Add LICENSE file via addalicense.com	Goran Gligorin	More...				over 12 years ago
Finished implementation for my thesis.	Goran Gligorin	More...				over 14 years ago
Added bias svd support to SvdBoostedKnn. Added CLI switches for SvdBoostedKnn. I'm roughly finished with what's needed for my thesis. Code still needs a lot of polish for actual use.	Goran Gligorin	More...				over 14 years ago
Initial implementation of kNN recommendation system boosted by SVD and some other changes.	Goran Gligorin	More...				over 14 years ago
Move a bit more code to RecommendationSystem.Svd.Foundation.	Goran Gligorin	More...				over 14 years ago
Reimplemented saving and loading models. Lots of changes to RecommendationSystem.SimpleSvd and RecommendationSystem.Svd.Foundation. Reimplemented BiasBins functionality. A lot of other changes and improvements to make everything work.	Goran Gligorin	More...				over 14 years ago
Some extra renaming in RecommendationSystem.SimpleSvd.	Goran Gligorin	More...				over 14 years ago
Added a project for a new type of a recommendation system.	Goran Gligorin	More...				over 14 years ago
Extracted kNN foundations from RecommendationSystem.SimpleKnn to RecommendationSystem.Knn.Foundation.	Goran Gligorin	More...				over 14 years ago
Added a new project RecommendationSystem.Knn.Foundation.	Goran Gligorin	More...				over 14 years ago
Ranamed RecommendationSystem.Knn to RecommendationSystem.SimpleKnn.	Goran Gligorin	More...				over 14 years ago
Rename RecommendationSystem.Simple to RecommendationSystem.Naive. Renamed RecommendationSystem.MatrixFactorization to RecommendationSystem.SimpleSvd. Extracted foundations of RecommendationSystem.SimpleSvd to RecommendationSystem.Svd.Foundations.	Goran Gligorin	More...				over 14 years ago
Moved IntersectSorted extension to RecommendationSystem.Knn.	Goran Gligorin	More...				over 14 years ago
Added support for Bias Bins to SVD. Implemented CLI switches for building SVD models. Implemented SVD testing interface.	Goran Gligorin	More...				over 14 years ago
Added a new layer in recommendation generation so it is not necessary to use a rating aggregator. RatingAggregationRecommendationGenerator now uses rating aggregators the same way they where used before. FifthsRecommendationGenerator and EqualDescentRecommendationGenerator are new type of recommendation generators. Added Pearson and Cosine similarity estimators that base similarity on all the artists between the twu users instead of just on those they have in common. Added a by-rating RMSE calculations in KnnTester and added BIAS calculations. Fixed a bug in the convergence condition in SvdTrainerBase. Changed default values for TrainingParameters.	Goran Gligorin	More...				over 14 years ago
Added the DefaultRating property to KnnRecommender which is used when the artist is not in the recommendation set generated by a kNN recommender.	Goran Gligorin	More...				over 14 years ago
Implemented a way to save and load SVD models.	Goran Gligorin	More...				over 14 years ago
Put up the scaffolding for SVD recommendation systems.	Goran Gligorin	More...				over 14 years ago
Minor changes.	Goran Gligorin	More...				over 14 years ago
Fixed a bug where Simple tests would fail because the fileWriter was not initialized.	Goran Gligorin	More...				over 14 years ago
Tiny code cleaning.	Goran Gligorin	More...				over 14 years ago
Implemented multithreading on a lower level of running tests. This allows for multithreaded running of one test. Separate tests are now back to running consecutively.	Goran Gligorin	More...				over 14 years ago
Fixed a tiny bug.	Goran Gligorin	More...				over 14 years ago
Added threading support for running multiple tests at the same time. This is using SmartThreadPool.dll.	Goran Gligorin	More...				over 14 years ago
Implemented the IKnnRecommendationSystem and a lot of changes in this commit are a result of making it work in the architecture and at a reasnoble speed. Changed RecommendationSystem.Knn and RecommendationSystem.MatrixFactorization to class libraries as that's what they really are. Added kNN tests to RecommendationSystem.QualityTesting. Multiple tests can be run one after another. Added switches to RecommendationSystem.QualityTesting so I can run a particular test without having to change the code. Lots of other improvements.	Goran Gligorin	More...				over 14 years ago
Added 3 very simple recommendation systems to use for comparison with Knn and MatrixFactorization. Added QualityTesting project which will run all the quality tests for Knn and MatrixFactorization recommendation systems with their variations.	Goran Gligorin	More...				over 14 years ago
Added weights to ContentKnnRecommender for rating similarity and content similarity. Also added weight normalization in ContentKnnRecommender and ContentSimilarityEstimator.	Goran Gligorin	More...				over 14 years ago
Implemented user similarity calculation that includes users' data like gender, county and age.	Goran Gligorin	More...				over 14 years ago
Add a functionality to split data into train and test sets.	Goran Gligorin	More...				over 14 years ago
Reimplemented RecommendationSystem.Knn so it now uses RecommendationSystem.Data. Add RecommendationSystem project which defines the architecture.	Goran Gligorin	More...				over 14 years ago
