🧵1/10: Systematic vs. Random Error 🎯

Welcome to this thread where we'll explore the differences between systematic and random error, two types of error that can impact the accuracy and precision of your data. Let's dive in! #Statistics #DataScience Image
🧵2/10: Error in Measurements 📏

In any measurement process, there's a possibility of errors occurring. Understanding the types of errors that can arise helps us to design experiments that minimize their impact and improve the quality of our results. #DataScience
🧵3/10: Systematic Error 📐

Systematic errors, or biases, are consistent and reproducible inaccuracies that occur in the same direction every time. These errors can be due to faulty equipment, incorrect calibration, or even observer bias. #DataScience

1/10: 🧪📊 Introducing Generalized Linear Models (GLMs) and how to perform them using R! A thread. #GLM #Rstats #DataScience Source: https://towardsdata...
2/10: 💡GLMs are a general class of regression models that extend linear regression, allowing for a variety of response distributions & link functions. They're used for modeling relationships between a response variable & one or more explanatory variables. #RStats #DataScience
3/10: 📐The main components of a GLM are:

Random Component: The response variable's distribution (e.g., Gaussian, Poisson, Binomial)
Systematic Component: Linear predictor (linear combo of explanatory variables)
Link Function: Connects the two components. #Rstats #DataScience

🧵1/10 Multivariate Normality: A Guide to Controlling It Using the MVN Package in R 📊
Multivariate normality is a key assumption in many statistical techniques. Let’s explore how to test and control for MVN using the MVN package in R. #rstats #DataScience
cran.r-project.org/web/packages/M…
🧵2/10 Installing the MVN Package 📦
First, let's install and load the MVN package in R:

install.packages("MVN")
library(MVN)

This package offers a range of functions to assess and visualize multivariate normality. #rstats #DataScience
🧵3/10 Testing for MVN 🔎
To test your dataset for MVN, use the mvn() function. The function takes a data frame or a matrix as input and returns a list of tests, including Mardia's, Henze-Zirkler's, and Royston's tests.

🧵1/9 A deep dive into the history of #Backpropagation: A key technique in training multilayer architectures for neural networks. This powerful method revolutionized the way we train AI systems, leading to major breakthroughs in various domains. 🤖#DataScience #DeepLearning #AI Source: https://www.youtube...
🧵2/9 #Backpropagation is based on a simple concept: use gradient descent to optimize multilayer networks. By applying the chain rule for derivatives, it computes gradients efficiently, leading to optimized weight configurations in each layer of the network. #DataScience #AI
🧵3/9 The shift to Rectified Linear Units (ReLU) accelerated learning in deep networks, allowing training without unsupervised pre-training. This non-linear activation function proved more effective than its smoother predecessors like tanh(z) or 1/(1+exp(−z)). #ReLU #DataScience
