Morel: A functional language for data
For the past few months, I have been working on an experimental functional/data language called Morel. SQL has several deficiences relating to nested collections, higher-order functions and type system. After several months trying to figure out how to add these features to SQL, I noticed that they were basically the defining characteristics of a functional programming language. I figured, rather t
Toolz
PyToolz API Documentation¶ Toolz provides a set of utility functions for iterators, functions, and dictionaries. These functions interoperate well and form the building blocks of common data analytic operations. They extend the standard libraries itertools and functools and borrow heavily from the standard libraries of contemporary functional languages. Toolz provides a suite of functions which ha
tim philip williams :: Functional pearl: Nested Datacubes
Introduction Multi-dimensional aggregation and grouping are common forms of analysis traditionally done with SQL databases, OLAP tools (Online Analytical Processing) and/or Excel pivot tables. These traditional tools use a flat table representation, whereby tuples are mapped to measures without any nesting. Increasingly, users are using general purpose programming languages for further offline ana

Neural Networks, Types, and Functional Programming -- colah's blog
An Ad-Hoc Field Deep learning, despite its remarkable successes, is a young field. While models called artificial neural networks have been studied for decades, much of that work seems only tenuously connected to modern results. It’s often the case that young fields start in a very ad-hoc manner. Later, the mature field is understood very differently than it was understood by its early practitione
TensorFlow Foldについて
Googleが、TensorFlow Foldというライブラリーを発表しました。 "Announcing TensorFlow Fold: Deep Learning With Dynamic Computation Graphs" (論文は、こちら) この図の意味について簡単に説明したいと思います、 "computer scientists love "という文は、文字列あるいはwordのSepquence として見ることができます。普通のRNNやLSTMでは、こうしたSequenceとして入力を受け付けます。 ただ、先のSequenceは、文法的な構造を持っています。"computer scientists"が主語（節）で、"love"が動詞、"putting data in trees"が目的語（節）です。
シェルの弱点を補おう！"まさに"なCLIツール、egzact - Qiita
egzactというコマンドの詰め合わせセットを作ってみました。 → Github きっかけ zipで多重圧縮するのに、$ zip ファイル | zip | tee zip1 | zip | tee zip2 | zip | tee zip3 。。みたいなの出来ない？ #シェル芸 #usptomo — ぱぴろん (@papiron) 2016年3月25日 これはあるシェル芸界隈1の方の発言です。アンチウイルスソフトの動作確認で、多重ZIPされたテストウイルスファイルが必要だったとのことです。何人かの方からアドバイスを頂いていたようですが、残念ながらシェルでサクッっとは結局できなかったご様子でした2。 この事例は、シェル上でのワンライナー（a.k.a シェル芸3）の弱点の一つを如実に表しています。文字列を切り出したり、変換したりというフィルタリングの処理は得意ですが、パターン生成が比較的苦手で
The Egison Programming Language
- Express Intuition Directly with Essentially New Syntax - Egison is a programming language that features extensible efficient non-linear pattern matching with backtracking for non-free data types. We can directly represent pattern matching for a wide range of data types including lists, multisets, sets, trees, graphs, and mathematical expressions. Egison makes programming dramatically simple! --

Out of the Tar Pit | the morning paper
the morning paper a random walk through Computer Science research, by Adrian Colyer Made delightfully fast by strattic Out of the Tar Pit – Moseley & Marks 2006 This is the final Desert Island Paper choice from Jonas Bonér, and a great way to round out the week. ‘Out of the Tar Pit’ was the 10th paper that I covered in the #themorningpaper series, but at that time I was only giving highlights on t
Aggregation Module - Phase 1 - Functional Design · Issue #3300 · elastic/elasticsearch
_NOTE: at this point we're focusing more on the functional design aspect rather than performance. Once we get this nailed down, we'll see how far we can push and optimize._ Background The new aggregations module is due to elasticsearch 1.0 release, and aims to serve as the next generation replacement for the functionality we currently refer to as "faceting". Facets, currently provide a great way t
