Impact of Base Value on Frequency Parameters
In the formula for calculating frequency parameters, θ_k = 10000^(-2(k-1)/d), a researcher proposes changing the base from 10000 to 500. Briefly explain the primary effect this modification would have on the generated frequencies and the potential impact on the model's ability to encode relative positional information.

An engineer is implementing a transformer model with an embedding dimensionality of
d = 512. For the positional information, they use a method where frequency parametersθ_kare calculated using the formula:θ_k = 10000^(-2(k-1)/d). What is the correct value for the frequency parameterθ_kwhere the component index isk = 129?Consider the formula for calculating frequency parameters in a positional embedding scheme:
θ_k = 10000^(-2(k-1)/d), wheredis the embedding dimension andkis the component index. According to this formula, as the component indexkincreases, the value of the frequency parameterθ_kalso increases.Impact of Base Value on Frequency Parameters
