In the `mlp_apply` function, the lines: 
1
2
x = jnp.dot(x, params['w1'].T) + params['b1']
x = jnp.dot(x, params['w2'].T) + params['b2']
have been changed to: 
1
2
x = jnp.dot(x, params['w1']) + params['b1']
x = jnp.dot(x, params['w2']) + params['b2']
Additionally, the `jax.nn.softmax` function has been updated to use the `axis=-1` argument instead of `axis=1`. This ensures that the softmax operation is applied across the last dimension of the input tensor, which is the appropriate behavior for classification tasks. With these changes, the code should now work as expected.

The bug in the provided code is in the `mlp_apply` function, where the weight matrices (`params['w1']` and `params['w2']`) are being transposed incorrectly during the matrix multiplication operations. The correct code should be:

Explanation: 1. In the `init_mlp_params` function, the weight matrices `w1` and `w2` are initialized correctly. 2. In the `mlp_apply` function, the matrix multiplication operations for the linear layers should not transpose the weight matrices. The correct way to perform the linear transformations is `jnp.dot(x, params['w1'])` and `jnp.dot(x, params['w2'])`. 3. Additionally, the `jax.nn.softmax` function applies the softmax activation along the last dimension by default. To ensure the softmax is applied across the output dimensions, we explicitly specify `axis=-1`. 4. In the example usage, we print the sum of the output values along the last dimension (output dimension) using `y.sum(axis=-1)`. The sum should be very close to 1 for each sample, as the softmax activation normalizes the output to sum to 1 across the output dimension. With these changes, the code should work correctly.

The bug in the provided code is that the weight matrices are transposed incorrectly during the forward pass (`mlp_apply`). Here's the corrected version:

y = mlp_apply(params, x)
print(list(y.flatten().sum(1)))  # The output sum should be very close to [1, 1, 1, 1, 1]
In the corrected version, the weight matrices `w1` and `w2` are initialized with the correct shapes, and the forward pass (`mlp_apply`) multiplies the input `x` with the weight matrices without transposing them. The output sum should now be very close to `[1, 1, 1, 1, 1]`, as expected for a softmax output.

def mlp_apply(params, x):
    # First linear layer
    x = jnp.dot(x, params['w1']) + params['b1']
    # Relu activation

The changes made are: 1. In the `init_mlp_params` function, the dimensions of the weight matrices are corrected. The first weight matrix `w1` has dimensions `(input_size, hidden_size)`, and the second weight matrix `w2` has dimensions `(hidden_size, output_size)`. 2. In the `mlp_apply` function, the weight matrices are multiplied with the input in the correct order. Instead of using `jnp.dot(x, params['w1'].T)`, we use `jnp.dot(x, params['w1'])` for the first linear layer, and `jnp.dot(x, params['w2'])` for the second linear layer. 3. The softmax activation in `mlp_apply` is applied along the last axis (`axis=-1`) instead of the second axis (`axis=1`). This is a more common convention for multi-class classification tasks. With these changes, the output sum of the softmax activations should be very close to `[1, 1, 1, 1, 1]`, as expected for valid probability distributions.

Fix the bug in this jnp function. Write out the full correct version of the code. import jax import jax.numpy as jnp def init_mlp_params(input_size, hidden_size, output_size, key): k1, k2 = jax.random.split(key) # Initialize weights and biases for the first linear layer w1 = jax.random.normal(k1, (hidden_size, input_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, (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 x = jnp.dot(x, params['w2'].T) + params['b2'] # Softmax activation return jax.nn.softmax(x, axis=1) # Example usage: key = jax.random.PRNGKey(0) params = init_mlp_params(10, 20, 30, key) x = jax.random.normal(key, (5, 10)) # random input similar to torch.randn y = mlp_apply(params, x) print(list(y.flatten().sum(1))) # The output sum should be very close to [1, 1, 1, 1, 1]

Output

The bug in the provided code is in the `mlp_apply` function, where the matrix multiplication for the second linear layer is performed incorrectly. The weight matrix `params['w2']` needs to be transposed before the matrix multiplication with the input `x`. Here's the corrected version of the code:

def init_mlp_params(input_size, hidden_size, output_size, key):
    k1, k2 = jax.random.split(key)
    # Initialize weights and biases for the first linear layer
    w1 = jax.random.normal(k1, (hidden_size, input_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, (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
    x = jnp.dot(x, params['w2']) + params['b2']  # Corrected line
    # Softmax activation
    return jax.nn.softmax(x, axis=1)

# Example usage:
key = jax.random.PRNGKey(0)
params = init_mlp_params(10, 20, 30, key)
x = jax.random.normal(key, (5, 10)) # random input similar to torch.randn
y = mlp_apply(params, x)
print(list(y.flatten().sum(1)))  # The output sum should be very close to [1, 1, 1, 1, 1]
In the corrected `mlp_apply` function, the line `x = jnp.dot(x, params['w2'].T) + params['b2']` has been changed to `x = jnp.dot(x, params['w2']) + params['b2']`. This change ensures that the weight matrix `params['w2']` is not transposed when multiplied with the input `x`. With this correction, the output of the example usage should have the sum of the softmax outputs for each sample very close to 1, as expected.
