Q3. Model Evaluation technique
Ans. 
Model evaluation techniques are used to assess the performance of a machine learning model.
• Common techniques include cross-validation, holdout validation, and bootstrap validation.

• Metrics such as accuracy, precision, recall, and F1 score can be used to evaluate model performance.

• Visualizations such as confusion matrices and ROC curves can also aid in model evaluation.

• It is important to use multiple evaluation technique...read more

Q1. What is overfitting and underfitting
Ans. 
Overfitting occurs when a model learns the training data too well, leading to poor performance on new data. Underfitting occurs when a model is too simple to capture the underlying patterns in the data.
• Overfitting: Model is too complex, fits noise in the training data, performs poorly on new data

• Underfitting: Model is too simple, fails to capture underlying patterns in the data, performs poorly on both training and new...read more

Q2. What are LLM Models
Ans. 
LLM models, or Language Model Models, are a type of machine learning model that focuses on predicting the next word in a sequence of words.
• LLM models are commonly used in natural language processing tasks such as text generation, machine translation, and speech recognition.

• They are trained on large amounts of text data to learn the relationships between words and predict the most likely next word in a given context.

• Exa...read more
