@SaraBonnar what a shame. I have done some futureLearn courses, of course there have been some mistakes and lots of doubts from students, but this it's the first one where the lecturer doesn't actively check the course lessons. Maybe they shouldn't have launch the course until the lecturer were able to pay the proper attention.
-
@SaraBonnar To rate the course you have to mark more than 90% of steps as completed, then futurelearn email you to rate the course, usually takes a day or two after finishing to receive the email
-
If you haven't tried to contact with future learn, try with the support button in the bottom right of these page.
-
Could you get any help from futurelearn staff?
-
@AddyFletcher Yes I thought I was wrong, but there is definitely something wrong with the quiz and tests. I already gave a low rating to this course, because yes everyone make mistakes, but the lecturer of the course haven't say anything about this comments and those who pay for the upgrade are getting low grade due to the mistakes in the tests.
-
@SaraBonnar I don't know about the test, I haven't upgraded the course. If your have found incorrect answers also in the test I suggest to you to don't take any more test and ask to the lecturer about these issues. I don't know if these can be somehow reported to futureLearn

Hey, I only get correct answers at questions 2 and 5:
Question 1: I get 405.71 and correct answer is 401.55
Question 3: I get 14.04% and correct answer is 13.90%
Question 4: I get 2664.75 and correct answer is 2301.91

I get incorrect answers at question 3 ( I get 186.92 and correct answer was 185.05) and question 5 (I get 176,231.62 and correct answer was 174,469.30). I solve the excercises using excel: =FV(0.08,14,0,60000) (for question 3) and =PV(0.07,1,0,200) (for question 5). Can someone explain me where I made a mistake.

Thanks. I started to use R because I am an accountant and I am looking to use AI techniques to improve my career path. I will need programming skills but I am not looking for a programer job and for that R is the best programming language ( https://towardsdatascience.com/the-8-most-popular-coding-languages-of-2021-b3dccb004635 ).

Some articles talk about AI like it was here and it was already capable of everything and in others its say that AI career will froze again and fall into the deep. Is true that AI intelligence have had rough times, called winters, three to be exact, but I don't think that will happen again. However I don't support either that AI is at its peak. AI won't stop...

In my little programing experience I haven't face a problem that can't be solve with this kind of logic. Logical variables and if-else statements are a power tool

Being a professional programmee sounds good. I will like to write code for business management, I have some experience in the area but I am looking to improve my programing skills

David Diaz made a comment
I do think that the comparison between the tea-making algorithms and programing is a fair one. These could be useful because it could be a good example to also teach how functions in code work. If sugar or not, if milk or no, elaborate this statements with this examplea will make easier to explain how functions works.

It will depend on the subject of the assignment. I personally think that when someone is studying should look at both subject-specific and learner dictionaries.

Another feature for a successful student that I didn't mentioned in the step 1.3 and that is said and explained in the video would be to become part of the learning process of the learners group, actively participating in group study so will be able to learn no just from the tutor if also from is peers

I think there is not one thing or a conjunction of features that we can use to define a successful student.

They faces a lot of risks, for example. Any change in the relationship between two countries could result in an increase in import-export taxes. This will damage it with a increase of costs. Regarding to legal aspects Amazon has already faced problems in countries like Spain for mistreatment of its workers.

Economics and Political features impact in my country, Cuba, are both driving by the economic embargo of USA and the protectionist contra measures that the government has taken.

The biggest pro is autonomy. As said in the video "I think that’s the best part of having your own business and, you know, it’s yours to do what you like with it". And biggest con it is the lack of security of the first stages of creating a Business.

Good examples of Polycentric global companies are fast food business as explained in the video, MacDonald's or Pizza Hut.

I think that my business idea relates best with the Ubiquitous category. And regarding to how logos reflect vision statements I think it is not that simple.

I think that a logo that can show the...

As I mention in the comments of the previous lesson an appropriate strategy tool will come from the conjunction of the PESTLE and SWOT analysis. I think that my Business Idea is viable.

Do we need to choose at all? That could be another question. I think PESTLE analysis can be use as base, seen and how these factor will affect our SWOTs. I believe this is the way of achievement a deepest analysis.

Those articles are very good. After studying the lessons and the articles share by Derek Allen I found several similarities between human and machine learning styles.

My answer has change. There are more differences between Natural and Artificial intelligence than just biological or non. The human intelligence capacities of empathy, morality, creative, be awer of its environment, for just mentiont some, are not yet able for AI.

Everything was surprising. This week was full of new concepts and topics to me.

I agree with Mark Elshaw, the greatest challenge is to accomplish that an AI has empathy, morality and awernes of it is impac in the environment. But I don't see an issue of discussion. Should AI have it or act like it? To me the answer is that AI should definitely have these "abstract" capabilities. Because as stated in previous lessons these capacities are...

A lot of concepts regarding intelligence that it did not know before.

I consider this very useful. This understanding of how works the human brain is what leeds to ML algorithms. Input-process-output compare output with true value and learn from errors.
And these studys of the human brain inspired the creation of Artificial Neural Networks.

David Diaz made a comment
Artificial intelligence it is a concept that has evolve with the time. A good example of it are the first algorithms used to play chess that were considered AI. But nowadays as stated in the video to define an AI algorithm this must be releted to a ML technique that allows it to learn from experience.

David Diaz made a comment
As stated in the lesson, what is called intelligence, is affected by culture. Therefore as I said in the comments in the lesson "The need for greater diversity in AI algorithms" to build AI algorithms should be use data truly representative of everyone or at least representative of the environment in which will be use.

The need for women in AI is necessary as it is diversify in every area of study. Having a balance diversity: women and man, from developed and poor countries, and... will always affect positive in the learning rate of the students.

I believe it is somewhere between the both ways explained in the text. When a test it is done, either to measure intelligence or the knowledge of a student in a subject, environmental factor are pretty much left aside. What about if the person taken the rest dose not feel well with having to do a test or if the student doesn't like the subject. Therefore I...

I agree, greater diversity in AI algorithms can be one way to address unconscious bias in AI. To my understanding this mean not only including everyone in the development of the AI but rather than using data that it is truly representative.

These cobsiderations can be easily related to the data and anlyses required for the milk supply chains when we look at distribution companies.
