🧐 Question
Medium Changed decision boundary	Solve
We have trained a model on a linearly separable training set to classify the data points into 2 sets (binary classification). Our intern recently labelled some new data points which are all correctly classified by the model. All of the new data points lie far away from the decision boundary. We added these new data points and re-trained our model- our decision boundary changed. Which of these models do you think we could be working with? The 2 data sources use SQL Server and have a 3-character CompanyCode column. Both data sources contain an ORDER BY clause to sort the data by CompanyCode in ascending order. Teylor wants to make sure that the Merge Join transformation works without additional transformations. What would you recommend? A: Perceptron B: SVM C: Logistic regression D: Guassion discriminant analysis

Reason #5

Designed for elimination, not selection

The most important thing while implementing the pre-employment Deep Learning Test in your hiring process is that it is an elimination tool, not a selection tool. In other words: you want to use the test to eliminate the candidates who do poorly on the test, not to select the candidates who come out at the top. While they are super valuable, pre-employment tests do not paint the entire picture of a candidate’s abilities, knowledge, and motivations. Multiple easy questions are more predictive of a candidate's ability than fewer hard questions. Harder questions are often "trick" based questions, which do not provide any meaningful signal about the candidate's skillset.

What topics are covered in the Deep Learning Online Test?

Neural Networks
Neural networks are a computational model inspired by biological neural networks. They are composed of layers of interconnected nodes, or artificial neurons, that process and transmit information using weighted inputs. They are measured in this test to assess the understanding of fundamental concepts in deep learning.
Data Normalization
Data normalization is a technique used to standardize the range of data values. It involves transforming the data to have a consistent scale, typically between 0 and 1. This skill is measured in this test to evaluate the ability to preprocess data effectively, which is crucial for training accurate neural networks.
Cost Functions and Activation Functions
Cost functions are used to measure the difference between predicted and actual values in a neural network, guiding the learning process. Activation functions introduce non-linearity to the output of each neuron in a neural network, enabling complex computations. This skill is measured in this test to assess the knowledge of selecting appropriate cost and activation functions for different tasks.
Backpropagation
Backpropagation is a key algorithm for training neural networks. It calculates the gradients of the network's parameters with respect to the loss, allowing for the adjustment of weights in previous layers. This skill is measured in this test to gauge the understanding of how gradients propagate backward through a neural network for efficient learning.
Convolutional Neural Networks
Convolutional neural networks (CNNs) are deep learning models specifically designed for processing structured grid data, such as images. They are built on the idea of convolution, where filters scan and extract local patterns from input data. This skill is measured in this test to evaluate the knowledge of CNN architecture and its application in computer vision tasks.
Recurrent Neural Networks
Recurrent neural networks (RNNs) are neural networks that process variable-length sequential data, such as text or time-series. They have feedback connections that allow information to persist throughout the network. This skill is measured in this test to assess understanding of RNNs and their ability to model sequential patterns.
Generative Adversarial Networks
Generative adversarial networks (GANs) consist of two neural networks: a generator and a discriminator. They are trained together in a competitive process, where the generator aims to produce synthetic data that is indistinguishable from real data. This skill is measured in this test to evaluate knowledge of GAN architecture and its application in generating realistic data.
Natural Language Processing
Natural language processing (NLP) involves the interaction between computers and human language. It encompasses tasks such as speech recognition, text classification, and machine translation. This skill is measured in this test to assess the understanding of NLP techniques and their application in various language-related tasks.
Computer Vision
Computer vision is a branch of artificial intelligence that deals with interpreting visual information from images or videos. It involves tasks like object detection, image recognition, and image segmentation. This skill is measured in this test to evaluate the knowledge of computer vision algorithms and their application in solving visual perception problems.
Transfer Learning
Transfer learning refers to leveraging pre-trained models on one task to improve performance on another task. By utilizing knowledge gained from previous tasks, transfer learning can significantly reduce the amount of training data and time required. This skill is measured in this test to assess the understanding of transferring learned features from one domain to another.
Autoencoders
Autoencoders are neural networks designed to reconstruct the input data from a compressed representation, called the latent space. They are often used for unsupervised learning and dimensionality reduction. This skill is measured in this test to evaluate the knowledge of autoencoders and their application in tasks like data compression and anomaly detection.
Optimization Algorithms
Optimization algorithms play a crucial role in training neural networks by iteratively adjusting the model's parameters to minimize the training loss. Examples include stochastic gradient descent (SGD), Adam, and RMSprop. This skill is measured in this test to assess the familiarity with different optimization algorithms and their impact on network convergence and performance.

Deep Learning Hiring Test FAQs

Can I combine multiple skills into one custom assessment?

Yes, absolutely. Custom assessments are set up based on your job description, and will include questions on all must-have skills you specify. Here's a quick guide on how you can request a custom test.

Do you have any anti-cheating or proctoring features in place?

We have the following anti-cheating features in place:

Non-googleable questions
IP proctoring
Screen proctoring
Web proctoring
Webcam proctoring
Plagiarism detection
Secure browser
Copy paste protection

Read more about the proctoring features.

How do I interpret test scores?

The primary thing to keep in mind is that an assessment is an elimination tool, not a selection tool. A skills assessment is optimized to help you eliminate candidates who are not technically qualified for the role, it is not optimized to help you find the best candidate for the role. So the ideal way to use an assessment is to decide a threshold score (typically 55%, we help you benchmark) and invite all candidates who score above the threshold for the next rounds of interview.

What experience level can I use this test for?

Each Adaface assessment is customized to your job description/ ideal candidate persona (our subject matter experts will pick the right questions for your assessment from our library of 10000+ questions). This assessment can be customized for any experience level.

Does every candidate get the same questions?

Yes, it makes it much easier for you to compare candidates. Options for MCQ questions and the order of questions are randomized. We have anti-cheating/ proctoring features in place. In our enterprise plan, we also have the option to create multiple versions of the same assessment with questions of similar difficulty levels.
