Why do we shuffle the "buys" and "sells" lists after balancing them in the context of building a recurrent neural network for predicting cryptocurrency price movements?
Shuffling the "buys" and "sells" lists after balancing them is a important step in building a recurrent neural network (RNN) for predicting cryptocurrency price movements. This process helps to ensure that the network learns to make accurate predictions by avoiding any biases or patterns that may exist in the sequential data.
When training an RNN, it is common to balance the dataset to prevent the model from being biased towards predicting one class over the other. In the context of cryptocurrency price movements, the "buys" and "sells" represent two different classes or labels. By balancing the dataset, we aim to have an equal representation of both classes, which helps the model learn to make predictions without favoring one class over the other.
However, if we were to balance the dataset and feed it directly into the RNN without shuffling, the model might still learn some unwanted patterns or biases. For example, if the "buys" were always listed before the "sells" in the original dataset, the model might learn to associate certain patterns or features with the "buys" class and others with the "sells" class. This could lead to inaccurate predictions when faced with real-world data where the order of "buys" and "sells" may vary.
Shuffling the balanced dataset helps to eliminate any potential biases or patterns that may exist due to the original order of the data. By randomly reordering the "buys" and "sells" lists, we ensure that the model learns to focus on the relevant features and patterns rather than relying on the order of the data. This enhances the generalization capability of the model and allows it to make accurate predictions on unseen data.
To illustrate this point, let's consider a simplified example. Suppose we have a dataset with 100 "buys" and 100 "sells" samples. If we balance the dataset by randomly selecting 100 samples from each class, we would end up with a balanced dataset of 200 samples. Now, if we shuffle this dataset, the order of the "buys" and "sells" samples will be randomized. This randomness ensures that the model cannot rely on the order of the data and must learn the underlying patterns and features instead.
Shuffling the "buys" and "sells" lists after balancing them is a important step in building an accurate RNN for predicting cryptocurrency price movements. It helps to eliminate biases and patterns that may exist due to the original order of the data, allowing the model to focus on the relevant features and make accurate predictions on unseen data.
