Manipulating Machine-Learning Systems through the Order of the Training Data

2 Shares

Yet another adversarial ML attack:

Most deep neural networks are trained by stochastic gradient descent. Now “stochastic” is a fancy Greek word for “random”; it means that the training data are fed into the model in random order.

So what happens if the bad guys can cause the order to be not random? You guessed it—all bets are off. Suppose for example a company or a country wanted to have a credit-scoring system that’s secretly sexist, but still be able to pretend that its training was actually fair. Well, they could assemble a set of financial data that was representative of the whole population, but start the model’s training on ten rich men and ten poor women drawn from that set ­ then let initialisation bias do the rest of the work.

Does this generalise? Indeed it does. Previously, people had assumed that in order to poison a model or introduce backdoors, you needed to add adversarial samples to the training data. Our latest paper shows that’s not necessary at all. If an adversary can manipulate the order in which batches of training data are presented to the model, they can undermine both its integrity (by poisoning it) and its availability (by causing training to be less effective, or take longer). This is quite general across models that use stochastic gradient descent.

Research paper.

NY State is Giving Out Hundreds of Robots as Companions For the Elderly

1 Share
The state of New York will distribute robot companions to the homes of more than 800 older adults. From a report: The robots are not able to help with physical tasks, but function as more proactive versions of digital assistants like Siri or Alexa -- engaging users in small talk, helping contact love ones, and keeping track of health goals like exercise and medication. The scheme is being organized by the New York State Office for the Aging (NYSOFA), and is intended to help address the growing problem of social isolation among the elderly. An estimated 14 million Americans over the age of 65 currently live alone, and this figure is projected to increase over the next decade as the boomer generation ages. Studies have suggested that long-term loneliness is as damaging to an individual's health as smoking.

This Is Truly the Best Way to Eat a Grapefruit

1 Share

For most of my life, I thought I didn’t like grapefruit. I loved the flavor—grapefruit seltzer is the tops—and the scent, but the actual fruit? Too bitter, even with sugar dumped on top (how my dad always used to eat it) and too messy (the number of times I squirted myself in the eye with citrus juice while attempting…
