Time Series Forecasting Using Facebook FbProphet

[@syedmunazzirahmed3191]

Hi Krish, Placing a ';' at the end of the plot statement will display only one set of plots. This is because jupyter will automatically render any matplotlib plots.

[@mahakjain2991]

It's been quite sometime now following you and I can say you are my go-to person in case if I require any detailed explanation about any of the data science topics. keep up the good work.

[@AkshayKumar-nh4fv]

It is printing twice because you are not putting semi colon there. After every plot just put semi colon

[@Learner_123]

Thank you @Krish for the wonderful tutorial. MSE, RMSE aside, would you mind guiding us on how to calculate the percentage accuracy of the model?

[@trevorcohle5138]

Hi Krish! First of all, thanks a lot for the job you are doing here! as for this video, i got a question: what is about stationarity test? do we need that one with fbprophet?

[@shilpaprusty3319]

Hi Krish , thanks for taking up this topic.Can you please create tutorial on multivariate time series and effect of exogenous variables

[@j.p.brochu8592]

I am also interested in this topic!

[@enriqueharper6270]

I know I'm kinda off topic but do anybody know of a good site to watch new tv shows online ?

[@killiansantiago7568]

@Enrique Harper i use flixzone. You can find it on google =)

[@allanzayden2200]

@Enrique Harper I use flixzone. You can find it by googling :)

[@raneshmitra8156]

Eagerly awaiting for the video.....

[@akandeifeoluwa6253]

Hi Krish, Please make a video on hourly time series prediction. I see a lot of videos on daily and monthly time series but none on hourly predictions using ARIMA or Facebook prophet.

[@spider279]

if you have seen an hourly prediction please tell me

[@patricktchuente9010]

Hi Krish, thanks for the video, but the parameters of cross validation function was not goud explained!

[@ermiasdejene]

Thanks, bruh. It was nice, simple and straight to the point tutorial. Loved it. And your presentation was clear as well as your overall flow of logic was epic. God bless you, bro.

[@kidszoneJKR]

Great Krish

[@AkashSalimath1993]

Hi Krish, I am great fan of your work, you inspired me to take up Data Analytics as my specialization in Masters. I have quick question, Can I use more than one exogenous variable in SARIMAX model? Can the SARIMAX be called as multivariate mode?

[@kevinchetti2603]

Yes, with SARIMAX, you can use multiple variables making it a multi variate time series model

[@sohinimitra7559]

Great work Krish Several time series tutorials are covering the usage of packages but very few explaining the underlying concepts and math behind them. For example, how parameters for SARIMA model can be identified using ACF/PACF plots? A detailed time series playlist will be really helpful! Nonetheless, your videos are a great resource to learn. Keep up the good work!

[@mgfg22]

how parameters for SARIMA model can be identified using ACF/PACF plots? It requires deep background, that is why you can use Auto_ARIMA to find parameters for ARIMA/SARIMA/SARIMAX!

[@alisquest]

Hi Krish....quick question do we need to fix the trend, seasonality and autocorrelation while using prophet?? Or is the model smart enough to figure those things out themselves? Thanks

[@adilmajeed8439]

It was really awesome, would it be good if you start a series of videos for geopandas which takes the individual to learn from start to finish

[@bhavinmoriya9216]

Hi Krish! Thanks for the video. How do you know seasonality is yearly? The reason I am asking is, the dataframe has daily data but you are using yearly seasonality.

[@NotFound-iu8wx]

Data is monthly with just date as the start of the month

[@chethan1914]

Hi nice video thanku, I wanted to know can use on non stationary dataset does it handel by itself or should we pump in stationary data .

[@bagavathypriya4628]

Is there any playlist for time series in your channel sir?

[@prakashchandra3454]

Can we use multiple independent features here?

[@bhuvaneshkumarsrivastava1818]

Hi Krish, one Question. Can we use it for Anomaly detection at lower grains without making a lot of False positives? (Eg: Checking for city level sales on daily basis, with total of 4000 cities)

[@shubhammittal8636]

hello krish, thanks for this information i want to know one thing what is the concept of cv and how many folds it is taking.

[@slowhanduchiha]

So sir the stock prediction in crypto will make me richer maybe lol. Such a nice video

[@DiaaHaresYusf]

date is represting the first day of month,so you cant use 365 days future_dates , please use the parameter future_dates = model.make_future_dataframe(periods = 365 , freq = 'M;)

[@pranavbhatki5744]

can somebody please explain the conept of horizon and period parameters in prophet.cross_validation ? And why's it set to 365 and 180 respectively?

[@ravibengeri1507]

Hi Sir, What approach we should follow when the target variable is following sigmoid or logistic or S curve with respect to time. Shall we still apply Time Series? If we can which algorithm we should chose as it has multiple variables affecting target variable?

