Divide and Conquer Algorithms

Divide and Conquer Algorithms

A very popular algorithmic paradigm, a typical Divide and Conquer algorithm solves a problem using following three steps:

  • Divide: Break the given problem into subproblems of same type.

  • Conquer: Recursively solve these subproblems

  • Combine: Appropriately combine the answers

Decision Trees: How to Optimize My Decision-Making Process?

Decision Trees: How to Optimize My Decision-Making Process?

The major advantage of using decision trees is that they are intuitively very easy to explain. They closely mirror human decision-making compared to other regression and classification approaches. They can be displayed graphically, and they can easily handle qualitative predictors without the need to create dummy variables.

The 5 Fundamental Running Times in Computer Science

The 5 Fundamental Running Times in Computer Science

As you see, you should make a habit of thinking about the time complexity of algorithms as you design them. Asymptotic analysis is a powerful tool, but use it wisely. Sometimes optimizing runtime may negatively impact readability or coding time. Whether you like it or not, an effective engineer knows how to strike the right balance between runtime, space, implementation time, maintainability, and readability.

k-Nearest Neighbors: Who are close to you?

k-Nearest Neighbors: Who are close to you?

The k-Nearest Neighbors algorithm is a simple and effective way to classify data. It is an example of instance-based learning, where you need to have instances of data close at hand to perform the machine learning algorithm.

These talks cover a wide range of topics: from showcasing your work to connecting with data leaders, from telling a persuasive data story to debugging myths in data science. I took some detailed notes of all the talks and decided to use this post to share the main takeaways.

25 Critical Insights From Experienced Data Scientists in The Data Science Handbook

25 Critical Insights From Experienced Data Scientists in The Data Science Handbook

I would highly recommend you to read The Data Science Handbook. The data scientists in the book have helped create the very industry that is now having such a tremendous impact on the world. They discuss the mindset that allowed them to create this industry, address misconceptions about the field, share stories of specific challenges and victories, and talk about what they look for when building their teams.

How to Think Like a Data Scientist in 12 Steps

How to Think Like a Data Scientist in 12 Steps

At the moment, data scientists are getting a lot of attention, and as a result, books about data science are proliferating. While searching for good books about the space, it seems to me that the majority of them focus more on the tools and techniques rather than the nuanced problem-solving nature of the data science process. That is until I encountered Brian Godsey’s “Think Like a Data Scientist.”

15 Systems Thinking Guidelines to Live in a World of Uncertainty

15 Systems Thinking Guidelines to Live in a World of Uncertainty

Systems thinking is a way of seeing the world as a series of interconnected and interdependent systems rather than lots of independent parts. As a thinking tool, it seeks to oppose the reductionist view — the idea that a system can be understood by the sum of its isolated parts — and replace it with expansionism, the view that everything is part of a larger whole and that the connections between all elements are critical.
