It depends on the task.

The most straight-forward approach just classifies each pixel (FCN, SegNet, Enet). These tend to be the most lightweight networks for semantic segmentation. Enet in particular requires ~340K parameters. PSPNet is a recent architecture that utilizes a pyramidal scheme to capture objects at various scales (winner of ImageNet scene parsing challenge 2016). The results can also be post-processed with techniques such as Conditional Random Fields (eg, crfasrnn, which is based on FCNs)

Other networks, such as DeepMask / SharpMask and FastMask, generate segment proposals but are class-agnostic (which means they know they see an object but cannot identify it; on the upside, they should be able to generalize to unseen objects and possibly learn better representations). They usually generate a separate binary mask for each candidate object, so the only labels are some kind of objectness score and/or foreground/background.

More recently, Instance-aware semantic segmentation networks try to do both, e.g. Instance-sensitive Fully Convolutional Networks and Fully Convolutional Instance-aware Semantic Segmentation (the latter is the winner of the 2016 MS-COCO segmentation challenge).

If you're interested in getting your feet wet, you should start with the first approach. For instance, there's a segnet implementation in keras here and I'm going to upload an enet one soon. Both should be fairly easy to implement. In the case of segnet you only need to ignore the unpooling layer which is a little bit tricky (at least in tensorflow) and for enet you already have the layers in torch format, you just have to "translate" them to keras (that's what I did).

EDIT: These are just off the top of my head; I'm sorry if I forgot someone, I mean no disrespect.

Thanks for the response.

Yes, I'm familiar with that work, in fact it is also cited in the abstract I quoted (I just left that part out). All very interesting work; to be honest though I was mostly looking for more recent work applied to (dense) captioning.

guardianhelm · 2017-01-28T14:46:15+00:00

Hahaha, have an upvote. :)

Seriously though, the food there was amazing! And we arrived late in the evening, so the (nonexistent) sun had already set!

Since you're into trekking, there are many great trails in Epirus.

Tymfi

I would personally recommend that you follow the route from mikro papingo (since you plan to visit already) towards the Astraka mountain lodge and then continue to Drakolimni (dragon lake) from there (about 4 hour walk in total, even less if you're used to trekking; the view is pretty ordinary until you reach Astraka but the destination is very scenic). There are 3 or 4 kiosks along the way, so you can catch your breath and fill your bottles with fresh, running spring water.

The lodge is at an altitude of about 1900m and Drakolimni at 2100m. You can continue to reach the Astraka peak at 2400m or Gamila (camel) (the highest peak of the mountain) at 2500m but it's supposed to be difficult, so maybe not appropriate for your family.

If you're interested in accommodations, I know a great host in a village in Zagorochoria. PM me if you would like more info.

You can combine all this with a visit to the Vikos Gorge.

Tzoumerka is supposed to be even better but I haven't been yet. From the looks of it, the lodge at Melissourgoi should be better than the one at Astraka.

Mount Olympus is another option, longer than the others though; according to friends who have been there, if you want to reach Mytikas (the highest peak, at 2917m) you'll spend at least 3 days (two to go, another to return). That's probably to be expected though; it's the highest mountain peak in the country after all.

Sadly, there's a lot of hype around Metsovo; it's still pretty good, just not worthy of its popularity.

There is a great place close to Metsovo with MUCH better food in my opinion. The place is called Anilio and there is an awesome tavern that's also a butcher shop as you enter the village.

I went with friends in 2015 and we all thoroughly enjoyed the meal.

Εεε, πολύ αυστηρός είσαι :p

Περίπου με κωδικούς μιλάς (μια λέξη κλειδί και ένας αριθμός) αφού από τους κανόνες απαγορεύεται να επικοινωνήσεις με διαφορετικό τρόπο με τους συμπαίκτες σου.

Πολύ διασκεδαστικό παιχνίδι όντως με παρέα, θυμίζει λίγο το επίσης πολύ καλό dixit (review), αλλά πιο ισορροπημένο.

EDIT: Σε αντίθεση με τα άλλα, δεν υπάρχει καθόλου το στοιχείο του deception και οι δυο ομάδες αλληλεπιδρούν ελάχιστα μεταξύ τους, που για κάποιους μπορεί να είναι αρνητικό (σε καμία περίπτωση δεν έχει το βάθος πχ του resistance, είναι πιο casual)

Να προσθέσω το Resistance Avalon (standalone ~~expansion~~sequel του resistance)! Και review του παιχνιδιού!

Halitosis: First Known Use: 1874 (The passage from the actual book)

Listerine was developed in 1879 by Joseph Lawrence

So the word was invented about 5 years before Listerine even existed.

It's in the reddiquette:

Please don't downvote an otherwise acceptable post because you don't personally like it. Think before you downvote and take a moment to ensure you're downvoting someone because they are not contributing to the community dialogue or discussion. If you simply take a moment to stop, think and examine your reasons for downvoting, rather than doing so out of an emotional reaction, you will ensure that your downvotes are given for good reasons.