[@kamrezgaming6916]

I need to full time series on pythons do you have any playlist???????

[@vishaldas6346]

Seach for ritvikmath, you'll get an entire-time series playlist.

[@abdalrazakseafaldean3789]

please brother, can you tell me how do you record the monitor. if you can make a video about how to record the monitor it will be so beneficial. thank you

[@sweetyvaidya3460]

HI Krish Can you please advise how to adjust yearly, monthly and weekly variation in one model like using 2018 thru 2020 daily data we need to project daily 2021 given by how yearly tend is going, wirh monthly seasonality ( high in winter low in summer) plus weekly seasonality ( high on Mondays low on Sunday) please help

[@shivamsharma4852]

I want one thing that data scientist can make apps. Please reply it,I really need this.❤️

[@damodharratnamthappeta2022]

you can...there is ML firebase kit from google where API's for vision,text are available and u can make apps with that

[@shivamsharma4852]

@@damodharratnamthappeta2022 so much thanks 🔥💞

[@mounabalghouthi5869]

Add a semicolon ; after `model.plot()` to prevent the graph redundancy. Issue was refrenced here: github.com/facebook/prophet/issues/396#issuecomment-354461462

[@akash_thing]

Kudos to you👍

[@leoeveee]

Data is monthly and prediction done on daily? Shouldn't it be daily data and daily prediction?

[@dvarshney]

Thanks a ton for making this video

[@deeptijoshi377]

Sir how to perform cross validation in multivariate signal data?

[@chethan1914]

Hi I am not able to install fbprophet package for python 3.7 plz help me, thanks in advance 🙂

[@9008257670]

It keeps shutting down my kernel resulting in an error message “The kernel appears to have died. It will restart automatically.”

[@9008257670]

please help

[@akshaybawal007]

same issue ! Please help!!

[@rakshitacharya630]

I got the same error it happens bacause ,if pystan doesn't install properly.

[@rakshitacharya630]

or just use google colabs

[@mohammedameen3249]

use last version of pystan and run it on anaconda

[@letsgoo5176]

output 105 its added as month - when 365 days why not change the year ? its still 1961 ?

[@joelwong7270]

Hi i know it has been 2 years since this video , but i hope i can get a reply , when we do cross validation and it states at it has done "19 forecast" , the data frame df_cv will consist of 19 forecast each consist of 365 days am i right ? but when we then apply the performance metrics function , it only gives up to 365 days of error calculated values , how does it only produce 365 days of error values when there at 19 forecast of 365 days each ? Im currently using this model and i would like to relate the performance metrics to days of the week but i do not know which time period the performance metrics function calculates... Hope i can get a response thank you, but it was a good video though

[@joelwong7270]

One more question , when i plot the " plot cross validation metric" how do i know which which horizon it is plotted from which cuttoff since so there are 19 forecast , there must be 19 cutoffs

[@dettol237]

Sir I get an error while fitting the model ,the kernel dies all of a sudden

[@ghulamjillani3811]

Hi krish plz help me how can i download fbprophet lib in my local pc plz help me i phase very errors?

[@pratiknarkhede1287]

What is mean by horizon ?

[@mlltips]

How can I forecast a number of SKUs at once ?

[@prashantsingh-bo8vu]

What’s up bro

[@abhijithjj2164]

thank you

[@rohitthorat888]

Less data than horizon after initial window. Make horizon or initial shorter. error occured

[@adithyajob8728]

thanks !

[@ajaypranavcg2971]

Prophet is a amazing module but your explanation is very confusing.

Couldn't install fbprophet. Can anyone help me

[@ananthteja]

Maybe Pystan problem. Windows 10 lo problem vasthundhi andi

[@ramyahariwan35]

@@ananthteja this might help if u are windows user , it worked for me. Try installing visual studio 2019 (if not 1 fist code line does work and try again) first you have to install c++ complier , you can install C++ complier with below command on anaconda cm 1.conda install libpython m2w64-toolchain -c msys2 once C ++ complier installed you have to install pystan, to install pystan yu can use below command 2. pip install pystan now you can install fb prophet 3.pip install fbprophet

[@pravuchaudhary3904]

why fbprophet is not installing in anaconda?

[@shilpisinha921]

What I feel is you are not clear sometimes. and you confuse a lot.

[@SC-hp5dn]

just FYI, I was following this video to download and install fbprophet for the first time but faced tons of errors and finally realized that fbprophet is now called just prophet. might help others who would struggle like I did

[@AleenDhar]

[@riddhikotak5758]

fbprophet not able to install it showing error can any one help for the same.
