# Motivations

The Machine Learning community is currently experiencing a reproducibility crisis and a reviewing crisis [Littman, 2021]. Because of the highly competitive and noisy reviewing process of ML conferences [Tran et al., 2020], researchers have an incentive to oversell their results, slowing down the progress and diminishing the integrity of the scientific community. Moreover with the growing number of papers published and submitted at the main ML conferences [Lin et al., 2020], it has become more challenging to keep track of the latest advances in the field.

Blog posts are becoming an increasingly popular and useful way to talk about science [Brown and Woolston, 2018]. They offer substantial value to the scientific community by providing a flexible platform to foster open, human, and transparent discussions about new insights or limitations of a scientific publication. However, because they are not as recognized as standard scientific publications, only a minority of researchers manage to maintain an active blog and get visibility for their efforts. Many are well-established researchers (Francis Bach, Ben Recht, Ferenc Huszár, Lilian Weng) or big corporations that leverage entire teams of graphic designers designer and writers to polish their blogs (Facebook AI, Google AI, DeepMind, OpenAI). As a result, the incentives for writing scientific blog posts are largely personal; it is unreasonable to expect a significant portion of the machine learning community to contribute to such an initiative when everyone is trying to establish themselves through publications.

Our goal is to create a formal call for blog posts at ICLR to incentivize and reward researchers to review past work and summarize the outcomes, develop new intuitions, or highlight some shortcomings. A very influential initiative of this kind happened after the second world war in France. Because of the lack of up-to-date textbooks, a collective of mathematicians under the pseudonym Nicolas Bourbaki [Halmos 1957], decided to start a series of textbooks about the foundations of mathematics [Bourbaki, 1939]. In the same vein, we aim at providing a new way to summarize scientific knowledge in the ML community.

# Our Idea: Blog post Conference Track

Due to the large diversity of topics that can be discussed in a blog post, we decided to restrict the range of topics for this call for blog posts. We identified that the blog posts that would bring to most value to the community and the conference would be posts that distill and discuss previously published papers.

## Call for blog posts on papers previously published at ICLR

The call for blog post would take the following form:

- Write a post about a paper previously published at ICLR, with the constraint that one cannot write a blog post on work that they have a conflict of interest with. This implies that one cannot review their own work, or work originating from their institution or company. We want to foster productive discussion about ideas, and prevent posts that intentionally aim to help or hurt individuals or institutions.

- Blogs will be peer-reviewed (double-blind, see Section 2.5) for quality and novelty of the content: clarity and pedagogy of the exposition, new theoretical or practical insights, reproduction/extension of experiments, etc.

- The posts will be published under a unified template (see Section 2.4 and Section 2.5) and hosted on the conference website or our own Github page.

## Positive Impact for the Community

We believe having this call for blog posts as a conference track would increase the posts’ visibility, impact, and credibility, while simultaneously providing benefits to the conference.

- Adoption: we think that, with the conference’s stamp, such a format will be more broadly recognized and adopted by the community.

- Accessibility: maintaining a blog is time consuming , and requires many blog posts to gain a stable following. By allowing researchers to publish a single post, we will permit occasional blog writers to publish their ideas, something that is relatively impossible right now. Moreover, it will make this format accessible to more independent/junior blog writers that do not have a company or a research lab to support them.

- Synchronization: the fast evolving field of ML advances at the paces of its conferences. By following the same pace the blog posts will add value and momentum to the conference. It will benefit from the same advantages of conferences with respect to scientific journals: faster publication process and cross-fertilization of ideas.

## Positive Impact for the Conference

We develop the potential positive impact of a blog post track for the conference itself:

- Increases the value of the papers submitted to ICLR: blog posts will discuss previously published papers, thus increasing their visibility and quality.

- Incentivizes researchers to submit their best research to ICLR: high quality work will likely get highlighted in future years in a blog post.

- Improves reproducibility and transparency: the blog post track will identify and publicly document pitfalls and “tricks” that were not clearly communicated in the original publication.

- Provides a scientific value by itself: such blog posts will reproduce and extend results of previously published papers. They will distill important theoretical and practical ideas improving their adoption and impact.

- Tests of time: this track will provide a sort of crowd-sourced test of time at a shorter timescale than the current test of times awards.

- Promotes accessibility: because many of this track’s blog posts will vulgarize past content, this track will make the conference broadly more accessible (to students, non-natives, and, more generally, non-experts in the field).

## Submission Format

Our goal is to avoid heavily engineered, professionally-made blog-posts—Such as the “100+ hours” mentioned as a standard by the Distill guidelines—to entice ideas and clear writing rather than dynamic visualizations or embedded javascript engines.

As a result, we restrict submissions to the Markdown format. We believe this is a good trade-off between complexity and flexibility. Markdown enables users to easily embed media such as images, gifs, audio, and video as well as write mathematical equations using MathJax, without requiring users to know how to create HTML web pages. This (mostly) static format is also fairly portable; users can download the blog post without much effort for offline reading or archival purposes. More importantly, this format can be easily hosted and maintained through GitHub.

## Submission Process

A full copy of the track’s blogs will always be publicly available as a GitHub repository (mock-up link).

The process for creating and submitting a blog post is as follows:

1. Entrants will fork this repository and make their fork private. Failure to do so will result in the submission being rejected, as it breaches the double-blind review process.

