The Code for Facial Identity in the Primate Brain

This paper showed that facial images can be reconstructed from a simple linear model using responses of only ~200 visual neurons recorded from a monkey. This approach uses "face cells" which are encoding how much a face differs from average in particular ways ("eigenface dimensions").

Test-Driven Data Analysis

TDD is an approach to software development, suggesting that tests are essential part of the process. Over the years TDD have shown that it is required to maintain a good code base and the most common requirement for the lasting project.

Test driven approach can be maintain with data analysis too, with the reproducible research approach or TDDA, which is suggested by the latter link.

Dynamic Meta-Embeddings for Improved Sentence Representations

While one of the first steps in many NLP systems is selecting what pre-trained word embeddings to use, we argue that such a step is better left for neural networks to figure out by themselves. To that end, we introduce dynamic meta-embeddings, a simple yet effective method for the supervised learning of embedding ensembles, which leads to state-of-the-art performance within the same model class on a variety of tasks. We subsequently show how the technique can be used to shed new light on the usage of word embeddings in NLP systems.
