1. Functional Regression Let the covariate be an at least twice continuously differentiable random function defined wlog. on an interval and the corresponding the response. For simplicity we assume centered …
1.) Functional Principal Component Analysis Let be a centered smooth random function in , with finite second moment . Without loss of generality we assume instead of some arbitrary compact …
1. Generalize the Procedure The very simple Educated Guess Procedure is not only very simple, the procedure is also very unrealistic. At most the assumption that are independent and identically …
1. Perform the Analyze To start with, we load the “rockyou.txt.tar.gz” password list using wget. I’m not sure if it is legal to provide a link for the list, therefore …
1. Test the Enviroment 1.1 Simulation of a Brownian Motion The purpose of the first notebook entry is to check if matplotlib is correctly installed. We simulate 20 Brownian Motions …
1. Requirements 2. Install Software In this section we will install some stuff which will make life easier. In constrast to Spark or Hadoop it is only required to install …
1. Requirements We need an SD Card with Lubuntu, Hadoop and Spark installed. 2. Build the Cluster 2.1 Clone the SD Card sudo shutdown 0 of your orangepi and remove …
1. Requirements An Orangepi with Lubuntu running, see this post for further instructions. 2.Install the Components 2.1 Update Java In fact Hadoop is not necessary for Spark. However, we will …

1. Introduction This Project is about making an educated guess to derive an unknown password based on hacked password lists (Google: “RockYou”). In this section we will introduce the mathematical …
1. The Fourier Transform The Fourier transform of an integrable function with is given by (1) Under suitable conditions, the inverse transform from to with is then given by …
1. Kernel Functions In general, a kernel is an integrable function satisfying is symmetric (e.g. if ) . Popular univariate () kernel functions: Uniform: Epanechnikov: Gaussian: An easy way …
1. Theoretical Background I want to start with some theory which will in the end lead us to the Matlab coding. If you are not interested how to derive the …
