It is a very snowy day in the Twin Cities of Minneapolis and St. Paul. Schools are closed due to the amount of snow and low visibility. It started snowing earlier this morning and according to forecast, it should end around 09:00 PM this evening. We have already surpassed the snow amount for February according to records that go back over a century. We will be receiving more snow in the upcoming days. Will see if we set other new records.
In this post I will cover a logistic regression implementation used to determine if pictures contain a cat or not. The code is based on an edited assignment for Coursera Neural Networks and Deep Learning. Continue reading “Logistic Regression with a Neural Network mindset”
Towards the end of last year I started taking the Coursera course “Neural Networks and Deep Learning” taught by Andrew Ng. In a nutshell the course was great. I highly recommend it. That said; I ran into an issue with time. Allow me to explain and how I am addressing it. When done reviewing, will take the next course in the series.

It is getting late in the day for me. I am a believer in deep work so several months ago I decided to get up early morning and study for a couple hours. So far, it has worked very well for me. I have set a wakeup alarm for 05:00 AM 7-days a week. Typically I am awake between 04:30 and 05:00 so I just turn off the alarm and head down to my home office. Around 05:00 PM I feel the work day coming to an end and am ready to punt. I use EyeDefender to break every two hours. During my 5 to 10 minute breaks I walk and get some fresh water. What can I say; it works for me. On weekends I tend to just do two are three blocks. On work days I tend to do five. Continue reading “ACM and Coursera”
I am constantly reading and experimenting to learn things which I may apply to work projects. A few years ago I decided to spent time on and off learning machine learning (ML). With that purpose in mind, I got a number of books on different subjects (e.g., Deep Learning, Python and Statistics) which seemed to be useful to achieve my goal.
On the platform side, I started experimenting on Windows. Most things work fine but some things do not. For example, I had to wait to use Tensorflow because it ran on Linux but not on Windows. Today it seems to work on both. The same seems to hold true for Docker. Continue reading “Machine Learning – Setup”
I have been busy traveling and spending time with family and friends so I have not posted in a couple weeks. Sorry about that. Today is January 01, 2018, so Happy New Year. It is and for the past several days has been quite cold in this part of the country. Today we woke up to a fresh -13F. My wife and I will go to the Mall of America in an hour or so to get some steps on our Fitbits.In the past decade or so there has been a huge interest in artificial intelligence. It seems that, different aspects of AI have been creeping into applications in multiple domains (i.e., Biology, Business, Computer Science, Computer Vision, Economy, and many others).

I received a message from HackerRank suggesting the BotClean challenge. If interested take a look at the requirements at the following URL: https://www.hackerrank.com/challenges/botclean
I had an issue with the Output Format description. Some time ago I looked at a different challenge and my solution generated a set of steps in order to complete each task. In this case only one step may be displayed at a time. Seems that the code that invokes the method next_move() updates the coordinates and the board each time after executing a move.
