Which of the following NLP tasks can benefit from BERT-based models?*Stock market predictionSpeech synthesisSentiment analysisImage recognition

BERT-based models are primarily used for natural language processing tasks. Among the options provided:

1. Stock market prediction: This is not a typical application for BERT-based models. While it's possible to use NLP techniques to analyze news articles or social media posts that might impact stock prices, the prediction of stock market movements is a complex task that involves numerous variables beyond just text data.

2. Speech synthesis: BERT is not typically used for speech synthesis. Speech synthesis, or text-to-speech, is the process of creating spoken language from written text, which is a different kind of task.

3. Sentiment analysis: Yes, BERT can be very useful for sentiment analysis. Sentiment analysis involves determining the sentiment expressed in a piece of text, which is a task that BERT is well-suited for.

4. Image recognition: BERT is not used for image recognition. BERT is a model for text processing, while image recognition is a task typically handled by convolutional neural networks (CNNs).

So, among the given options, BERT-based models can benefit Sentiment Analysis.
