Counterfactual Invariance to Spurious Correlations: Why and How to Pass Stress Tests

arXiv.org Machine Learning

Informally, a `spurious correlation' is the dependence of a model on some aspect of the input data that an analyst thinks shouldn't matter. In machine learning, these have a know-it-when-you-see-it character; e.g., changing the gender of a sentence's subject changes a sentiment predictor's output. To check for spurious correlations, we can `stress test' models by perturbing irrelevant parts of input data and seeing if model predictions change. In this paper, we study stress testing using the tools of causal inference. We introduce \emph{counterfactual invariance} as a formalization of the requirement that changing irrelevant parts of the input shouldn't change model predictions. We connect counterfactual invariance to out-of-domain model performance, and provide practical schemes for learning (approximately) counterfactual invariant predictors (without access to counterfactual examples). It turns out that both the means and implications of counterfactual invariance depend fundamentally on the true underlying causal structure of the data. Distinct causal structures require distinct regularization schemes to induce counterfactual invariance. Similarly, counterfactual invariance implies different domain shift guarantees depending on the underlying causal structure. This theory is supported by empirical results on text classification.


Low-cost Stereovision system (disparity map) for few dollars

arXiv.org Artificial Intelligence

The paper presents an analysis of the latest developments in the field of stereo vision in the low-cost segment, both for prototypes and for industrial designs. We described the theory of stereo vision and presented information about cameras and data transfer protocols and their compatibility with various devices. The theory in the field of image processing for stereo vision processes is considered and the calibration process is described in detail. Ultimately, we presented the developed stereo vision system and provided the main points that need to be considered when developing such systems. The final, we presented software for adjusting stereo vision parameters in real-time in the python language in the Windows operating system.


Omnizart: A General Toolbox for Automatic Music Transcription

arXiv.org Artificial Intelligence

We present and release Omnizart, a new Python library that provides a streamlined solution to automatic music transcription (AMT). Omnizart encompasses modules that construct the life-cycle of deep learning-based AMT, and is designed for ease of use with a compact command-line interface. To the best of our knowledge, Omnizart is the first transcription toolkit which offers models covering a wide class of instruments ranging from solo, instrument ensembles, percussion instruments to vocal, as well as models for chord recognition and beat/downbeat tracking, two music information retrieval (MIR) tasks highly related to AMT.

Will Robots and Artificial Intelligence Take Your Job?

#artificialintelligence

A 2014 Pew Research Center study asked nearly 2,000 experts about how technologies like robotics and artificial intelligence (AI) would affect jobs. About half said a significant number of jobs, both blue- and white-collar, would be gone, potentially resulting in massive unemployment, income inequality and a complete breakdown of social order. While we're used to factory jobs being lost, the rise of AI will be vastly more far-reaching. In "18 Jobs That Are Most Likely to Be Killed off by Computers," we listed jobs in jeopardy, ranging from equipment operators to physicists. Computers equipped with AI are now even writing articles, so journalism jobs could also one day follow dial phones and camcorders into history.

Tucker: The left uses partisan politics posing as science

FOX News

'Tucker Carlson Tonight' host examines how the left uses'science' to push their agenda This is a rush transcript from "Tucker Carlson Tonight," May 28, 2021. This copy may not be in its final form and may be updated. At some point, though it's hard to imagine now, the current revolution will end. Ultimately, all revolutions do end, they can't be sustained. And when ours does, we'll wake up one morning in a country where we don't have to lie about everything all the time, where Math is allowed, where we can acknowledge the profound and inherent differences between men and women without being fired for it. The question is, when it does come, what will be left of our society? We can't know the answer in detail. We hope that reason remains. Reason, logic, the ability to think clearly and rationally. That's the one thing we can't lose. We're going to need it to rebuild. That's why of all the moral atrocities being committed at the moment in the name of equity and inclusion, it is the relentless attacks on science that should command our special attention. So for the next hour, we're going to consider those attacks in some detail and we are going to start with America's response to the COVID pandemic. When the coronavirus first arrived in our country last winter, most Americans uncritically accepted what the authorities said about it. They thought they could trust the people in charge. Few imagined that our leaders would leverage a public health emergency for their own political gain. That seemed like the one line that even politicians wouldn't cross, and yet almost immediately, they crossed it.

How we made Short Circuit, by Steve Guttenberg and John Badham

#artificialintelligence

The second I read the script, about a robot becoming self-aware after being struck by lightning, I put it down and said: "This is a hit." It was a timeless story about an underdog, a friendship and being an outsider. It also had John Badham as director who had done Saturday Night Fever and War Games. He knew how to make a movie like this work. It felt like a piece that was going to be around a long time and I grabbed it with both hands.
