COVID 19 accelerated all transformation processes at the corporate level and today every company that wants to succeed must transform and improve its digital environment and core.

Marco Iansiti and JKarim Lakhani, professors at Harvard Business School, discuss how the pandemic has generated great opportunities for the birth or evaluation of this new type of companies.

Marco Iansiti: Okay, who is going to initiate this?

Karim R. Lakhani: You get it going.

Marco Iansiti: The AI era, it’s really defined by the emergence of a different kind of enterprise. Which is a big deal, because that doesn’t happen in business very often. Traditionally, we’ve built companies around individual units in silos. You have one silo around marketing, another around product development, and another around manufacturing.

Silos are necessary to optimize people’s work. But as the enterprise begins to incorporate digital technology, gradually, that enterprise will need to be built differently.

Modern organizations are really built around a data-centric architecture, which integrates data different parts of the way they can. Then efficiently implement technology based on that data to drive as many different processes as possible.

Karim R. Lakhani: Can I add something here?

Marco Iansiti: Yes, yes.

Karim R. Lakhani: : What I can say is the era of AI, it’s not something far away that will happen in the future. It is happening now. It is happening to us today.

Even right now, if you are looking at us on a website, you are looking at us on your cell phone. This has been enabled by companies that are directly innovating in the AI era.

The challenge for the rest of us is how do we adapt? How do we change? So that we can also be competitive with both the giants and the start-ups that are trying to make a difference.

We thought we had time. We thought many industries had time to make the adjustment. Of course it’s now, that’s no longer an option.

Marco Iansiti: Then the COVID pandemic pretty much changed everything. Suddenly, all companies had to deal with this.

Overnight, by survival, all these restaurants went digital. They started working with Uber and every possible delivery driver to make the delivery of their products happen. The whole restaurant experience, overnight, went digital.

Marco Iansiti: You know what, Karim? QR codes are everywhere in the United States.

Karim R. Lakhani: Exactly.

Marco Iansiti: Because nobody wants to go to restaurants. If you want to go and find out what the menu is, you grab the QR code on the door and you get to the website.

Karim R. Lakhani: I was so amazed at the speed. I think it was survival. It’s a survival instinct. This, for us, is the big accelerator.

Marco Iansiti: Look, it’s very simple. If you walk down the street and you see your local Chinese restaurant just using QR codes to point to their menu, a multi-billion dollar company should be able to do that too.

People Transformed. Literally overnight.

So they integrated their data and went through this big data lake.

Essentially, this infrastructure that would allow them to very quickly create predictive models around how many ventilators they might need, how many NA5 masks they need or might need. All of that had to be predicted.

Karim R. Lakhani: This requires a degree of centralization around the data.

You can’t have the cardiology unit with data outside of the nephrology unit and away from the emergency department.

You don’t just want all the data, you want to be able to see all of this and then make predictions about where capacity is needed. Where are patients expected to go through?

And providing this enterprise-wide view across the enterprise, like data integration, analytics and software, are already at the core is the big change.

Marco Iansiti: It’s almost as if the pandemic was an accelerator really, of things that people had wanted to do before and required the deployment of certain systems that, on the fly, were redesigning how the organization actually worked.

Karim R. Lakhani: Another really cool example that we’ve presented in the book, is a company called Moderna.

The big aha! for CEO Stéphane Bancel, around artificial intelligence and digitization, had come into one of their scientist’s offices.

Basically, the scientist was doing a complicated series of calculations, moving genes around. He had five screens around him and he was basically copying and pasting things from Excel in one cell to the other cell.

That he saw as a nightmare, because in the biotech world, it’s a copy-and-paste mistake, and that can mean going back six or nine months, if something by accident got overlapped or because of some careless mistakes.

They all had to be digitized and put together.

This transformation really helps with the COVID pandemic as well, because they were able, in 42 days, once they sequenced the virus, to then be able to submit to the FDA, a vaccine application.

