It is OK to have double images when training an AI model?

Each class (happy or sad) should have at least 20 pictures?

With machine learning computers learn the solution by finding patterns in data?

Bias happens in machine learning when our human biases becomes part of the technology we create?

Interaction bias can occur when people are asked to draw shoes as an example, for a computer to train. As more people interact with the computer, the computer may not recognize some peoples images ensuing in interaction bias?

Latent bias can occur when training a computer on what a physicist looks like, and pictures of past physicists are used. An algorithm will end up with a latent bias skewing towards men?

In order to prevent Selection bias from occurring when training a model to recognize faces, images from the internet and photo libraries which represent everyone must be used?

Technology can work for everyone if we are all aware of the biases and become part of the conversation to prevent the biases from happening?

An Emotion AI is a tool that can capture and analyze human emotions expressed in writing, spoken word, in a photo, or video?

Facial recognition is an AI tool that can recognize a specific person in a photo or video regardless of the emotional expression and across all ages?

New technology and innovation can bring solutions and unintended consequences. An example - Smart robots can take on dangerous tasks where strength, endurance, and problem solving are needed. However, they can also be used to commit crimes?

Driverless cars use machine learning (AI) to identify road signs and other things they encounter on the road like pedestrians and vehicles?

When training a computer to recognize road signs, it is important to provide it with a diverse set of training data in order to prevent bias. For example: pictures taken in different locations, at different times of day, and in different weather conditions?

With machine learning, programmers use a type of program called a neural network that functions more like a human brain?

In the Rubberband car project, the simple machine used is the _____ and _____. When you wind up the car's axle, you stretch the rubberband and store _________ energy. When the rubberband is released, it starts to unwind. The _________ energy is converted to _______ energy as the car is propelled forward.

In real cars, gasoline's chemical energy or the electrical energy in a battery is converted to kinetic energy of the moving car?

What is the most efficient way to duplicate the top portion of the shape (shown in red) to the bottom portion (shown in green)?

What is the most efficient way to place the UCS on the rubberband car's front right wheel, so that 6 holes can be knocked out as shown in the picture?

What was one of the constraints in designing and 3D printing the rubberband car model?