2. Users will modify their fork as they see fit; they will add their post along with any media files it might require. Since this is a full fork, they will be able to view their own copy of the blog. This means that they will be able to see exactly how their post will look and behave on the main website.

3. Once completed, entrants will anonymize their blog post (i.e. strip their name, affiliation, etc).

4. Entrants will download a ZIP of their anonymized fork (see figure below), and submit the ZIP to our OpenReview venue.

1. Once accepted, entrants will de-anonymize their post, make their fork public again, and make a Pull Request on Github from their fork to the main blog, allowing us to pull in their new blog post in a transparent way.

Once the submission period has ended, the GitHub repository of our track will be temporarily made private for the duration of the conference, allowing the conference to host the website. After the conference, the GitHub repository will be made public again to allow viewers to fork and download its contents.

## The potential Pitfalls of our Blog Post Track

In this section we identify potential issues arising with such a track and explain how to mitigate them:

1. Adversarial Blog Posts: Since the guidelines are to write a blog post on a previously published paper, one may expect some researcher to try to use bad faith arguments to criticize a concurrent paper through one of these blog post. We do not think this will happen, because these blog posts will be public and thus researchers would discredit themselves by using bad faith arguments.

2. Too many/few submissions: As this is a new track, it may be difficult to predict the volume of submissions. The fact that there are currently many independent blog posts on the web is a good indicator that there will be positive interest. To get a better estimate of the volume of potential submissions, we intend to leverage social media to gauge the interest of the ML community in such a track; this will allow us to gather a large enough reviewing committee.

3. Reviewing: Once again as this is a new track, it may be unclear how to judge blog posts during a review process. We will recruit a large reviewing committee and define clear guidelines for the reviewing process. Our primary focus will be on the originality of the perspective and the novelty of the ideas, insights, and experiments. For instance, posts that reuse less content from the original paper (results, direct quotes) will be scored more favourably than those that use more.

4. Too many posts on the same paper: We may mitigate this by only selecting a small numbers of blog posts on the same paper. This could actually be a strength since this can encourage discussion and highlight different perspectives on the same work. Moreover, we could explicitly state that we will have this hard limit (e.g., accepting a maximum of 3 blog posts on the same paper) to entice researchers to submit blog posts on papers that have less visibility.

# Related Initiatives

We mainly address our difference with respect to Distill, the ML Retrospectives Workshop, a Tutorial Track, and other workshops discussing alternative formats for publications.

#### Distill.

Created in 2016, Distill is an online scientific journal based on blog post publications. We address our differences with respect to Distill:

- Visualizations: Blog posts should take advantage of the fact that they’re not paperbound, and use innovative visualisations. But the process of creating the intricate, dynamic visualisations associated with Distill posts is a daunting for most authors. Creating blog posts should be more easily accessible to newer authors and researchers. Sometimes, being able to embed videos and gifs is enough.

- Content: Distill does not target the same type of content as our track. Distill aims at presenting new research, and at making this research more accessible. We want our blog post track to incentivize researchers to revisit and discuss on other researcher’s works, in a more natural way than scientific papers allow. Such a practice would undoubtedly be useful for the community, both as a short-term “test of time”, and also as a way to extract the key ideas from lengthy articles.

- Limited adoption by the community: we believe that since Distill is not associated with a big conference track, its widespread adoption is hindered. This lack of association confines it to a small subset of the community that is already familiar with blog posts.

- Leveraging the momentum of the conference: Distill describes itself as a scientific journal. A large amount of the publications in the ML community are conference papers. A blog post track that follows conferences would be better suited to follow the pace of the community.

#### ML-Retrospective Workshop.

A recurrent workshop in the ML community is the ML Retrospectives Workshop (NeurIPS 2019, 2020 and ICML 2020). This workshop is a venue for researchers to talk about their previous work in a more open and transparent way. More precisely, emphasis has recently been put on addressing:

- Flaws or mistakes in the paper’s methodology

- Limitations in the applicability of the work

- Changes in understanding or intuition

We share the ultimate goal of “making research more human”, but with a completely different format. We believe that the constraint to write about someone else’s work using natural language will channel fruitful discussions and provide more visibility to previously published papers.

#### Tutorial Track.

We believe that our proposed blog post track differentiates itself from a tutorial track because tutorials operate at different scales. On the one hand, a tutorial regarding a whole topic (e.g. GANs, adversarial examples, Random matrix theory in ML) contains a long talk, slides, and potentially exercises to get familiar with the topics. It is usually made by a team of expert researchers on the topic. On the other hand, the call for blog posts we propose focuses on a single publication. It regards a single paper that can concern a more precise and recent topic (e.g., a specific paper that addresses mode collapse on GANs, a novel technique to perform adversarial training, etc.) and could be written by a single researcher (once again making it more accessible to junior researchers).

#### Previous workshops on rethinking publication formats.

Recently, the Rethinking ML Papers Workshop at ICLR 2021 fuelled the discussion (see references therein for related past workshops). The presenters discussed the importance of accessibility, web demonstrations, visualization and blog posts (among others). One particularly related discussion was the talk by Lilian Weng (time=4h25mins) on the usefulness of blog posts to get up-to-date with the field of ML.

In alignment with these initiatives, this new track is another step in the direction of making research more human.
