### Data Distribution
Data has been downloaded with the help of [gi2ds](https://github.com/toffebjorkskog/ml-tools/blob/master/gi2ds.md)

Training set: 11524

Validation set: 2881


### Model
Resnet-50


### Data Augmentations
The following data augmentation has been applied to increase the no of images in the training set

1.  Flip horizontal
2.  Lighting
3.  Zooming
4.  Warping

### Confusion Matrix
![Confusion matrix](https://github.com/anubhavmaity/Sports-Type-Classifier/blob/master/readme_images/sports_confusion_matrix.png)

Pair of confused categories with minimum value of 2

[('motogp', 'formula1', 5),

('badminton', 'tennis', 4),

('weight_lifting', 'wrestling', 3),

('wrestling', 'wwe', 3),

('badminton', 'table_tennis', 2),

('basketball', 'volleyball', 2),

('boxing', 'wrestling', 2),

('hockey', 'ice_hockey', 2),

('kabaddi', 'hockey', 2),

('tennis', 'table_tennis', 2),

('weight_lifting', 'wwe', 2),

('wrestling', 'kabaddi', 2)]
 

### Sample Images from the confused categories:
For some images you can see the prediction is correct but the manual labelling was done wrong. This shows the CNN are less susceptible to human mistakes.
