#32How long until society becomes Gattaca? Sorry citizen our “AI” has detected genetic anomalies you will be a disposable factory worker. The rich would surely pay for their children to be genetically altered.
What exactly guarantees that reality? Why can't these tools be used for good moving forward? e.g. detecting heart problems. Seems a little arbitrary to spin technological advancements as progress towards some inevitable dystopian AI-driven future.
I'd say it's fairly certain given a capitalist society and human nature. Remember pre-existing conditions and insurance denials pre-Obamacare? Yeah, insurance companies would love to get their hands on your genetic data and tailor rates to your likelihood of future healthcare cost. At the same time, rich parents pretty much always pursue any advantage they can for their children - that's why private schools and homes in good school districts are so expensive. Add in the fact that we already have massive inequality and dropping social mobility in the US, and a Gattaca-like future starts looking pretty damn likely.

#33One heartbeat? That's nothing. I can detect heart failure from zero heartbeats (but only zero heartbeats)
Re: AI Detects Heart Failure from One Heartbeat: Study
#34I'm going to sound like a skeptical jerk here, but 490,000 heartbeats is how many patients? From what I recall these public ECG datasets are like 20 patients who underwent longitudinal ECGs. 500k heart beats is like 5 person-days of ECG recordings. Ninja Edit: N=~30 patients. For something like ECGs which are readily available, they really should have tried to get more patients. A single clinic anywhere does than 30…
I mean, the issue would be in the structure of the cross validation approach. Say, set training = 29, test = 1, build models etc: how well did you do on the one? Rinse, wash hands, repeat 30x. This is your cross validation error rate.
Its not that difficult.

#35Wasn't a similar claim made about an AI detecting skin cancer from moles? Once the AI was deployed in the real world is failed miserably. I think it was a ton of false-positives because it was trained on images where cancerous moles all had images of rulers with them and the benign ones didn't have rulers in the image. So it just picked up on the ruler as a cancer indicator.
Would you happen to have a source for that story? My workplace has really swallowed the AI Kool-Aid lately, so I would like to have some cautionary counterexamples to demonstrate potential pitfalls of the technology.
It's got a lot of interesting applications for our field which I am excited about, but there seems to be a tendency among non-experts to consider it a magic bullet that can solve any sort of problem. In particular, I am concerned about applications where conventional approaches have already converged on an optimal solution that's used operationally, but somebody wants to throw AI at it because they thought it might be cool without first understanding the implications.

#36So first clarification is that heart failure != heart attack. Heart failure is a chronic condition where the heart is unable to pump hard enough to keep blood flowing through the body. Typically results in blood pooling in the leg, shortness of breath, etc. The study avoids the obvious pitfall, which is to put different slices of one patient's data into both training and test. The press also reports the training accu…
Well, the issues are fundamental to the calculation of their error statistics. These models and their error rates are, well, crap. If any of the people in my group came back to me with this as an error assessment, they'd be re-doing their work.

Yes, Table 5 shows that N is 18 without CHF and 15 with CHF. These come from separate data sets that have EKG data sampled at different frequencies.
Basically, they took 18 electrocardiographic tracings (sampled at 128 Hz) from participants without CHF, of whom 13 come from women. They compared them to 15 electrocardiographic tracings (sampled at 250 Hz) from participants with CHF, of whom 4 come from women.
Hard to even know where to begin with this one.

#40last year we've started to cloud recording obstetric ultrasound videos. we add more than 17,000 ultrasound exams to our platform each month. It's probably the largest dataset in the world of obstetric ultrasounds videos (~ 300,000 exams). reading news like this makes me think about how we can explore our dataset using ML/AI and help produce better diagnosis. I have no idea how (We're not an AI company). If someone he…
You absolutely can. Hitting you up now.
