https://github.com/google/brotli/

Brotli is a generic-purpose lossless compression algorithm that compresses data using a combination of a modern variant of the LZ77 algorithm, Huffman coding and 2nd order context modeling, with a compression ratio comparable to the best currently available general-purpose compression methods. It is similar in speed with deflate but offers more dense compression.

GitHub - google/zopfli: Zopfli Compression Algorithm is a compression library programmed in C to perform very good, but slow, deflate or zlib compression.

While Zopfli is Deflate-compatible, Brotli is a whole new data format. This new format allows us to get 20–26% higher compression ratios over Zopfli.

FST というのは Finite State Transducer (有限状態変換機) の略で，有限オートマトンに出力がついたものです．変換機とか言うと小難しい感じがするかもしれませんが，文字列を入力として，文字列を返す単純な機構です．（機能としては map[string]string みたいなものです)．

cedar - C++ implementation of efficiently-updatable double-array trie

http://www.tkl.iis.u-tokyo.ac.jp/~ynaga/cedar/

Cedar implements an updatable double-array trie [1,2,3], which offers fast update/lookup for skewed queries in real-world data, e.g., counting words in text or mining conjunctive features in a classifier.

Computational Network Toolkit (CNTK) - Home

https://cntk.codeplex.com/

CNTK, the Computational Network Toolkit by Microsoft Research, is a unified deep-learning toolkit

CNTK allows to easily realize and combine popular model types such as feed-forward DNNs, convolutional nets (CNNs), and recurrent networks (RNNs/LSTMs). It implements stochastic gradient descent (SGD, error backpropagation) learning with automatic differentiation and parallelization across multiple GPUs and servers.

[1506.03340] Teaching Machines to Read and Comprehend

http://arxiv.org/abs/1506.03340

In this work we define a new methodology that resolves this bottleneck and provides large scale supervised reading comprehension data.

The Impatient Reader
The Attentive Reader is able to focus on the passages of a context document that are most likely to inform the answer to the query. We can go further by equipping the model with the ability to reread from the document as each query token is read.

NTCIR-12 Task on Short Text Conversation

http://ntcir12.noahlab.com.hk/japanese/stc-jpn.htm

Dataset of Japanese task

The input data will be those randomly sampled from tweets in the year 2015. The pool of tweets (the target for extraction) is the randomly sampled tweet pairs (mention-reply pairs) in the year 2014. The size of the pool is just over one million; that is 500K pairs.

The following data will be provided from the organizers:
(1) Twitter data (by using their IDs) 1M in size
(2) Development data. Input samples and output samples annotated with reference labels. Here, the number of annotators is ten.

Conclusion

Summary
* supervised machine reading is a viable research direction with the available data,
* LSTM based recurrent networks constantly surprise with their ability to encode dependencies in sequences,
* attention is a very effective and exible modelling technique.

Future directions
* more and better data, corpus querying, and cross document queries,
* recurrent networks incorporating long term and working memory are well suited to NLU task.

Marvin: Deep Learning in N Dimensions

http://marvin.is/

Marvin was born to be hacked, relying on few dependencies and basic C++. All code lives in two files (marvin.hpp and marvin.cu) and all numbers take up two bytes (FP16).

Marvin’s life depends on an NVIDIA GPU with CUDA 7.5 and cuDNN 3.

https://github.com/PrincetonVision/marvin/

Marvin is a GPU-only neural network framework made with simplicity, hackability, speed, memory consumption, and high dimensional data in mind.
