Introduction

Since it’s first 1.x release, Spark became the de facto Big Data unified processing Engine. 9 of 10 companies chose Spark for their Data processing thanks to its speed, ease of use, modularity and extensibility. The aim of this series of articles is to:

  • Introduce you to the evolution of Big Data and how Spark came to existence.
  • Provide a high-level overview of all the components of Spark’s distributed architecture.
  • Provide best practices regarding Spark jobs code optimization.
  • Provide best practices for tuning, debugging and inspecting Spark applications

We assume that you are already familiar with Spark Structured High Level…


La crise du Coronavirus a été pour nous tous une expérience inédite qui va laisser des traces à jamais. Pendant deux mois, nous avons renoncé à ce qu’il y a de plus fondamental dans notre mode de vie : Notre liberté de circulation. Nous y avons renoncé et nous nous sommes confinés chez nous, malgré nous. Plus de sorties entre amis. Plus de réunions familiales. Plus de balades. Plus de soirées. Plus de cafés ou de restos. Plus de vacances.

Heureusement pour nous, le virus disparait progressivement. Ses mutations le rendent de moins en moins dangereux. Le nombre de nouveaux…


I am currently Taking Deeplearning.ai Deep Learning Specialization which I highly recommend by the way for people who are looking for a great place to start deep learning. The Specialization is offered on Coursera and I have just finished their third Course : Structuring Machine Learning Projects.

The course explains how to be systematic when it come to thinking about Deep Learning projects and gives you an array of tools that’ll help you to make the right decisions and move forward with your machine learning project.

Most of the ideas of this course are not included in university deep learning…


Introduction

In this tutorial, you will learn how to build your own Meme Detector from scratch like this one. By the end of the tutorial, you will be able to:

  • Create your own dataset using Google Image.
  • Choose and retrain the dense layers of a CNN architecture.
  • Deploy your model as a web app to Render.com

Libraries and major dependencies

  1. Google Colab for GPU usage
  2. Fastai v 1.0.52
  3. PyTorch v1

Fastai is an amazing library built on top of PyTorch to make deep learning more intuitive and make it require less lines of code. …


Introduction

I’m currently taking fast.ai’s deep learning course. To apply the concepts I learned in the first lesson, I used a really small dataset created during a Machine Learning Lab at ENSEEIHT to do image classification.

The dataset consists of 264 photos of hands doing “Paper”, “Rock” and “Scissors” gestures as follows :

The photos have been taken using a smartphone. It involved a group of 9 students (I was part of the dataset creation process) pursuing the ENSEEIHT (Toulouse) MS in Data Science. …


Disclaimer: I am new to machine learning and also to blogging (First). So, if there are any mistakes, please do let me know. All feedback appreciated.

If you go to google and type “Best online Machine Learning classes”, chances are, Andrew Ng’s Machine Learning class offered at Coursera will be on top for most of the rankings out on the Internet. With more than 2.5 …
