Hi Data Science enthusiasts πŸ‘‹
.
Today, we are gonna talk about broadcasting in NumPy πŸ”’
.
Broadcasting is a powerful, useful yet tricky feature in NumPy. If you know it well and use it intentionally, you can simplify a lot of code πŸ‘Œ
.
However, if it’s used by mistake it can create bugs and a lot of headaches πŸ€•
.
That’s because in NumPy, you can easily do operations between matrices even if they don’t have the same shape πŸ‘Œ
.
NumPy β€œbroadcasts” the smaller matrix (if valid for the operation) and repeats the operation per element, row, column, etc 🀘
.
In today’s code snippet, a scalar broadcasts into the same size of a matrix to be subtracted. Similarly, a row and column vector broadcasts into the right shape before getting subtracted!

Partitioning is an important technique when you have a large amount of data and like to partition it based on a pivot value. NumPy can do this very efficiently and it leads to some cool applications.

Hi everyone πŸ‘‹πŸ‘‹.I wanted to introduce Pandas to you in case it’s new to you. We will be working a lot with it in the future so a nice introduction will go a long way πŸ™Œ.I have asked a few of my friends ‼️ to help me introduce Pandas to you by showing up on the post πŸ˜‚πŸ˜‚.Jokes aside, Pandas is a really powerful data analytics library in Python that I use almost everyday. It’s robust, fast, and great for prototyping data science problems 🧠..It quickly feels like you’re working with a database, so if you know SQL this won’t feel too different..Let me know who your favorite founder is from the 4 on the picture. I’ll keep mine a secret for now. πŸ‘

Hi everyone πŸ‘‹πŸ‘‹.My friends are here again for part 2 of our intro to PandasπŸ‘ŒπŸŽ‰πŸ‘.In Pandas, you can easily extract more useful data points from existing data in the table, and because Pandas has been optimized to work on large amounts of data, column operations are super fast πŸ’¨..Here I divide the founders’ net worth by their age, to get a sense of their average wealth accumulation rate.Then I am interested to see who’s accumulated wealth the fastest, so I sort the column in the descending order πŸ™ŒπŸ».Super fast, in a few lines, I have answered a couple of my questions about my favorite founders πŸ‘.

Hello all and welcome to the 3rd episode of our Intro to Pandas series @bigdataguru πŸ‘‹πŸ™.Our friends, the 4 founders, have been kind enough to show up once again to help us understand two important functions on Pandas πŸŽ‰.groupby()mean().Groupby() as the name suggests groups the rows of data frame based on the values of a column of columns..The result of the groupby is usually used for aggregation of data, in the case finding the mean number of employees employed in given states by these 4 companies.With those in our toolset, we can now do incredible things with data πŸ™ŒπŸ»πŸ™ŒπŸ».

Hi data scientists πŸ‘‹πŸ‘‹πŸ‘‹.A coincidence that the day we just finished was Valentine’s Day but I have been receiving a lot of love πŸ’™ from you guys lately! Many of you have reached out and supported the content, just know that it’s appreciated and it will make this page better! πŸ‘Œ.With that, let’s get to today’s post, shall we?? .Of course when we are talking about Pandas, our good friends the founders are back to help us! πŸŽ‰.However our founders have been having a little argument lately. Even one was allegedly heard calling another one β€œhey boomer” ‼️ and the other responded back with β€œyou millennial” πŸ€¦πŸ»β€β™‚οΈ Even though arguments are not nice, this gives us the chance to use Pandas to settle who is in what generation!.pd.cut allows us to categorize a continuous spectrum into bins πŸ‘Œ here our bins are the generations and the continuous spectrum is the year number πŸ‘.After seeing exactly who’s in what generation, our founders realize that they should apologize to each other. They have promised to treat each other better in the next post so stay tuned πŸ—£.Correction: founders_df[β€œBirth”] should be founders_df[β€œBirthYear”] ‼️‼️

Hello all and welcome to the post of the day πŸ™ .Today, we are going to introduce Machine Learning and Deep Learning and talk about what makes them different πŸ€” .In traditional machine learning, scientists had to define concrete and well defined features for the inputs, those features would then get fed into a neural network that would produce a prediction πŸ‘.In deep learning however, we are leaving it to the network to learn and ultimately decide which features it seems relevant to the learning problem πŸ’‘ .This is precisely why deep learning is so powerful, everything end to end is learned by the network. The hard part then becomes designing the perfect network for a given problem 🧠.Super excited to be going through this journey through AI with you guys. Stay tuned for more machine learning posts this coming week πŸŽ‰
