Comment Perfect timing (Score 2) 25

The timing on this is perfect. A group I'm in is working on a book and right now going through trying to get copyright permission on all of the images we want to use (and sometimes you can't get it without paying fees, or can't get in touch with the author). Having such a huge wealth of public domain images all together on one seemingly well-designed search engine will be great for finding substitutions.

Too bad there's no ready substitution for figures from papers, however :P For a nonprofit book a lot of the big servers charge around $50 per image. Which for a full length book (dozens of figures) is thousands of dollars. Most authors are very nice about granting permission, but the journals are all about cash.

And if the 1998 paper, then why? Have I defended that paper in this thread? Beyond foregrounding the fact that the work which has superseded it has "more or less" confirmed the original findings? I merely noted that calling Dr Mann "really really bad at statistics" was "perhaps" to overstate matters.

Why? Mainly because it most clearly demonstrates the issue.

And maybe you are right about his statistical skill, but saying he is really really bad at statistics is actually being generous to him. If he knew what he was doing, then he was actively trying to deceive people, which is far worse.

The speculation is that in the tree rings that diverged (not all did) it had to do with pollution. Mann is not a tree ring specialist. He used tree ring data from scientists who are. He followed the recommendation from the scientists who produced the data he used to not use the divergent data.

I think that's an explanation I read on real-climate somewhere once. There are actually a number of hypotheses, but it's not really clear.

Don't be an ass mate........Which is not to say I accept that statement (from memory, and I'm not minded to go to the effort and check, the problem was with a particular sub-sample of tree-ring data)

It's hard to not be an ass towards someone who is willfully ignorant. I'm willing to forgive a lot of things.

The only saving grace you can grant Mann here is that he didn't hide what he did in his paper. His error bars should have taken into account the fact that tree rings don't match thermometers, but well, apparently he missed the topic of error bars in his statistics class or something. Oh well.

It's more like seeing what minor tweaks they're making to the previous model, and what things they're taking away that were good.

Given the (necessary) quick turn-around, I imagine this will be even more the case than is usual.

1) Make sure the battery won't explode or catch fire
2) Iterate the quick & easy stuff like the camera and maybe the display panel
3) There is no step 3

I'm still not following. Do you mean "racist software" in the literal AI sense that the software is thinking like a racist human being?

There is no point in pondering what nut-jobs think, so stop wasting your time on it.

You mean like a spot-light to the face? Then you get squinty photos.

Look at how they do photo-shoots for models and you'll understand because that kind of lighting is what's needed.

One probably has to manually adjust the gamma levels instead

A) that won't help
B) the computer vision software already filters images in multiple ways to get the optimal contrast.

Either train the staff or...

The staff where? All staff everywhere? We're going to make cops into photographers now? Also, what about video camera footage? There are two sides of the equation and your introductory suggestion is unrealistic at best.

have the photos sent to an adjustment lab

They are all digital and CV software already filters images. The problem isn't tweaking the images, it's that there isn't enough information in the images.themselves.

Before you jump to conclusions about "racist software"...

What exactly are the accusations you are defending against?

I think you missed the keyword in there: before. If you didn't think it was coming, this is the internet, some people think the Earth is flat and the US government "did 9/11", so it's only a matter of time before someone claims the software is racist.

I will add that bias is not necessarily conscious racism; it could be those who build the equipment and/or train staff on using the equipment are mostly used to dealing with people of a certain ethnic group.

You misunderstand when I wrote, "have their face very well lit up," i mean that you need to have lights specifically for lighting their face. A bunch of pictures were from the DMV which isn't exactly a photography studio. A better solution might be to use polarized light and a polarized light to joint the red, green and blue that are already on the CCD and use the polarized light to produce a 3d model of the person's face. If it works with skin, it would be pefect.
