 # Magic: The Gathering Card Detection Model
 
 This is a fork of [Yolo-v3 and Yolo-v2 for Windows and Linux by AlexeyAB](https://github.com/AlexeyAB/darknet#how-to-compile-on-linux) for creating a custom model for [My MTG card detection project](https://github.com/hj3yoo/MTGCardDetector). 
 
+## Day ~0: Sep 6th, 2018
+---------------------
+
+Uploading all the progresses on the model training for the last few days.
+
+First batch of model training is completed, where I used ~40,000 generated images of MTG cards laid out in one of the pre-defined pattern.

+
+After 5000 training epochs, the model got 88% validation accuracy on the generated test set.

+
+However, there are some blind spots on the model, notably:
+
+- Fails to spot some of the obscured cards, where only a fraction of them are shown.
+- Fairly fragile against any glaring or light variations. 
+- Cannot detect any skewed cards.
+
+Example of bad detections:

+
+The second and third problems should easily be solved by further augmenting the dataset with random lighting and image skew. I'll have to think more about the first problem, though.
