The main corrections are: 1. In the `mlp_apply` function, the matrix multiplication was incorrect. When using `jnp.dot()`, you need to ensure the dimensions are compatible. - Changed `jnp.dot(x, params['w1'].T)` to `jnp.dot(params['w1'], x.T).T` - Similarly for the second layer: `jnp.dot(params['w2'], x.T).T` 2. In the final print statement, changed `y.flatten().sum(1)` to `y.sum(1)` since softmax already ensures the rows sum to 1. These changes ensure that: - The matrix multiplications are done correctly - The dimensions align properly - The softmax is applied along the correct axis The code now correctly implements a simple MLP (Multi-Layer Perceptron) with ReLU activation in the hidden layer and softmax activation in the output layer. When you run this code, you should see an output of approximately `[1, 1, 1, 1, 1]`, indicating that each row of the output sums to 1, which is a property of the softmax function.

The key changes are: 1. In the `mlp_apply` function, I corrected the matrix multiplication. The original code was incorrect because: - `jnp.dot(x, params['w1'].T)` does not match the weight matrix dimensions - The correct approach is to use `jnp.dot(params['w1'], x.T).T` to ensure proper matrix multiplication 2. Similarly for the second layer, use `jnp.dot(params['w2'], x.T).T` 3. Changed the final print statement to `y.sum(1)` to sum along axis 1 (rows) These changes ensure that: - The matrix multiplications are done correctly - The dimensions of the weights and inputs match - The softmax is applied correctly - The output sums to 1 for each row The corrected version will now work as expected, with the output probabilities summing to 1 for each input.

The key corrections are: 1. In the matrix multiplication for the first and second linear layers, I changed `jnp.dot(x, params['w1'].T)` to `jnp.dot(params['w1'], x.T).T`. This ensures the matrix multiplication is done correctly given the shapes of the weights and input. 2. Similarly for the second linear layer, changed `jnp.dot(x, params['w2'].T)` to `jnp.dot(params['w2'], x.T).T`. 3. When checking the sum, changed `y.flatten().sum(1)` to `y.sum(1)` since the output is already a 2D array. These changes ensure that: - The matrix multiplications are performed with the correct matrix orientations - The dimensions match for each operation - The softmax is applied correctly - The sum of probabilities across each row is very close to 1 The rest of the code remains the same. This version should now work correctly with JAX's linear algebra operations and matrix shapes.

The main corrections are: 1. In the `mlp_apply` function, the matrix multiplication order was incorrect. In JAX, when matrix multiplying a matrix `A` with dimensions (m, n) and a matrix `B` with dimensions (n, k), you do `jnp.dot(A, B)`. 2. So for the first linear layer, it should be `jnp.dot(params['w1'], x.T).T + params['b1']` - `x.T` transposes the input - The result is then transposed back - This ensures the matrix multiplication is done correctly 3. The same change is made for the second linear layer. 4. In the final print statement, `y.flatten().sum(1)` was changed to `y.sum(1)` since softmax already operates along the last axis. These changes ensure that the matrix multiplications are done correctly, maintaining the expected dimensions and preserving the softmax normalization along the correct axis. The output will show that each row of the softmax output sums to 1, which is a key property of the softmax function.
