Are you exploring AI? If so, well then just try to at least socialize with others exploring AI once in a while 😉 We’re connecting people like you in the AI community together to discuss advancements, share opportunities, sketch ideas, and connect. This event is just social, so no laptop is required, but you will need one for the next workshop we’re planning 🙂 Bring an inquisitive mind and let’s see you there!
I thought it would be fun to cross-reference the ICLR 2017 (a popular Deep Learning conference) decisions (which fall into 4 categories: oral, poster, workshop, reject) with the number of times each paper was added to someone’s library on arxiv-sanity. ICLR 2017 decision making involves a number of area chairs and reviewers that decide the fate of each paper over a period of few months, while arxiv-sanity involves one person working 2 hours once a month (me), and a number of people who use it to tame the flood of papers out there. It is a battle between top down and bottom up. Lets see what happens.
Here are the decisions for ICLR 2017. A total of 491 papers were submitted, of which 15 (3%)will be an oral, 183 (37.3%) a poster, 48 (9.8%)were suggested for workshop and 245 (49.9%) were rejected. The accepted papers will be presented at ICLR on April 24–27 in Toulon, which I am really looking forward to. Look how amazing it looks:
But I digress.
On the other hand we have arxiv-sanity, which has a library feature. In short, any registered user can add a paper to their library, and arxiv-sanity will train a personalized SVM on bigram tfidf features of the full text of all papers to make content-based recommendations to the user. For example, I have a number of RL/generative models/CV papers in my library and whenever there is a new paper on these topics it will come up on top in my “recommended” tab. The review pool of arxiv-sanity is as of now a total of 3195 users — this is the number of people with an account that have at least one paper in the library. Together, these users have so far included 55,671 papers into their libraries, i.e. an average of 17.4 papers.
An important feature of arxiv-sanity is that users don’t just upvote papers with no repercussions. Adding a paper to your library has some weight, because that paper will influence your recommendations. You have an incentive to only include things that really matter to you in there. It’s clever right? No? Okay fine.
Long story short, I loop over all papers in ICLR and try to find them on arxiv using an exact match on the title. Some ICLR papers are not on arxiv, and some won’t get matched because the authors renamed them, or they contain weird characters, etc.
For example, lets look at the papers that got an oral at ICLR 2017. We get:
for oral, found 10/15 papers on arxiv with library counts: 64 Reinforcement Learning with Unsupervised Auxiliary Tasks 44 Neural Architecture Search with Reinforcement Learning 38 Understanding deep learning requires rethinking generalizatio... 28 Towards Principled Methods for Training Generative Adversaria... 22 Learning End-to-End Goal-Oriented Dialog 19 Q-Prop: Sample-Efficient Policy Gradient with An Off-Policy C... 13 Learning to Act by Predicting the Future 12 Amortised MAP Inference for Image Super-resolution 8 Multi-Agent Cooperation and the Emergence of (Natural) Langua... 8 End-to-end Optimized Image Compression
Here we see that we matched 10 out of 15 oral papers on arxiv, and the number next to each one is the number of people who have added that paper to their library. E.g. “Reinforcement Learning with Unsupervised Auxiliary Tasks” was in a library of 64 arxiv-sanity users. I also had to truncate some paper names because medium.com is improperly conceived and doesn’t let you change the font size.
Now lets look at the posters:

Some got a lot of love (149!), and some very little (0). For workshop suggestions we get:

and I won’t list all 200-something papers that were rejected, but lets look at the few that arxiv-sanity users really liked, but the ICLR ACs and reviewers did not:

