Question

Which of the following statements with regard to Large Language Models (LLMs) used in machine learning is/are correct?

1LLMs assign probabilities to the next possible words and then pick the one with the highest probability.
2LLMs process data through mathematical optimization to minimise prediction errors.
3LLMs produce unbiased outputs.

Select the answer using the code given below :

Options

a

1 only

b

1 and 2 only

Answer
c

1, 2 and 3

d

2 and 3 only

Explanation

Statements 1 and 2 are correct. LLMs operate as advanced probabilistic systems that analyze text patterns to compute statistical distributions, predicting the most probable next word in a sequence based on prior context. Their underlying training architecture uses mathematical loss functions and optimization algorithms to reduce prediction errors across datasets. Statement 3 is incorrect because LLMs frequently duplicate or amplify systemic biases present in their training data, meaning they do not produce completely objective or unbiased outputs.
