We will use the dataset which is available on Kaggle for sentiment analysis, which consists of a sentence and its respective sentiment as a target variable. This dataset contains 3 separate files named train.txt, test.txt and val.txt. This is why we need a process that makes the computers understand the Natural Language as we humans do, and this is what we call Natural Language Processing(NLP). And, as we know Sentiment Analysis is a sub-field of NLP and with the help of machine learning techniques, it tries to identify and extract the insights. We can change the interval of evaluation by changing the logging_steps argument in TrainingArguments. In addition to the default training and validation loss metrics, we also get additional metrics which we had defined in the compute_metric function earlier.

Based on how you create the tokens, they may consist of words, emoticons, hashtags, links, or even individual characters. A basic way of breaking language into tokens is by splitting the text based on whitespace and punctuation. Language in its original form cannot be accurately processed by a machine, so you need to process the language to make it easier for the machine to understand. The first part of making sense of the data is through a process called tokenization, or splitting strings into smaller parts called tokens.