They’re still a startup with 1200 employees, right? Competing with trying to create a vaccine with large organizations in the pharmaceutical world.

If you think about the scale of what they have they’ve been able to achieve the differences in the processes that you can implement change if you have digital data and analytics at the core of your operation.

Machine Learning is the ability of machines to learn from data without being programmed. This is used on a daily basis in platforms such as Netflix, Spotify or voice assistants like Siri.

Through the following case of how to differentiate wine from beer, Google Cloud Platform presents us: The 7 steps of Machine Learning.

From detecting skin cancer, to sorting cucumbers, to detecting when escalators need to be repaired.

Machine Learning has given computer systems entirely new abilities, but how does it really work in depth?

Let’s look at a basic example and use it as an excuse to talk about the process of getting answers, through your data using machine learning.

Welcome to the adventures of AI in the cloud! My name is Yu Feng Guo and in this program we will explore the art, science and tools of machine learning.

Suppose we have been asked to create a system that answers the question of whether a certain drink is wine or beer. We call this question-answering system a model and it is created through a process called machine learning training.

The goal of machine learning is to create an accurate model that answers our questions correctly most of the time. To train a model, we need to collect data that allows it to train. This is where we start.

¿Wine or beer?

Our data will be collected from wine and beer glasses. There are many aspects of the beverages that we could collect, from the amount of foam to the shape of the glasses. For our purposes, we will just pick a couple of simple pieces of data, the color, as a wavelength of light and the alcohol content, as a percentage.

What we are looking for is to be able to divide these two types of beverages into two factors. From now on we will call these our characteristics: color and alcohol.

The first step in our process will be to go to the local store to buy many different beverages and get the equipment to measure them. A spectrometer, to measure color, and a densimeter, to measure alcohol. It looks like our store also has an electronics section.

Once we have the equipment and the alcohol all in place, it’s time for our first real machine learning step: collecting that data. This is very important, because the quality and quantity of the data collected, will directly determine how good the predictive model can be and the data we collect will be the color and alcohol content of each drink.

This will be our training data, so a few hours of measurements later maybe we will have a few drinks and now is the time.

Now it’s time to collect the training data:

We load our data into a suitable place and prepare it for use by our machine learning training.

First we gather all the data, in random order. We don’t want the order of the data to affect what we learn, as it won’t be determinative of whether a drink is wine or beer.

This is also a good time to visualize the data, to help see if there are relevant relationships between the variables that can be engaged, as well as to show if there is inconsistency in the data.

For example, if we collect many more data points on beer than on wine, the model we train will be strongly predisposed to guess that virtually everything it sees is beer, since it would be right most of the time. However, in the real world, the model may see beer and wine in an equal amount, which would mean that it would be guessing wrong about beer half the time which we also need.

Also, we need to split the data into two parts, the first part used in training our model will be the bulk of our data. The second will be used to evaluate our model.

Maybe we would like to use the questions from the math one in the math exam, sometimes the data we collect need other ways to fit, manipulate things normalization error, duplication, error correction and others.

Workflow: Choosing a model

The next step in our workflow is to choose a model. There are many models that researchers and data scientists have created over the years, some are well suited for image data, some for sequences like text or music, some for numeric data and some for text based data. In our case we are looking at two features, color and alcohol percentage, we can use the small linear model simply and it should do its job.

Training

In this step we will use our data to predict whether a drink is wine or beer, this is similar to someone learning to drive. At first you will not know how the pedals and knobs work. However, after a lot of practice that person has become adept at driving and reacting to real world data.

We will do this to scale our particular drinks, the formula for a straight line is y equals MX plus B: where X is the input; M is the slope of the line; B is the intersection with the y-axis; and Y is the value of the line at that X position. The values we have available for us to adjust or train are only N and P: where M is that slope; and B is the intersection with the y-axis. There is no other way for the ascites to affect the position of the line, since the only other variables are X our input and Y, our output.

Review the learning formula here.

