What's new

• Important: Improved calculaion of uncertainty over time-parametrized operators
• Important: Fixed issue with incorrectly evaluation of time-based operators for states not ending on 0 (e.g. [-5min to -2min])
• Refactoring of UncertaintyEvaluator interface (now, classes that implement it have to implement also time parametrized operators)
• Fixed cold start problem in evaluation of temporal operators (the certainty decreases, as the missing values are nulls)

Download link: heartdroid-1.2.0.jar

What's new

• Important: The ambiguous values are retained in the memory until the reasoning process is over. This allows to capure current state during the reasoning process.
• Important: The time-based operators search for the historical values based on state timestamp, not value timestamp
• Fixed issues with callbacks not working on Android
• Fixed issues with time-based operators not including current state in evaluation

Download link: heartdroid-1.1.0.jar

What's new

• Important: The way the inference mechanism selects the rules to fire changed. In case of uncertainty evaluation, in case of fire all, all rules that satisfies the satisfiability threshold are added and executed in conflict set.
• Missing fire last conflict set resolution mechanism added
• Added lacking mathematical operators (sin(), cos(), pow(), factorial(), etc.)
• Fixed issues with Java 8 API on Android

Download link: heartdroid-1.0.1.jar

What's new

• Fixed major bug, that caused incorrect evaluation of ambiguous values assignment during inference process
• Fixed major bug, that prevented from using cllbacks when using HeaRTDroid as a JAR library
• Interfaces for Actions and Callbacks were changed to better support this mechanisms purposes
• Builders of HMR+ elements were added that allows to create Attributes, Types, etc. by providing HMR+ code in constructors
