Machine Learning: Using Occam’s Razor to Generalize

A simple thought experiment shows us how

This approach is contrary to Fisher's method where we formulate all theories before encountering the data. We came up with the model after we saw the cards we drew.

Boeing’s Sidelined Fuselage Robots: What Went Wrong?

It’s not what we learn, it’s what we forget

By all means, let’s build machines that enhance our abilities. But let’s not forget that the really amazing thing is not the tool, but the tool builder.

Boeing Workers, Please Don’t Kick the Robot on Its Way Out

The jetliner manufacturer’s decision to give the robots’ job back to machinists underlines the hard realities of automation. For example, it doesn’t always work

Robot error turned out to be a bigger problem than human error.

The Greatest Threat We Face From AI—and What We Can Do

Here’s a list of things that have really happened with artificial intelligence (AI), in order of increasing severity.

When we get to the end of the list, we will see that it is like beads connected by a string—revealing the most dangerous threat.

How Algorithms Can Seem Racist

Machines don’t think. They work with piles of “data” from many sources. What could go wrong? Good thing someone asked…

Some of the recent conflicts around algorithms and ethnicity are flubs that social media entrepreneurs will regret. Others may endanger life.

Occam’s Razor Can Shave Away Data Snooping

The greater an object's information content, the lower its probability.

One technique to avoid data snooping is based on the intersection of information theory and probability: An object’s probability is related to its information content. The greater an object’s information content, the lower its probability. We measure a model’s information content as the logarithmic difference between the probability that the data occurred by chance and the number of bits required to store the model. The negative exponential of the difference is the model’s probability of occurring by chance. If the data cannot be compressed, then these two values are equal. Then the model has zero information and we cannot know if the data was generated by chance or not. For a dataset that is incompressible and uninformative, swirl some tea…

Big Tech Tries to Fight Racist and Sexist Data

The trouble is, no machine can be better than its underlying training data. That’s baked in

The problem with machine learning-based AI in police work is not so much its inherent bias (none of us is bias-free) but the delegation to a machine of what should be a human decision.

Machine Learning, Part 2: Supervised Learning

Machine learning isn’t hard to understand; it’s just different. Let’s start with the most common type

The neat thing about machine learning is that the algorithm can extract general principles from the dataset that can then be applied to new problems. It is like the story that Newton observed an apple fall and then derived from it the general law of gravity that applies to the entire universe.

Is Ray Kurzweil’s Singularity Now Nearer — or Impossible?

In response to Kurzweil’s talk at the COSM Technology Summit, panelists noted that AI achievements are revolutionary in size but limited by their nature in scope

George Montañez, Assistant Professor of Computer Science at Harvey Mudd College, took issue with Kurzweil’s claim that AlphaGoZero needed no instructions to beat humans at the game of Go: “For a system like this to work, a human must define the incentive structure, also encoding the assumptions.” The sheer power of a computing system does not cause it to do anything at all.

Former Microsoft Head of Research: Machines Will Soon Know Better Than Your Doctor

Other experts at the COSM Technology Summit were skeptical of Craig Mundie’s claims

Mundie, former Microsoft Chief Research & Strategy Officer, formerly told his audience that Big Data will enable each person to be “completely understood” by machines that can produce a computer facsimile of each detail. It would be far too complex for human physicians to make sense of, he said.

The Challenge of Teaching Machines to Generalize

Teaching students simply to pass tests provides a good illustration of the problems

We want the machine learning algorithms to learn general principles from the data, and not merely little tricks and trivia that that score high but ignore problems.

Machines Are Not Really Learning

A bit of machine learning history helps us see why

You can build your own chatbot

New tools have made it comparatively easy

Natural Language Interfaces (the technical term for a chatbot) are becoming more and more popular. Many dial-in phone services have switched from numeric interfaces (“Dial 1 for sales, 2 for service, etc.”) to natural language interfaces (“Please say what you are calling about”). Where they have taken off though is with chatbots. Many online help systems at least start with chatbots, which collect basic information about a problem or situation and point to existing solutions before passing the contact off to a human expert. Additionally, the rise of the Generation Text, as well as the proliferation of chat-based groupware such as Slack, means that text-based natural language interfaces are one of the best ways of interacting with young people. Is…

Lazy Engineers Treat AI as Magic!

When software engineers mostly use shared code, they save time but risk losing understanding

Building from scratch is different. Knowing when to use a tool and why and knowing the limitations of each tool separates the craftsperson from the novice.
