https://simple.wikipedia.org/wiki/Spreadsheet
A Spreadsheet is a computer program that imitates a paper worksheet. It shows a large sheet (like a sheet of paper) that has many cells in a grid of rows and columns. Users can put words or numbers into the cells, to make headings and store information (usually numbers). You can also move the grid lines around so that some cells are bigger than others, and change the color or size of text/font, the same way font/text is changed in a word processor. You can even put pictures in the worksheets, make multiple pages, and print out their results on real paper.

经典教材:爱上统计学Statistics for People Who (think They) Hate Statistics

The gentle good humor of that answer imbues one of his enduring efforts for SAGE Publishing, the Statistics for People Who (Think They) Hate Statistics books.
“Neil Salkind’s statistics textbooks were so successful because Neil had a unique gift for communicating an often-intimidating subject in a playful and humorous way,” recalled Helen Salmon, a senior acquisitions editor with SAGE. “His bestselling Statistics for People Who (Think They) Hate Statistics put students at ease, without being condescending. Neil was incredibly generous with his time and expertise: he published his email address in the front of his books, and would respond to several emails a day from students from around the world who asked for his advice and help. He was a wonderful author to work with, as he was always dreaming up the next project.”

Forty Studies That Changed Psychology: Explorations Into the History of Psychological Research is an academic textbook written by Roger R. Hock that is currently in its eighth edition. The book provides summaries, critiques, and updates on important research that has impacted the field of psychology. The textbook is used in psychology courses at all levels of education and has been translated into six languages. It is used to properly relate the present knowledge of psychology with the original research that led to it. It is a window into the history of psychology for anyone wishing to expand their understanding of the true roots of psychology

From Wikipedia, the free encyclopedia
Generative Pre-trained Transformer 3 (GPT-3) is an autoregressive language model that uses deep learning to produce human-like text.
It is the third-generation language prediction model in the GPT-n series (and the successor to GPT-2) created by OpenAI, a San Francisco-based artificial intelligence research laboratory.[2] GPT-3's full version has a capacity of 175 billion machine learning parameters. GPT-3, which was introduced in May 2020, and was in beta testing as of July 2020,[3] is part of a trend in natural language processing (NLP) systems of pre-trained language representations.
This is a real example, see https://www.ambrogiorobot.com/en. Disclosure: LF owns one.
See https://en.wikipedia.org/wiki/ELIZA. A classic book still worth reading on the ELIZA effect and AI in general is (Weizenbaum 1976). In 2014 some people claimed, mistakenly, that a chatbot had passed the test. Its name is “Eugene Goostman”, and you can check it by yourself, by playing with it here: http://eugenegoostman.elasticbeanstalk.com/. When it was tested, I was one of the judges, and what I noticed was that it was some humans who failed to pass the test, asking the sort of questions that I have called here “irreversible”, such as (real examples, these were asked by a BBC journalist) “do you believe in God?” and “do you like ice-cream”. Even a simple machine tossing coins would “pass” that kind of test.
See for example the Winograd Schema Challenge (Levesque et al. 2012).
For an excellent, technical and critical analysis, see McAteer (https://matthewmcateer.me/blog/messing-with-gpt-3/ ." data-track="click" data-track-action="reference anchor" data-track-label="link" data-test="citation-ref" aria-label="Reference 2020">2020). About the “completely unrealistic expectations about what large-scale language models such as GPT-3 can do” see Yann LeCun (Vice President, Chief AI Scientist at Facebook App) here: https://www.facebook.com/yann.lecun/posts/10157253205637143.
The following note was written by the journalists, not the software: “[…] GPT-3 produced eight different outputs, or essays. Each was unique, interesting and advanced a different argument. The Guardian could have just run one of the essays in its entirety. However, we chose instead to pick the best parts of each, in order to capture the different styles and registers of the AI. Editing GPT-3’s op-ed was no different to editing a human op-ed. We cut lines and paragraphs, and rearranged the order of them in some places. Overall, it took less time to edit than many human op-eds.” (GPT-3 2020).
For some philosophical examples concerning GPT-3, see http://dailynous.com/2020/07/30/philosophers-gpt-3/.
For a more extended, and sometimes quite entertaining, analysis see (Lacker https://lacker.io/ai/2020/07/06/giving-gpt-3-a-turing-test.html ." data-track="click" data-track-action="reference anchor" data-track-label="link" data-test="citation-ref" aria-label="Reference 2020">2020).
For an interesting analysis see (Elkins and Chun 2020).
