#NetUniversity – Introducción a Machine Learning (Curso Online)

Buenas!

Existen muchos recursos para comenzar a aprender Machine Learning. Sin embargo, suele ser complicado elegir uno que realmente se adapte a nuestro perfil, y que nos permita aprender de forma coherente y concisa los principios de Machine Learning. Si trabajas con tecnologías Microsoft o eres un programador .Net, este curso es para ti.

Durante este curso veremos los conceptos principales que explican el estado actual de Machine Learning; y aprenderemos utilizando ML.NET (Machine Learning.Net ). ML.Net es un conjunto de herramientas que ha alcanzado de forma oficial su versión Release y que será la base del aprendizaje de Machine Learning. Veremos escenarios para aprendizaje supervisado y no supervisado, escenarios de análisis de sentimientos de texto, escenarios de integración con otras tecnologías de ML, como ONNX o TensorFlow, y mucho más.

Introducción a Machine Learning

Cuando termines el curso, estoy 100% convencido que podrás aplicar estos conocimientos para encontrar los mejores escenarios de ML en tus investigaciones o tu trabajo del día a día.

Y por cierto, tengo algunos cupones de descuento, si los quieres contáctame! Y puedes revisar algunos de mis posts de Machine Learning.Net aquí.

#Podcast – Talking about #Azure Notebooks with Rodrigo (@rdiazconcha) in Interfaz (spanish podcast)

Hi!

As it turns out that I have been fortunate to participate, once again, in Interface: the podcast that my friend Rodrigo Diaz Concha manages and coordinates (link). This time, I’ve talked about one of the coolest preview products we have in Azure: Azure Notebooks.

This product sounds weird for a .Net Developers, however, the power, productivity, and collaboration capabilities that Jupyter notebooks provide are something the Python community has long taken advantage of.

I’d better leave the podcast link and hope you enjoy it (remember, is in Spanish):

Este producto suena raro para un .Net Developers, sin embargo, la potencia, productividad y capacidades de colaboración que proveen las Jupyter notebooks, son algo que la comunidad de Python aprovecha desde hace tiempo.

#Personal – Amazing surprises managing the internet traffic at home #RaspberryPi #PiHole #Windows10

Hi !

A couple of days ago, my friend Luca (@lucavgobbi) told me about PiHole: A Network-wide Ad Blocking. Even better, let me copy the official description from their GitHub repo:

The Pi-hole® is a DNS sinkhole that protects your devices from unwanted content, without installing any client-side software.

Easy-to-install: our versatile installer walks you through the process, and takes less than ten minutes

Resolute: content is blocked in non-browser locations, such as ad-laden mobile apps and smart TVs

Responsive: seamlessly speeds up the feel of everyday browsing by caching DNS queries

Lightweight: runs smoothly with minimal hardware and software requirements

Robust: a command line interface that is quality assured for interoperability

Insightful: a beautiful responsive Web Interface dashboard to view and control your Pi-hole

Versatile: can optionally function as a DHCP server, ensuring all your devices are protected automatically

Scalable: capable of handling hundreds of millions of queries when installed on server-grade hardware

Modern: blocks ads over both IPv4 and IPv6

Free: open source software which helps ensure you are the sole person in control of your privacy

I setup this in an extra Raspberry Pi 3 that I have at home, and keep it running for the last couple of days. I was in shock when I realized that aprox 30% of my internet traffic is … not so good.

PiHole dashboard

One of the cool features of PiHole, os that you can work with their logs. So I decided to apply some very powerful Machine Learning algorithms to detects anomalies and strange behaviors.

In the meantime, I decided to read the logs, and make some filters just using Excel. And I found a lot of very strange urls. Today I’ll share some of the Microsoft ones.

So, in example, do you know what does this set of urls have in common?

  • location-inference-westus.cloudapp.net
  • licensing.mp.microsoft.com
  • watson.telemetry.microsoft.com

They are all Microsoft endpoints ! It seems that Windows 10 is sending a lot of diagnostic and other type of data. Lucky for us, most of this endpoints are well explained for each one of the Windows 10 versions. So, in example, I don’t use a lot of UWP apps, and it seems to me that the localization service does not need to send a lot of information, from a FIXED PC.

I decided to add some of this domains to the blacklist of domains and so far, so good. Windows is still working amazing, I enabled some of the urls so I can use also Visual Studio and Azure DevOps, and my user experience is still the same (with 30% less of traffic!)

So, I may want to also write about some domains I found other chatty devices uses like my Amazon Alexa, my Roku, and more … maybe in the next post! And kudos to the PiHole team!

Happy Coding!

#VSCode – Let’s do some #FaceRecognition with 20 lines in #Python (6/N)

Hi !

I’ll start with my posts

  1. Detecting Faces with 20 lines in Python
  2. Face Recognition with 20 lines in Python
  3. Detecting Facial Features with 20 lines in Python
  4. Facial Features and Face Recognition with 20 lines in Python
  5. Performance improvements with code

In my last post I share some lines of code which allowed me to run some of the face recognition demos 6 times faster. I added a Frames per Second (FPS) feature in my samples. Later, thinking about performance, I realize that I don’t need to work with a full HD picture (1920 x 1080), so I added some code to resize the photo before the face detection process.

However, while I was coding arond this solution I also realized that I may want to initialize my camera to start in a lower resolution. So, I searched online on how to do this with OpenCV and I found 3 beautiful lines of code.

open camera with opencv with lower resolution

So, I manage to improve my processing code from 20FPS to +30FPS … which is very good ! Later on this posts I’ll try to do some similar FPS tests on a smaller device and I’ll see and share how this works.

Happy Coding!

#RaspberryPi – The amazing single command to install UI mods in #Raspbian Lite (yes, my memory need this …)

Installing Packages in Raspberry Pi lite!

Hi !

Quick post today. And a memory backup one. I just spend 30 minutes trying to install a desktop UI in a clean lite RaspberryPi install. And I missed and missed again the command.

The right command is

sudo apt install raspberrypi-ui-mods

And that’s it. Now is here, so I can search me and find the solution.

Context: I use the [Raspbian Buster Lite] distro for the Raspberry Pi. In 10 minutes I got the SSH enabled so I can perform most of my operations remotely from my computer.

Download Raspbian https://www.raspberrypi.org/downloads/raspbian/

Did you check the news?

  • 64-bit Quad-Core ARM Cortex-A72 processor, with a core clock speed of 1.5GHz
  • 1GB, 2GB or 4GB of RAM
  • 2 4K HDMI displays
  • USB 3
  • Bluetooth 5
  • starting price at $35
  • and much more !

I won’t get deep in details, I prefer to share some really good reviews, later i this post. Now is time to wait until the 4GB model is available in Canada and I’ll do some update on my Custom Vision docker and Machine Learning performance posts with the new device!

Detailed review!

Happy Coding!
