Tweets disaster type classification model

This model was trained from part of Disaster Tweet Corpus 2020 (Analysis of Filtering Models for Disaster-Related Tweets, Wiegmann,M. et al, 2020) dataset It achieves the following results on the evaluation set:

• Train Loss: 0.0875
• Train Accuracy: 0.8783
• Validation Loss: 0.2980
• Validation Accuracy: 0.8133
• Epoch: 5

Model description

Labels <br> disease --- 1 <br> earthquake --- 2 <br> flood --- 3 <br> hurricane & tornado --- 4 <br> wildfire --- 5 <br> industrial accident --- 6 <br> societal crime --- 7 <br> transportation accident --- 8 <br> meteor crash --- 9 <br> haze --- 0

Intended uses & limitation

This model is able to detect 10 different type of disaster (nature and human-made), but it shows problem to detect the type 0 disaster due to the insignificant tweets and similarity to type 5 in the training dataset

Training hyperparameters

The following hyperparameters were used during training:

• optimizer: <br> batch_size = 16 <br> num_epochs = 5 <br> batches_per_epoch = len(tokenized_tweet["train"])//batch_size <br> total_train_steps = int(batches_per_epoch * num_epochs) <br> optimizer, schedule = create_optimizer(init_lr=2e-5, num_warmup_steps=0, num_train_steps=total_train_steps)
• training_precision: float32

Framework versions

• Transformers 4.16.2
• TensorFlow 2.9.2
