the input to this network are 64 binary numbers. I resize the drawn image to 8x8 pixels which makes together 64 pixels. I go through the image and check each pixel if the pixel has a pink color I add a 1 to my array else I add a 0. At the end I will have 64 binary numbers which I can add to my input layer.

trigger - Trigger is a robust network automation toolkit written in Python that was designed for interfacing with network devices

•    Python

---

Trigger is a robust network automation toolkit written in Python that was designed for interfacing with network devices and managing network configuration and security policy. It increases the speed and efficiency of managing large-scale networks while reducing the risk of human error. Started by the AOL Network Security team in 2006, Trigger was originally designed for security policy management on firewalls, routers, and switches. It has since been expanded to be a full-featured network automation toolkit.

•    Python

---

Bitnodes is currently being developed to estimate the size of the Bitcoin network by finding all the reachable nodes in the network. The current methodology involves sending getaddr messages recursively to find all the reachable nodes in the network, starting from a set of seed nodes. Bitnodes uses Bitcoin protocol version 70001 (i.e. >= /Satoshi:0.8.x/), so nodes running an older protocol version will be skipped.See Provisioning Bitcoin Network Crawler for steps on setting up a machine to run Bitnodes. The Redis Data contains the list of keys and their associated values that are written by the scripts in this project. If you wish to access the data, e.g. network snapshots, collected using this project, see Bitnodes API v1.0.

brain - [UNMAINTAINED] Simple feed-forward neural network in JavaScript

•    Javascript

---

Download the latest brain.js. Training is computationally expensive, so you should try to train the network offline (or on a Worker) and use the toFunction() or toJSON() options to plug the pre-trained network in to your website. Use train() to train the network with an array of training data. The network has to be trained with all the data in bulk in one call to train(). The more training patterns, the longer it will probably take to train, but the better the network will be at classifiying new patterns.

retina-unet - Retina blood vessel segmentation with a convolutional neural network

•    Python

---

This repository contains the implementation of a convolutional neural network used to segment blood vessels in retina fundus images. This is a binary classification task: the neural network predicts if each pixel in the fundus image is either a vessel or not. The neural network structure is derived from the U-Net architecture, described in this paper. The performance of this neural network is tested on the DRIVE database, and it achieves the best score in terms of area under the ROC curve in comparison to the other methods published so far. Also on the STARE datasets, this method reports one of the best performances. The training of the neural network is performed on sub-images (patches) of the pre-processed full images. Each patch, of dimension 48x48, is obtained by randomly selecting its center inside the full image. Also the patches partially or completely outside the Field Of View (FOV) are selected, in this way the neural network learns how to discriminate the FOV border from blood vessels. A set of 190000 patches is obtained by randomly extracting 9500 patches in each of the 20 DRIVE training images. Although the patches overlap, i.e. different patches may contain same part of the original images, no further data augmentation is performed. The first 90% of the dataset is used for training (171000 patches), while the last 10% is used for validation (19000 patches).

DeepNeuralClassifier - Deep neural network using rectified linear units to classify hand written symbols from the MNIST dataset

•    Julia

---

Example scripts for a deep, feed-forward neural network have been written from scratch. No machine learning packages are used, providing an example of how to implement the underlying algorithms of an artificial neural network. The code is written in the Julia, a programming language with a syntax similar to Matlab. The neural network is trained on the MNIST dataset of handwritten digits. On the test dataset, the neural network correctly classifies 98.42 % of the handwritten digits. The results are pretty good for a fully connected neural network that does not contain a priori knowledge about the geometric invariances of the dataset like a Convolutional Neural Network would.

zarp - Network Attack Tool

•    Python

---

Zarp is a network attack tool centered around the exploitation of local networks. This does not include system exploitation, but rather abusing networking protocols and stacks to take over, infiltrate, and knock out. Sessions can be managed to quickly poison and sniff multiple systems at once, dumping sensitive information automatically or to the attacker directly. Various sniffers are included to automatically parse usernames and passwords from various protocols, as well as view HTTP traffic and more. DoS attacks are included to knock out various systems and applications. These tools open up the possibility for very complex attack scenarios on live networks quickly, cleanly, and quietly. The long-term goal of zarp is to become the master command center of a network; to provide a modular, well-defined framework that provides a powerful overview and in-depth analysis of an entire network. This will come to light with the future inclusion of a web application front-end, which acts as the television screen, whereas the CLI interface will be the remote. This will provide network topology reports, host relationships, and more. zarp aims to be your window into the potential exploitability of a network and its hosts, not an exploitation platform itself; it is the manipulation of relationships and trust felt within local intranets. Look for zeb, the web-app frontend to zarp, sometime in the future.
