  • 00:00:06
    Hello and welcome, my name is Manuel Quintana with Pragmatic Works, and in
  • 00:00:10
    collaboration with MAQ Software, we're bringing you today's video to look at
  • 00:00:15
    their custom visual known as Forecast using Neural Network. Now, this is a
  • 00:00:20
    fantastic visual, and it starts reaching into the realms of data science and
  • 00:00:24
    predictive analytics—which is fantastic—but it is a more advanced
  • 00:00:30
    area of conversation. We are gonna see how easy it is to implement this
  • 00:00:35
    custom visual right into your Power BI reports and start creating some
  • 00:00:39
    predictive analytic visuals, which is fantastic. Now, it should be noted that as
  • 00:00:44
    part of this visual you will need to download and install some prerequisites,
  • 00:00:48
    but all of this is done easily for you when you go to the Microsoft Store and
  • 00:00:52
    you go to install this specific visual. You'll be prompted with a message
  • 00:00:56
    letting you know that you do need to have some items installed, and there is a
  • 00:00:59
    very nice conveniently located install button right there, and it will go
  • 00:01:04
    through that process. What we're doing is we're installing the necessary R
  • 00:01:07
    packages for this visual to work. Once that's set and in place, now you can go
  • 00:01:12
    ahead and start using this custom visual and looking at data over time, maybe a
  • 00:01:17
    different type of data series, and then as well as seeing the data that you have
  • 00:01:21
    and you are presenting, we can now predict and get some results back from
  • 00:01:26
    what the neural network algorithm has learned. That is what this is all
  • 00:01:30
    about: leveraging the neural network learning algorithm, which is also known
  • 00:01:35
    like as a black box algorithm or a deep learning algorithm, and it's really great
  • 00:01:40
    at looking at nonlinear data. There are quite a few visuals out in the
  • 00:01:44
    marketplace that do predictive analytics—and they're more focused around using
  • 00:01:48
    algorithms that are great at handling linear data—but where neural network
  • 00:01:52
    shines is deriving patterns where it is nonlinear, which can be rather difficult.
  • 00:01:56
    Hopefully you're excited and you're ready to enjoy. Let's head over to Power
  • 00:02:00
    BI and see how we can put this custom visual into play.
  • 00:02:04
    Here we are looking at the Forecast using Neural Network from MAQ Software.
  • 00:02:09
    The nature of our data here is just looking at, if we look at the data view,
  • 00:02:14
    just the price of gold over time—so over years. Very straightforward, and that's
  • 00:02:18
    what we've input. If we look at the field well here for our custom visual, the
  • 00:02:23
    series can either be a time or numeric series and then our value. Now do note
  • 00:02:28
    that what we're seeing in this teal-ish color—that is our observed values. The
  • 00:02:32
    yellow is was what our predicted values are. So to look through this, lets go
  • 00:02:37
    right into the format area, so we can have an understanding of where we can
  • 00:02:40
    control this. The plot setting is where we can dictate the background color, the
  • 00:02:44
    forecast color, and the observed color, which is very important. Of course, we can
  • 00:02:49
    control the x and the y axis, but the other main element here is going to be
  • 00:02:53
    the forecast settings. Now, the default is setting this to auto, but if you have a
  • 00:02:58
    good understanding and you feel confident, you can actually control the
  • 00:03:02
    parameters that drive the neural network. We'll look at this momentarily, but I did
  • 00:03:07
    want to display it. Once you have this configured—and it should be noted—it
  • 00:03:10
    does take some time. Once you define the fields that are going to populate your
  • 00:03:14
    visual, the algorithm—the neural network—needs to run. It's going to be doing
  • 00:03:19
    analysis and creating predictions of your data. Don't worry if it's taking
  • 00:03:23
    a moment; that is the nature of this type of a visual. We can see that we do have
  • 00:03:27
    some really neat capabilities with inside of it where we can actually draw
  • 00:03:30
    boxes and zoom in to certain elements. By double clicking anywhere in the box, you
  • 00:03:34
    go back to your main view. You can enable some spike lines, so as you're moving
  • 00:03:38
    across, you can see how that correlates to the rest of the data—how we can see
  • 00:03:41
    this is a rise and there's no other peak that equals this one as far as looking
  • 00:03:45
    back in time. Of course, you may notice when we zoom in, in this area just
  • 00:03:50
    here that we have this little shaded area. This relates to the confidence
  • 00:03:55
    intervals. By default, this is turned off, but by turning this on, you now get a
  • 00:03:59
    range. You can choose—or you can see we have some confidence levels we can
  • 00:04:03
    choose with—lowering this number: having less confidence is gonna narrow this
  • 00:04:08
    range. The higher the number we're giving ourselves a little more breathing
  • 00:04:12
    room saying hey we're confident that the values in this time frame will fall
  • 00:04:16
    between these little brackets, and as you hover over,
  • 00:04:18
    you can see the information. The confidence level here for 2016 is gonna
  • 00:04:22
    be that 1373 and some change, while the yellow line is just the raw
  • 00:04:29
    predicted line. Really neat, really powerful, but as I mentioned, we could go
  • 00:04:33
    even further. If we look at the same visual but in the context of going over
  • 00:04:38
    to the format area and choosing to switch the forecast settings from auto
  • 00:04:42
    to user-defined, we have a couple of choices here. Now, of course, there's a lot
  • 00:04:47
    that goes into data science and learning, but we have some items here where
  • 00:04:51
    decay kind of controls the learning rate of the neural network. The maximum
  • 00:04:55
    number of iterations is how many times it's gonna run these numbers through the
  • 00:04:58
    neural network and coming up with different values and then coming back
  • 00:05:01
    with the best distribution. The number of units, in this case, is gonna represent
  • 00:05:06
    our series, which were going in years, so this is going to predict out to ten
  • 00:05:10
    years from where we ended our observed. Of course, epochs is going to be the kind
  • 00:05:15
    of rotations, so we're gonna have two hundred iterations over a single epoch.
  • 00:05:19
    Here, we're gonna have eight epochs. Lowering these values, of course, has less
  • 00:05:24
    iterations—there's less loading time—but there is this concept of overfitting,
  • 00:05:29
    which can occur if you start increasing these numbers. Basically, you're making it
  • 00:05:33
    learn the specifics of this data, so when new data is introduced, it may not
  • 00:05:38
    interpret that as correctly. Like I said, we're working in the realm of data
  • 00:05:41
    science, so there's a lot of information to understand here, but hopefully you can
  • 00:05:45
    see very quickly and how easily you can now already start using data science or
  • 00:05:51
    predictive model visuals here right within Power BI with the usage of this
  • 00:05:57
    Forecast using Neural Networks by MAQ Software. Hopefully you enjoyed, and thanks
