This minimizes computation and parameters.\n   - Notation: $s_{1x1}$ is the number of 1x1 filters in the squeeze layer.\n\n2. **Expand Layer**: A mix of 1x1 and 3x3 convolution filters.\n   - Purpose: Capture both local details (3x3) and pointwise features (1x1).\n   - Notation:\n     - $e_{1x1}$: Number of 1x1 filters in expand layer.\n     - $e_{3x3}$: Number of 3x3 filters in expand layer.\n   - The outputs of these two parallel convolutions are concatenated along the channel dimension.\n\n### Operation\n\nThe flow is:\n`Input -> Squeeze (1x1 conv + ReLU) -> Expand ( (1x1 conv + ReLU) || (3x3 conv + ReLU) ) -> Concatenate -> Output`\n\n### Why it works?\n\nStandard 3x3 convolution on $C_{in}$ channels with $C_{out}$ filters has parameters:\n$P_{standard} = 3 \\times 3 \\times C_{in} \\times C_{out}$\n\nIn Fire Module:\n\n1. Squeeze layer reduces $C_{in}$ to $s_{1x1}$ (small). Parameters: $1 \\times 1 \\times C_{in} \\times s_{1x1}$.\n2. Expand 3x3 layer operates on only $s_{1x1}$ channels. Parameters: $3 \\times 3 \\times s_{1x1} \\times e_{3x3}$.\n3. Expand 1x1 layer adds more features cheaply. Parameters: $1 \\times 1 \\times s_{1x1} \\times e_{1x1}$.\n\nTotal parameters are significantly lower if $s_{1x1} \\ll C_{in}$.\n\n### Implementation Details\n\n- **Padding**: Use 'same' padding for 3x3 convolutions so spatial dimensions match 1x1 outputs.\n- **Concatenation**: Join along the channel axis (axis=-1 or 1 depending on format, here we assume (H, W, C)).",

+## SqueezeNet Fire Module Explained
+
+SqueezeNet achieves AlexNet-level accuracy with 50x fewer parameters through its "Fire Module".
+
+### Architecture
+
+The Fire Module consists of two layers:
+
+1. **Squeeze Layer**: A convolution layer with only 1x1 filters.
+   - Purpose: Reduce the number of input channels before feeding them to larger 3x3 filters. This minimizes computation and parameters.
+   - Notation: $s_{1x1}$ is the number of 1x1 filters in the squeeze layer.
+
+2. **Expand Layer**: A mix of 1x1 and 3x3 convolution filters.
+   - Purpose: Capture both local details (3x3) and pointwise features (1x1).
+   - Notation:
+     - $e_{1x1}$: Number of 1x1 filters in expand layer.
+     - $e_{3x3}$: Number of 3x3 filters in expand layer.
+   - The outputs of these two parallel convolutions are concatenated along the channel dimension.
+
+### Operation
+
+The flow is:
+`Input -> Squeeze (1x1 conv + ReLU) -> Expand ( (1x1 conv + ReLU) || (3x3 conv + ReLU) ) -> Concatenate -> Output`
+
+### Why it works?
+
+Standard 3x3 convolution on $C_{in}$ channels with $C_{out}$ filters has parameters:
+$P_{standard} = 3 \times 3 \times C_{in} \times C_{out}$
+
+In Fire Module:
+
+1. Squeeze layer reduces $C_{in}$ to $s_{1x1}$ (small). Parameters: $1 \times 1 \times C_{in} \times s_{1x1}$.
+2. Expand 3x3 layer operates on only $s_{1x1}$ channels. Parameters: $3 \times 3 \times s_{1x1} \times e_{3x3}$.
+3. Expand 1x1 layer adds more features cheaply. Parameters: $1 \times 1 \times s_{1x1} \times e_{1x1}$.
+
+Total parameters are significantly lower if $s_{1x1} \ll C_{in}$.
+
+### Implementation Details
+
+- **Padding**: Use 'same' padding for 3x3 convolutions so spatial dimensions match 1x1 outputs.
+- **Concatenation**: Join along the channel axis (axis=-1 or 1 depending on format, here we assume (H, W, C)).
