2022-07-07

• fairly major changes to (extended) kalman filtering sections (introduced Gaussian Joint/Condition abstractions)
• cleaned up material (eg notation, proofs) related to linear gaussian systems
• fixed more typos
• latexified more figures

2022-07-01

• more progress on refining SSM modeling and inference
• more typos
• more latexifying

2022-06-28

• Major refactoring: split the chapter on message passing into 2 chapters, one focused on state space models (HMM, KF) and one for general graphs (LBP, JTA).
• Moved JTA to supplementary.
• Moved a lot of the material about SSM back from supplementary into main.
• Fixed more typos.
• Updated figure links to point to https://github.com/probml/pyprobml/blob/master/notebooks.md, so we no longer need to auto-generate figure names or use firestore.

2022-06-24

• moved some more material (eg on HMM, LDS) back from supplementary into main
• added more latexified figures
• fixed more typos
• cleaned up mixFA and PPCA sections
• added stuff on discriminative GMMs

2022-06-20

• moved some of the content on MVNs (eg conjugate analysis) back from supplementary into main text
• add latexified versions of some figures (eg in GP chapter)
• fix more typos

2022-06-17

• remove list of figures (LOF) at the start, which wastes 50 pages (now under 1300 :)
• fix some typos

2022-06-11

• update diffusion models chapter
• fixed >300 typos / errors (mostly found by John Fearns)
• other tweaks

2022-05-18

• URLs in the figure captions now refer to the name of the file, such as mc_estimate_pi.ipynb , not https://code.probml.ai/book2/10.1. Clicking on the link will open that file directly in colab without us having to keep backend firebase up to date as things change. As a consequence, book2.pdf has a list of figures which increases the page count by about 30. This is just a temporary measure to faciliate processing in the backend; this will be removed for camera ready version.
• Added TOC, footer, and line numbering to supp2 (previously accidently omitted)
• Made some tweaks to the ADVI / Gaussian VI section, to add place holder figures for future demos that are being written.
• Tweaked the LKJ section.
• Moved online VI to supplement.
• Moved some common distributions (eg Pareto) from supplement to main text, to reduce cross reference issues.
• Fixed some typos.

2022-05-17

• 35 pages shorter, by moving even more content related to SSMs (models, inference, PF) to the online supplement
• changed LDS notation to "east coast" tradition (F/H, not A/C) for consistency with the nonlinear case
• fixed some typos
• added a few more figures
• cleaned up ADF sections

2022-05-02

• This version now supports cross references from the main book to supplementary material.
• Fixes all the broken cross references in the main book. (Supplementary still has broken xrefs.)
• Fixes some other typos.
