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.

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.

14 Golden Nuggets to Demystify Data Science for Aspiring Data Scientists

14 Golden Nuggets to Demystify Data Science for Aspiring Data Scientists

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.”

The 7 NLP Techniques That Will Change How You Communicate in The Future (Part II)

From machine translation that connects humans across cultures, to conversational chatbots that help with customer service; from sentiment analysis that deeply understands a human’s mood, to attention mechanisms that can mimic our visual attention, the field of NLP is too expansive to cover completely, so I’d encourage you to explore it further, whether through online courses, blog tutorials, or research papers.

The 7 NLP Techniques That Will Change How You Communicate in The Future (Part I)

The 7 NLP Techniques That Will Change How You Communicate in The Future (Part I)

NLP is certainly one of the most important technologies of the information age. Understanding complex language utterances is also a crucial part of artificial intelligence. Fully understanding and representing the meaning of language is an extremely difficult goal. Why? Because the human language is quite special.

The 10 Mining Techniques Data Scientists Need For Their Own Toolbox

The 10 Mining Techniques Data Scientists Need For Their Own Toolbox

Data mining  is  the process where one structures the raw data and formulate or recognize the various patterns in the data through the mathematical and computational algorithms. This helps to generate new information and unlock various insights. In this article, I want to share the 10 mining techniques that I believe any data scientists should learn to be more effective while handling big datasets.
