Question-13. Which of the following is not the Classification algorithm?

ALogistic Regression

BSupport Vector Machine

CNeural Network

DHidden Markov Models

ENone of the above
Logistic regression
Logistic regression is a model used for prediction of the probability of occurrence of an event. It makes use of several predictor variables that may be either numerical or categories.
Support Vector Machines
As with naive Bayes, Support Vector Machines (or SVMs) can be used to solve the task of assigning objects to classes. But the way this task is solved is completely different to the setting in naive Bayes.
Neural Network
Neural Networks are a means for classifying multidimensional objects.
Hidden Markov Models
Hidden Markov Models are used in multiple areas of machine learning, such as speech recognition, handwritten letter recognition, or natural language processing.

I practiced a question similar to this, and I think the answer might be Hidden Markov Models since they’re used for different tasks like time series analysis.

I think Support Vector Machines and Neural Networks are definitely classification algorithms, but Hidden Markov Models seem more like a sequence model to me.

I remember that logistic regression is often used for binary classification, but I’m not sure if it’s considered a classification algorithm in all contexts.

This is a tricky one. I know the basics of these algorithms, but I'm not 100% sure which one is not a classification algorithm. I think I'll eliminate the options I'm most confident about, and then make an educated guess on the remaining one.

Okay, let me break this down. Logistic regression, SVM, and neural networks are all well-known classification algorithms, so those can't be the answer. Hidden Markov Models are used for things like speech recognition, so that's probably not a classification algorithm either. I'm going to go with E, "None of the above."

Hmm, I'm a bit confused here. I know logistic regression, SVM, and neural networks are all classification algorithms, but I'm not sure about Hidden Markov Models. I'll have to think this one through carefully.

I'm pretty confident that the answer is E. None of the above, since the question is asking for the algorithm that is not a classification algorithm, and all the options provided are classification algorithms.

D) Hidden Markov Models? Really? That's more of a sequence modeling technique, not a Classification algorithm. This question is a bit of a head-scratcher.
