What is a "time series" to begin with, and then what kind of analytics can you perform on it - and what use would the results be to you anyway? In this video, Martin explains how time series analysis can provide you with a glimpse into the future!

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

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
🙏
Bro just explained Time Series Analysis in the amount of time it would’ve taken my teacher to open their laptop
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?
Bro just explained what my profs have been teaching an entire year in 7mins 😮 they too need to attend here.
I like the explain time series in IBM when, bored in class 😅 thanks for teaching
Great Job explaining the components
wow so clear and short explanation, thank you
Thanks for your efforts
Nice explaination sir 😊
He explained time series in 7 minutes vs my teacher who took 4 weeks to teach the same thing.
awesome! can you do more videos on TS? and if possible transformers in TS?
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
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.
This is what I was searching for..
Could you pls Talk more on times series real life applications
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
Better than my university professor
😂😂😂
looking for a performance testing related detailed playlist
is this guy writing backwards the whole tiem?
The video is flipped
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.
is there any free software to run time series analysis? The ones you mentioned python etc? Any free softwares for students/acedima/researchers?
I have the time series, but now I need to build the model for analysis... otherwise, it looks like lines 😅
How can I get job at IBM, I am a java developer
Is he writing words backwards using his left hand? Amazing...

Sir do you cook?
Can I have free course of this course as well as python?
how do u write on the screen like that? 🤪

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.
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.
@@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
I want to ask, how he write and then it could be shown us like a blackboard? what is the technique name? 🤣🤣
how the duck can he write in screen?
duck around and find out
