Tensorflow conditionals and while loops

   |  5 minutes  |  897 words  |  Milos Gajdos

Tensorflow conditionals and while loops Recntly I found myself needing to implement more advanced control flow in some models I have been hacking on in my free time. In past I never really needed any graph conditionals or loops or any combinations thereof, so I had to dive into documentation and read up on them. This blog post covers tf.cond and tf.while_loop control flow operations and was written to document and share my experience learning about them. [Read More]

Hopfield networks in Go

   |  12 minutes  |  2465 words  |  Milos Gajdos

As I continue to explore the realm of Artificial Neural Networks (ANN) I keep learning about some really cool types of neural networks which don’t get much attention these days. Many of these networks have not found much practical use in the “real world” for various reasons. Nevertheless, I find learning about them in my free time somewhat stimulating as they often make me think of some problems from a different perspective. [Read More]

Kubernetes services and ingress under X-ray

   |  20 minutes  |  4256 words  |  Milos Gajdos

I haven’t blogged here for over 2 years. It’s not that I had nothing to say, but every time I started writing a new post I never pushed myself into finishing it. So, most of the drafts ended up rotting in my private Github gists. Although my interests have expanded way beyond the Linux container space, my professional life remained tied to it. Over the past two years I have been quite heavily involved in Kubernetes (K8s) community. [Read More]

Self-organizing Maps in Go

   |  17 minutes  |  3413 words  |  Milos Gajdos

Couple of months ago I came across a type of Artificial Neural Network I knew very little about: Self-organizing map (SOM). I vaguely remembered the term from my university studies. We scratched upon it when we were learning about data clustering algorithms. So when I re-discovered it again, my knowledge of it was very basic, almost non-existent. It felt like a great opportunity to learn something new and interesting, so I rolled up my sleeves, dived into reading and hacking. [Read More]

Fun with neural networks in Go

   |  28 minutes  |  5893 words  |  Milos Gajdos

My rekindled interest in Machine Learning turned my attention to Neural Networks or more precisely Artificial Neural Networks (ANN). I started tinkering with ANN by building simple prototypes in R. However, my basic knowledge of the topic only got me so far. I struggled to understand why certain parameters work better than others. I wanted to understand the inner workings of ANN learning better. So I built a long list of questions and started looking for answers. [Read More]

Principal Component Analysis - Part 2

   |  12 minutes  |  2480 words  |  Milos Gajdos

This is the second post of the series about Principal Component Analysis (PCA). Whilst the first post provided a theoretical background, this post will discuss the actual implementation of the PCA algorithm and its results when applied to some example data. Theory Recap In the first post we learnt that PCA looks for a vector basis that can express the analysed data in a better (less redundant) way, whilst retaining as much information from the original data as possible.

Principal Component Analysis - Part 1

   |  13 minutes  |  2655 words  |  Milos Gajdos

This is the first of the two post series about Principal Component Analysis (PCA). This post lays down important knowledge bricks that are needed to understand the core principles of the PCA algorithm. The second post will discuss the actual implementation and its results by applying it to various data sets. Motivation The world is becoming more data driven than ever before. We collect large amounts of data from arbitrary sources. [Read More]

Docker vs Rocket gimme a break

   |  11 minutes  |  2319 words  |  Milos Gajdos

Alert! This is another rant blog post! I promise the next one will be more technical :-) Rocket launch me some opinions Past few days I’ve been playing around with Rocket, the new container runtime by CoreOS. Quite a few people have asked for my opinion so I figured I would put it into a blog post. I haven’t planned on publishing it any time soon, but few blog posts I have come across recently have prompted me to put off the original post and write a different one first. [Read More]

Future of Docker networking

   |  8 minutes  |  1607 words  |  Milos Gajdos

Disclaimer: I do not work for Docker nor for any company whose business is tied to Docker in any way Recently there has been a lot of discussions about the future of Docker networking in various communication channels. It is due to hugely increased Docker usage over the past year. Users are now realising Docker’s networking limitations which are becoming more apparent. The truth is, and I’m sure we can all agree on this, the current networking capabilities of Docker are not sufficient for more complicated setups. [Read More]

Tenus Golang Powered Linux Networking

   |  22 minutes  |  4515 words  |  Milos Gajdos

2014-07-30 22:35 Update: I’ve updated the post with the link to netlink RFC. I’ve also replaced references to golang with Go programming language on majority of mentions in the article. I do agree with the people in discussions on the topic of Go/golang, but I’ve adpoted golang in my vocabulary as that’s my standard search term on Google for the information about Go language, hence the abundance of the word golang in the original post.