Here is the full version, which was not truncated to fit here. There are a few papers on the top of this list that were possibly unfairly rejected.
Here’s another question — what would ICLR 2017 look like if it were simply voted on by the crowd of arxiv-sanity users (of the papers we can find on arxiv)? Here is an excerpt:
oral: 149 Adversarial Feature Learning 147 Hierarchical Multiscale Recurrent Neural Networks 140 Recurrent Batch Normalization 80 HyperNetworks 79 FractalNet: Ultra-Deep Neural Networks without Residuals 73 Zoneout: Regularizing RNNs by Randomly Preserving Hidden Acti... 64 Reinforcement Learning with Unsupervised Auxiliary Tasks 62 Unrolled Generative Adversarial Networks 60 Adversarial examples in the physical world 52 Adversarially Learned Inference ------------------------------------------------- poster: 49 Quasi-Recurrent Neural Networks 48 Do Deep Convolutional Nets Really Need to be Deep and Convolu... 46 The Predictron: End-To-End Learning and Planning 46 Neural Photo Editing with Introspective Adversarial Networks 44 Neural Architecture Search with Reinforcement Learning 43 An Actor-Critic Algorithm for Sequence Prediction 41 A Learned Representation For Artistic Style 39 RL^2: Fast Reinforcement Learning via Slow Reinforcement Lear... 38 Understanding deep learning requires rethinking generalizatio... 37 Structured Attention Networks 35 Understanding intermediate layers using linear classifier pro... 33 Mollifying Networks 33 Hierarchical Memory Networks 31 Learning in Implicit Generative Models 31 An Analysis of Deep Neural Network Models for Practical Appli... 30 DeepCoder: Learning to Write Programs ...
Again, the full listing can be found here. Note that in particular, some ICLR2017 papers that were rejected would have been almost an oral based on arxiv-sanity users alone, especially the Predictron, RL², “Understanding intermediate layers”, and “Hierarchical Memory Networks”. Conversely, some accepted papers had very little love from arxiv-sanity users. Here is a full confusion matrix:
And here is the confusion matrix in text, for each cell, together with the paper titles. This doesn’t look too bad. The two groups don’t agree on the orals at all, agree on the posters quite a bit, and most importantly there are very few confusions between oral/poster and rejection. Also, congratulations to Max et al. for “Reinforcement Learning with Unsupervised Auxiliary Tasks”, which is the only paper that both groups agree should be an oral 🙂
Finally, I read the following Medium post a few days ago: “Ten Deserving Deep Learning Papers that were Rejected at ICLR 2017”, by Carlos E. Perez. It seems that arxiv-sanity users agree with this post, and all papers listed there (including LipNet)(that we could also find on arxiv) would have been accepted by arxiv-sanity users.
An asterisk. There are several factors that skew these results. For example, the size of arxiv-sanity user base grows over time, so these results likely slightly favor papers that were published on arxiv later than earlier, as these would have come to more user’s attention as new papers on the site. Also, papers are not seen with equal frequencies — for instance if some paper gets tweeted out by someone popular, more people will see it, and more people might add it to their library. And finally, a good argument could be made that on arxiv-sanity “rich get richer”, because arxiv papers are not anonymous and celebrities could get more attention. In this particular case, ICLR 2017 is single-blind so this is not a differentiating factor.
Overall, my own conclusion from this experiment is that there is quite a bit of signal here. And we’re getting it “for free” from a bottom up process on the internet, instead of something that takes a few hundred people several months. And as someone who has had a good amount of long, painful, stressful, rebuttals back and forth on both submitting/reviewing sides that dragged on for multiple weeks/months, I say: Maybe we don’t need it. Or at the very least maybe there is a lot of room for improvement.
EDIT1: someone suggested the fun idea that we add up the number of citations of these papers in ICLR 2018 submitted/accepted papers, and see which ranking “wins” on that metric. Looking forward to that 🙂
Bring your own laptop, we’ll be diving into some artificial intelligence. Also, we’ll be looking at setting up some actual code with some of the libraries out there which we’ll build upon for with future meetups. We’ll be introducing a hello-world equivalent using the scikit framework for this session.
Whether you’re a beginner or an expert, all that matters is your interest in the subject, the rest will work itself out
