Sample answers to questions for an interview with a scientist who looks at pictures
These examples of questions and answers for job interviews will help you prepare for a meeting with a hiring manager:
1. Could you tell me what overfitting is and how to fix it?
In machine learning, this is a common area of study. The question is meant to find out how much you know about data modeling. In two parts, the question asks you to describe a problem and suggest ways to solve it. An interviewer can find out how well you know your field and how to solve problems by asking you this kind of question.
Example: “When the model is too narrow and doesn’t fit the whole, this is called “overfitting.” The model has a lot of specific details, but it doesn’t show the overall patterns and trends in the data. Some signs of overfitting are when the training set is accurate but it is hard to predict how accurate the test set will be. Often, the test set is much less accurate than the training set. This could be a sign that the model needs to be changed.
Recalibrating the model to make it more general can fix overfitting. Instead of having the model focus too much on the details, you focus on the big picture. Adding more data is one way to fix overfitting. If you get more information, you might be able to figure out what’s wrong. You could also fix overfitting by making changes to the model. Maybe the model is too hard to understand, and because of that, it focuses on the wrong things. In this kind of situation, you might be able to fix overfitting by trying a simpler model.”
What does it mean to segment an image, and why do we need to do it?
This is a straightforward question about how to look at pictures. The interviewer wants to know how much you know about this topic and if you have ever worked with image segmentation. In a good answer, you can talk about your own experiences and give examples to show how well you know something.
Example: “Image segmentation is the process of breaking up an image into smaller pieces. You can make it easier to look at and understand an image by using image segmentation. The first step in figuring out what an image is about is to segment it. It might be hard to do more analysis without image segmentation.
I worked for a big cell phone company, where I helped make software that could recognize faces. The software used image segmentation to break up faces into smaller pictures that focused on different parts of the face. By doing this, the device can figure out which parts of the owner’s face make up its image. The software can also tell if a person doesn’t have that set of features, which stops someone else from using the phone.”
3.What is an image processing algorithm?
This type of question checks how well you understand and know processing algorithms. As a scientist who studies how images are put together, you have to use algorithms all the time. Even though algorithms are a big topic, you can still talk about how they are used and why they are important to the field.
Example: “There are many different kinds of algorithms used in image processing. An algorithm is just a list of rules that a computer follows to solve a problem. Setting parameters in an algorithm tells a computer how to do an analysis. This makes image processing possible. For example, algorithms for processing images can be used to find edges, improve contrast, find features, and do morphological operations. All of these things can tell a computer what to look for in an image.
You can use algorithms that already exist, but people make new algorithms every day or change algorithms that already exist to fit their needs. It really depends on what you want to do with the pictures and how you want to process them. In the end, we can analyze and process images much better because we have so many different kinds of algorithms.”
What does computer vision mean? What are the pros and cons of it?
This question is meant to see if you know what it means to be a good image analysis scientist in a key way. The interviewer is trying to find out how familiar you are with the idea by asking you about its pros and cons.
Example: “Computer vision lets computers look at pictures and figure out what they are. AI and machine learning have made it easier for computer vision to get, process, and analyze images on a large scale. When you use computer vision to process images, you can run through a lot more images than you could if a professional did the analysis. Computer vision also works well. After you tell the computer how to do the analysis, it does it.
Computer vision costs money, which is one of its problems. Most of the time, AI and machine learning can’t work without a team of experts. Another possible problem is that you have to keep an eye on how the system works and find any bugs. Even though computer vision has come a long way, it still has trouble seeing images that are close to other images. This is why people can get into websites that don’t want machines to get in by passing image tests.”
5. What does it mean to classify an image based on its place in time?
This question is about computer vision and a higher level of technical knowledge about how to process and analyze images. Before you talk about some of your own experiences and examples with image classification, you should explain what it is.
Example: “Computer vision uses a type of pattern recognition called “contextual image classification.” The system basically sorts images into groups based on what the computer knows about their context. For example, to figure out what’s going on, the system looks at the pixels in an image and the pixels around it. If you want to analyze pictures of houses, the computer can tell which picture is the house and which is the scenery around it by looking at the edges and pixels that are close to it.
Segmentation, on the other hand, doesn’t take context into account and can sometimes lead to unwanted changes in the data. When I worked on a project that needed a detailed analysis of images, we used contextual image classification to get rid of images and data that weren’t important to the project.”