How do we continue?

The power of machine learning, in this example, was to differentiate between wine and beer, instead of using human thinking and manual rules. Also, we can use the ideas presented today in other problems, where the same principles apply in the following steps:

Collect data.

Prepare the data.

Choose the model.

Train.

Evaluate.

Adjust parameters.

Predict.

If we individualize learning, do we learn better? https://redesign.closelly.com/en/adaptive-and-personalized-learning/ https://redesign.closelly.com/en/adaptive-and-personalized-learning/#respond Mon, 21 Dec 2020 18:30:50 +0000 https://redesign.closelly.com/?p=13401 Adaptive and personalized learning enables better understanding and longer retention, leading to increased success rates...

MOOCs (Massive Online Open Courses) are Massive Open Online Courses (MOOCs), whose learning modality is online and aimed at an unlimited number of students who can have access to traditional course materials, such as reading information, videos and quizzes, which can be reinforced by online tutors. MOCCs have revolutionized distance education, but have they revolutionized learning? Learning must be adaptive and personalized. Otherwise, the results may not be positive.

In this TedEx Barcelona talk, Ivan Ostrowicz, co-founder of Domoscio, a company specializing in adaptive and personalized learning. According to Ostrowicz, all people learn differently so having an individualized and personalized education is ideal.

Iván Ostrowicz holds an engineering degree from the Polytechnic University of Catalonia and ENSIMAG, and an MBA from Neoma Business School. He has international experience in the field of information systems and organizational management, acquired in large companies such as Air France and EY. He is co-founder of Domoscio, a company specialized in adaptive and personalized learning.

According to Iván Ostrowicz

Since we’re going to talk about education, training and this sort of thing, let’s start with a little bit of participation. I’m going to ask you to raise your hand if you think we all learn in the same way.

Raise a hand and I’ve always finished the exercise and I’ve got about 23 people. I have done it all over Europe and always the same result.

It is a fact that we all learn differently and the reality is that we have an education system, where we have one teacher for 30 students. In the university system, it’s one teacher for 200. If we think about lifelong learning, or many of the modern learning systems, we have one teacher with one pedagogy. With one methodology for 10,000 20,000 or 100,000 participants.

But let’s go a little bit further and let’s see if you remember anything about when we learned in school. Let us complete this sentence together: I learn, you learn, he or she learns, we all learn.

At the end of the 19th century, Hermann Ebbinghaus, considered the father of experimental psychology in education, conducted an experiment in which he demonstrated that, after a month, if we do not study and do not review, we forget 80% of what we have learned.

So, we are faced with two facts: we all learn differently and we all forget what we learn. Therefore, it implies the challenges of how we personalize learning and how we make what we have learned, consolidate it and remember what we have learned.

Part of the answer can be found in cognitive science.

In 2010, Ming Zher Poh from Harvard and MIT, did an experiment of a device that connects a person and allowed to see the brain activity doing different activities. As you can see the brain activity in class was the same as when we watch TV. Sorry for the teachers that you are in the class is only with one particular teacher.

In the same sense, if we see for example, when we were in the lab and we are experimenting there is much more activity and when we are doing exercises there is also much more activity.

In fact, in 2006 Rodriguez, conducted an experiment to find out what was a good study method and separated groups to which they had to learn from a text:

The first group, he allowed to read the text four times.

The second group read the text once and had them do a battery of exercises three times.

After a month, he found that the people who had done two exercises remembered 52% more of what they had learned and, above all, had spent four times less time studying.

I could go on and on about Leitner’s system. It is a system of cards where you have a question on one side and answers on the other, which you put further away in a drawer as you learn about learning speeds, learning preferences and different intelligences.

And so we can follow another part perhaps of the answer and we can find it in new technologies.

If today we talk about new technologies in education it is big data. What is big data? It’s that impossible because we generate data all the time. When we use the phone, when we use the platform, when we are on the internet and all this, today it is very easy to store it. It’s cheap and we can easily access this information.

