Are Transformers useless for time series forecasting? NO! We showcase how Transformers achieve SOTA results, beating DLinear models.
Here's a blog post introducing the Autoformer model and how effective it can be at #timeseries #forecasting: huggingface.co/blog/autoformer
Here's a blog post introducing the Autoformer model and how effective it can be at #timeseries #forecasting: huggingface.co/blog/autoformer
The paper "Are Transformers Effective for Time Series Forecasting?" arxiv.org/abs/2205.13504, claims that a simple linear model DLinear outperforms Transformer based models by a large margin.
Why does that happen in their case? Firstly, they compare a linear model with massive models, and they even acknowledge it. Secondly, they compare their univariate model with multivariate versions of the Transformers, which on the small datasets gives poor performance.

🎉 We are thrilled to announce the release of the latest version of mlforecast a #Python library for Scalable #machinelearning 🤖 for #timeseries #forecasting
🚀 This version comes with exciting new features that are sure to make forecasting even more efficient and accurate

🔮 Conformal Prediction: We've added the ability to generate probabilistic forecasts using conformal prediction. You can choose the levels of your intervals and the number of conformity scores to use.
⚡️ In addition, mlforecast includes the capability to fit multiple time series with global models. That means you don’t need to calculate sequential conformal intervals for each series and period. I.e., conformal prediction for time series just got a lot faster and easier. 🤯
🎉 We are very excited to release the new features of NeuralForecast! 🥳🚀
With this release time series forecasting with neural models is even more accessible and powerful. Here are some of the highlights

This research aimed to forecast the temporal variability of POC in Indonesian waters.
POC forecasting is essential in predicting the productivity of Indonesian seas, for several reasons, namely, that it will affect marine productivity, the Indonesian seas are dynamic, and the existence of global threats to the ocean (climate change, ocean acidification, and d'Ox)

Walmart has been using time series forecasting for decades to predict sales and optimise inventory levels.
By analysing historical sales data, weather patterns, and other factors, they're able to make more accurate predictions about future demand for products.

Thanks ICP for publishing this essay on #Ritamic Decision Policy. Into year-3 of this series, this post summarizes manthan, research and study of the Vedic origins of sustainable decision policy and strategy, with contemporary examples all can relate to.
Post focuses on sustainable policy to make not one, but a series of interconnected decisions over time.
Can ideas of Vedanta be applied here?
short ans: Y.
Content is of interest to those making gov or private policy, designers, startups, #Ganita/stem students, young parents.

The possibility of LeBron getting to Kareem's mark by game 49 has gone up. Currently, the most likely range is game 48 to 52, with 80% of the results falling in that range. We are 94% sure that LeBron gets there by game 52.
There are very small chances that LeBron's quest extends into games 55, 56, or 57. Similarly, a small set of simulations (<2 percent) point to games 44 and 45.
Game one has come and gone. Here is how the predictions have shifted for LeBron eclipsing Kareem.

Lebron scored 31 points in the first game of the season. 31 is a better score than 70% of the games Lebron played in the last three seasons.

When it comes to Time Series, colleges and universities have it all wrong.

Universities are stuck in the past, teaching ARIMA.
But the cold reality is that ARIMA is NOT winning time series competitions & ARIMA is NOT helping companies solve BIG forecasting problems.
But the cold reality is that ARIMA is NOT winning time series competitions & ARIMA is NOT helping companies solve BIG forecasting problems.
To be frank, ARIMA is too slow.
When you use ARIMA, you fall into a trap. You think, hey, this is what they're teaching me...
It must be good, right?

Howard Marks en son yazdığı “memo”sunda makroekonomik tahmin yapmanın gerekliliğini sorguluyor.
Bir tahmin yapıyorsak bazı varsayımlara göre yapıyoruzdur. Yoksa atmasyon bir şey olur. Yapılan her varsayım ise bizi gerçeklikten uzaklaştırıyor.
Bir tahmin yapıyorsak bazı varsayımlara göre yapıyoruzdur. Yoksa atmasyon bir şey olur. Yapılan her varsayım ise bizi gerçeklikten uzaklaştırıyor.
Tahmin yapmak, normalde hayli karmaşık etkileşim içinde olan bir sürü veriye, gelişmeye aynı anda hakim olmayı gerektiriyor. Pozitif bir bilim olmayan ve insan davranışlarına oldukça duyarlı iktisatta ise doğru tahmin yapmak neredeyse imkansızlaşıyor.
Geleceği tahmin ederken geçmiş iyi bir rehber midir, yani her bir durum karşısında hep aynı şeyler mi olur (stationarity)? Pozitif bilimlerde bu geçerli olabilir. Ama iktisatta hep düşünmediğimiz bir şeyler mutlaka vardır ve her zaman beklenmedik bir şey olur.
Another great development from @nixtlainc, ETS from StatsForecast is much more accurate and over 100 faster than NeuralProphet.

Last year a few data scientists including myself exposed severe issues with facebook prophet resulting in facebook pulling down claims such as “with facebook prophet anyone can produce better forecasts than human experts “.
Still the hope was that with Neural Prophet things will be better and one can at least partially repair the worst forecasting model of the XXIst century - Facebook Prophet. valeman.medium.com/benchmarking-f…

First, let's define "prediction". A useful #earthquakeprediction will tell you where, when, and how big a significant #earthquake will be, with a reasonably high success rate.
