How can GA help cut down problem space and converge towards a better solution?
If you have heard of systematic trading or algorithmic trading, then you must know that optimization of strategy is among one of the most important factors that dictate whether the strategy would even break even. And the worst part is: optimization is very computationally heavy. …

Time to stop being too dependent on .iterrows() and .apply()
Python, arguably the coolest programming language these days (thanks for Machine Learning and Data Science), is not very well known for its efficiency when compared with one of the best programming language — C. An example of this would be conditional logics. When developing machine learning models, it is quite…

You don’t always need indices
Welcome to a series of short posts each with handy Python tricks that can help you become a better Python programmer. In this blog, we will look into how to unpack iterables.
You don't need indices.
Say you have a tuple ("a", "b", "c").
If you want to assign the first element to a…
How do generators work in Python?
Welcome to a series of short posts each with handy Python tricks that can help you become a better Python programmer. In this blog, we will look into generators.
Introduction
A generator is a subclass of a iterable.
To understand how generators work, we will need to first revise how iterables…
Are you still iterating through for loops?
Welcome to a series of short posts each with handy Python tricks that can help you become a better Python programmer. In this blog, we will look into how to flatten lists.
Situation
We have all dealt with lists of lists or even worse: lists of nested lists.
Theoretically, we can…
One keyword argument that saves you some frustrations
Welcome to a series of short posts each with handy Python tricks that can help you become a better Python programmer. In this blog, we will look into checking joins in Pandas.
Situation
When we work with a collection of datasets in Python, knowing how to join the tables together is…
How to compare multiple variables with a single value at once?
Welcome to a series of short posts each with handy Python tricks that can help you become a better Python programmer. In this blog, we will look into variable comparisons.
Situation
You have variables x, y, z, and you have also got a constant c that you would like to check…
How does boolean evaluation help shorten if statements?
Welcome to a series of short posts each with handy Python tricks that can help you become a better Python programmer. In this blog, we will look into boolean evaluation.
Situation
Let’s say we have a variable x and we would like to do something if a certain condition is met…
What are the impacts? And how can we avoid them?
A common machine learning modelling process goes by (1) weight initialization, (2) forward propagation, (3) loss (or cost) computation, (4) backpropagation, and (5) weight update using optimization algorithms. …

What is Attention Mechanism & Why is RFA better than Softmax?
Google has recently released a new approach — Random Feature Attention — to replace softmax attention mechanisms in transformers for achieving similar or better performance with significant improvement in time and space complexity.
In this blog, we will look into the background of transformers, what is an attention mechanism, and…
