Have you ever wondered how information is represented within a neural network?

All the inputs, outputs, and transformations are represented by data structures, referred to as tensors. Now you probably are wondering, what are really tensors?

The term “tensor” is more a mathematical generalization of many concepts rather than one…


Recall that supervised learning is when algorithms are trained off of labelled data. Each input passed into your model during training is a pair that includes the input object and its corresponding value. …


An auto-encoder is a sequential neural network, consisting of two components, the encoder and the decoder.

Let’s say we were dealing with images. Our encoder would extract features from the image which would reduce some components like its height and width, but makes a latent representation for the image. …


The brain is a miraculous organ, and that's not a secret to anyone. Our brains may only be 3 pounds, however, it's the powerhouse of intelligence, interpretation, initiating body movement, and is the steering wheel that controls all of our behaviours.

Although the brain is one of the most important…


Today doctors have a limited view of what goes on in our body.

They can talk to us, take scans, run tests, and examine genetics, which all play as powerful tools for diagnosing an illness, but currently, there is only so much you can do in terms of early diagnoses.


I don’t have many clear memories from my early childhood.

In fact, most of my hazy memories consist of me playing log tag outside with my friends, sharing snacks at lunch, throwing crabapples at moving cars (yeah… my friends and I probably shouldn’t have done this), and trading Pokemon cards…


To some people, the idea of a brain-computer interface may seem alarming, if not scary.

There are a lot of dystopian ideas associated with these devices, such as that people will be able to control your mind, telepathy, A.I. will take over your brains, you’ll become a cyborg.

Although brain-comper…


The Canadian Cancer Society presents the following statistics related to brain tumours in 2020:

  • Approximately 3,000 Canadians are to be diagnosed with brain and spinal cord cancer
  • An estimated 2,500 Canadians will die from brain and spinal cord cancer
  • Approximately 1,700 men will be diagnosed with brain and spinal cord…


Some Context

If you don’t already know, I belong to an amazing STEM program called The Knowledge Society. During the month of November, innovators from TKS Toronto had the opportunity in teams to come up with a solution to improve customer service at Instacart. …

It’s insane how you can detect pneumonia in images using deep learning models, saving an individual’s life. According to the World Health Organization, pneumonia kills around 2 million children under the age of 5 years and is repeatedly estimated as the single leading cause of child mortality. …
