Hey! Finished Lesson 8 of the first part of fastai course. I was thinking of trying to tackle a problem in which I need to predict a number given a text.
So First I decided to create an LM suitable for this task
dls = TextDataLoaders.from_df(df, text_col='text', is_lm=True)
Then I decided to create the learner and start the training
learn = language_model_learner(dls, AWD_LSTM, drop_mult=0.3,metrics=[accuracy, Perplexity()]).to_fp16() learn.fine_tune(1, 2e-2)
This gave me an accuracy of 30% on predicting the following word. Pretty good!
But now I’m quite stuck…
I started looking at the example given in the class:
class_data = DataBlock(blocks=(TextBlock.from_df('text', vocab=dls.vocab), CategoryBlock),get_x=ColReader('text'), get_y=ColReader('target'), splitter=RandomSplitter(0.2))
dls_class = class_data.dataloaders(df)
learn2 = text_classifier_learner(dls_class, AWD_LSTM, drop_mult=0.5, metrics=accuracy).to_fp16()
The problem is that this only works for classification, I need to modify it to work with regression.
Thanks in advance!
