Plotly is a data visualization tool that is good for data journalists and bloggers. It allows creation of web figures, shows exact values, allows data sharing, and streaming of data. The Plotly Julia API allows access to Plotly's functionality from the Julia programming language. Some example visualizations created with Plotly include network diagrams, tax rates vs income levels, healthcare spending vs life expectancy, and a chocolate bar chart. Plotly has a Facebook group and Mashup Award for visualizations created with the tool.
Juliaで学ぶ Hamiltonian Monte Carlo (NUTS 入り)Kenta Sato
Hamiltonian Monte Carlo (HMC) is an MCMC method that uses Hamiltonian dynamics to efficiently explore the target distribution. It simulates the trajectory of a particle under Hamiltonian mechanics to propose new states that are usually accepted. No-U-Turn Sampler (NUTS) improves on HMC by automatically tuning the integration time.

1. The document discusses metrics for measuring the value of customer data, including P(D)*D*CV which represents the probability of a customer, multiplied by the number of customers and customer lifetime value.
2. It also mentions a metric called BTB (back to base) which measures the percentage of customers who return to a website or app within a set time period, such as 5% returning within a day or 100% returning within a year.
3. Finally, it discusses concepts like single customer view, deep packet inspection, key performance indicators, and the idea of turning analysis into action through techniques like A/B testing and CRM integration.
These are slides from the Dec 17 SF Bay Area Julia Users meeting [1]. Ehsan Totoni presented the ParallelAccelerator Julia package, a compiler that performs aggressive analysis and optimization on top of the Julia compiler. Ehsan is a Research Scientist at Intel Labs working on the High Performance Scripting project.

This document contains R code for exploring various R functions and packages. It downloads an R script from GitHub, loads packages from CRAN and Bioconductor, explores basic functions like plotting, looping, and object manipulation, and creates an R package skeleton. The code covers many fundamental and advanced R topics.

Daichi Kitamura, "Generative model in nonnegative matrix factorization and its application to multichannel sound source separation," Keio University, Science and Technology, Department of Electronics and Electrical Engineeing, Yukawa Laboratory, Invited Talk, Kanagawa, November, 2015.
This document discusses benchmarking deep learning frameworks like Chainer. It begins by defining benchmarks and their importance for framework developers and users. It then examines examples like convnet-benchmarks, which objectively compares frameworks on metrics like elapsed time. It discusses challenges in accurately measuring elapsed time for neural network functions, particularly those with both Python and GPU components. Finally, it introduces potential solutions like Chainer's Timer class and mentions the DeepMark benchmarks for broader comparisons.
The document summarizes a meetup discussing deep learning and Docker. It covered Yuta Kashino introducing BakFoo and his background in astrophysics and Python. The meetup discussed recent advances in AI like AlphaGo, generative adversarial networks, and neural style transfer. It provided an overview of Chainer and arXiv papers. The meetup demonstrated Chainer 1.3, NVIDIA drivers, and Docker for deep learning. It showed running a TensorFlow tutorial using nvidia-docker and provided Dockerfile examples and links to resources.
