The bug was in the `mlp_apply` function, specifically in the `jax.nn.softmax(x, axis=1)` line. The axis should be `-1` instead of `1`. Here's why: * **Softmax along the correct axis:** The softmax function normalizes the input along a specific axis, ensuring the values sum up to 1. In this case, we want to apply softmax to each row of the output (representing the probabilities for each of the 30 output classes). Since each row corresponds to the last axis of the output array, we should use `axis=-1`. By changing the axis to `-1`, the code now correctly calculates the softmax probabilities for each output class, and the sum along each row should be very close to 1.

Here's a breakdown of the changes and why they were necessary: 1. **Matrix Multiplication and Broadcasting:** - In the original `mlp_apply` function, the matrix multiplications `jnp.dot(x, params['w1'].T)` and `jnp.dot(x, params['w2'].T)` were performed incorrectly. The order of matrix multiplication matters. - Additionally, we need to ensure the bias terms (`b1` and `b2`) are broadcasted correctly during addition. We reshape the bias terms to be column vectors using `.reshape(-1, 1)` so they can be added to the result of the matrix multiplication. 2. **Softmax Axis:** - The `axis` parameter in `jax.nn.softmax` was set to `1`. To get the sum of each row close to 1, the softmax should be calculated along the correct axis (axis `0` in the modified code) and then transposed to match the desired output shape. With these corrections, the code now performs the matrix operations and softmax calculation as intended, producing the expected output where the sum of each row in `y` is approximately 1.

**Explanation of the bug fix:** The original code had an error in the matrix multiplication order within the `mlp_apply` function. In JAX, when performing matrix multiplication with `jnp.dot`, the order of the matrices matters. Here's the breakdown of the fix: 1. **Original (Incorrect) Lines:** 
1
2
3
   x = jnp.dot(x, params['w1'].T) + params['b1']
   x = jnp.dot(x, params['w2'].T) + params['b2']
- These lines were performing the dot product in the wrong order. Since `x` represents the input data and `w1` (and `w2`) represent the weight matrices, the multiplication should be `jnp.dot(weights, input)` to ensure the correct dimensions for matrix multiplication. 2. **Corrected Lines:** 
1
2
3
   x = jnp.dot(params['w1'], x.T).T + params['b1'] 
   x = jnp.dot(params['w2'], x.T).T + params['b2']
- We first transpose `x` using `.T` to align the dimensions correctly for matrix multiplication with the weight matrices (`params['w1']` and `params['w2']`). - After the dot product, we transpose the result again using `.T` to get back the original shape of `x`. By fixing the order of matrix multiplication, the code now correctly implements the forward pass of the MLP network, and the output sums should be close to 1 as expected for a softmax output.

The bug was in the matrix multiplication within the `mlp_apply` function. In JAX, when performing matrix multiplication with `jnp.dot`, the order of the matrices matters. Here's the breakdown of the fix: 1. **Original (Incorrect):** - `x = jnp.dot(x, params['w1'].T) + params['b1']` - `x = jnp.dot(x, params['w2'].T) + params['b2']` The issue here is that we're transposing the weight matrices (`params['w1'].T`, `params['w2'].T`) before multiplication. This leads to incorrect dimensions for the dot product, causing errors or unexpected results. 2. **Corrected:** - `x = jnp.dot(params['w1'], x.T).T + params['b1']` - `x = jnp.dot(params['w2'], x.T).T + params['b2']` In the corrected code: - We first transpose the input `x` (`x.T`) to align the dimensions correctly for matrix multiplication with the weight matrices. - We perform the dot product with the weight matrix (`params['w1']` or `params['w2']`). - We transpose the result back (`(...).T`) to get the output in the desired shape. By fixing the matrix multiplication order, the code now performs the forward pass of the MLP correctly.

**Explanation of the bug fix:** The original code had an error in the matrix multiplication within the `mlp_apply` function. In both linear layers, the order of multiplication and transposition was incorrect, leading to a shape mismatch. Here's the breakdown of the correction: 1. **Original:** `jnp.dot(x, params['w1'].T) + params['b1']` 2. **Corrected:** `jnp.dot(params['w1'], x.T).T + params['b1']` - We now multiply the weight matrix (`params['w1']`) with the transpose of the input (`x.T`). - The result is then transposed back `.T` to match the expected shape for the next layer. This correction ensures that the matrix multiplication aligns with the dimensions of the weight matrix and the input data, resolving the shape mismatch and allowing the MLP to function correctly.
