You are clustering a collection of 10,000 news articles based on their TF-IDF (term frequency-inverse document frequency) vectors, resulting in a sparse, high-dimensional representation of the documents. You are using K-Means and GMMs to identify thematic clusters such as sports, politics, and technology. Which of the following statements are true in this context?

You are building a regression model to predict house prices based on features such as size, age, number of rooms, and location. You are considering two feature transformation techniques: Principal Component Analysis (PCA)} to reduce dimensionality. Polynomial feature expansion} to capture nonlinear relationships. Which of the following statements are true in this scenario?

You are analyzing a high-dimensional dataset (d = 100) with the following characteristics: There are three underlying clusters with very different sizes (one large, two small). The data contains moderate Gaussian noise. The clusters are roughly spherical in their original feature space You are tasked with selecting a clustering method that is robust in high-dimensional, noisy, andimbalanced settings. Which of the following statements are true in this scenario?
