Ok, I’ll admit it, when I read or heard people throwing terms, machine learning, and deep learning, around like they mean the same thing, I was confused, as well. Wasted hours reading technical documents that were head spinning stuff.
Now I would like to deconstruct what is the difference between deep learning and machine learning in a manner that is actually comprehensible.
Table of Contents
The Basic Breakdown
The point is that in this case machine learning is the parent, and deep learning is the kid. They both fall in the field of artificial intelligence, and they are different in their work.
I gave myself a basic task of recognizing an image. In conventional ML, I needed to give the system instructions in order to know what to pay attention to, these are edges, colors, shapes. It was tedious. With deep learning? The model 2 worked it out. And that is the main distinction.
Machine learning involves using patterns to decode data through data-based algorithms to come up with decisions. You give it information, it trains, it foresaw. Simple.
Deep learning goes the extra mile as they apply the concept of neural networks that are multilayered (i.e. deep) and which mimics the way our brains process information. It’s ML on steroids, basically.
What Makes Them Different (The Stuff That Actually Matters).
Data Requirements
ML Traditional ML is more effective when working with small sets. I have created satisfactory predictive models using a small number of thousand data points. Deep learning? It’s hungry. Ravages large quantities of data to perform calculations, which by this measure means hundreds of thousands, even millions of examples.
Feature Engineering
This is when things come into interest. In ML, I took hours to manually determine which features to consider important. Testing a spam filter? I needed to make a choice: word count, special phrases, reputation of a sender matter. It’s manual work.
Deep learning models learn without being guided to do so. Give them raw data, and they make up their minds on what is important. One that means that I do not have to do as much work, but much more computing.
Computing Power
ML models can be executed on my laptop. In fact, I have fitted decision trees and random forests in a five year-old MacBook. Deep learning models? They need GPUs or TPUs. Once I attempted to use a neural network to train on my CPU, which is not a neural network capable of processing images in real time, the process would take three days.
Practical Applications (One of which is doing great)
Machine Learning in Action
When that happened to me, ML had sunk it:
Banks detect frauds via machine learning (ML) systems. They do not require the complexity of deep learning, only good pattern recognition of structured data such as the amount of transactions, place and time.
The prediction of churn among customers is fine with classical ML. To know who is about to cancel, companies take a look at purchase history, support tickets, and usage trends. I assisted in the establishment of one to a subscription service -78% on a simple random forest representation.
ML is applied to medical diagnosis tools of straightforward cases. One of my doctors has an ML system, which means that diabetes risk is predicted depending on the blood sugar level, BMI and the family history. Quick, understandable and does not use hours of processing power.
Deep Learning Dominance
When there comes complexity, deep learning comes into play:
The voice assistants Siri and Alexa are based on the deep learning. Simple voice command system – I tried to build a simple voice command system using traditional ML, terrible results. Replaced with a deep learning model which was trained on thousands of voice samples? Night and day difference.
Autopilot vehicles are operated with deep learning applied to real-time camera images. They are identifying the pedestrians, reading the road signs, and anticipating the actions of other roads. That is too complex not to be addressed by classic ML.
Generative AI such as ChatGPT or Claude (yeah, the artificial intelligence you may be using right this second) are deep learning models pure. These models comprehend the context, create human-like text and multi-lingualism. The conventional ML cannot reach this complexity.
Trendy Models You will actually meet.
Machine Learning Models
Decision Trees and Random Forests- I use them continuously. They are flowcharts, but the decisions are made on yes/no questions. Quick to learn, simple, surprisingly, and many quick to learn.
Support Vector machines (SVM) -Exceptional in classifying issues. I have constructed a simple image classifier that categorized products. Performed well using half of the labelled images (2,000).
Logistic Regression – So, do not be mislead by its name, it is a classification algorithm. Lots of binary predictions such as will this customer purchase or not are perfect. Simple, fast, interpretable.
Deep Learning Models
Convolutional Neural Networks (CNNs) – The anything-visual. I have applied ready-made CNNs in projects of facial recognition and product image recognition. They instinctively get to know how to identify edges, then shapes, and then complicated objects.
Transformers -These transformed the whole language processing. Transformers such as a GPT and BERT model. To learn about the relations between words, they use attention mechanisms even when they are quite distant in a sentence.
Recurrent Neural Networks (RNNs) These are used on sequential data such as time series or text. To forecast stock prices I took an LSTM (a variant of RNN), and used it to predict the stock price changes. It is not flawless, but it is better than the traditional forecasting techniques.
So Which One Should You Use?
My opinion on the two is presented below: begin with machine learning.
In case you have a small amount of data, you desire fast-moving solutions, or prefer to have a, well-conceived insight into precisely how your model makes decisions – you should use traditional ML. It is quicker to put in place, cheaper to operate and easier to detail to the non-technical stakeholders.
Resort to deep learning in case you are working with images, audio, video or natural language at scale. When you actually have lots of data and processing environment. Interpretability is unimportant and accuracy is valued.
I have witnessed too many individuals skipping to deep learning due to its hippier sounding and then finding it hard to overfit their small dataset. Don’t be that person.
The Real Talk
The distinction between deep learning and machine learning is not only an academic question to understand, but it impacts the choice of tools you use, the amount of funds you make, and the success of the project you are working on.
Both have their place. ML works with tabular data much more conveniently with structured data. Deep learning opens opportunities to unstructured data that appeared unattainable half a decade ago.
