Question

When asked about which option would generally result in a Regression Problem, we should assess the nature of the target variable in each choice.
Option 1: Predicting the specific block number (e.g., 101, 102) when estimating HDB resale flat prices. This is a discrete, ordinal or categorical target, depending on how blocks are treated, and typically approached as classification or a structured prediction problem rather than regression.
Option 2: Predicting the Car Price in Singapore Dollars (e.g., $120,500, $155,000) for a used COE car. Here the target is a continuous numeric value representing price, which aligns with regression since we’re estimating a quantity on a continuous scale with real-valued outputs.
Option 3: Predicting the type of cuisine (e.g., Chinese, Malay, Indian) a customer prefers in a hawker centre. This is a categorical label problem, i.e., classification, not regression.
Option 4: Predicting a bank account number based on customer characteristics. While numbers are numeric, account numbers are identifiers rather than quantities to be predicted as a meaningful numeric measure; predicting an ID-like string is not standard regression and is more akin to sequence or pattern prediction, often treated as a specialized classification or generation task rather than regression.
In summary, only Option 2 involves forecasting a continuous numeric value suitable for regression techniques, whereas the others involve categorical, discrete, or identifier targets that fall outside the classic regression framework.
