​​iRobot with poop detection

iRobot (company building cleaning house robots) had a problem with robots regarding pet poops. So they built a special model along with physical models of poop to test the product.

New attempt at proving P≠NP

Martin Dowd published a 5-page paper claiming to contain a proof that P ≠ NP. This is a fundamental question, comparing quickly checkable against quickly solvalble problems.

Basically, proving P != NP would mean that there will be unlimited demand alphago-like solutions in different spheres, because that will mean (as a scientific fact) that there are problems not having fast [enough] analytical solutions.

​​Counting Happiness and Where it Comes From

Researches asked 10 000 Mechanical Turk participants to name 10 things which are making them happy, resulting in creation of HappyDB.

And since that DB is open, Nathan Yau analyzed and vizualized this database in the perspective of subjects and actions, producing intersting visualization.

Hope that daily reading @opendatascience makes you at least content, if not happy.

​​SwinIR: Image Restoration Using Swin Transformer

Image restoration is a long-standing low-level vision problem that aims to restore high-quality images from low-quality images (e.g., downscaled, noisy, and compressed images). While state-of-the-art image restoration methods are based on convolutional neural networks, few attempts have been made with Transformers, which show impressive performance on high-level vision tasks.

The authors use a model SwinIR based on the Swin Transformers. Experimental results demonstrate that SwinIR outperforms state-of-the-art methods on different tasks (image super-resolution, image denoising, and JPEG compression artifact reduction) by up to 0.14~0.45dB, while the total number of parameters can be reduced by up to 67%.

​​Summarizing Books with Human Feedback

#OpenAI fine-tuned #GPT3 to summarize books well enough to be human-readable. Main approach: recursively split text into parts and then meta-summarize summaries.

This is really important because once there will be a great summarization #SOTA we won't need editors to write posts for you. And researchers ultimatively will have some asisstance interpreting models' results.

RoBERTa English Toxicity Classifier

We have released our fine-tuned RoBERTa based toxicity classifier for English language on🤗:
https://huggingface.co/SkolkovoInstitute/roberta_toxicity_classifier

The model was trained on the merge of the English parts of the three datasets by Jigsaw. The classifiers perform closely on the test set of the first Jigsaw competition, reaching the AUC-ROC of 0.98 and F1-score of 0.76.
So, you can use it now conveniently for any of your research or industrial tasks☺️

It's All in the Heads: Using Attention Heads as a Baseline for Cross-Lingual Transfer in Commonsense Reasoning

Researchers from #Yandex have discovered that the reasoning capabilities of cross-lingual Transformers are concentrated in a small set of attention heads. A new multilingual dataset could encourage research on commonsense reasoning in Russian, French, Chinese and other languages.

We Have Published a Model For Text Repunctuation and Recapitalization

The model works with SINGLE sentences (albeit long ones) and:

- Inserts capital letters and basic punctuation marks (dot, comma, hyphen, question mark, exclamation mark, dash for Russian);
- Works for 4 languages (Russian, English, German, Spanish) and can be extended;
- By design is domain agnostic and is not based on any hard-coded rules;
- Has non-trivial metrics and succeeds in the task of improving text readability;

​​A Recipe For Arbitrary Text Style Transfer with Large Language Models

Text style transfer is rewriting text to incorporate additional or alternative stylistic elements while preserving the overall semantics and structure.

Large language models are trained only for continuation, but recently many approaches showed that it is possible to perform other NLP tasks by expressing them as prompts that encourage the model to output the desired answer as the continuation.

The authors present a new prompting method (augmented zero-shot learning), which frames style transfer as a sentence rewriting task and requires only natural language instruction.

There are many great examples in the paper and on the project page - both formal and informal.
For example, "include the word "oregano"" and "in the style of a pirate".
