How did I pass in 4 google certifications in one month?
This past month I took the google associated, professional, architect, and machine learning engineer certifications, this post will be about some tips I can share with you guys.
First I gotta say there is no magic or shortcut, you actually need to study a lot!!!
But I have a few tips that can help you… so let’s start!
1- Don’t skip steps, make the associated, professional, and then the architect. The answers are not the same of course, but the style remains the same, so it’s best to start…
The data field is relatively new, and I still feel that a lot of people that are trying to break into the field have a lot of doubts about what each role does exactly.
So to explain what a machine learning engineering does I’ll need to explain the other two most common roles of data science.
First let’s start with the data engineering, I see a lot of companies wanting to hire data scientist but what they actually need is a data engineering. They are responsible for structuring where and how the data will be stored. …
Data Fusion is a google cloud solution for building data pipelines without any code, although the solution has some limitations (so far) when used together with Cloud Composer becomes a really powerfull tool to build data lakes.
So for me the biggest limitation that I found with Data Fusion is that you cannot pass dinamic parameters, the only dinamic parameter that it accepts are with dates that works with the formula bellow:
This will return the current date, if you want something like yesterday you can obtain like this:
But except from that, you cannot pass dinamic parameters…
If you are in the Data world, the sentence you gonna hear the most is always, 90% is data and 10% is model, but when you starting looking at tutorials on the internet 99% are about models, I’ve seen several data scientist that known how to make a great model and were total noobies when they need to check if there was missing values on the columns, so this post will be about the most important part of data, the data.
1- When exploring a new dataset, the first thing you should do is to check if the inputs…
I know that for the most experienced data scientists this question is all old as data science itself, but for beginners this is a real issue, so let’s begin the fight! 👊
In the beginning when there was no data science as we know today, statisticians started using R for their analysis, so in earlier 2000s when the computers started to be strong enough and the big datasets were being created it was only natural that R was the default language for Data. …
It’s normal at the beginning of the Data Science journey you start studying some real basic stuff like housing price trends, and then you study a little bit of time series and after that you go straight into computer vision and some other really hard stuff.
So far as a Data Analyst I have never faced a problem in the workplace that I used computer vision to solve it, but every week there is always a Time Series problem.
So let’s make a deep dive here into time series:
The life of all data beginners
First of all, this…
So if you are going to take the Tensorflow certificate exam, the first thing you gotta do is to prepare the enviroment as said in the handbook, believe or not I lost quite some time doing this especially because I wasn’t used to use Pycharm -anaconda for life-.
Here is some tips to prepare:
First things first, you need to update the pip install to the lastest version, you can do this on this arrow:
file -> settings ->project -> interpreter:
Em visão computacional o grande desafio é encontrar grandes datasets com imagens corretamente identificadas, já houve algumas tentativas de usar imagens criadas digitalmente:
Neste post irei focar no código que é usado para criar uma ConvNet, caso sobre queria saber mais detalhes sobre o assunto, recomendo irem no post 1 e post 2 onde eu explico os conceitos do que está sendo feito aqui.
Para realizar esse exemplo, eu peguei uma competição do Kaggle chamada de Dovs vs Cats. O objetivo do desafio era bem simples, eles forneciam 10k fotos de cachorros e gatos, e deveríamos contruir um modelo que identificasse se na foto era um cachorro ou gato.
Primeiramente vamos importar os pacotes que vamos necessitar para esse projeto:
import matplotlib.pyplot as…
Essa semana concluí uma especialização em visão computacional e reparei que grande parte dos conteúdos que estudei eram em inglês. Há um gap muito grande de conteúdos em nosso idioma e para tentar ajudar nessa produção de conteúdo nacional, vou contar sobre o meu aprendizado neste curso feito pela deeplearning.ai.
Então começando, o que é visão computacional?
Enxergar o mundo para nós humanos é algo natural, quando nascemos abrimos os olhos e…
