In this video I show how you can use facebook's prophet model to easily do time series forecasting in python. This model is very powerful because it uses an additive model where non-linear trends are fit with yearly, weekly, and daily seasonality, plus holiday effects.

The best thing about machine learning is this... Once you've built your models, you can just train them on different data. I have a single notebook which loads in my data and then the rest of the notebook contains all the models I have learned along with their cross validation and evaluation metrics. I can just change the data and run the entire notebook and then check on it occasionally to see the results. It can take an hour or two to build each model but once you have them all built, you're good to go and you can just add to the notebook as you learn more. You may even want to split your models into separate notebooks but i prefer to run them all in one as i then only need to alter the data in that one.

Hello Rob, great video, thanks for sharing! This was my introduction to the Prophet model, and loved your explanation, crystal clear sa always! I have a quick question though: if I understand correctly, Prophet should work as a regression model given this very problem, and hence we could calculate R2 as well as metric along with RSE, MAE and MAPE. Is it recommendable to do it, or it makes no sense for this particular model? What's your take? Thanks a lot!

Hey Rob, Awesome Video. I think you need to take note that if you try to run your kagle notebook with a different data set, it's impossible to evaluate the error metrics because the y_pred array is the same size as the data set. I had to write a few more lines to extract just the last x values I needed. Thanks again
@johnbobbypringle
@johnbobbypringle 9 месяцев назад
did you split your data right? Your X_train and y_train should be the same length. and your X_test and y_test should be the same length. And if that's not the problem, then ensure you are evaluating the metrics using y_test and y_pred and not y_train and y_pred?

I know that the features are helpful when we train models like XGBoost, but here we only used the ds and y column. I'd just like to understand what was the reason why you created it and if there are any ways to use this dataframe with Prophet?

Hey rob, in general, which TS model would you recommend as best for forecasting(not considering the MAPE values) for univariate dataset? Something that is consistently reliable.
@robmulla
@robmulla Год назад
Thanks for the question. I think it really depends more on the data and the information around it than the model. No model is perfect, but picking the correct one depends a lot on what you are trying to achieve- explainability, accuracy, etc. Sorry for the non-answer but if it was that simple everyone would just use one model.

I’m new into TS forecasting and trying to build an approach towards how to make the process efficient. Would you suggest that one always runs all known models to assess which one is most accurate in the latest test or settle with one model which is consistently more accurate?

Hi Rob, I wanna ask you about: How safe is use Prophet Forecast with a business data? I mean, some business have a strong data policy and I'm not sure if using Prophet could break it. Is prophet in some way collecting some part of data? With the Facebook's background about data management I think it's a better idea to ask before.

Hi Rob, thanks for sharing this. One question - what if i have many products to forecast sales, do i need to train/run model for each product? Or i could do this in one shot meaning ONE model to cover all products?
@rafaeel731
@rafaeel731 11 месяцев назад
I guess you have longitudinal data and in this case you have a collection of time series, not one. In that case you can build a model per product, or use a global model. See M4 / M5 competitions. It is greatly harder to forecast from such data. If I misunderstood, ignore me.

@thecaptain2000
@thecaptain2000 9 месяцев назад
Thank you for the informative video. however there are two aspects which are puzzling ( am new to pandas and prophet, so please be indulgent) first, once you trained your model you perform: pjme_test_fcst = model.predict(pjme_test_prophet). And it is puzzling why you are passing pjme_test_prophet. Test data are not used to perform any error measurement against predicted data, my speculation is the only column taken into consideration is the 'ds' column, used to specify what predictions we want and not the 'Y' column. am I correct? Moreover looking at yhat_lower and yhat_upper for 2015-01-01 01:00:00, meaning one hour after our training data finish, the predicted values are 23737.947439 32670.335550, a range of about 10K, which is about 50% of yhat_lower and about 30% of yhat_upper which would make for a pretty bad model if it needs such a big interval of confidence; if I understood correctly, did I?

But things in data science change daily and I’ve heard some big companies use transformer architectures in forecasting.

I was also going to respond with the "all models are wrong" quote, but Gerald beat me to it. Especially with forecasting you need to first ask yourself what the end goal is. I also think in most cases a human in the loop is still required, so an explainable model can be very helpful. But I totally agree that trying to predict something like stocks at large time horizons is a fool's errand.
