Hello everybody,
today I want to note important for me details of Machine Learning.
So, the first and very important usage of PCA is visualizing data. If you have 10 dimensions, can you visualize those data? If you can I'm happy about you, but I can't. I can imagine only 1, 2, 3 D :). But w...
Hello everybody,
another interesting notice today.
Imagine following situation.
1. You have base class. Let it is called GraphX.
2. In your library you created extentions of this grap: GraphXExt1, GraphXExt2 at the same level. For example like this:
public class GraphXExt1 : PXGraphE...
Hello everybody,
Imagine following scenario. You have some code in base class, which you need to change. How to do it. For this purpose you can use PXOverride attribute.
See the following code:
public class YourExtension : PXGraphExtension<SomeBasicGraph>

Primary: Adds the Add, Delete, Fit to Screen, and Exportbuttons to the toolbar. This value is typical...
Few notes of how to debug machine learning algorithm:
Get more training examples
Try smaller sets of features
Try getting additional features
Try adding polinomial features
Try increasing lambda
Try decreasing lambda
What those trys can achieve:
fixes high variance
fixes high variance
fixes hi...
Small note of how to use more effective of Neural Networks:
1. Use different numbers of hidden layers
2. Different numbers of units per layer
3. Different types of unit
4. Different types of strengths of weight penalty
5. Different learning algorithms
Ready to take your Acumatica experience to th...
Hello everybody,
today another notice. Acumatica can provide values in two modes: merged and read-only.
So, what is merged? Imagine that user worked about the form, and made some changes at grid. Will changes apper in DB? Untill will be executed Persist, not. Data will be only in cache. Some time...
