4.The results of a hypothetical study to measure test performance of the PCR (polymerase chain reaction) test for Covid-19 are shown in the following table.

Calculate the (A) accuracy, (B) precision (positive predictive rate, PPV), (C) recall (sensitivity, true positive rate, TPR), (D) true negative rate (TNR) and (E) F1-measure. Note: Show the result by rounding up the 3rd digit after the decimal point, e.g. 0.9876 should be 0.988.
3. Hamming code is a technique used to detect and correct errors in data transmission. It achieves this by adding specific check bits to the data bits. It enhances the reliability and stability of systems. After encoding with Hamming code, the value is 1101110101. Which bit is INCORRECT, and what is the CORRECT value?
2. Assume that there is a four-frame physical memory in the system. Initially, all frames are empty. Given the reference string: ACDFCBCADAFBAC, how many page faults generated by the LRU page replacement scheme? Show your work.
30. In the Internet of Things (IoT), what is the MQTT protocol? (A) MQTT is a protocol for communication between IoT devices, with its main feature being the ability to provide real-time communication. (B) MQTT is a protocol for communication between IoT devices, with its main feature being to provide efficient low-power communication. (C) MQTT is a protocol for communication between IoT devices, with its main feature being to provide highly secure communication. (D) MQTT is a protocol for communication between IoT devices, with its main feature being the ability to provide wide-area network communication. (E) MQTT is a protocol for communication between IoT devices, with its main feature being to provide highly scalable communication.
29. In the context of generative AI, which technique involves training a model to predict the next token in a sequence based on the previous tokens? (A) Reinforcement learning (B) Markov chain Monte Carlo sampling (C) Variational autoencoder (D) Long short-term memory networks (E) Generative adversarial networks
28. What is LoRaWAN? (A) LoRaWAN is a wireless radio frequency communication technology, characterized by providing low-power long-distance communication suitable for IoT devices. (B) LoRaWAN is a cellular network technology, with no significant difference from traditional cellular networks. (C) LoRaWAN is a solar-powered IoT technology, characterized by providing efficient lowpower communication. (D) LoRaWAN is a wireless local area network technology, offering longer communication distances compared to traditional Wi-Fi. (E) LoRaWAN is a wireless bridging technology for IoT, primarily used to connect different IoT devices.
