Machine Learning vs Deep Learning
TLDRThe video explains the difference between machine learning and deep learning using pizza as an analogy. It first maps out the hierarchy with AI at the top, then machine learning, neural networks, and finally deep learning. It then builds a basic machine learning model with 3 inputs to determine if pizza should be ordered. Deep learning is distinguished by having more than 3 layers, not needing structured labeled data from humans, and using techniques like backpropagation. The video concludes that deep learning and machine learning are subfields of AI with neural networks at their core, but deep learning has more layers and doesn't require human supervision of data.
Takeaways
- 😀 Machine learning uses structured labeled data to make predictions, while deep learning can work with raw unstructured data
- 🍕 The example uses ordering pizza to explain how a simple machine learning model with weighted inputs makes decisions
- 🌿 Deep learning neural networks have more layers (3+) between input and output compared to machine learning
- 🧠 Deep learning discovers patterns itself from raw data without human supervision (unsupervised learning)
- 🔙 Deep learning models can be improved through backpropagation which attributes and adjusts errors
- 🚀 Machine learning depends more on humans to label features distinguishing data, known as supervised learning
- 📈 Deep learning is a subset of machine learning, which is a subset of AI (artificial intelligence)

- 🍔 The example uses images of different fast food to show how deep learning can cluster unstructured data
- 👍 The presenter summarizes by saying deep learning needs no labeled dataset and can have more hidden layers
Q & A
What are the main components that make up AI?
-The main components of AI are machine learning (ML) and neural networks (NN), which together make up deep learning (DL).
What are the key differences between machine learning and deep learning?
-The key differences are: 1) Deep learning uses neural networks with more than 3 layers while machine learning can use any type of model, and 2) Machine learning relies more on human-labeled data while deep learning can work with raw, unstructured data.
What is an activation function in machine learning?
-An activation function in machine learning calculates the output of a node or neuron given inputs and weights. It determines if a neuron should be activated or not.
What does supervised learning mean?
-Supervised learning is when humans label and organize the data that is fed into machine learning models, guiding the learning process.
What does unsupervised learning mean?
-Unsupervised learning is when machine learning models work with unlabeled, unstructured data and find patterns without human intervention.
What is backpropagation in neural networks?
-Backpropagation is the process of calculating and attributing error in neural networks, flowing from output to input. It helps adjust the model by propagating these error signals backwards.
What were the 3 inputs in the pizza ordering example?
-The 3 inputs were: 1) Will it save time? 2) Will I lose weight? and 3) Will it save money?
How were the inputs weighted in the example?
-The 'save time' input was weighted 5, the 'lose weight' input was weighted 3, and the 'save money' input was weighted 2.
What was the threshold value in the example?
-The threshold value was 5. The sum of the weighted inputs had to exceed 5 for the model to predict a pizza order.
What activation function was used in the example?
-The specific activation function was not stated. The example calculated the weighted sum of inputs and compared to a threshold.

😊 Defining Machine Learning vs Deep Learning with a Pizza Ordering Example
The paragraph explains the difference between machine learning and deep learning using a pizza ordering decision example. It defines machine learning models as leveraging labeled data and weights to make predictions based on inputs. The pizza ordering inputs consider time savings, weight loss, and cost savings. Deep learning differs in that it consists of neural networks with more than 3 layers and can work with unstructured, unlabeled data to automatically determine distinguishing features between inputs.
😋 Comparing Classical Machine Learning and Deep Learning
This paragraph contrasts classical machine learning and deep learning. Classical machine learning relies more on human experts to label data features and hierarchies, known as supervised learning. Deep learning can directly process raw unstructured data like images to determine distinguishing features without human intervention (unsupervised learning). Most deep neural networks utilize feedforward and backpropagation techniques to improve learning.
