@JohnS. There were a multitude of local political forces, by that time majority Muslim, while some welcomed the Turks, some of them they found it more convenient to throw in their lot with the Spanish. Political expedience overrides all religious considerations.

@VladimirSoyref Mr. Soyref, I did look, and with respect, please look again. There are two "Qara Qoyunlu 15th Century", one marked with a white star and the other a black star. There would be no need to show the same political entity twice in a map, unless different time periods were involved, if it were 1) Qara Qoyunlu 14th Century, 2) Qara Qoyunlu 15th...
-
@ChristineMcDowell Thank you. As the link shows Aq qoyunlu and Qara qoyunlu were separate and quarreling tribal confederacies, and I can only conclude that the white star was meant for the white sheep and black star for black sheep.

The memoirs of Khaireddin Barbarossa (Gazavat-ı Hayreddin Paşa=Wars of Khaireddin Pasha), I believe there's no English translation (way overdue I think), but it was widely translated from Ottoman Turkish to present day Turkish for some time now. In fact a Spanish translation was printed as early as 1578: "La vida y Historia de Hayreddin Ilamado Barbaroxa,...

I believe the biggest factor is the need of the many unfortunates in Europe (commoner, serf, smallest child of noble family, marginalized religious community member) to fend better (or rather survive). In fact I find that aspect very similar to the biggest factor behind the Crusades.

I'm a little confused. Could the white star on the map mean Aq Qoyunlu (White Sheep)?

İbrahim Atakan Kubilay made a comment
Reconquista was a Crusade (or branded as such as a PR campaign), and the same attacks on the Jews that preceeded the first Crusade in XI.th century were still popular.
At this point it may be worth noting that Khaireddin Barbarossa, acting as a semi-independent proxy of the Ottoman Empire, was running a huge transport operation carrying Muslims from Spain...

Sorry, I'm confused. "1492–1494, so a decade after Columbus’ first voyage". Columbus' first voyage was in 1492, so how can this be a decade later?

In the programming exercise in Week 1 we learned that TCP, unlike UDP, acts as a continuous message stream between the client and the server. Here we learn TCP works in packets as well. So my question is: Does TCP work in packets like UDP(different in other ergards), BUT socket abstraction allows us to see TCP connection as a continuous transmission?

The greatest requirement of a leader in a crisis scenario is I think the ability to improvise under unforeseen circumstances. A good team is one that can put in the effort for a common purpose with no doubt in their mind that the leader and other members all undertake their own respective responsibilities.

I think NIMS, when clearly defined, greatly simplifies and streamlines the command structure and prevents time consuming bickerings over the question of authority.

Well, understanding that he abided by the law in his actions, albeit against his own moral judgement and common sense, I don't think he should be subject to criminal investigation. If anything, the author of the law is responsible(although not necessarily criminally) for not having foreseen the consequences of his/her law.

This is a really convoluted problem as medical doctors, for example, have become hesitant to intervene in emergency situations, as there were incidents where the victim later filed a lawsuit for malpractice against the doctor.

1) We could use a specila character like \, to tell the parser that this is a comma string rather than a tuple separator.
2) I can have a non-common format that I have created for a specific purpose, and pickle would have no idea how to interpret and serialize that, and making sure that it comes(it's parsed) correctly at the other end. -
Theoretically there's no limit to the type of data you can transmit and receive over a wifi network because data are essentially bit streams, HOWEVER in practice, because of bandwidth limitations, you will have a difficult time streaming video and even audio. Moreover, wifi is notoriously bad for passing sensitive information such as bank account numbers and...

I have a few online videos, but the view/like count never goes above the number of close family and friends to whom I had sent the links. It's rather hard for a video to make it to big view numbers. And video shooting and editing takes a lot of time. I'm yet to find a good free video editing tool that can handle 4K without stalling.

There is also the case of negative overt reactions when something bad happens. It helps release anger and frustration, even though may not be nice to hear.

I have chosen "perseverence" because that's what comes to my mind immediately when I think of resilience. More creatively, I have chosen "Rhino Skin", a term used for the ability of not being affected by rude comments, reprimands, insults and failure.

At around these times, King Charles V of Spain was also waging war against the semi-autonomous proxy of the Ottoman Empire on North Africa lead by Heireddin Barbarossa, and interestingly Cortes appears to have taken part in one of the Mediterranean campaigns, prompting Barbarossa to mention: "That Cortes was a very cruel infidel who had grilled thousands of...

I wrote something similar as a comment on an FL course on nuclear power in the context of a UK made nuclear powerplant, and I'll write it again in the context of ZX Spectrum. I'm amazed that the British, unlike many other nations, like to build their own product even if it may not be as good or price effective as the ready-to-buy competition. And in many...

Hi all, I'm Atakan, a computer engineering PhD and instructor from Turkey. I have mainly conducted research on optical guitars. I have been playing video games since Intel 286 times, and I enjoy listening to music very much. Attempts at bass playing have stalled for now.

With the advent of Big Data and Machine Learning, Statistics became a good career opportunity. I'm a computer engineering PhD and I see (not without envy) most contributions to these fields made by statisticians than computer scientists. I'm past the financial and age marks for salvation, but the younger aspiring students should definitely see if they like it.

Would I be right to assume there is a convolutive composition as well for modeling more complex phenomena?
-
@AlexandraRodriguez If the holes are accompanied by true values on both sides, I believe interpolation can fix it before applying any forecasting. As discussed by Prof. Chris, it's a good idea to use different methods(in this case interpolation methods) to see if they make a big difference. I find cubic splines work best for many scenarios.

Thank you for the great course. I think the content was good for a short course. However, as one other reviewer pointed out, the name "A Gentle Introduction to AI" would be more appropriate, because with the current name, I expected the course to be all about how the AI falls short in its progress and how it's used as a marketing buzzword by businesses.

When hardware was limited, all efforts were aimed at writing very efficient and fast code. After the hardware developed remarkably, it didn't make much difference and even the teaching of efficient code writing lagged behind. Now we sort of go back to the beginning, with the introduction of big data algorithms massive computing power is once again needed, so...

@RobertGillespie You are very welcome sir. I unfortunately have no idea why it may not have worked with direct editing. What I did was to google the last part of the error message "org.rosuda.REngine.REngineException: Parse error" and there I found that running the commands from a text editor worked fine.

Well, if ZeroR did better, it would be an even greater scandal for the ML community. However, let's keep in mind that the image data can be useful for detecting other things.

Dear Sir,
1) I believe it could be a typo in your script(like ; instead of : may be?).
2) Another option is to check you have made a dataset connection to the Scatter Matrix.
3) Have you configured ArffLoader to open iris.arff? -

Quiz 3.9 was one of the more enjoyable ones in the course.
From a software standpoint, it had to be coded such that "skewness(rdata)" returns skewness of all numerical attributes, while allowing you to pick specific attributes like "skewness(rdata[2,5])" where attributes indexed 2 to 5 are used. But that's the "price" for free software I guess :)

A full time job. The irony is that small businesses need social media as a cheaper alternative to traditional advertising, yet they need to hire a full time worker to do it properly which would cost just as much-if not more- as traditional advertisement. A small family business member would have little time to be that active on social media.

So the model with lagged variable is linear on 2D with the two variables as the axes, so the actual prediction value defines a plane in 3D(att1,att2,prediction). When this 3D prediction is mapped to 2D(att1,prediction) we get the non-linear, cyclic pattern. Does it sound right?

@SteveDawson Yes, I agree. I find conceptual explanations like presented here very useful, and in fact should be given before the math details. Instead, we feed the math to our students, then show them where the math is used, which understandably discourages them.
