Deep Studying Illustrated, Half 1: How Does A Neural Community Work? | by Shreya Rao | Jan, 2024


An illustrated and intuitive information to Neural Networks

If in case you have learn my earlier articles, you’ll know what’s coming subsequent. On this a part of the web, we take complex-sounding ideas and make them enjoyable and nbd by illustrating them. And in case you haven’t learn my earlier articles, I extremely advocate you begin with my collection of articles masking the basics of machine learning since you’ll discover that loads of the fabric lined there’s related right here.

Right now, we’re going to sort out the massive boy — an introduction to Neural Networks, a sort of machine studying mannequin. That is simply the primary article in a complete collection I plan on doing on Deep Studying. It is going to deal with how a easy synthetic neural community learns and offer you a deep (ha, pun) understanding of how a neural community is constructed, neuron by neuron, which is tremendous important as we are going to proceed to construct upon this information. Whereas we are going to dive into the mathematical particulars, there’s no want to fret as a result of we are going to break down and illustrate every step. By the top of this text, you’ll understand that it’s waaaaay less complicated than it sounds.

However earlier than we discover that, you may be questioning: Why do we’d like neural networks? With so many machine studying algorithms out there, why select neural networks? The solutions to this query are plentiful and extensively discussed, so we received’t delve too deeply into it. However it’s price noting that neural networks are extremely highly effective. They’ll determine advanced patterns in knowledge that classical algorithms might battle with, sort out extremely advanced machine studying issues (akin to pure language processing and picture recognition), and diminish the necessity for in depth characteristic engineering and handbook efforts.

However all that stated, neural community issues just about boils all the way down to 2 principal classes — Classification, predicting a discrete label for a given enter (ex: is that this an image of a cat or a canine? is that this film overview constructive or adverse?) or Regression, predicting a steady worth for a given enter (ex: climate prediction).

Right now we’ll deal with a regression downside. Take into account a easy state of affairs: we just lately moved to a brand new metropolis and are at the moment trying to find a brand new residence. Nevertheless, we discover that the costs of homes within the space range considerably.

Since we’re unfamiliar with the town, our solely supply of knowledge is what we…