Think about when you put something in Dropbox, that both of them are copied by different systems, but on the other hand with big data it is possible as well. We have a computational capacity of a power that didn’t exist before, which in fact is also cheap and easy to access. So all the artificial intelligence algorithms developed between the 80s and 90s of the last century are completely relevant again and allow us to do things that we couldn’t do before. So if we combine the two the cognitive sciences with big data and artificial intelligence.

Adaptive and personalized learning

In fact, IBM in 2013 considered the combination of these three fields to be the five technologies that were to emerge and revolutionize the field of education. It’s only been three and it’s called adaptive and personalized learning. This consists of analyzing everything that students do on a platform: the exercise results; which path they have followed; have they consulted help; if they have better results when they watch a video, then do an exercise and then on a text. All this combined with the different elements that allow, experimentally, to propose a learning experience adapted to each person. Adapted to their level, their pace and their preferences.

We have already done this and have been working with a French publisher with content for 10 year olds in mathematics, French and English. The publisher provides the content adapted to work with these algorithms and we put it on a platform: on an app, on Ipads connected to our algorithms.

We see on this platform and we analyze everything the students do, which allowed that, with 400 students, 87% of our recommendations through this means were successful and allowed the student to reach the end of the process. That is, they learned something. On the other hand, when they were blocked because the content did not exist on the platform, it was very good, the content was more difficult, or for another reason, the teachers had learning analytics that allowed them to know each student, where he was and this already makes a human intervention.

On the other hand, as you can see in number two, what we did after they had learned something, is a question to see if they really understood the concept. From that question, what we did was to calculate when they were going to forget that concept, we made it easier for them to study. In other words, we made it easier for them to nail less CO2 and we sent them a question about the same concept and to refresh them this question was always changing. Because we didn’t want them to remember the question and not the concept behind it.

Another project is a customer project in a completely different situation. That is in the training of managers to be good bosses. In this case, the training is given in person with a teacher in which there were different role-plays. As in different situations, the boss had to behave and after the training day, we sent them a battery of questions with one question for each concept. With this, we knew what they had understood and what they had not understood.

From this point on, again we make them a review schedule, where we send them a question about the good concept so that they will not forget it. Just before what we forgot, we presented it. This obviously also shows that the time in which we forget something is not the same for each person. Nor for every concept. Maybe because we love mathematics and it is much less difficult for us to remember, but if we don’t like history we will have to work harder.

Results of Adaptive and Personalized Learning

The outcome was that, on average, people who underwent this training remembered 79% of what they had learned after three months. That’s 8 concepts out of 10. The person who used the system more reached up to 90%, while the one who used it less only remembered 5%.

Now, let’s address the issue of the many. Currently, there is a dropout rate between 75% and 95% for those who complete a MOOC. Only 5% to 25% successfully finish.

On the other hand, MOOC platforms have a large number of participants generating a wealth of data. We are currently working to incorporate our technology into these modes. We won’t just consider the path each person has taken or their exercise performance, such as how they respond, whether they prefer videos, or achieve better results by reading text.

What we will do is evaluate user responses in the forum. In other words, if a participant didn’t understand a concept and asked a question, and if the response is considered good by others, their score will be elevated.

We will take into account that score, recognizing that the person already knows and understands certain concepts well. Therefore, we don’t need to make them go through that chapter again, perhaps allowing them to progress faster or proposing a more challenging level. We aim to maintain engagement with a bit of participation. I wish I had this kind of solution when I was a student.

Today, many things are changing in education. The many, for instance, have improved access to training, but it hasn’t necessarily improved education itself. Considering that today we have to learn throughout our lives, this type of solution becomes even more crucial.

Big data for learning exists, and it’s called adaptive and personalized learning. It is disrupting pedagogical models globally, projecting a perspective of lifelong personal development. In essence, adaptive and personalized learning allows for better learning and longer retention.

Thank you very much!
