This seaborn kdeplot video explains both what the kernel density estimation (KDE) is as well as how to make a kde plot within seaborn. After introducing how a KDE plot is built, I demo Python code for both the univariate and bivariate KDE plots with seaborn. I also discuss what kinds of kernel to choose and how to set bandwidth.

2:05 Univariate KDEplot code
4:02 What is bandwidth?

Great! I want to do KDE pot for a road network? Have your written this sort of code?

@KimberlyFessel 3 года назад

@@laxmanbisht2638 I haven't done KDE plots for networks, but that sounds interesting

@snelethuhashibi8254 2 года назад

Hi Kimberley, Do you know how I can label the KDE contours?

@eatbreathedatascience9593 2 года назад

Hi Kimberly, great video. Could tell me what you used to produce the slider for the bandwidth bw ? Thanks very much. !

@Tntpker 3 года назад

Arguably the most underrated video on RU-vid.

@KimberlyFessel 3 года назад

So glad you enjoyed it! This is the first public video I made for RU-vid.

@thomasdehee9626 2 года назад

Thanks you SO MUCH I bumped into this concept in a Python course and was looking for a concise explaination about KDE and was getting really anxious as anything I was finding was overly complicated You have been really clear and concise, amazing ! Suscribed

@ethanspitips5903 3 года назад

Great video on getting started with KDE plots in seaborn! Super easy to follow along, understand, and replicate the plots in a notebook. Nice job :)

@KimberlyFessel 3 года назад

Thanks much! Great to hear you could easily follow along 😄

@22niloc Год назад

Excellent - Very clear and extremely comprehensible. I"mcurrently studying DataViz with seaborn and your tutorial has just made sense of KDE.

@EvaPev 8 месяцев назад

Thank you very much for making the effort to visualise how the distributions add up. That made all the difference.

Thank you for answering in the first 30 seconds exactly what a KDE is in simple, clear terms. I was then able to understand all of the following.

@raulrubiocastillo Год назад

This helped me to better understand and apply the KDE concept to my statistical work, Kim. Thanks a lot

@jon7187 4 года назад

The de-jargon-ification of terms is reason enough to watch. The visuals and step by step walkthroughs are the reason I subscribed!

@shubhamgawali8030 3 года назад

what a Great explanation it was, I fall in love of knoweldge, subscribed channel, lot of respect from india

@shubhamgawali8030 3 года назад

I just have a one question for mpg dataset sns.histogram(cars.horsepower, kde=true) is it equal to the plot we obtained from sns.kdeplot(cars.horsepower)

@KimberlyFessel 3 года назад

Thanks very much for subscribing! And yes, you should get the same KDE plot; however, the sns.histplot(cars.horsepower, kde=True) will also give you a histogram under the KDE plot. The histplot will also likely truncate/cut the edges of your KDE plot.

@haniyehseyedalinezhad6902 Год назад

Thank you so much for this great video. Very well explained. I am just wondering how sensitive KDE is to sample size! What is the minimum number of data points required for a kernel density estimation to be considered acceptable? (My application needs KDE for univariate and bivariate cases)

@ivanrafaelvidaurrethofehrn9118 2 года назад

Hi, many thanks for the videos! You have one new subscriber for sure. I have a question, is it possible to have in one graph the histogram of the hole population of the data and the kde of one variable of the same data on the same graph?

Hi Kimberly , Nice Video very well explained, just a quick question since im new to visualization, can do we integrate these KDE plots to a folium map?

Hi Kimberly, thanks for the great video. I just subbed your channel. A quick question: Any tips on how you made possible what's going on at 4:28 and onwards? It reminds me of filtering in Tableau, but I have no idea how to do it with Python.

@leidycastro3629 2 года назад

I have the same question :/

@josephkarpinski9586 2 года назад

Great set of Python videos! An idea, if you haven’t already done it. Consider doing videos on running Python under VSCode and VSCode Insiders. Think your viewers would find it of interest. Best Regards... 👨‍💻👨‍💻👨‍💻

@saurabh3614 3 года назад

Nice explanation thanks! , how did you added a gaussian kernel for each a data point? 1:22?

@KimberlyFessel 3 года назад

Thanks! That animation is a series of individual matplotlib figures that I created basically with a for loop, adding up normal curves with standard deviation one and each point as the mean. Once I had all individual plots, I just used PowerPoint with a fade transition between each slide and recorded my screen. You can check out the code for the matplotlib figures on my GitHub page: github.com/kimfetti/Videos/blob/master/Seaborn/02_KDEplot.ipynb

@paulomur4 Год назад

When using KDE to create maps, am I creating a heatmap or a hotspot map? I think KDE is linked to heatmaps and not hotspots...is it correct? Thanks

@AnandPrakash-lb4mk 3 года назад

Nice demo Kim. Is there a way to get the equation of the generated KDE?

@KimberlyFessel 3 года назад

Thank you! And not that I know of. It appears that seaborn (like many other Python techniques I've seen) will produce numerical values for the KDE but not the full equation.
