Q1. Coding in Python using explode
Ans. 
Explode function in Python is used to split a string into a list of strings based on a specified delimiter.
• Use the explode function from the pandas library to split a string column into multiple rows in a DataFrame.

• Specify the delimiter parameter to define how the string should be split.

• For example, df['column'].str.split('delimiter').explode() will split the strings in 'column' based on 'delimiter' and create a new ro

Q1. What is F Score
Ans. 
F Score is a measure of a test's accuracy that considers both the precision and recall of the test.
• F Score is calculated using the formula: 2 * (precision * recall) / (precision + recall)

• It is used in binary classification tasks to balance precision and recall.

• A high F Score indicates a model with both high precision and high recall.

Q3. What is cosine similarity
Ans. 
Cosine similarity is a measure of similarity between two non-zero vectors of an inner product space.
• It measures the cosine of the angle between two vectors.

• Values range from -1 (completely opposite) to 1 (identical), with 0 indicating orthogonality.

• Commonly used in text mining for document similarity and recommendation systems.

Q4. How do you generate embeddings
Ans. 
Embeddings are generated by converting words or entities into numerical vectors in a high-dimensional space.
• Use pre-trained word embeddings like Word2Vec, GloVe, or FastText

• Train your own embeddings using algorithms like Word2Vec, GloVe, or FastText on a large corpus of text data

• Fine-tune pre-trained embeddings on domain-specific data to improve performance

Q1. What is p value? What is spacy, NLP, NER model?
Ans. 
p value is a statistical measure that helps determine the significance of a hypothesis test.
• p value is the probability of obtaining a result as extreme or more extreme than the observed result, assuming the null hypothesis is true.

• A p value of less than 0.05 is considered statistically significant.

• Spacy is an open-source software library for advanced natural language processing (NLP).

• NLP is a field of study that focuse...read more

Q2. What is lamda function in python?
Ans. 
Lambda function is an anonymous function in Python that can take any number of arguments and can only have one expression.
• Lambda functions are defined using the keyword 'lambda'.

• They are commonly used with built-in functions like filter(), map(), and reduce().

• Lambda functions can be used to create small, throwaway functions that are not needed elsewhere in the code.

• They are often used to write more concise and readable...read more
