Richard Roberts 5367e5a157 All std::map<Symbol,T> are now SymbolMap<T>, which is just a thin wrapper around std::map. at(Key) is used instead of first checking with find when an exception should be thrown for non-existent keys. This does not change any behavior or timing currently. This check-in also includes some functions in BayesTree for gathering clique statistics. 2010-01-22 04:41:40 +00:00

Michael Kaess 0286bc27eb removePath mostly working 2009-11-21 03:38:13 +00:00
Frank Dellaert f40182518a size() now returns correct nr. of cliques, not number of keys 2009-11-18 18:05:12 +00:00
Frank Dellaert 03f865d4b1 Used typedefs with similar naming convention. 2009-11-12 18:33:14 +00:00
Alex Cunningham c7b86cec97 Renamed ConditionalGaussian -> GaussianConditional 2009-11-12 16:41:18 +00:00
Alex Cunningham 77a1754b69 Renamed LinearFactor -> GaussianFactor, LinearFactorGraph -> GaussianFactorGraph 2009-11-12 16:16:32 +00:00
Frank Dellaert 1ae6bb4030 Added push_fron convenience method to add ConditionalGaussians into a Bayes net with much less clutter. Modernized some very old tests in the process. 2009-11-12 06:09:03 +00:00
Frank Dellaert f677341108 Moved inference methods to new compilation unit. Added [factor], and [marginalize] now returns a factor graph. 2009-11-12 04:56:30 +00:00
Frank Dellaert a3de1964d7 BIG CHANGE:
1) eliminate methods no longer return a shared pointer. Shared pointers are good for Factors and Conditionals (which are also non-copyable), because these are often passed around under the hood. However, a BayesNet is simple a list of shared pointers and hence does not cost a lot to return as an object (which is compiler-optimized anyway: there is no copy). So, the signature of all eliminate methods changed to simply return a BayesNet<> object (not a shared pointer).

2) GaussianBayesNet::optimize is now replaced by optimize(GaussianBayesNet) and returns a VectorConfig and not a shared pointer

3) GaussianBayesNet and SymbolicBayesNet are now simply typedefs, not derived classes. This is desirable because the BayesTree class uses templated methods that return BayesNet<Conditional>, not a specific BayesNet derived class.

Frank Dellaert dd1b023ca9 Fixed special case for root 2009-11-09 04:45:38 +00:00
Frank Dellaert cc22e82ca6 Joint densities (covariances) now done. Was exceedingly easy :-) 2009-11-09 00:13:44 +00:00
Frank Dellaert 86173b66af Clique marginal and dramatically simplified single variable marginal. 2009-11-08 22:51:12 +00:00
Frank Dellaert 58007a8167 Working recursive (but not cached) shortcut. 2009-11-08 04:41:01 +00:00
Frank Dellaert f5d186522e Standardized on new shared_ptr naming convention 2009-11-07 17:24:05 +00:00
Frank Dellaert d9289d14b3 marginals on any scalar now work 2009-11-05 08:06:32 +00:00

Frank Dellaert cabcda5a96 marginal compiles and runs for frontal node in clique 2009-11-05 06:30:50 +00:00
Frank Dellaert 11fcd5a69d KISS: just a map of pointers in BayesTree now 2009-11-05 05:29:47 +00:00
Frank Dellaert 4865edb883 Removed debug code, added marginal function 2009-11-04 03:22:29 +00:00
Frank Dellaert e9d942f81e BayesNet is now list-based for fast bi-directional access
SLOW O(n) random access operator[key] provided 
(should maybe be called [at] as it does bounds checking)
I also fixed a bug in equals.
2009-11-03 06:29:56 +00:00
Frank Dellaert eab038651e Renamed BayesNet::insert -> push_back. BayesTree now uses Bayes nets as nodes. 2009-11-02 05:17:44 +00:00
Frank Dellaert a8d267c4ca Small change necessitating lots of edits: Conditionals now include key of random variable
This simplifies Bayes nets quite a bit. Also created a Conditional base class, derived classes ConditionalGaussian and SymbolicConditional
Finally, some changes were needed because I moved some headers to .cpp
2009-11-02 03:50:30 +00:00
Frank Dellaert 943b692a6b BIG CHANGE: I got rid of the BayesChain/ChordalBayesNet classes and we now simply have a BayesNet class. It will just happen to be chordal when it is the result of an elimination. This will simplify a lot of things.
The main renaming that happened is

BayesChain -> BayesNet
ChordalBayesNet -> GaussianBayesNet == BayesNet<ConditionalGaussian>
SymbolicBayesChain -> SymbolicBayesNet == BayesNet<SymbolicConditional>
