​​Can evolution be the Master Algorithm?

Fun AutoML-Zero experiments: Evolutionary search discovers fundamental ML algorithms from scratch, e.g., small neural nets with backprop.

Genetic programming learned operations reminiscent of dropout, normalized gradients, and weight averaging when trying to evolve better learning algorithms.

​​A Deep Learning Approach to Antibiotic Discovery

A new antibiotic was found using DL, claimed to be effective against several bacteria resistant to existing antibiotics on mice in the lab.

The problem with finding good antibiotics is potential molecule space is prohibitively large to test all possible molecules in the lab. They train a model that receives the molecule as a graph and tries to predict how effective it is against E. coli.

For every edge, they run single-layer NN receiving activations and features of input node and edge features, and producing new activations for the edge. Activations of the node = sum of all incoming edge activations. Overall activations vector for molecule = sum of all nodes.

Finally, there's a 2-layer NN receiving overall vector for the molecule + some standard handcrafted features with a binary classification output, trained end-to-end on 2.3K molecules. Then, they predict on the dataset of 6K molecules being in different stages of the investigation.

They looked at the top 51 predictions and manually ranked them by not being similar to the training dataset, being far in the investigation stage and scoring low on the external toxicity model. The top pick is what they called Halicin and tested in the lab.

​​What is Trending on Wikipedia? Capturing Trends and Language Biases Across Wikipedia Editions

The authors propose an automatic evaluation and comparison of the browsing behavior of Wikipedia readers that can be applied to any language editions of Wikipedia. Focused on English, French, and Russian languages during the last four months of 2018.

They approach consists of the following steps:
– extraction of a sub-network of trending Wikipedia articles and identification of trends
– extraction of keywords from the summaries of every Wikipedia article in the sub-network and weighting according to their importance
– labeling of the trends with high-level topics using the extracted keywords

​​Photofeeler-D3

tl;dr: predict first impressions from a photo or video

some interesting items of note:
- notice how Smart is the dominant trait until he takes off his glasses
- when the glasses are taken off, his Attractive score rises
- there’s a quick dip in scores every time he blinks
- the overall top scores result from the genuine smile at the very end!

​​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.
