The Foundation: Machine Learning
At the core of AI lies machine learning (ML), a paradigm that enables systems to learn from data without explicit programming. We'll delve into the basics of supervised and unsupervised learning, understanding how algorithms can make predictions and discover patterns autonomously. Concepts such as regression, classification, and clustering will be demystified in the upcoming blogs. So stay tuned!!
Back in 1959, when Arthur Samuel, the OG in computer gaming and artificial intelligence at IBM, coined the term "machine learning," it was like unleashing magic into the tech world. Picture this: a quirky "learning machine" named Cybertron, decked out with punched tape memory, analysing sonar signals and speech patterns in the early 1960s! Talk about a tech throwback! It had a human operator as its teacher, pressing a "goof" button whenever it made a hiccup. Fast forward to the '70s, and the fascination with pattern recognition was alive and well, according to the tales spun by Duda and Hart. By 1981, we were teaching neural networks to recognize not just 26 letters but a whole alphabet pool from computer terminals.
Now, let's zoom into the 21st century. Tom M. Mitchell gave us the lowdown, defining machine learning as computer programs that basically learn from experience – E for experience, T for tasks, and P for performance. Forget the jargon; let's just say machines are getting really good at what they do! It's not about asking if machines can think, but if they can do what we clever humans can. Cut to today, where machine learning is making waves in classifying data and predicting future outcomes. Think computer vision identifying cancerous moles or algorithms guiding traders through the stock market jungle. The journey from Cybertron to predicting the future – now that's one tech adventure worth diving into!
UC Berkeley (link resides outside ibm.com) breaks out the learning system of a machine learning algorithm into three main parts.
A Decision Process: In general, machine learning algorithms are used to make a prediction or classification. Based on some input data, which can be labeled or unlabeled, your algorithm will produce an estimate about a pattern in the data.
An Error Function: An error function evaluates the prediction of the model. If there are known examples, an error function can make a comparison to assess the accuracy of the model.
A Model Optimization Process: If the model can fit better to the data points in the training set, then weights are adjusted to reduce the discrepancy between the known example and the model estimate. The algorithm will repeat this “evaluate and optimize” process, updating weights autonomously until a threshold of accuracy has been met. [source:https://www.ibm.com/topics/machine-learning]
Unraveling Neural Networks: Deep Learning
Back in the day, the term "deep learning" wasn't as trendy as it is now. It's the superhero upgrade to traditional machine learning, and it all began with humble artificial neural networks inspired by our very own brains. Picture layers of virtual neurons connecting and communicating, forming the backbone of these digital brains.
Fast forward to today, and we've got the stars of the show – convolutional neural networks (CNNs) and recurrent neural networks (RNNs). CNNs have a knack for deciphering intricate patterns in images, making them the go-to for tasks like facial recognition and image classification. On the other hand, RNNs are the time-travelers of the network world, specializing in tasks where time and sequence matter, like predicting the next word in a sentence.
But how do they learn? It's like a digital dance of data. These networks are fed tons of examples, learning to recognize patterns and make predictions by adjusting their virtual synapses. It's like teaching a virtual pet some tricks, only way cooler.
When you hear about a machine beating a human at chess or composing music, it's the genius of deep learning at play. These neural networks, armed with layers of learning, can understand, reason, and make decisions on par with – or sometimes even surpassing – us humans.
Let's consider an industry . For Example:
In the healthcare industry, a pressing real-life problem revolves around the early diagnosis of diabetic retinopathy, a potentially blinding complication of diabetes. The challenge lies in sifting through a vast number of retinal images to accurately identify the presence and severity of the disease, a task that is both time-consuming and requires specialized expertise. This is where specifically convolutional neural networks (CNNs), comes into play.
By training a CNN on a diverse dataset of retinal images, encompassing various stages of diabetic retinopathy, the model learns to recognize subtle patterns indicative of the disease. The automated screening process, driven by the trained CNN, holds the promise of providing rapid and accurate preliminary diagnoses, enabling healthcare professionals to identify cases that demand immediate attention.
This application not only accelerates the diagnostic process but also exemplifies how AI, through the lens of deep learning, can be a game-changer in healthcare by enhancing efficiency and improving the accuracy of disease detection, ultimately leading to better patient outcomes.
There are many such problem sets available to us! Only task which remains is to solve these smaller problems. There is no need to look for bigger picture of your imagination while such problems do exist around us.
