Train-Test split and Cross-validation: Visual Illustrations & Examples
Creating an optimal model that strikes a balance between underfitting and overfitting requires careful consideration. To assess how well our model performs on new, unseen data, we employ the train-test split technique and cross-validation. Train-Test Split: To evaluate a model’s performance, we split the dataset into a training set (approximately
Asking the right questions
I very often see false choices about paths forward. One of the most common ones is the question about the future of humanity regarding AI, robotics, computers, cloning, vaccines, genetic engineering, you name it. Any new area of technology with a tremendous potential is always a multi-edged sword, and someone
Enhancing Accessibility and Inclusivity in Education with ChatGPT
Education is the cornerstone of progress, but for it to be truly impactful, it must be accessible and inclusive to all. In recent years, technology has played a pivotal role in transforming the educational landscape, making strides towards greater accessibility and inclusivity. Among these technological advancements stands ChatGPT, an AI-powered
Ethical Considerations in AI-Powered Education
Did you know that ethical considerations in AI-powered education are becoming increasingly crucial? Or that ensuring data privacy is a top concern in the integration of AI tools in classrooms? It is important for educators to stay on top of ethical considerations in AI-powered education so they can foster responsible
Understanding Confidence Intervals with an Intuitive Example
Confidence intervals (CIs) are a fundamental concept in data science. In this informative guide, we’ll delve into the world of confidence intervals using an intuitive example to help you grasp this concept with confidence. The Bus Stop Scenario: Imagine yourself at a bus stop where the expected arrival time of
Non-linear Relationships: When a 0 Pearson Correlation Coefficient Can Be Surprisingly Meaningful
The Pearson correlation coefficient (denoted as “r”) is widely used in statistics to measure the strength and direction of linear relationships between variables, ranging from -1 (perfect negative linear correlation) to +1 (perfect positive linear correlation). A Pearson correlation coefficient of 0 typically implies the absence of a linear relationship
The do nothing defense
Of course until you are successfully attacked, doing nothing about security is a great approach. It saves money and time and costs you nothing. So lots of folks do nothing, or almost nothing, and I include myself in this latter approach – almost nothing. As little as I can get
Firewalls are alive and well: here’s why
Many years ago, Gartner declared “Firewalls are Dead”, but some 20 years later (give or take) they are still reporting on “next-generation” firewalls. Why is that? Right to the answer Firewalls provide an economy of scale by substantially reducing the input sequences and noise that can contact interfaces. Let’s break
API Security vs AUI security
How is an application program interface different from an other application interface? At a basic level, they are the same – in the sense that anything that can be exploited from one can be exploited from another – or at least it should be that way from a security perspective.
The Threat Environment – 6 questions
People who don’t have to do it seem to not understand the nature of the cyber threat. This very short summary is intended for everyone who is responsible for it to hand to everyone else to help start a conversation and gain mutual understanding. The 6 questions people are commonly
