Output

The bug in the original code is in the way the summation of the output is being computed. Specifically, the `flatten().sum(1)` operation is incorrect for summing the output probabilities since the output of the softmax function is already a 2D array where each row represents the output probabilities for each input. Instead, we want to sum across the columns (for each row) to check that the output probabilities sum to 1. Here is the corrected version of the code:

    w1 = jax.random.normal(k1, (input_size, hidden_size)) * jnp.sqrt(2.0 / input_size)
    b1 = jnp.zeros(hidden_size)
    # Initialize weights and biases for the second linear layer
    w2 = jax.random.normal(k2, (hidden_size, output_size)) * jnp.sqrt(2.0 / hidden_size)

    x = jnp.dot(x, params['w1']) + params['b1']
    # Relu activation

    # Second linear layer

# Correctly summing the output probabilities along the correct axis
output_sums = y.sum(axis=1)
print(output_sums)  # The output sum should be very close to [1, 1, 1, 1, 1]
### Key Corrections: 1. **Weight Initialization**: The dimensions of the weights were corrected to `(input_size, hidden_size)` for `w1` and `(hidden_size, output_size)` for `w2` to match the input and output shapes correctly. 2. **Dot Product Order**: The order of the arguments in `jnp.dot` was corrected to ensure proper matrix multiplication; specifically, `jnp.dot(x, params['w1'])` and `jnp.dot(x, params['w2'])`. 3. **Output Summation**: The summation of the output probabilities was changed to `y.sum(axis=1)` to ensure that we are summing across the classes (columns) for each input (row). With these corrections, the function should work as intended, and the output sums should be very close to `[1, 1, 1, 1, 1]`, indicating that the softmax outputs are valid probability distributions.

Output

The issue in the provided code arises from the way the output sum is calculated in the print statement. The `flatten()` method is applied to the entire output tensor, which does not give the expected result. Instead, the sum should be computed for each row of the output tensor individually. Here's the corrected version of the code:

Output

The provided code has a bug in the way the output is printed. The `flatten().sum(1)` will raise an error because `flatten()` converts the array into a 1D array, and then attempting to sum along axis 1 is invalid since a 1D array has no such axis. Instead, we should sum along axis 0 to ensure that each row sums to 1 after applying softmax. Here is the corrected version of the code:

### Key Changes Made: 1. **Changed the print statement:** Instead of `list(y.flatten().sum(1))`, I changed it to `y.sum(axis=1)`, which correctly sums the softmax outputs for each row. Each row should sum to 1, confirming that the softmax operation was correctly applied. 2. **Removed unnecessary `list()` conversion:** The output of `y.sum(axis=1)` is already a JAX array, and converting it to a list is not necessary for validating the result.

Output

The code you provided has a small bug in the final print statement. The `flatten()` function returns a 1D array, and summing along axis 1 in that case will raise an error since there is no axis 1 in a 1D array. The correct way to check if the output of the softmax is summing to 1 for each sample is to sum along the correct axis (which is 0 for a 2D array). Here’s the corrected code with all the necessary parts included:

y = mlp_apply(params, x)

# Correctly summing the output across the right axis
print(y.sum(axis=1))  # The output sum should be very close to [1, 1, 1, 1, 1]
### Key Changes: 1. The `print` statement now uses `y.sum(axis=1)` to correctly sum the outputs of the softmax along the right axis. 2. I used `axis=-1` in the softmax function for clarity and to ensure it sums along the last dimension, which is typically more readable. This corrected code should work as intended, and the output sums for each of the samples should be very close to 1.

Output

The code you provided has a minor bug in the way the output is printed. The `flatten().sum(1)` operation is not correctly applied because `flatten()` returns a 1-D array, and then calling `sum(1)` on it does not make sense. Instead, you should sum along the appropriate axis for your output. Here's the corrected version of the code:

y = mlp_apply(params, x)
print(y.sum(axis=1))  # The output sum should be very close to [1, 1, 1, 1, 1]
### Changes made: 1. Changed `print(list(y.flatten().sum(1)))` to `print(y.sum(axis=1))` to correctly sum across the appropriate axis of the output array, since `y` is a 2D array where each row corresponds to a different input sample and each column corresponds to a class. The output of `softmax` should sum to 1 for each input sample.
