Is blunder a stupidity or foolishness?

Either and sometimes even neither

Its neither if its a 'subtle' blunder due to a deep miscalculation/missing something non obvious etc.

But that sort of thing arguably isn't "really" a blunder......

What'sw the difference between a sphere and a ball?

Normally no difference - it's assumed that the ball is (nominally) spherical - not a rugby ball. "Sphere" is a little pompous ... but how are these terms associated with chess?!

Nothing...This is "The English Language" thread from "not chess" section. I HAVE encountered "sphere of activity" vs "scope of a piece, though.

What does the underlined 'to' mean in:

Various algorithms have been developed to cluster different types of time series data. Putting their differences aside, it is far to say that in spirit they all try to modify the existing algorithms for clustering static data in such a way that time series data can be handled or to convert time series data into the form of static data so that the existing algorithms for clustering static data can be directly used.

Ah! "Sphere of activity" has very little (if anything) to do with balls - it just means the area of things that were done, the things that took place. "Ball of activity" is *not* a synonym - that would mean nothing - so in "Sphere of activity" - sphere and ball are not at all similar.

The underlined "to", above, forms part of what is grammatically know as a to-infinitive form of a verb. Therefore it is simply part of the verb "to convert".

The presence of the conjunction "or" immediately before "to convert" may have thrown you.

There is another example of the to-infinitive at the start of your text - " Various algorithms have been developed to cluster … "

It means "... in order to convert ...".

...try to convvert....?

It's quite a technical paragraph, but I think the relevant sense of the second option is

they all try to modify the existing algorithms for clustering static data in such a way (as) to convert time series data into the form of static data so that the existing algorithms for clustering static data can be directly used.

Whaat does 'resspectively' refer to?
Studies using clustering algorithms, similarity/dissimilarity measures, and evaluation criteria reviewed in Section 2.1, 2.2, and 2.3, respectively, are as italicized.

Does it coves just its clause or the whole sentence?

It means that section 2.1 reviews studies using clustering algorithms, section 2.2 reviews studies using similarity/dissimilarity measures, and section 2.3 reviews studies using evaluation criteria.

That sort of sentence construction is used where

2.1 is clustering algorithms
2.2 is similarity/dissimilarity measures
2.3 is evaluation criteria
