Example struct dataset
 +---flower_photos
 |   +---daisy
 |   +---dandelion
 |   +---roses
 |   +---sunflowers
 |   +---tulips
 |--------------------

All top subfolders of dataset catalog will use as label of categories

Example using trainer with fluent builder
 string dirDatasets = "D:\\Downloads\\flower_photos\\";

            TrainerService trainer = new TrainerService(AppContext.BaseDirectory, "flower")
                .setArchitecture(ImageClassificationTrainer.Architecture.MobilenetV2)
                .setEpoch(1000)
                .setBatchSize(5)
                .setLearningRate(0.01F)
                .setReuseTrainBottleneckCache(true)
                .setReuseValidationBottleneckCache(true)
                .setCriteriaEarlyStopping(new ImageClassificationTrainer.EarlyStopping(0.1F, 500,
                    ImageClassificationTrainer.EarlyStoppingMetric.Accuracy))
                .setPathToDataset(dirDatasets)
                .setSplitPercent(0.3F);

            trainer.onStateChanged += state => { Console.Title = $"Current Stage: {state}"; };
            trainer.onTrainMetrics += Trainer_onTrainMetrics;

            await trainer.Train();
            var _metrics = await trainer.GetMetrics();
            await trainer.SaveModel();
Example using prediction service with fluent builder
   PredictorService service = new PredictorService("D:\\flower_photos\\test_fraction\\")
                        .setPathToModel("D:\\21-01-10_flower.zip");
            service.onPrediction += prediction => Console.WriteLine(prediction);
            await service.Process();
            
/* output log with event onPrediction
