Consider the following scenario: You are browsing the web for a very specific and important piece of information. However, you are not quite sure how to find it and adopt an iterative process of refining your query after every search, depending on the shown results and a skim of the first few websites. Is it better to use a connection-oriented or connectionless service for your communication in this scenario? Explain your answer in 1-4 sentences.	Because we are browsing for a very specific and important piece of information it is better to go with connection-oriented service because it "guarantees" that all data packets are received in the same order as those sent by the sender which isn't necessarily the case with connection less service and therefore wouldn't be reliable	Connectionless, because you will communicate with various partners (websites) for short periods of time. If you would initiate a connection with every website you skim, that would incur a lot of overhead in the connecting and disconnecting phase, just to have very short data transfers.	0.5	SAF	0.5	0.000227	391

When you build a series circuit using 2 bulbs and one D-cell, the bulbs are very dim. When you build a parallel circuit with 2 bulbs and one D-cell, the bulbs are bright. Why are the bulbs dim in series and bright in parallel?	They are dim in series because it takes up more electricity than the parallel.	In series, the 2 bulbs have to share one pathway, so the light is dim. In parallel each bulb has a direct path to the D-cell energy source so both bulbs shine brightly.	0	SciEntsBank	0	0.000092	437

null	Back propogation usually occurs in a multi layer perceptron. It uses a non linear activation function. Basic elements: 1. Functional signals: These are the input signals, which passes through the network from left to right. As the name denotes it performs a usefull function at the output of the neuron and another reason for the name is that the functional signals are calculated based on the parameters and the activation function. 2. Error signals: Error signals propogate usually in the reverse direction which contains the error based on the desired output. It consists of 2 phases: 1. Forward phase: In the forward phase the signals propogate from left to right. Weights are fixed and passes through all the layers of the network, that is undergo all the activation. 2. Reverse phase: In the reverse phase, the local gradients are calcualted and are propogated through in the backward direction. Here weights change.	Backpropagation lowers the error of a MLP level by level recursively backwards. It back propagates an error from the last layer to the first layer by updating the weights. The updates are determined by the local gradient at each level which is computed by partial derivatives of the error and chain rule.	1	DigiKlausur	0.5	0.001522	357

Consider the following scenario: You are browsing the web for a very specific and important piece of information. However, you are not quite sure how to find it and adopt an iterative process of refining your query after every search, depending on the shown results and a skim of the first few websites. Is it better to use a connection-oriented or connectionless service for your communication in this scenario? Explain your answer in 1-4 sentences.	A connection-orientated service would be better because it saves some bandwidth in this specific case (multiple messages being transmitted between the same two parties). With only a single message transmitted, the overhead would be too large. But in this case it seems to be the better approach since only one connection establishment with the search engine is needed.	Connectionless, because you will communicate with various partners (websites) for short periods of time. If you would initiate a connection with every website you skim, that would incur a lot of overhead in the connecting and disconnecting phase, just to have very short data transfers.	1	SAF	1	0.00008	411

Software-defined Networking (SDN) introduces separate control and data planes to manage network flows. Please explain the responsibilities of each plane in 1-2 sentences. Further, name two tasks the SDN controller takes care of.	The Control plane inludes the control logic. They define the routes for the packets and therefore manage the netowork graph. The control plane is logically centralised and installs the routing tables into the data plane. The data plane exists on the level of the routers, and is in charge of forwarding the packets in the network. The SDN controller installs the flow tables into the switches and receives the requests of the network switches/routers.	Control Plane: The control plane is logically centralized, but can be physically distributed (multiple coordinating control servers for higher availability and scalability). One of the following responsibilities should be given: ● decides the route for the packet/data ○ Control servers manage the network graph, define routes, and update the flow tables of connected switches. ● handles unprocessed packets coming in from the data plane Data plane: Responsible for packet forwarding. Individual switches just execute actions according to their flow tables decided upon by the control plane. The following are the tasks taken care of by the controller: ● Configuration of forwarding tables ● Injecting packets ● Events from switch (packet-in) ● Collection/Monitoring of traffic statistics ● Discovery of topology ● Inventorying what devices are within the network and the capabilities of each device ● Interfaces with control logic (control “application”) via the northbound interface(s) ● Implements a southbound interface to interact with the data plane. ● Implements the control plane.	1	SAF	1	0.00008	237

After several days, all of the water had evaporated from one of the containers. The other container still had some water. Which container, X or Y, was empty? Explain why the water in that container evaporated more quickly than the water in the other container.	Because the container X had more surface area, and the more surface area the faster it evaporates.	Container X has more surface area or more water exposed to the air so the water evaporated faster.	3	SciEntsBank	1	0.000056	745

Consider the following scenario: You are browsing the web for a very specific and important piece of information. However, you are not quite sure how to find it and adopt an iterative process of refining your query after every search, depending on the shown results and a skim of the first few websites. Is it better to use a connection-oriented or connectionless service for your communication in this scenario? Explain your answer in 1-4 sentences.

Because we are browsing for a very specific and important piece of information it is better to go with connection-oriented service because it "guarantees" that all data packets are received in the same order as those sent by the sender which isn't necessarily the case with connection less service and therefore wouldn't be reliable

Connectionless, because you will communicate with various partners (websites) for short periods of time. If you would initiate a connection with every website you skim, that would incur a lot of overhead in the connecting and disconnecting phase, just to have very short data transfers.

When you build a series circuit using 2 bulbs and one D-cell, the bulbs are very dim. When you build a parallel circuit with 2 bulbs and one D-cell, the bulbs are bright. Why are the bulbs dim in series and bright in parallel?

