Winning Tag Lines Are Hard Enough To Write…

But AI really flops at that

AI tools help us do things better, faster, or more efficiently. But they lack the mind needed to know when “I’m loving’ it” is the winning slogan—and stop there.

The Real Future of Self-Driving Cars Is — Better Human Drivers!

Manufacturers are improving safety by incorporating warning systems developed for self-driving cars into conventional models

This human-plus-machine combination is proving more potent than the machine-only hype/promise.

Successful Generalization Is a Key to Learning

In machine learning, the Solomonoff induction helps us decide how successful a generalization is

In the model of generalization set out in the paper, imperfect models can get better scores but they are discounted according to the amount of error they have.

Machine Learning Dates Back To at Least 300 BC

The key to machine learning is not machines but mathematics

Machine learning is not a new technique, but is simply a modern extension of a tool that we have had in our toolbox since the days of the Babylonians. It continues to serve us well to help us extrapolate our data to estimate the value of unknown results and to help find the signal in noisy data.

AI as the Artful Dodger

Watch what happens when I train a neural network on portraits of 56 famous scientists, starting the process with a right eye
New AI is much more sophisticated but the old and new AI share the property that the final result is nothing more than an interpolation of the training images used to train the AI. Read More ›

A Closer Look at Detroit: Become Human, Part III

The second pillar of the AI religion is reductionism, the reduction of humanity to matter and energy

If the qualities that define being human (so that there is an obvious distinction between what is human and what is not) are not material by nature; then the premise of a compelling story about androids that become and surpass human beings as intelligent life falls flat.

Why we can’t just ban killer robots

Should we develop them for military use? The answer isn’t pretty. It is yes.

Autonomous AI weapons are potentially within the reach of terrorists, madmen, and hostile regimes like Iran and North Korea. As with nuclear warheads, we need autonomous AI to counteract possible enemy deployment while avoiding its use ourselves.

Can We Program Morality into a Self-Driving Car?

A software engineering professor tells us why that’s not a realistic goal

Any discussion of the morality of the self-driving car should touch on the fact that the industry as a whole thrives on hype that skirts honesty.

WROCLAW, POLAND - JANUARY 28, 2020: Physical version of Bitcoin (BTC), Trezor (cryptocurrency hardware wallet) and other cryptocurrencies background.

Bitcoin: Is Lack of Trust the Biggest Security Threat?

It’s almost a parable: Everyone can see, no one can access, the millions trapped in the ether by a password known only to a dead man

Is this the future of currency? Seems like the Dark Ages to me. Bitcoin is a clever idea, but it is perhaps too clever for its own good.

That Robot Is Not Self-Aware

The way the media cover AI, you'd almost think they had invented being hopelessly naïve
If this is how The Telegraph reports on a robotic arm, can you imagine what it will sound like when we get humanoid robots who seem to carry on conversations? We had best inoculate ourselves now against AI hype from science reporters while most of us still have enough self-awareness to realize what’s going on. Read More ›

Part 2: Navigating the Machine Learning Landscape — Supervised Classifiers

Supervised classifiers can sort items like posts to a discussion group or medical images, using one of many algorithms developed for the purpose
In Part 1 of our series, we looked at machine learning, including supervised learning, unsupervised learning, and reinforcement learning. Now we’re going to dive a little deeper into how supervised learning works. Read More ›

The Numbers Don’t Speak for Themselves

The patterns uncovered by machine learning may reflect a larger reality or just a bias in gathering data

Because Machine Learning is opaque—even experts cannot clearly explain how a system arrived at a conclusion—we treat it as magic. Therefore, we should mistrust the systems until proven innocent (and correct).

Artificial Intelligence Is Actually Superficial Intelligence

The confusing ways the word “intelligence” is used belie the differences between human intelligence and machine sophistication

Words often have more meaning than we hear at first. Consider colors. We associate green with verdant, healthy life and red with prohibition and danger. But these inferences are not embedded in the basic meaning of “red” or “green.” They are cultural accretions we attach to words that enable the richness of language. That, by the way, is one reason why legal documents and technical papers are so difficult to read. The terms used are stripped clean of such baggage, requiring additional words to fill the gaps. The word “intelligent” is like that. Saying that a computer, or a program, is intelligent can lead us down a rabbit hole of extra meaning. An honest researcher merely means the computer has Read More ›

Part 1: Navigating the Machine Learning Landscape

To choose the right type of machine learning model for your project, you need to answer a few specific questions
Most machine learning systems fall into three main categories—supervised learning, unsupervised learning, and reinforcement learning. The choice of system depends first on which category of machine learning best addresses your situation. Read More ›

Does AI Art Spell the End of the Artist’s Way of Life?

An AI-produced painting sold at auction for $432,500. But is it a trend or just a novelty?

Rather than announce that human artists are now doomed, software engineer Ben Dixon interviewed a number of them and came away with a rather different picture, that “AI-generated art will improve, but artistic creativity will remain a human discipline.”

Is an Amoeba Smarter Than Your Computer?

Hype aside, the microbe’s math skills ace the Traveling Salesman problem and may help with cybersecurity
When we hear hype about machines that will soon out-think people, we might put it in perspective by recalling that we still struggle to build a machine that can out-think amoebas looking for crumbs. Read More ›

It’s 2019: Begin the AI Hype Cycle Again!

Media seemingly can’t help portraying today’s high-tech world as a remake of I, Robot (2004), starring you and me.
I have a problem with the possible outcomes when people who don’t know the difference between technology fact and fiction make important decisions based on information from journalists who write as if every computer is a potential personality like HAL from Space Odyssey 2001. Read More ›

Researchers: Deep Learning Vision Is Very Different from Human Vision

Mistaking a teapot shape for a golf ball, due to surface features, is one striking example from a recent open-access paper
The networks did “a poor job of identifying such items as a butterfly, an airplane and a banana,” according to the researchers. The explanation they propose is that “Humans see the entire object, while the artificial intelligence networks identify fragments of the object.” Read More ›

2: AI Can Write Novels and Screenplays Better than the Pros!

AI help, not hype: Software can automatically generate word sequences based on material fed in from existing scripts. But with what result?

“AI rites reel gud!” Seriously, the idea is not new. Back in the 1940s, George Orwell (1903–1950) thought that a machine could write popular novels so long as no creative thinking was involved. Thus, in his 1984 police state world, one of the central characters has a job minding a machine that mass produces them. In the 1960s, some film experiments were done along these lines, using Westerns (cowboy stories). At the time, there were masses of formula-based film material to work with in this popular genre. But what does the product look and sound like? In 2016, Ars Technica was proud to sponsor “the first AI-written sci-fi script:” As explained in The Guardian, a recurrent neural network “was fed the Read More ›
