Output

The bug in the code is in the initialization of the weights for the first linear layer. The weights should be multiplied by `sqrt(2.0 / input_size)` instead of `sqrt(2.0 / hidden_size)`. Here is the corrected version of the code:

Also, in `mlp_apply` function, the `x` should be transpose before passing it to `jnp.dot` and `params['w1']` and `params['w2']` should not be transpose.

Output

The issue in the code is that the weights in the first linear layer are being initialized with the incorrect square root factor. The correct initialization should be: `w1 = jax.random.normal(k1, (hidden_size, input_size)) * jnp.sqrt(2.0 / hidden_size)` Also, the dot product should be computed as `jnp.dot(params['w1'], x) + params['b1']` instead of `jnp.dot(x, params['w1'].T) + params['b1']`.

Output

The bug in the current implementation is in the weight initialization for the first linear layer. The weights are being multiplied by `sqrt(2.0 / input_size)` instead of `sqrt(2.0 / hidden_size)`. This is a common mistake when initializing the weights for a neural network. Here's the corrected version of the code:

Note that in the corrected version, the line initializing `w1` has been updated to use `hidden_size` instead of `input_size`. This ensures that the weights are properly initialized with the correct scaling factor. Also note that the weight initialization for the second linear layer already uses the correct scaling factor (`sqrt(2.0 / hidden_size)`). This is because the input size for the second linear layer is the size of the hidden layer, so the scaling factor is based on the hidden size as well.

Output

I believe there is a bug in the `init_mlp_params` function where the factor used in initializing the weights is incorrect. It should be `1 / np.sqrt(fan_in)` for the first layer and `1 / np.sqrt(fan_out)` for the second layer, where `fan_in` and `fan_out` are the number of input and output neurons, respectively. Here's the corrected version of the code:

    return {'w1': w1, 'b1': b1, 'w2': w2, 'b2': b2}

Note that the factor used in initializing the weights is `1 / np.sqrt(fan_in)` for the first layer and `1 / np.sqrt(fan_out)` for the second layer, as recommended in the paper "Delving Deep into Rectifiers: Surpassing Human-Level Performance on ImageNet Classification" by He et al. (2015). This is also the default initialization scheme used in many deep learning frameworks such as TensorFlow and PyTorch.

Output

I see one potential issue in the implementation of the `init_mlp_params` function. The weights initialization formula seems to be using the input size for both linear layers. I believe the second layer should use the hidden size for its weight initialization. Here's the corrected code:

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]
Now, the second linear layer should be correctly initialized using the hidden size instead of the input size.
