I had earlier used a baseline solution without augmentations and it was able to score <strong>0.78X</strong> , I applied Audio Data Augmentations and simplified model architecture(removed some dense layers) and for the same backbone architecture I was able to get a score of <strong>0.83X</strong> , that too for only after training for single fold , I added some dense layers with augmentations and the score dropped to <strong>0.78X</strong> again , so not only using augmentations but also using simple architecture is the key to place well in this comp.</p>\n<p><strong>PS: I am yet to try more ideas for this competition😄</strong></p>",
