      <description>&lt;p&gt;Assume we start on one huge area and want to build a model to suggest whether how much for each point of latlon recommended to be placed with new signal transmitter.&lt;/p&gt;

&lt;p&gt;1st step : create all possible latlon within border area (100m grid)&lt;/p&gt;

&lt;p&gt;2nd step : create all relevant features like&lt;/p&gt;

&lt;p&gt;-closest existing transmitter distance -current signal level for the point (at this sample latlon) -how much use using the existing transmitter that closest to this point (at this sample latlon) -number of users using signal at this current point&lt;/p&gt;

&lt;p&gt;Questions &lt;/p&gt;

&lt;p&gt;1.If I choose NNet model, I need to come up with score function to calculate suitable score for each feature vector. because it is required to train with the model since its supervised model, how can I find the suitable score function? and do I need to consider outlier at particular feature when find the score function.&lt;/p&gt;

&lt;p&gt;2.If I can have labeled data, what is the benefit of ML model since I can use this score function with automated traditional software to generate the rank of point list.&lt;/p&gt;

&lt;p&gt;3.If I use unsupervised method, it will group only similar characteristic point based on features, but how to rank this point, somehow, I need to educate model that each feature, the higher value means good, or higher value means bad right?&lt;/p&gt;

&lt;p&gt;4.any recommendation or any better model choice?&lt;/p&gt;

&lt;p&gt;I have tried to outline toe step, but I have question since the approach does not sound to outperform traditional automated software.&lt;/p&gt;
