11:35 AM | Non-linear Causal Inference using Gaussianity Measures - implementation -
Rewatching Leon Bottou's talk yesterday, I was reminded of David Lopez-Paz's paper on the subject that I had not mentioned before. I wonder if this work could not be helped with some of the tool developed in advanced matrix/tensor factorization:Non-linear Causal Inference using Gaussianity Measures by Daniel Hernandez-Lobato, Pablo Morales Mombiela, David Lopez-Paz and Alberto SuarezIn this paper we provide theoretical and empirical evidence of a type of asymmetry between causes and effects […]

10:57 AM | Blue Bonnet Bayes
Blue Bonnet™ used to run commercials with the jingle “Everything’s better with Blue Bonnet on it.” Maybe they still do. Perhaps in reaction to knee-jerk antipathy toward Bayesian methods, some statisticians have adopted knee-jerk enthusiasm for Bayesian methods. Everything’s better with Bayesian analysis on it. Bayes makes it better, like a little dab of margarine […]

7:46 PM | Welcome, Attorneys!
You might wonder why I am welcoming attorneys to the blog.  Well, I happen to know that some attorneys read my blog.  I know this because recently, as an expert witness, while I was testifying in court, the attorney on the other side during my cross-examination specifically asked me about my blog.  Based on their questions, I am reasonably sure they had downloaded all the posts.  I imagine some poor associate attorney low on the totem pole had to read through it all to see […]

7:32 PM | Everything You Should Know About Android 5.0 Lollipop
Google took the unprecedented step of offering an early developer preview of Android L (now Android 5.0 Lollipop) last spring. We knew this version of Android was going to be a big shift, something for which developers would need to plan. However, it wasn't until the recent official announcement that it became clear how massive this change would be. Android 5.0 is a break from the past, and in many ways a complete reinvention of the platform.Here's what you need to know about Android 5.0, the […]

7:10 PM | All in for AcWriMo 2014
November is just around the corner, which means once again it’s time for AcWriMo! For those who don’t know, AcWriMo is the academic’s version of NaNoWriMo (in which people pledge to write a novel during the month of November). The academic version is a bit more fluid—participants set their own academic writing goals for the month, […]

6:00 PM | In Brief: Amazon Announces Fire TV Streaming HDMI Stick
Amazon today announced the Fire TV Stick, an HDMI streaming stick with the capability of Amazon's $100 Fire TV set-top box. The $40 stick is positioned against Google's Chromecast and Roku's Streaming Stick, and Amazon is boasting its technical specs. It runs off of a dual-core Broadcom A9-based SoC, has 1GB of RAM, and 8GB of internal flash storage--higher than Google and Roku's options. Dual-antenna MIMO Wi-Fi may also give it a leg up in homes with spotty wireless connections. Of course, […]

5:00 AM | BRTF: Robust Bayesian Tensor Factorization for Incomplete Multiway Data - implementation -
Here is an extension of Robust PCA to tensors:Robust Bayesian Tensor Factorization for Incomplete Multiway Data by Qibin Zhao, Guoxu Zhou, Liqing Zhang, Andrzej Cichocki, Shun-ichi Amari We propose a generative model for robust tensor factorization in the presence of both missing data and outliers. The objective is to explicitly infer the underlying low-CP-rank tensor capturing the global information and a sparse tensor capturing the local information (also considered as outliers), thus […]

1:09 AM | How well does sample range estimate range?
I’ve been doing some work with Focused Objective lately, and today the following question came up in our discussion. If you’re sampling from a uniform distribution, how many samples do you need before your sample range has an even chance of covering 90% of the population range? This is a variation on a problem I’ve […]

10:15 AM | SparsePR: Robust Sparse Phase Retrieval Made Easy - implementation -
Robust Sparse Phase Retrieval Made Easy by Mark Iwen, Aditya Viswanathan, Yang Wang In this short note we propose a simple two-stage sparse phase retrieval strategy that uses a near-optimal number of measurements, and is both computationally efficient and robust to measurement noise. In addition, the proposed strategy is fairly general, allowing for a large number of new measurement constructions and recovery algorithms to be designed with minimal effort.  The implementation of SparsePR […]

Over at democracy corner, Manchester Digital is interviewing all of its elected council members. Somehow, I got volunteered to be first interviewee. Here’s my two pence on one of the questions asked: “What do you think is biggest challenge we face as an industry?” (with some extra links) Firstly, coding and “computational thinking” [1], needs to be understood as something that isn’t […]

As part of the celebrations commemorating the 50th anniversary of French-Chinese diplomatic relations, a French theatrical production company brought two giant mechanical puppets to Beijing's Bird Nest stadium for three days of performances. The company, La Machine, is known for the 50-foot tall mechanical spider--named La Princesse--that it built and brought to Liverpool in 2008 as part of that city's Capital of Culture festival. Weighing almost 40 tons, La Princesse is operated by a team of […]

12:40 PM | Adaptive Compressed Sensing for Estimation of Structured Sparse Sets
Rui just sent me the following:  Hi Igor, Not sure if this is the appropriate way to do it, but I wanted to (shamelessly) point you (and the readers of nuit blanche) to our recent work on adaptive compressive sensing for structured sparsity:http://arxiv.org/abs/1410.4593 In this work we investigate the problem of estimating the support of structured signals via adaptive compressive sensing. We examine several classes of structured support sets, and characterize the signal strength […]
