Let’s start directly with the maximum likelihood function: where phi is your conditional probability, i.e., sigmoid (logistic) function: and z is simply thenet input(a scalar): So, by maximizing the likelihood we maximize the probability. Since we are talking about “cost”, lets reverse ...
My next tutorial goes over How to Use and Create a Z Table (Standard Normal Table). If you have any questions or thoughts on the tutorial, feel free to reach out through YouTube or X.Frequently Asked Questions What does a boxplot show?
But if the same languages are fed to a machine, will it be able to comprehend them? So, this where Natural Language Processing plays a key role. Natural Language Processing is the ability of a computer program to understand human language as it is spoken. In other words, Natural Language ...
2020). For example, the short-term processes might look different than the long-term processes. Based on conservation of resources theory (COR theory, Hobfoll,1989), individuals need to invest resources to keep existing or gain
In its simplest form, it is a fact or piece of data from a study of a large quantity of numerical data. For example, the statement “the statistics show that the crime rate has increased” is referring to facts or numbers collected from research involving crime rates. More precisely, a ...

Fun fact:While the bell curve is normally associated with grades (i.e. 5% of the class will get an A and 10% of the class will get a B), it’s also quite normal to have a bimodal distribution where roughly half of a class will do very well (getting As and Bs) and the other ...
What type of statistical test would be used for the following research question? Married couples have a significant increase risk for divorce with the birth of very low birth weight infants compared to normal newborn infants. Describe and give examples of research questions for which external va...
How does Q-learning work? The Q-learning technique acts as a crib sheet for the reinforcement learning agent. It enables the RL agent to use the feedback of the environment to learn the best actions it can take in different circumstances. ...
R-squared measures the goodness of fit but does not provide insights into prediction accuracy. Adjusted R-squared: It adjusts the R-squared value by the number of predictors in the model, accounting for model complexity. It penalizes overfitting and provides a more reliable measure of the model...
