+## This course is broad!
+- Each module could be its own course
+    - We won't be able to go super deep
+    - You will probably get lost
+- Our goal: broad survey of multiple areas
+    - Lightning tour, focus on high points
+
+>  Hope: find a few things that interest you
+
+## This course is technical!
+- Approach each topic from a rigorous point of view
+- Parts of "data science" with **provable guarantees**
+- This is not a "theory course", but...

 # Differential privacy
 
+##
+
+![](images/privacy.png)
+
 ## A mathematically solid definition of privacy
 - Simple and clean formal property
 - Satisfied by many algorithms
 - Degrades gracefully under composition
 
-# Applied crypto
-
-## Computing in an untrusted world
-- Proving you know something without revealing it
-- Certifying that you did a computation correctly
-- Computing on encrypted data, without decryption
-- Computing joint answer without revealing your data
-
-# Language-based security
-
-## Ensure security by construction
-- Programming languages for security
-- Compiler checks that programs are secure
-- Information flow, privacy, cryptography, ...
-
 # Adversarial machine learning
 
+##
+
+![](images/aml.jpg)
+
 ## Manipulating ML systems
 - Crafting examples to fool ML systems
 - Messing with training data
 - Extracting training information
 
+# Applied crypto
+
+##
+
+![](images/crypto-ml.png)
+
+## Crypto in data science
+- Learning models without raw access to private data
+- Collecting analytics data privately, at scale
+- Side channels and implementation issues
+- Verifiable execution of ML models
+- Other topics (e.g., model watermarking)
+
+# Algorithmic fairness
+
+##
+
+![](images/fairness.png)
+
+## When is a program "fair"?
+- Individual and group fairness
+- Inherent tradeoffs and challenges
+- Fairness in unsupervised learning
+- Fairness and causal inference
+
+# PL and verification
+
+##
+
+![](images/pl-verif.png)

+## Proving correctness
+- Programming languages for security and privacy
+- Interpreting neural networks and ML models
+- Verifying properties of neural networks

+## Lecture schedule
+- First ten weeks: **lectures MWF**
+    - Intensive lectures, get you up to speed
+    - M: I will present
+    - WF: You will present
+- Last five weeks: **no lectures**
+    - Intensive work on projects

 ## Paper presentations
-- Sign up to lead a discussion on one paper
-- Suggested topic, papers, and schedule on website
-- Before each presentation:
-    - I will send out brief questions
-    - Please email me brief answers
+- In pairs, lead a discussion on group of papers
+    - See website for [detailed instructions](https://pages.cs.wisc.edu/~justhsu/teaching/current/cs763/assignments/presentations/jjj)
