BMAT Technology & Digital Applications 3

Question 1

Which branch of artificial intelligence trains models by rewarding desired outputs and penalizing undesired ones through environmental interaction?

Accepted Answer

Reinforcement learning

Answer

Reinforcement learning uses a reward-penalty signal from the environment to iteratively improve an agent's decision-making policy.

Question 2

A hospital digitizes pathology slides for remote review. The resulting files are termed:

Accepted Answer

Whole slide images (WSI)

Answer

Whole slide images (WSI) are high-resolution digital scans of physical pathology slides used in digital pathology workflows.

Question 3

In genomic sequencing, 'read depth' (coverage) refers to:

Accepted Answer

How many times each base position is sequenced on average

Answer

Read depth measures how many independent sequencing reads cover each base, with higher depth improving variant-calling accuracy.

Question 4

Which encryption approach allows a cloud server to perform computations on medical data without ever decrypting it?

Accepted Answer

Homomorphic encryption

Answer

Homomorphic encryption enables arithmetic operations on ciphertext, producing encrypted results that match those of operations on plaintext.

Question 5

A radiologist's deep learning model achieves 98% accuracy on its training set but only 72% on new patient scans. This is an example of:

Accepted Answer

Overfitting

Answer

Overfitting occurs when a model learns training-specific noise rather than generalizable patterns, leading to poor performance on unseen data.
