Carbon capture via seawater electrolysis.

Written in Collaboration with Devinder Sarai, Sophia Moloo, and Naila Moloo

Abstract

The climate crisis is not fresh news. It’s been happening for years now, but is nearing the point of being irreversible. When examining the causes of a calamity like this it’s safe to say that there are more than one, but carbon dioxide emissions are certainly a large contributor, especially as they are caused by human activity. Carbon dioxide is a natural gas that we breathe out, but when fossil fuels like oil and coal are burned, and pursuits like deforestation occur, there results in an excess amount in…


If you heard the following sentences during a conversation you could likely figure out the sentiment category — either calm, happy, sad, angry, fearful, surprise, and disgust — they fall under.

“Hey! Happy Birthday!”

“I just lost my job. I don’t know what to do.”

“Wow! I was not expecting a surprise party.”

Can a computer categorize voice in the same way? Both Devinder Sarai and I wanted to find out as over 32 000 000 people in the United States alone struggle to recognize others’ feelings due to Autism or a condition called Alexithymia.

People with these conditions know…


Nanoscience is the study of structures and materials on an ultra-small scale. But just how small is ultra-small and why should you even care about these materials?

To help you understand just how tiny nano-materials are a nanometre is one-billionth of a meter. To give you context behind that statistic, nanoparticles are usually 500–100000 times ‘thinner’ than a human hair!

For the majority of human history, humans could only make use of the materials they could see with microscopes or touch with their hands. …

“If you heard this legendary lyric out-loud, I’m sure you would be able to understand or classify the words being said.

Well, a Convolutional Neural Network (CNN) can also classify audio clips into distinct words! In this article, I will:

  1. Explain how a CNN can do this.
  2. Explain why classifying audio clips with machine learning(ML) can help with efficiency, health, and well being.


Imagine that it’s 2017, and you’ve just been promoted to vice president of Alibaba Group and the general manager of the Rural Taobao initiative.

Your job is to work on Rural Taobao, an initiative designed to attract hundreds of millions of Chinese rural villagers to use Taobao—Alibaba’s consumer e-commerce marketplace. Oh, and also, you need to figure out how to make a financially sustainable business model.

This initiative is on version 3.0, meaning that it has failed twice before. The company is counting on you to make it work — you are their last shot.

A lot of money and…


How are you doing? Oftentimes the answer to this question is— I’m good! Because of this default answer, it can be hard to determine how the person you are chatting with is really feeling. Are they actually happy and healthy?

Doctors often feel the same uncertainly when they are attempting to evaluate whether someone has a mental disorder that is tricky to diagnose, such as depression.

The uncertainty that doctors face is a huge problem as depression is a leading cause of disability worldwide. …


The tech community is amazing! We help each other by open-sourcing resources and sharing knowledge on platforms such as GitHub and Stack Overflow. There are over 100 million repositories now live on GitHub and over 18 million questions and 27 million answers on Stack Overflow.

This feature of the tech community really helped me during the past two weeks when I was exploring the sentimental analysis of text. I was amazed at all the open source libraries available to help me tinker with sentimental analysis!

But this got me thinking: Why are companies open-sourcing these Machine Learning (ML) libraries? In…

Can you think of a politician or a person of influence who is driven only by a goal? Do they make you feel uncomfortable, unsafe, or even angry? Why?

Unquestionably, these people can be ruthless in achieving their goals and are indifferent to the consequences of their actions. As a result people unjustly get hurt along the way.

These people and Machine Learning (ML) are very similar in the sense that they do not care about how they achieve their objectives unless there are measures put into place to monitor them.

However, ML has many advantages over people in achieving…


Shoot, you’ve injured your arm! It was hurting for some time, and you think it may be broken — so you decide that you need to go to the hospital as you are having trouble navigating day-to-day life.

Once you get to the hospital, you have an interview with a doctor for an assessment of your symptoms and history of arm injury. You are asked a series of questions such as:

Have you felt pain in your arm lately? How does that affect you? Does your arm improve or get worse as the day goes on? …
