Analyzing How AI Performs Compared To The Human Brain


As computers get “smarter” every year, I think it is interesting to look at the state of the art and summarize how we humans perform against AI, task by task. First of all, we are going to look at the main components of a computer’s hardware and compare them to our brain. Then, we will see how that translates into an ability to use real intelligence.

So let’s jump into it:

The brain is an expensive organ in terms of energy consumption: on average, your brain consumes about 20 percent of your body’s energy, and that’s in a resting state…

Connectomics and the future of Neuroscience


The race to map the human brain that we are witnessing has resulted in an explosion of techniques to measure neural activity.

In my previous article, I talked about fMRI (functional magnetic resonance imaging) and complained about its main pitfall: it cannot record the activity of neurons — instead, the images you see of particular brain regions being lit up reflect blood flow in certain areas of the brain.

In fact, the signal you see reflects the relative presence of oxygenated versus deoxygenated blood; active regions require more oxygenated blood, so scientists can infer neuronal activity based on this measure.

Shedding Some Light On The Brain Scans Crisis


I get it, brain scans are cool. Since 25 years ago, brain scans have been a very attractive topic for research and have managed to attract vast amounts of funding. I can understand that titles like “Vegetative state patients can respond to questions” or “This is your brain on writing” have the potential to attract people’s attention to neuroscience for the first time, and that’s a good thing.

However, things got messy in 2009, But in 2009, researchers put a dead salmon into an fMRI scanner, just to see what would happen. To their surprise parts of the brain lit…

Don’t Waste Time Tuning Hyperparameters Never Again


I became a data scientist because I like finding solutions for complex problems, the creative part of the job and the insights I gain from the data is what I enjoy the most. The boring stuff like cleaning data, preprocessing, and tuning hyperparameters brings me little joy, and that’s why I try to automate these tasks as much as possible.

If you also like automating the boring stuff you will love the library I am about to introduce in this article.

As I mentioned in a previous article, the current state of the art in machine learning is dominated by…

Build and Deploy Your Own AI Platform with Python and Django


The rise of Artificial Intelligence has made machine learning platforms (ML as a service) become popular. If your company is not into building a framework and deploying their own models, chances are they are using some of these platforms like H2O or KNIME.

Even many data scientists who want to save some time are using these tools to quickly prototype and test their models, deciding later whether they are work further work or not. …

What Geniuses Can Teach Us About Intelligence


We are living in the age of cult to intelligence. Never before was being intelligent more valued than in today’s society. Kids don’t wanna be soccer players or actors anymore, they want to build the next Google or Facebook, they want to matter, to be creative, to change the world.

In a capitalist society, being intelligent very often is equated to being successful, and nobody wants to be thought a fool.

Look at the dictionary we might find definitions like ‘the ability to think, reason, and understand instead of doing things automatically or by instinct’. …

These Companies Could Win the Race for Brain-Computer Interfaces before Elon Mask’s Neuralink Does


I am sure that Elon Musk’s neuroscience startup, Neuralink is the first company that comes to your mind if you think of brain-computer interfaces. Last year, Neuralink implanted a brain chip on a pig and earlier this year, Elon said that Neuralink is “working super hard to transition from operating on monkeys to human trials by the end of the year”.

Elon Musk Introducing his Brain Chip on a Pig

However, in 2019 he said the same thing, and nothing happened. Safety is a great issue when we are talking about drilling into a human skull and even when it’s…

Non-Invasive BCIs are going Mainstream


The time has come, Brain-Computer Interfaces are not science fiction anymore but a tangible reality that we can buy, In fact, the market for this technology is expected to reach USD 288.4 million by 2025, from USD 184.2 million in 2019.

While Elon Musk’s Neuralink might start human trials this year, there are many other innovative companies offering wearable BCIs that don’t require surgery.

Non-invasive BCIs are set to change the way we communicate with our devices (smartphones and computers) and even with one another. …

2021 Updates on our Roadmap to the Connectome

During the last decade, we have seen an explosion of efforts to map the human connectome, which translates into drawing 10¹⁵ connections between 100 billion neurons in the brain. The advances made in brain imaging together will an astonishing increase in sheer computing power, have paved the way for scientists to start seeing such an intimidating task as feasible.

In this article, I will leave aside the questions about how useful the brain map will be (would you understand how a car works just by looking at the engines?) or what kind of connectome do we want to map (every…

Causal Forecasting with CausalNex


Causal Networks are having a huge impact in the world of Artificial Intelligence and their importance is only going to grow. Since Judea Pearl and his colleagues created a mathematical language for causality termed “do- calculus” we have a way to explicitly calculate causal effects and therefore we can answer “what-if” questions a.k.a we can make predictions.

I’ve picked up boxing for this article for two reasons. First, it’s my favorite sport, but most importantly it is a very explicit example of cause and effect isn’t it?

I believe even a 5 years old kid knows pretty well that it’s…
