Re: [Pharo-dev] Machine Learning in Pharo

by Oleks

Hello PolyMath contains packages that implement different optimization and statistical analysis algorithms that are used in machine learning (like linear regression, least squares, hill climbing and so on). It also has an implementation of a genetic algorithm. And there are several implementations of neural networks (this one is cool: http://smalltalkhub.com/#!/~abergel/NeuralNetworks <http://smalltalkhub.com/#!/~abergel/NeuralNetworks> ). I am working on my own implementation of neural nets ( http://smalltalkhub.com/#!/~Oleks/NeuralNetwork <http://smalltalkhub.com/#!/~Oleks/NeuralNetwork> ), you can read this, if you are interested: https://medium.com/towards-data-science/single-layer-perceptron-in-pharo-5b… <https://medium.com/towards-data-science/single-layer-perceptron-in-pharo-5b…> . I didn't hear of any other ML algorithms implemented in Pharo, but maybe you will find something here: http://smalltalkhub.com/list <http://smalltalkhub.com/list> -- View this message in context: http://forum.world.st/Machine-Learning-in-Pharo-tp4941872p4941877.html Sent from the Pharo Smalltalk Developers mailing list archive at Nabble.com.

For example in Calypso there is ShowClassRefsCommand which is shown as toolbar button in both system and method browsers. But this command is in ClassCommand hierarchy because it operates on collection of classes. We can lookup both MethodCommands and ClassCommands in method browser. But then we will have a lot of commands which we do not need in method browser. Another example is "browse" command which is accessed by cmd+b and from context menu of any browser pane. Here is how they all connected to Calypso browsers: ClyShowClassRefCommand class>>systemBrowserToolbarActivator <commandActivator> ^ClyToolbarCommandActivator byItemOf: ClyButtonToolbarGroup for: ClyClassSystemBrowserContext ClyShowClassRefCommand class>methodBrowserToolbarActivator <commandActivator> ^ClyToolbarCommandActivator byItemOf: ClyButtonToolbarGroup for: ClyMethodBrowserContext ClySpawnSystemBrowserCommand class>>browserShortcutActivator <commandActivator> ^CmdShortcutCommandActivator by: $b meta for: ClyBrowserContext ClySpawnSystemBrowserCommand class>>browserMenuActivator <commandActivator> ^CmdContextMenuCommandActivator byRootGroupItemFor: ClyBrowserContext (ClyBrowserContext is superclass of any Calypso browser contexts)

For example there is enhancement of Epicea. But Epicea was not in Pharo 5. Thus, enhancements of Epicea should not get in the changelog. Only "Integration of Epicea" should be in the changelog.

Security in the image

by LaeMing

Hi, I am fishing about for an environment to try to develop a simple virtual world system in (yes, I'm aware of croquet/cobolt!). In a smalltalk-like environment, that might conceivably involve inviting multiple people into the 'image' where the world is hosted to interact with objects within it (if I was to use a smalltalk, it would want it to interleave the entire system, not just host it on top.) What sort of security implications might that have and are there any current solutions to a multi-user single-image situation? -- View this message in context: http://forum.world.st/Security-in-the-image-tp4941857.html Sent from the Pharo Smalltalk Developers mailing list archive at Nabble.com.
