  • Probabilistic Graphical Models 10-708, Spring 2017

    https://www.cs.cmu.edu/~epxing/Class/10708-17/slides/lecture1-Introduction.pdf

    Computational and CS orientated => DK and NF's book

    Statistical and easier one => Jordan's book

    MLAPP => also a good book

    HWs => Theory, algorithm design and implementation. Very heavy.

    N copies of data.

    subscript means the dims of features.

     

     bottom right figures

    a given presentation + inference => enough for some tasks

    learn a representation => a more adv. task

    M* = argmax (m in M) F(D;m)

    M*: best representation

    m: one representation

    F: score function

    D: data

     

     one simple case: every random variable X_n is binary: X_n in {0,1}

    O(exp(n)) => bad algorithm

    ↓↓↓↓↓↓↓↓↓↓(invite a biologist)↓↓↓↓↓↓↓↓↓↓↓

    categorize

    add pathways

     

    18 vs 2^8

     

    A factorization rule. two resources of variables.

     

     

     

    PGM => conditional distribution

    GM => pm.Deterministic

     If I have P(A,B), how to proof A is independent of B?

    Method 1: defactorize P(A,B) = P(A)*P(B)

    Method 2: build a graph like the one above, and A and B are automatically independent

     

    Yellow ⊥  Orange | Graph

    the yellow node is only linked to its parents, children, and children's coparents (greeen nodes)

    ⊥: indenpendency

     

     



     

    DARPA grand challenge

    NLP

    biostats
