Google’s Chatbot: Almost Perfect 🤖

TL;DR

AI algorithms are now able to create IQ tests and chatbots that exhibit human-like conversational skills, with the potential to revolutionize various industries.

Transcript

Dear Fellow Scholars, this is Two Minute Papers with Dr. Károly Zsolnai-Fehér. When I was growing up, IQ tests were created by humans to test the intelligence of other humans. If someone told me just 10 years ago that algorithms will create IQ tests to be taken by other algorithms, I wouldn’t have believed a word of it. Yet, just a year ago, scient... Read More

Questions & Answers

Q: How well did DeepMind's program perform on abstract reasoning IQ tests?

The program achieved a 62% accuracy rate when faced with distractor objects, and a 78% accuracy rate when the distractors were removed.

Q: What is GPT-2 and what is its training data?

GPT-2 is a neural network variant trained on 1.5 billion parameters. It learned our language by reading and analyzing vast amounts of internet data.

Q: How did Meena, the Google Brain chatbot, perform in conversing with humans?

Meena demonstrated remarkable human-like conversational abilities, answering questions sensibly, coherently, and even cracking jokes.

Q: How is the Sensibleness and Specificity Average (SSA) score used to measure human-likeness in chatbots?

The SSA score correlates strongly with human-likeness, allowing it to be used as a proxy for measuring how closely a chatbot resembles a real human.

Summary & Key Takeaways

• DeepMind created a program that generates IQ tests inspired by human tests and uses a neural network to solve them with up to 78% accuracy.

• OpenAI's GPT-2, trained on 1.5 billion parameters, can complete sentences and simulate conversations in a scholarly manner.

• Google Brain released Meena, an open-domain chatbot with 2.6 billion parameters, capable of engaging in human-like conversations and achieving high scores on the Sensibleness and Specificity Average (SSA) test.
