What is AI?
The scope of AI is disputed: as machines become
increasingly capable, tasks considered as requiring
"intelligence" are often removed from the definition of AI, a
phenomenon known as the AI effect

What is AI?
If a computer system does something
and you think: “that was pretty smart”
-> AI

Supervised learning: x ↦ y
Examples:
● Image recognition. x = image, y = label (cat, dog, apple, ...)
● Predicting house prices. x = [neighborhood, m², ...], y = price
● Spam detection. x = email text, y = spam/not spam
● Speech recognition. x = audio, y = transcribed text

Stochastic Gradient Descent Training

At each step the gradient of the error
between prediction and label is used to
determine how to change connections
towards a smaller error.

Applying Machine Learning (ML)

The ML Surprise - Effort Allocation

1. Evaluate simple heuristics without ML first
2. Use a ML API
3. Find a pre-trained open source model
4. Finetune a pre-trained model
5. Use open source code to train a model on your data
6. Build a model from scratch
Priority list when applying ML

Deep Learning vs other approaches
● Image recognition. x = image, y = label (cat, dog, apple, ...) Visual ✅
● Speech recognition. x = audio, y = transcribed text Audio ✅
● Text classification. x = email text, y = spam/not spam NLP ✅
● Predicting house prices. x = [neighborhood, m², ...], y = price Tabular❌

Deep Learning vs other approaches
Deep Learning:
● Image recognition. x = image, y = label (cat, dog, apple, ...) Visual ✅
● Speech recognition. x = audio, y = transcribed text Audio ✅
● Text classification. x = email text, y = spam/not spam NLP ✅
Decision trees, linear models, nearest neighbour:
● Predicting house prices. x = [neighborhood, m², ...], y = price Tabular❌

Workflow for adding a ML feature
1. Define evaluation criteria and evaluation data
2. Find model with sufficient performance
3. Create container with web server, model and parameters
4. Deploy container in cloud
5. Send features over HTTP from main service
6. Receive predictions
7. ...profit $

Being productive with machine learning doesn’t
require a deep understanding of the mathematics
