Question

read the excerpt from \a computer can now translate languages as well as a human.\

deep learning software simulates this layered structure with an artificial neural network that enables computers to learn to solve problems through examples. to do this, a program maps out a set of virtual neurons then assigns random numerical values, called weights, to connections between them. these weights determine how each simulated neuron responds to digitized features.

which entry in the dictionary supports the meaning of the word weights as used in the excerpt?

weight | wāt | noun

1. the amount that an object weighs
2. the relative importance given something
3. a state of being clumsy due to size
4. an overpowering force

Explanation:

Analyze the context of the word in the excerpt

Using the Vocabulary in Context knowledge point, we examine how "weights" is used in the text: "...assigns random numerical values, called weights, to connections between them. These weights determine how each simulated neuron responds to digitized features." Here, "weights" refers to numerical values assigned to connections to determine their influence or response level.

Evaluate the dictionary definitions

Using the Context Clues knowledge point, we compare the context with the provided dictionary entries:

1. "the amount that an object weighs" — This refers to physical heaviness, which does not fit numerical values in a computer program.
2. "the relative importance given something" — In neural networks, numerical weights represent the strength or relative importance of a connection in determining the output. This fits the context perfectly.
3. "a state of being clumsy due to size" — This is irrelevant to the technical context.
4. "an overpowering force" — This does not match the description of assigned numerical values.

Select the correct entry

Definition 2 is the only entry that accurately supports the meaning of "weights" as numerical values determining connection strength or importance in the neural network.

Answer:

• 1. the amount that an object weighs
• 2. the relative importance given something (Correct answer)
• 3. a state of being clumsy due to size
• 4. an overpowering force
