By IRB Media

Get the Summary of Brian Christian's The Alignment Problem in 20 minutes. Please note: This is a summary & not the original book. Original book introduction: In best-selling author Brian Christian’s riveting account, we meet the alignment problem’s “first-responders,” and learn their ambitious plan to solve it before our hands are completely off the wheel. In a masterful blend of history and on-the ground reporting, Christian traces the explosive growth in the field of machine learning and surveys its current, sprawling frontier. Readers encounter a discipline finding its legs amid exhilarating and sometimes terrifying progress. Whether they—and we—succeed or fail in solving the alignment problem will be a defining human story.

#1

The perceptron is a simple model used to demonstrate the power of artificial neural networks. It consists of a single artificial neuron with four hundred inputs and weights that are adjusted using an optimization algorithm.

#2

The basic idea of the perceptron is to have a machine learn from examples. It is a simple, yet effective, method that has been used by machines to learn how to do tasks that require human intelligence, such as speech recognition and translation.

#3

Neural networks had great potential, but they had their limitations. For example, they could not recognize cards with an odd or an even number of squares. They needed to be modified to work properly.

#4

In 2005, Amazon launched Mechanical Turk, an application that allowed human labor to be recruited on a large scale. It was used for tasks such as image captioning and image classification, which became the new grand challenge for computer vision.

#5

During the 2000s, computers became fast enough to run neural networks on, and GPUs were developed for gaming that could process huge amounts of data in real time. Krizhevsky, a student of Hinton, built a network that learned to recognize cats in under two weeks using ImageNet, a benchmark dataset of 1. 2 million images.

#6

In 1959, a researcher named Frank Rosenblatt created a computer model that could recognize images, and named it the perceptron. The perceptron was not very accurate, but it was a stepping stone towards the invention of neural networks, which are now used in image recognition systems.

#7

In 2015, Google Photos had a racist image-classification system that labeled photos of black people as gorillas. It took Google two years to fix the problem.

#8

The history of photography has demonstrated the power of a single image to transcend racial stereotypes and convey human dignity.

#9

In the 1960s and ’70s, Kodak executives realized that their film was actually pretty bad at capturing darker skin tones, so they began including models of different races in their advertisements.