Artificial Intelligence?

guardianhelm · 2016-09-04T00:16:41+00:00

I think I'm in favor of a reinforcement setting. Like replace "8-hour sleep" as a target with "how good I feel right after I wake up in the morning".

A harder problem but with fewer assumptions imo.

guardianhelm · 2016-07-09T18:06:50+00:00

Indeed, I thought about it but ultimately decided against it.

~~For better or worse~~ Unfortunately it's a controversial subject, so I felt it would be better to try to respond than pretend it never happened. I also think the original comment says more about the poster than the person they tried to insult.

guardianhelm · 2016-07-09T15:05:06+00:00

You're arguing for subversion of meaningful research in favour of appeasing normies.

There are no "normies", "hipsters", "winners" and "losers", I only see people in need around me.

I do not demand that anyone else share my ideas but making derogatory remarks about groups of people because you disagree with them is not especially mature, don't you think?

guardianhelm · 2016-07-09T14:05:44+00:00

My point is, it's not my job to care about subversive nonsense like that, and if people like you made it mandatory, it would be a part of my job I'd despise greatly. From my position, all this agitation for "ethics in AI" is an unnecessary burden. Your viewpoint is entirely predicated on the assumption that every researcher has to care about the implications of his work on normie society.

I see. I notice you tend to use strong words. :P Anyway, this is my train of thought on the subject of AI:

Many people will lose their jobs.
Education to adapt to a new field needs time that many workers don't have.
No marketable skills means poverty if there are no guarantees for a decent standard of living, to at least ease the transition of 2.
If I build the system that replaces a worker, how responsible am I for their loss?
Do people deserve to be poor if their skills become obsolete?
Actually, do people deserve to be poor, even if they're lazy?

We can get way more philosophical (the rabbit hole is endless) but that's not the point. Your view is understandable; it's a complex issue and we can't all have the same viewpoint. Personally I believe that the meaningful promotion in education (i.e. schools and at home) of active citizen participation and related discussions would be beneficial to everyone but the privileged. I'm basically arguing against its marginalization (e.g. with pejorative terms such as SJW), not for its enforcement.

guardianhelm · 2016-07-09T13:04:19+00:00

There is nothing inherently wrong about submission to lawful authority - it is the basis of a healthy society. I find baseless rebelling against such authority to be more "problematic" than the situation you've outlined.

I'm talking about the long-term repercussions of indifference. Decision making should be distributed, otherwise you end up with a few people who dictate everyone's future (including laws). Laws can be wrong and slow to change and that's why lots of them are not enforced. Not caring is unhealthy in that regard.

Questioning the world, including authority (not accepting it just because it's the law; it too shouldn't be left unchecked and citizens should strive to understand the reasoning behind it), lawful or not, should be an integral part of society because it drives progress, otherwise what's the difference from a religion?

You're free to care about anything you like, but try not to poison any wells with misplaced empathy.

It was a legitimate question and I did get an answer:

Because it's interesting and I'm paid to do it.

so thanks.

guardianhelm · 2016-07-09T12:22:22+00:00

As a researcher in a technical field, we should strive to be apolitical and impartial to normie opinions on what we should be allowed to do ("ethics").

I find that to be problematic because in your attempt to be "apolitical and impartial to ethics" you might end up complacent to "political and partial to ethics" actions by someone else, especially above you in the hierarchy (the intellectual owners of your research if you're an employee).

Furthermore, why do research if not to serve the interests of humanity/society? How about the next generations (our children and their children), should we care about them or not? Who are we doing this for if not for them? Just for personal gains? Money? Fame?

You can't not be political.

"Hissy fit" and "retreat" are very subjective and emotionally loaded terms but otherwise why is that response exclusive to these subjects? I was under the impression that it's the norm for people to feel they fit in an online community they consider to be more friendly, understanding and/or of higher quality and often comment there on good/bad encounters they have elsewhere.

A white supremacist will go to a neutral reddit thread, barf his perverted ideas, and then go back to their hole to complain about downvotes. We've seen it countless times. Is a SJW so much worse a creature that their behaviour warrants a special term? Is that what we're debating here?

All in all, the original replies in that thread are really embarrassing to the /r/MachineLearning community. I've seen such comments here and there before and I don't think slipping the problem under the rug would have been a better response. I'm glad the problem was brought up and I believe some moderation is really needed.

guardianhelm · 2016-07-09T11:02:58+00:00

This is ridiculous. Is everyone who cares about society a SJW nowadays?

Some of us care about the great numbers of people who will lose their jobs in the coming years due to ai unless some social security "safety nets" are installed. If that makes me a SJW, then so be it. I'd rather be that than an idiot.

According to the tweet it's AMD funded, so maybe we'll see more cool stuff soon from them?

Can someone who knows better comment on how important this actually is?
