What is Time Series Analysis?

[@tyronefrielinghaus3467]

Of all the IBM presenters, he's the best. Clear, great presence...and amusing in an understated way.

Time series analysis 1: Components of TSA (Trend (direction of data), Seasonality (pattern of data), Cycle (bumps and boost in financial), Variation (unpredictable, noise, data behaviour difficult to classify). 2: Models: Like ARIMA (considering past values after future values; trends and seasons; smoothing noise), Exponential smoothing (does nos have seasonality, gives more weight to recent values model), … 3: Implementation: like Python using Pandas and Matplotlib libraries to preprocess and plot. Whether to choose components and models depends on the problem we are choosing to solve…

I am the accountant man. Just trying to changing career into Data Analyst, using the most current and advanced digital apps and tools for Data Analysis. This is grade A-level presentation. Thank you very much. [Greetings from Jakarta - Indonesia - South East Asian]

God evening, I'm Al-ameen from Kano state Nigeria. I'm a student trying to focus on data analysis, I need your guidance please as I can see you are directing towards becoming data analyst. Thank you.

Bro just explained Time Series Analysis in the amount of time it would’ve taken my teacher to open their laptop

[@enverpedro9751]

i wrote exam on this took me 5hours to understand this when he does it in 7mins

[@abdulazizalfaifi7228]

Bro just explained what my profs have been teaching an entire year in 7mins 😮 they too need to attend here.

[@abiofficial-ws7pn]

Of course, I came here for Time Series, but he is so soothing. Sometimes, I watch his explainers just for that.

[@ShaminChokshi]

This guy is a legend! Writes everything backwards and explains

[@riyyengar]

You got very good accent very good pleasing frequencies.. no nonsense technical subject you teach, overall you are a good teacher and I am happy I listened this lecture 🙏

[@seriestemporais]

Great video, congrats! As introductory video, I have just missed the concept of autocorrelation (even in a qualitative manner), which differs time series analysis from a formal statistical analysis and makes a huge difference for forecasting.

[@razaqalghiffari9365]

I like the explain time series in IBM when, bored in class 😅 thanks for teaching

[@sanjaisrao484]

wow so clear and short explanation, thank you

[@sanjay_5548]

The claims at 5:09 are not entirely true, Holt's Linear Trend Model incorporates a trend component and Holt-Winter's Method (Triple Exponential Smoothing) incorporates both trend and seasonality. Please do make the necessary changes. Thank you.

[@DAEMANN]

You guys are just awesome in breaking down complex topics to enjoyable ed videos, focus and scope are spot on 🎉 maybe I should try your Coursera certs - is it similar to your current style?

[@Srj6662]

Nice explaination sir 😊

[@Slimgurl2290]

Great Job explaining the components

[@gulammustafa-s2u]

thanks alot for clear its example

[@princeofheaven19]

Better than my university professor

[@laurynai]

😂😂😂

[@SilasOgah-v7y]

Thanks alot I learnt something today

[@habibmaryam]

This was very helpful.

[@hewramanwaran6444]

Thanks a lot. I love your videos.

[@anirbanc88]

awesome! can you do more videos on TS? and if possible transformers in TS?

[@dipanjanpalchowdhury6012]

He explained time series in 7 minutes vs my teacher who took 4 weeks to teach the same thing.

[@reanwithkimleng]

Hello sir, time series data when cleaning missing value it consider the lag or equal interval?? Like if year 2000 to 2020 but has missing at 2010 and 2019 if we remove this year the sequence of it will loss?? How about outlier?? And so on??❤

[@fareidfareid6484]

Thanks for your efforts

[@topher_prime4823]

Could you pls Talk more on times series real life applications

[@jl_MindfulMoves]

What software do you prefer using when simulating time-series processes? I learned SAS (which I compare to an old lady), I prefer R but the output isn't so visual. Is there other better options

[@gayathriramu8831]

This is what I was searching for..

[@bussatharuni609]

so how do we solve these time series patterns using suitable machine algorithm who does we know it is suitable while actually machine learning algorithms makes suitable predictions

[@unnischoice99]

is there any free software to run time series analysis? The ones you mentioned python etc? Any free softwares for students/acedima/researchers?

[@DataDrivenDev-d5u]

Hello, how do i use models like AMIRA

[@HiltonFernandes]

It's a pity that in such a great, but short presentations, the great presenter could not mention the libraries that can help forecast the time series future values.

[@kmlumd44]

is this guy writing backwards the whole tiem?

[@kashifaziz5019]

The video is flipped

[@kallan2255]

They write normally on a special piece of glass between the camera and the presenter. They then flip the video in post. Sometimes presenters will get shirts made with the logos printed backwards specifically for this.

[@DreDr-jf3xq]

[@kimhweeseet3809]

Anyone knows what is the software / hardware used for this?

[@WiseWords-yc2oo]

How can I get job at IBM, I am a java developer

[@Flylikea]

I have the time series, but now I need to build the model for analysis... otherwise, it looks like lines 😅

[@LearningLane3456]

Sir do you cook?

[@rogerzhou8987]

Is he writing words backwards using his left hand? Amazing...

[@IBMTechnology]

See ibm.biz/write-backwards

[@Maria-yx4se]

prolly he behind glass and they just invert the vid

[@CherryKH007]

Can I have free course of this course as well as python?

[@charlesclager6808]

To me, time is a construct of the brain. When the brain ceases to function, time is gone. So what is the past, present and future ? Put simply, the past is what each one of us remembers. So the past is different for every human being alive. The present can be defined differently. To one person the present can be today, to another the present may defined as a week. To me, the present is perhaps a second, when the future time becomes the past time. So what is the future ? Again, time being a construct of the brain, the future is what we expect to happen. So again future time is different for everyone. So the inanity of time travel means that to whose time are we going to travel? Since everyone's past and future are different (in their brain) to whose past are you going to travel to ? We measure time to the atomic level. We have to measure time to survive. From the smallest amount, a second lets say. An hour, day, weeks months and so on. Our civilization depends on it. From our daily lives to our whole life plan. I could go on but these are just my thoughts for what they are worth.

[@2godbeinfiniteglory]

Okay, just want to understand how your take refers to time series analysis. Do you feel that its not as effective? due to the subjective nature of time perception across different people.

[@borntodoit8744]

​@@2godbeinfinitegloryset your scope for analysis this will ignore talking about time like Einstein (theoretical upper limits) and instead talk about it in engineering terms (practical accessible relevant limits) no need to talk about time so existentially the video was excellent stick to TS data helps predict trends, seasonality, cycles & variations

[@ethanwong3367]

how do u write on the screen like that? 🤪

I want to ask, how he write and then it could be shown us like a blackboard? what is the technique name? 🤣🤣
