A very comprehensive video, thank you. A question I have, you mention that if you have multiple dataset at different time periods, that these can be combined together and have 1 model trained, instead of multiple models e.g. Daily, Weekly, Monthly. My datasets are identical, just the datetime is changing. Does this also apply for other models such as RandomForestClassifier?

You are creating amazing videos! Thank you! So well explained, easy to understand, helps to solve real ML problems and at the same time entertaining! Please keep creating more:))

Thank you for such an amazing video!!! It is incredibly useful!!!

Hi Mario, and thank you for a very clear and concise explanation. One question I have is, how would you handle it if several of the products are only selling intermittently such that there are many zeros in the series?

where are new videos!!!

More intriguing question is: how to train a model, based on thousands of timeseries, determined by multiple parameters, and then to simulate/forecast single timeseries, based on new set of the respective parameters

Very nicely explained. Your videos are good. Why did you start making them?

Thank you a lot!

It would be better if you use slides with key points. It was distracting by the 'hand-writing' on the screen & hard to read. Anyway, thanks

Thank you very much for this amazing video ! Can we use Cross Validation for hyperparameter tuning in the case of RandomForest with time series data ?

Should i learn feature Engineering in 2024?

i can do the same processus if in place of week i have a date like yyyy-mm-dd and how to handle the year?

Thank you. You did so very much in such little time in comparison to TWO different bootcamp instructors could in so much time...

How do I find the season effect features?

how do I find the season effect features?

🎯 Key Takeaways for quick navigation: 00:00 📊 *Understanding Feature Engineering for Tabular Data* - Feature engineering is essential for high-performance machine learning models. - The key to feature engineering is aggregation, which involves grouping and summarizing data. - Aggregations can be applied to various types of data, including categorical and numerical variables. 06:22 🔄 *Common Feature Engineering Techniques* - Feature engineering techniques include lag, difference, rolling, date components, and time differences. - Lag captures the previous value of a variable in a sequence. - Difference calculates the difference between consecutive values in a sequence. - Rolling involves computing aggregations over a rolling window of data. - Date components extract information like month or day from dates for seasonality patterns. - Time differences measure the time elapsed between events. 15:21 🧩 *Reverse Engineering Features from a Kaggle Solution* - Analyzing features from a Kaggle competition example. - Median time between bids can be computed by grouping by user and calculating time differences between bids. - Mean number of bids per auction is determined by grouping by user and auction, then counting bid occurrences. - Detecting IP addresses used by both users and bots involves complex filtering and merging based on IP data. 21:05 🌐 *Advanced Feature Engineering* - Geolocation features can be important, calculating distances between locations, and spatial data aggregations. - Network or graph features involve representing data as graphs and computing graph-related metrics. - Suggests exploring the Instacart competition for advanced feature engineering with multiple tables. 22:16 📺 *Conclusion and Next Steps* - Encourages viewers to like, subscribe, and leave comments. - Offers a link to a time series forecasting workshop for further learning.

I just checked this amazing video after your feature selection engineering video! I have no idea why this is video isn’t popular!!! Respect the effort you spent on this!

I am in a Kaggle competition. Learnt a lot from this video!! Thank you so much for uploading this video for us!!

Thank you.

Love the videos and blogs- absolute mad content, thank you very much

Fantastic video, so many useful references, I'm glad I watched the entire thing!

Why dont we use product_code as one of the features while training?

how i future forecast with this method ? Ex: forecast week 52 ? i think, need to forecast another series too for another features .

Nice! It would be interesting to see what to do if the time series have different lengths.

Are we going to get a video on cross-validation and selecting the right model? Your time series videos have been a wealth of knowledge.

Mario, boa tarde. Tem algum dica para usarmos a LSTM para predições com passos à frente em um sistema MISO? .

Hi Mario, thanks for the wonderful presentation. One qouestion, how could you use the feature the "Sales" to predict sales? Using that features, when you predict using .predict function, you have to pass that as an argument. In reality, you would not have that information available.

Good One!!!!! Expecting more from You!!!!!!

I just found your video and it's great. The reference to FeatureTools was frustrating to say the least. The documentation on the site is not working and the github repo also has examples that just don't work. It's too bad

Hello Mario, I have a question... how does the model know that we're trying to predict multiple products at once? I've trying to train a model in order to predict the sales of 2000 SKU and the main concern I have now is how to do it efficiently. I watched everything that you did but I still have the same problem, do you know where I can find an example of it? thank you very much for your video

Thanks for the useful video. Sorry, is it possible to implement independent spatial sequences simultaneously? I have a dataset which is consist of 1000 independent spatial sequences with dimension 2*7 (2 for x and y, and the length 7 for positions in each time). I implemented it with Simple RNN, LSTM and GRU. Can I do it with transformers (attention mechanism)? Could you introduce me a practical example?

🤘 ρгό𝔪σŞｍ

give more, please!

Thank you! :) ♥

I used this on my last project. It is very important to read the library documentation and find this unbalanced parameters.

Hi, Mario. Big fan of yours from DataHackers here! Do you know if the same applies for imbalanced data sets for anomalies detection? Such as default prediction or fraud detection problems? It's, usually, not a problem from sampling, but its from the nature of those problems having such imbalanced data... Don't know if it would end up creating bias or data leakege because of it...? Do you know better technics for this kinds of problems?

Very clear explanation! Thank you for the video Mario

Loved the way you presented.

Clear, objective and very practical - congratulations!

Thank you so much man crazy good explanation

Por essa eu não esperava kkkk

It would be great if you could show demo also , thank you for information

Difference between time features would lead to negative values. Do we take min max scaler after that?

Thanks for your useful video. Sorry, If our dataset has two target columns how can we write the codes?

Thank you for making the topic simple. Since you have combined all the product sales to train and validate your model, How can one use this model to predict sales for 'any single' product only?

This channel is a hidden gem !!!

Thanks for this tutorial. Will you provide some videos about many features? Thanks!

The Simple Imputer will impute mean values for the entire column in the missing values. Shouldn't that be done product wise as well? Thanks for a wonderful lecture btw :-)
