Output

The bug in the provided code is in the `mlp_apply` function, specifically in the softmax activation. The `axis` parameter in the softmax function should be 0, not 1, as we want to apply softmax along the output dimension. Here's the corrected version of the entire code:

The changes made are: 1. In the `mlp_apply` function, changed `axis=1` to `axis=-1` in the softmax activation. This ensures that softmax is applied along the last dimension (output dimension) for each sample in the batch. 2. In the example usage, changed `print(list(y.flatten().sum(1)))` to `print(y.sum(axis=-1))`. This correctly sums the probabilities for each sample along the output dimension. These changes ensure that the softmax is applied correctly, and the sum of probabilities for each sample in the batch is 1, as expected for a probability distribution.

This directly computes the sum along the feature axis for each sample in the batch, which should be close to 1 for each sample after softmax. These changes ensure that the softmax is applied correctly and that the output sums are computed as intended. The result should now be a 1D array of values very close to 1, one for each sample in the input batch.

Output

The bug in the provided code is in the `mlp_apply` function, specifically in the softmax activation. The `axis` parameter in the softmax function should be 0, not 1, as we want to apply softmax to each row independently. Here's the corrected version of the entire code:

    b1 = jnp.zeros(hidden_size)
    # Initialize weights and biases for the second linear layer
    w2 = jax.random.normal(k2, (output_size, hidden_size)) * jnp.sqrt(2.0 / hidden_size)
    b2 = jnp.zeros(output_size)
    return {'w1': w1, 'b1': b1, 'w2': w2, 'b2': b2}

def mlp_apply(params, x):
    # First linear layer
    x = jnp.dot(x, params['w1'].T) + params['b1']
    # Relu activation
    x = jax.nn.relu(x)
    # Second linear layer

    # Softmax activation

# Example usage:

y = mlp_apply(params, x)
print(y.sum(axis=1))  # The output sum should be very close to [1, 1, 1, 1, 1]
The changes made are: 1. In the `mlp_apply` function, changed `axis=1` to `axis=-1` in the softmax function. This ensures that softmax is applied along the last axis, which is correct for row-wise operations. 2. In the example usage, changed `print(list(y.flatten().sum(1)))` to `print(y.sum(axis=1))`. This directly computes the sum along each row, which is what we want to check for the softmax output. These changes should resolve the issue and produce the expected output, where the sum of probabilities for each sample (row) is very close to 1.

The changes made are: 1. In the `mlp_apply` function, changed `axis=1` to `axis=-1` in the softmax function. This ensures that the softmax is applied along the last axis (which is equivalent to axis=1 in this case, but more general). 2. In the example usage, changed `print(list(y.flatten().sum(1)))` to `print(y.sum(axis=1))`. This correctly sums along the second axis (axis=1) for each sample, giving us the sum of probabilities for each sample. These changes ensure that the softmax is applied correctly to each sample's output, and the sum of probabilities for each sample is computed correctly. The output should now be very close to [1, 1, 1, 1, 1] as expected.
