Ep-2: Methods of reading Research Paper & summarizing findings

Sayma34 — Fri, 16 Feb 2024 09:45:14 +0000

Research is a very slow process from crafting till publishing. It needs only patience and perseverance. If you know the process of doing it, it should take 4–5 months approx (still depends on the person).

Method of reading papers from Literature:

Well, you can read papers in two ways (surely you may have your own reading process preferences).

In depth mode: With this, it is mainly focused on understanding a paper completely and implementing what authors have done in their own research. It is about reading the paper very thoroughly from first to last and highlighting every significant aspect. It can take maybe 3 to 4 hours.
Birds Eye View Mode: This is about not reading thoroughly but only focusing on abstracts, figures, tables, samples, discussions and conclusions in a brief manner. It may take 15-20 minutes.

Suppose you're reading 70 papers, maybe you can read 5-6 papers thoroughly and remaining majority in bird's eye view.

Ways to summarize the findings from literature review:

You might maintain a excel sheet where you add all the summary of the papers. Which may help you while writing review paper.

What is research profile?

Sayma34 — Fri, 16 Feb 2024 07:29:07 +0000

We have a wrong concept that only PhD or masters students can get them indulged to research works/ writing which is absolutely wrong. In this blog, I'm going to share every detail about crafting a research paper from first to last. Enjoy!

What is research profile? why one should care about having a strong research profile?

This thing can be thought of 5 aspects:

Research projects: It has very low value because doing projects and just adding it into your resume is not a big deal. Everybody has projects and they just add it to their resume. So it doesn't hold that much of value.
International Research Internship: It is valuable if there is tangible research outcome.
Papers: Having high quality journal paper. Then publishing it in conference and having patents. It has a really high value and makes really strong research profile.

Research papers are of some kinds:

Journal paper with new result
Literature review paper
preprints : preprints are preliminary versions of a scientific manuscript that researchers share by posting to online platforms known as preprint servers before peer-review and publication in an academic journal.

Part-5: A geometric Notion of Singularity

Sayma34 — Mon, 27 Nov 2023 12:18:06 +0000

Suppose we have a system,
a + b = 10
2a + 2b = 24

But in this system, if the solution is 0 0 , now it'll turn from a contradictory system to a redundant system. But It'll remain as Singular system. So, what I'm trying to mention is that, whether the system is singular or non-singular, this is not dependent on a constant to be determined.

So, in this case, for the equation
a + b = 0
2a + 2b = 0

Figure will be like-

Part-4:System of Equations as lines

Sayma34 — Mon, 27 Nov 2023 11:03:26 +0000

We can represent linear equations as lines in plane.
In the previous part (part-3) we saw some possible points. Let's draw, it'll be more easier to understand:

Linear Independence & dependence

Part-3: System of Equations

System of Equations

We are going to understand what a linear equation is and what a system of linear equations is.

Let's see a glimpse of linear and non-linear equations.

Linear Equation:
a + b = 10
5a + 2b = 20
9.5a + 36.6b - 3c = 155.9

In a linear equation, a, b, c were allowed only to have numbers or the scalars attached to them.

Non-Linear Equation:
It can be square (i.e: a^2 + b^2 = 10)
Can have sin, cos, tan, arc tan { i.e: sin( a + c^10 = 18)}
Can have power ( i.e: 5^a - 2^b = 0)
and so on!

Now, Suppose:

_System-1: _
a +b = 10
a +2b = 12
Solving this two equation, it gives unique solution. So, it's a complete system and non-singular.

System-2
a + b = 10
2a + 2b = 20

Solving these two equations gives infinity many solutions because the two equations are exactly the same.
As in, we can consider it as:
a = 8, 7, 6
b = 2, 3, 4
So, it's redundant and singular.

System-3
a + b = 10
2a + 2b = 24

No solution here because two equations contradict each other.

Let's talk bout Linear-Algebra and ML (Part-2)

Part:2
System of Sentences

Systems of sentences behave much like systems of equations. We'll learn more from the following examples:

Suppose there are 3 systems as followed:

System-1:
Black rose
Pink lily

System-2:
Black rose
Black rose

System-3:
Black rose
White rose

When the system is Redundant (if it's containing the same information in several lines) / Contradictory (contradictory info), then the system is called Singular System.
If it's a Complete system (having all the info) then that's called non-singular system.

There is a measure of how rudundant a system is, and that is called Rank.

Part:1
The Neural Network
Neural Network is a machine learning model that helps in image processing. So now, what if I give a picture as an input? A neural network takes it as a pixel and runs some mathematical operations on it using an algorithm. The data in the picture helps take parameters, which contribute to making the best prediction for existing data.

In the picture, those black points are neural network nodes, which are organized in layers. These layers can be expressed as a rectangular array of numbers, which is ultimately called a matrix. These image pixels are mainly simple values that are being received as input, and then the algorithm determines the output by doing mathematical operations on them. This amazing process actually reminds us of the precious existence of linear algebra. By the way, neural networks have many more amazing applications!
