8. Linear Classification Here is a question to keep in mind as we go through the contents of this video. In logistic regression, when applied to classification, on what basis is the predicted output label selected? Again, what is the basis used by our logistic regressor in order to decide which output label to assign […]

6. Lab: Multiple Regression in TensorFlow At the end of this lecture, you should have a good idea of what are some of the decisions that you need to make while training a machine learning model. These decisions will affect the parameters that you use during the training process. In this lecture, we’ll implement a […]

4. Gradient Descent Here is a question that I’d like you to try and attempt and keep in mind as we go through the contents of this video. What’s the difference between stochastic gradient descent and minibatch gradient descent? As the names would suggest, these are very closely related types of optimization. What is the […]

1. Lab: Access Data from Yahoo Finance The remaining demos that we’ll see, which involve practical examples of using regression models in the real world, will all use data from Yahoo. Finance. So you can go ahead and download the latest data from Finance@yahoo. com. This lecture, I’ll quickly walk you through the files that […]

4. Rightsizing Recommendations We cover two last bits about VMs before we move on to images. The first of these is right sizing recommendations. You’ve instantiated your machines and you’ve started your workloads, and you’re serving production traffic. But how do you know that this machine type is the right one for you? How do […]

1. Live Migration We’ve studied VMs in a fair bit of depth, but there’s still a bunch of stuff that we need to know about VMs in order to understand GCP’s platform completely. In this section, we’ll study some advanced features of VMs that we haven’t seen before, and we’ll also look at images. Images […]

3. pkill, killall Another way of sending signals to processes is the pkill command. It works in a similar way to kill. However, no process IDs have to be passed, but only the names of the corresponding processes. So theoretically pkill signal and than the name and not the process ID. The standard signal from […]

1. ps, top, uptime, free The following lessons are about processes and how to monitor, terminate or recreate them. Let’s first look at the most important command. That is the ps command. I’ve used this one or the other time in the last few lessons without going into detail. ps stands for Processes and shows […]

1. nice, renice, ps, top This lesson is about the socalled Nice value, which I mentioned in previous videos. To explain the Nice value, maybe let’s open Top and in the fourth column from the left here in this one we see the Nice value. It is a priority given to a process. The better […]

1. regex, grep, egrep, fgrep This lesson is about the so called regular expressions, or Regex for short. Regular expressions are search patterns that are used to search through the contents of files. You can roughly compare Regex with the file globing. Although Regex is much more versatile and much more powerful. We already got […]
