Perplexity refers to how predictable a piece of text is to a language model. Burstiness refers to how repetitive or overemphasized certain words or phrases appear in a piece of text. The lower the perplexity, the more predictable the text, and the higher chance it was generated by an AI lan...
To summarize, the paper has made the following contributions. First, to the best of our knowledge, this is the first attempt to use a growth strategy to train an LLM with 100B+ parameters from scratch. Simultaneously, it is probably the lowest-cost model with 100B+ parameters, costing only...
s accuracy is improved by compressing and decompressing text. This also allows it to calculate the conditional probability of each word. GPT models can perform well in “few shots” settings and respond to text samples that have been seen before. They only require a few examples to produce ...
learn simultaneously the word feature vectors and the parameters of that probability function. In the following two papers, it is shown that both to project all words of the context onto a continuous space and calculate the language model probability for the given context can be performed by a ...
These chatbots are based on alarge language model, or LLM, a type of AI neural network that uses deep learning (it tries to simulate the human brain) to work with an enormous set of data to perform a variety ofnatural language processingtasks. ...
text is. Usually, the perplexity score of an AI-written text is low compared to a human-written text (as humans are far more unpredictable than computers are). In simple terms, if a word or phrase is used in a piece of writing written in AI, it’s far more likely to appear later....
I calculate the uncertainty in predicting each word appearance in every text through perplexity (Griffiths & Steyvers,2004), a measure that has been used for language identification (Gamallo et al.,2016), to discern between formal and informal tweets (Gonzàlez,2015), to model children’s early...
like calculate what a parabola is, how fast a car is going to go, or how much money a business is going to make. Those are just mathematical calculations. Typical kinds of programs that do that are financial modeling software for simple math equations, etc. That’s the...
Generative AI can produce outputs in the same medium in which it is prompted (e.g., text-to-text) or in a different medium from the given prompt (e.g., text-to-image or image-to-video). Popular examples of generative AI include ChatGPT, Gemini, DALL-E, Midjourney, and Perplexity,...
