jm'The creator of the YOLO algorithms, which (along with SSD) set much of the path of modern object detection, has stopped doing any computer vision research due to ethical concerns.'

jm“There’s this idea in society that finding more cancers is always better, but it’s not always true,” Adewole Adamson, a dermatologist and assistant professor at Dell Medical School, tells The Verge. “The goal is finding more cancers that are actually going to kill people.” But the problem is “there’s no gold standard for what constitutes cancer.”
As studies have found, you can show the same early-stage lesions to a group of doctors and get completely different answers about whether it’s cancer. And even if they do agree that that’s what a lesion shows — and their diagnoses are right — there’s no way of knowing whether that cancer is a threat to someone’s life. This leads to overdiagnosis, says Adamson: “Calling things cancer that, if you didn’t go looking for them, wouldn’t harm people over their lifetime.”
As soon as you do call something cancer, it triggers a chain of medical intervention that can be painful, costly, and life-changing. In the case of breast cancer, that might mean radiation treatments, chemotherapy, the removal of tissue from the breast (a lumpectomy), or the removal of one or both breasts entirely (a mastectomy). These aren’t decisions to be rushed.
Overdiagnosis, he says, “is a problem for a lot of different cancers; for prostate, melanoma, breast cancer, thyroid. And if AI systems become better and better at finding smaller and smaller lesions you will manufacture a lot of pseudo-patients who have a ‘disease’ that won’t actually kill them.”

Facial recognition technologies, used in the identification of suspects, negatively affects people of color. To deny this fact would be a lie. And clearly, facial recognition-powered government surveillance is an extraordinary invasion of the privacy of all citizens — and a slippery slope to losing control of our identities altogether. There’s really no “nice” way to acknowledge these things.
I’ve been pretty clear about the potential dangers associated with current racial biases in face recognition, and open in my opposition to the use of the technology in law enforcement. As the black chief executive of a software company developing facial recognition services, I have a personal connection to the technology, both culturally and socially.
Having the privilege of a comprehensive understanding of how the software works gives me a unique perspective that has shaped my positions about its uses. As a result, I (and my company) have come to believe that the use of commercial facial recognition in law enforcement or in government surveillance of any kind is wrong — and that it opens the door for gross misconduct by the morally corrupt.

jmWe propose a new real-world attack against the computer vision based systems of autonomous vehicles (AVs). Our novel Sign Embedding attack exploits the concept of adversarial examples to modify innocuous signs and advertisements in the environment such that they are classified as the adversary's desired traffic sign with high confidence. Our attack greatly expands the scope of the threat posed to AVs since adversaries are no longer restricted to just modifying existing traffic signs as in previous work. Our attack pipeline generates adversarial samples which are robust to the environmental conditions and noisy image transformations present in the physical world. We ensure this by including a variety of possible image transformations in the optimization problem used to generate adversarial samples. We verify the robustness of the adversarial samples by printing them out and carrying out drive-by tests simulating the conditions under which image capture would occur in a real-world scenario. We experimented with physical attack samples for different distances, lighting conditions, and camera angles. In addition, extensive evaluations were carried out in the virtual setting for a variety of image transformations. The adversarial samples generated using our method have adversarial success rates in excess of 95% in the physical as well as virtual settings.

jm“The Volvo XC60 comes with City Safety as a standard feature however this does not include the Pedestrian detection functionality [...] The pedestrian detection feature [...] costs approximately $3,000.
However, there's another lesson here, in crappy car UX and the risks thereof:
But even if it did have the feature, Larsson says the driver would have interfered with it by the way they were driving and “accelerating heavily towards the people in the video.” “The pedestrian detection would likely have been inactivated due to the driver inactivating it by intentionally and actively accelerating,” said Larsson. “Hence, the auto braking function is overrided by the driver and deactivated.” Meanwhile, the people in the video seem to ignore their instincts and trust that the car assumed to be endowed with artificial intelligence knows not to hurt them. It is a sign of our incredible faith in the power of technology, but also, it’s a reminder that companies making AI-assisted vehicles need to make safety features standard and communicate clearly when they aren’t.
