What is Neural Networks?

This topic that we need to spend some time looking through is the idea of neural networks. You will not get very far with your work in deep learning if you are not able to work with these neural networks, and there are a few different types that you can create and work with as well. So, let’s dive right in and learn more about these great neural networks that can help us with our deep learning models.

Neural Networks

The first type of network we are going to look at is the “normal” type of neural network. These neural networks are going to fit into the category of unsupervised machine learning because they are able to work on their own and provide us with some great results in the process. Neural networks are a great option to work within machine learning because they are set up to catch onto any pattern or trend that is found in a set of data. This can be done through a variety of levels, and in a way that is going to be much faster and more effective than a human going through and doing the work manually.

When we work with a neural network, each of the layers that we will focus on are responsible for spending time in that layer, seeing if they are able to find a pattern or trend inside the image, or through the data, that it looks at. Once it has found a trend or a pattern, it is going to start its process for entering into the next layer. This process is going to continue, with the network finding a new pattern or trend, and then going on to the next level, until it reaches a place where there are no more trends or patterns to find.

This process can end up with a lot of different layers, one over the top of the others again and again until you have been able to see the whole thing that comes in the image. When the algorithm is created, and the program can make a good prediction based on what is in the image or in the data that you present, then you know that it has all been set up properly.

Before we move on though, we have to remember that there are a few parts that will start to occur at this point, based on how you set up the program to work. If the algorithm was able to read through all of the layers and the steps above, and it had success with reading through the different layers, then it is able to make a good prediction for you. If the algorithm is accurate with the prediction that it made, then the neurons that come with this algorithm will strengthen and become faster and more efficient at their job overall.

The reason that this happens is that the program is relying on artificial intelligence, and more specifically on deep learning, in order to create those strong associations between the patterns it saw and the object. Keep in mind that the more times that the algorithm is able to provide the right answer during this process, the more efficient it will become when you try to use it another time as well. The neurons get stronger, and you will see that the answers come faster and are more accurate overall.

Now, if you haven’t been able to work with machine learning and deep learning in the past, it may seem like these neural networks would be impossible to actually see happen. But a closer examination of these algorithms can help us to see better how they work and why they can be so important to this process. For the example that we are going to work with, let’s say that we have a goal to make a program that can take the image we present, and then, by going through the different layers, the program is able to recognize that the image in that picture is actually a car.

If we have created the neural network in the proper manner, then it is able to take a look at the image that we use and make a good prediction that it sees a car in the picture. The program will then be able to come up with this prediction based on any features and parts that it already knows comes with a car. This could include things like the color, the license plate, the door placement, where the headlights are, and more.

When we take a look at coding with some of the traditional methods, whether they are Python methods or not, this is something that you may be able to do, but it takes way too long and is not the best option to work with. It can take a lot of coding and really just confuse the whole process. But with these neural networks, you will be able to write out the codes to get this kind of network done in no time.

To get the neural network algorithm to work the way that you want, you have to provide the system with a good and clear image of a car. The network can then take a look at that picture and start going through some of the layers that it needs to work with to see the picture. So, the system will be able to go through the first layer, which may include something like the outside edges of the car.

When it was done with this, the network would continue on from one layer to the next, going through however many layers it takes to complete the process and provide us with a good prediction. Sometimes this is just a few layers, but the more layers this program can go through, the more likely it will provide an accurate prediction in the end.

Depending on the situation or the project that you want to work with, there is the potential for adding in many different layers. The good news with this one is that the more details and the more layers that a neural network can find, the more accurately it can predict what object is in front of it, and even what kind of car it is looking at.

As the neural network goes through this process, and it shows a result that is accurate when identifying the car model, it is actually able to learn from that lesson, similar to what we see with the human brain. The neural network is set up in a way to remember the patterns and the different characteristics that it saw in the car model, and con store that information to use at another time if it encounters another car that is the same again. So, if you present, at a later time, another image with that same car model in it, then the neural network can make a prediction on that image fairly quickly.

There are several options that you can choose to use this kind of system for, but remember that each time you make a neural network, it is only able to handle one task at a time. you can make a neural network that handles facial recognition for example, and one that can find pictures that we need in a search engine, but you can’t make one neural network do all of the tasks that you want. You may have to split it up and make a few networks to see this happen.

For example, there is often a lot of use for neural networks when it comes to creating software that can recognize faces. All of the information that you need to create this kind of network would not be available ahead of time, so the neural network will be able to learn along the way and get better at recognizing the faces that it sees in video or images. This is also a method that can be effective when you would like to get it to recognize different animals or recognize a specific item in other images or videos as well.

To help us out here, we need to take a look at some of the advantages that can come with this kind of model with machine learning. One of the advantages that a lot of programmers like with this one is that you can work with this algorithm without having to be in total control over the statistics of the algorithm. Even if you are not working with statistics all of the time, or you are not really familiar with how to use them, you will see that these networks can be used without those statistics, still that if there is any relationship, no matter how complex it is, is inside the information, then it is going to show up when you run the network.

The nice thing with this one is that the relationships inside your data can be found, whether the variables are dependent or independent, and even if you are working with variables that do not follow a linear path. This is great news for those who are just getting started with machine learning because it ensures that we can get a better understanding of how the data relates to each other, and some of the insights that you want to work with, no matter what variables you are working with.

With this in mind, we have to remember that there are still times when we will not use a neural network, and it will not be the solution to every problem that we want to handle in deep learning. One of the bigger issues that come with these neural network algorithms, and why some programmers decide to not use this is that the computing costs are going to be kind of high.

This is an algorithm that is pretty in-depth, and because of this, the computing costs are going to be a bit higher than what we find with some of the other options out there. and for some businesses, and even on some of the projects that you want to do with deep learning, this computation cost will just be too high. It will take on too much power, too much money, and often too much time. For some of the projects that you want to take on, the neural networks will be a great addition to your arsenal with deep learning, and other times, you may want to go another route.

Neural networks are a great option to work with when it is time to expand out your work and when you would like to create a program that can handle some more complex activities. With the right steps here, and with some time to train the neural network, you will find that the neural network is a great way to handle your data and find the trends and predictions that you want.
