Stand-alone R installation on USB stick from Windows

Avoiding installing applications on any PC we need to work on every time can be an efficient solution. In fact, for some of them it is possible to install an application on a USB stick and carry everything you need to work with you. In this article we will install the R console on a USB stick. In this way we will be able to work with R, do our statistical analysis on any PC with Windows. Once finished, we will remove the key, leaving the PC clean.

Let’s build a Single Layer Perceptron (SLP) with Python

This article aims to explore the world of perceptrons, focusing in particular on the Single Layer Perceptron (SLP), which, although it constitutes only a small fraction of the overall architecture of deep neural networks, provides a solid basis for understanding the fundamental mechanisms of Deep Learning. We will also introduce practical implementation examples in Python, illustrating how to build and visualize an SLP using libraries such as NumPy, NetworkX and Matplotlib.

Initial Raspbian Setup on Raspberry Pi 4: A Step-by-Step Guide

The initial Raspbian setup is the crucial first step to start using your Raspberry Pi 4. In this guide, we’ll explore the initial setup process in detail, covering key elements such as language, keyboard, and password. Following these steps will allow you to prepare your board for a variety of projects and uses.

From Uncertainty to Knowledge: Foundations of Bayesian Statistics

Bayesian statistics is an approach to statistics that relies on Bayes’ theorem to update the probabilities of hypotheses in light of new available data. Unlike the Frequentist approach, Bayesian statistics treats probabilities as expressions of knowledge or uncertainty rather than as frequencies of events.

Brute Force vs Greedy: two approaches compared

Algorithmic problem solving is a fundamental element in computer science, requiring the application of efficient strategies to obtain optimal or acceptable solutions in terms of time and space. Two distinct approaches in this context are known as Brute Force and Greedy. These represent two ends of the algorithmic complexity spectrum, each with its own advantages and limitations.

The Fibonacci Series: three different algorithms compared

The efficiency of algorithms plays a central role in software development, directly influencing the performance and responsiveness of applications. In this context, the Fibonacci series provides fertile ground for exploring and comparing different implementation strategies, from the classic recursive approach to more optimized solutions such as iteration and dynamic programming.

Kruskal algorithm and graphs: the calculation of the Minimum Spanning Tree and the Greedy approach

The Kruskal algorithm is a greedy algorithm used to find a Minimum Spanning Tree (MST) in a graph with weights on the edges. A Minimum Spanning Tree (MST) of a graph is a subset of the edges that connects all the nodes of the graph such that the sum of the weights of the edges is minimal.

The Backtracking technique vs Brute Force

In the vast landscape of problem-solving algorithms, two main approaches emerge as distinct but complementary methods: Backtracking and Brute Force. Both are used to solve computational problems by exhaustively searching for solutions, but their strategies differ significantly.

Recursive Algorithms

A recursive algorithm is an algorithm that solves a problem by dividing it into smaller sub-problems of the same nature. The solution of the overall problem is obtained by combining the solutions of the sub-problems. The recursive approach is based on recursive calling, which consists of invoking the same function (or procedure) within the very definition of that function.

Sequential and Binary Search: Complete Guide to Data Search Efficiency

In the vast world of computing, the ability to identify and retrieve information is one of the fundamental skills. Data search, in particular, is a crucial aspect that directly affects the performance and efficiency of algorithms. Among the most common and widely used search algorithms, “Sequential Search” and “Binary Search” stand out.