They are dim in series because it takes up more electricity than the parallel.

In series, the 2 bulbs have to share one pathway, so the light is dim. In parallel each bulb has a direct path to the D-cell energy source so both bulbs shine brightly.

Back propogation usually occurs in a multi layer perceptron. It uses a non linear activation function. Basic elements: 1. Functional signals: These are the input signals, which passes through the network from left to right. As the name denotes it performs a usefull function at the output of the neuron and another reason for the name is that the functional signals are calculated based on the parameters and the activation function. 2. Error signals: Error signals propogate usually in the reverse direction which contains the error based on the desired output. It consists of 2 phases: 1. Forward phase: In the forward phase the signals propogate from left to right. Weights are fixed and passes through all the layers of the network, that is undergo all the activation. 2. Reverse phase: In the reverse phase, the local gradients are calcualted and are propogated through in the backward direction. Here weights change.

Backpropagation lowers the error of a MLP level by level recursively backwards. It back propagates an error from the last layer to the first layer by updating the weights. The updates are determined by the local gradient at each level which is computed by partial derivatives of the error and chain rule.

If the question is Knowledge-Based, I will do the following: I can assume the question as a query. Because of having a very large text: Firstly, I would segment these texts to shorter passages like paragraphs. Then, I would build semantic representations to the query such as locations, dates, times, entities, numeric forms/quantities. At last, In order to determine the semantic relation between the question and passages, I would map these semantic representations between query and passages, using WordNet like lexical databases. In that way, I can find the most relevant text.

We need to do some extractions like answering. I mean, let's assume our question is "Who is Ada Lovelace?" or "Atatürk, is alive or not?". Firstly, we need to do classification our answers. Then we need to do to obtain keywords, normalizing, tokenizing etc which will from Query Frame. We can say if our question begins with Who-Whom , we can assume answer will be PERSON, And if it begin with Where, it should be LOCATION. Now, let's go back to our question. Answer type will be person and "ada lovelace" our token. or another question. Answer type: Yes/No . tokens= "atatürk" "alive" We can searching in our corpus, for our tokens. And we can take answers which is related to our question then we measure semantic similarity(word/text/sense level)

Please explain the problem with "Distributed Queue Dual Buses" that was discussed in the lecture in 1-3 sentences.

How much data can be reserved in a node depends on the location of the node. It means the one which is close to the frame generator can get more data than which in the middle. Obviously it's unfair for each node.

Depending on your position in the bus station have a disadvantage/advantage when reserving transmission rights.

She put her feet heel-to-toe and counted the number of shoe lengths it took to measure the rug. She found the rug was 18 shoes long and 12 shoes wide. Sharice did the same thing in her room to measure the space for the rug. Her floor was 18 shoes long and 12 shoes wide. A perfect fit! Sharice bought the rug and took it home. To her dismay, she found it was too short and too narrow for her bedroom! What could Mary and Sharice do to better measure the size of the rug?

Anna spilled half of her cup of water on the kitchen floor. The other half was still in the cup. When she came back hours later, all of the water on the floor had evaporated but most of the water in the cup was still there. (Anna knew that no one had wiped up the water on the floor.) Explain to Anna why the water on the floor had all evaporated but most of the water in the cup had not.

The water on the floor evaporated quicker because of the surface area was big. But the water in the cup evaporated slower because the surface area was small.

The water on the floor had a much larger surface area. The water in the cup had a much smaller surface area.

Software-defined Networking (SDN) introduces separate control and data planes to manage network flows. Please explain the responsibilities of each plane in 1-2 sentences. Further, name two tasks the SDN controller takes care of.

The Control plane inludes the control logic. They define the routes for the packets and therefore manage the netowork graph. The control plane is logically centralised and installs the routing tables into the data plane. The data plane exists on the level of the routers, and is in charge of forwarding the packets in the network. The SDN controller installs the flow tables into the switches and receives the requests of the network switches/routers.

Control Plane: The control plane is logically centralized, but can be physically distributed (multiple coordinating control servers for higher availability and scalability). One of the following responsibilities should be given: ● decides the route for the packet/data ○ Control servers manage the network graph, define routes, and update the flow tables of connected switches. ● handles unprocessed packets coming in from the data plane Data plane: Responsible for packet forwarding. Individual switches just execute actions according to their flow tables decided upon by the control plane. The following are the tasks taken care of by the controller: ● Configuration of forwarding tables ● Injecting packets ● Events from switch (packet-in) ● Collection/Monitoring of traffic statistics ● Discovery of topology ● Inventorying what devices are within the network and the capabilities of each device ● Interfaces with control logic (control “application”) via the northbound interface(s) ● Implements a southbound interface to interact with the data plane. ● Implements the control plane.

Advantage: better efficiency Disadvantage: needs frame waiting for transmission

Frame bursting reduces the overhead for transmitting small frames by concatenating a sequence of multiple frames in one single transmission, without ever releasing control of the channel. Advantage :it is more efficient than carrier extension as single frames not filled up with garbage. Disadvantage :need frames waiting for transmission or buffering and delay of frames

Bias-variance dilemma is a principle supervised learning problem. The dilemma arises due to the variance of data and bias of model. When there is high bias, the model fits the training data perfectly but suffers from high variance, when the bias is low the variance reduces but the model doesn’t fit the data well. This dilemma makes the generalizability difficult to achieve.

After several days, all of the water had evaporated from one of the containers. The other container still had some water. Which container, X or Y, was empty? Explain why the water in that container evaporated more quickly than the water in the other container.

Because the container X had more surface area, and the more surface area the faster it evaporates.

Container X has more surface area or more water exposed to the air so the water evaporated faster.
