The blocks are labeled "Depthwise Conv2D", "Batch Normalization", and "Activation". The module is labeled "Module 1" below the outline. The outline has a light yellow background. * **Module 2:** Contains six rectangular blocks connected by right-pointing arrows, arranged horizontally. The blocks are labeled "Depthwise Conv2D", "Batch Normalization", "Activation", "Zero Padding", "Depthwise Conv2D", "Batch Normalization", and "Activation". The module is labeled "Module 2" below the outline. The outline has a light gray background. * **Module 3:** Contains four rectangular blocks connected by right-pointing arrows, arranged horizontally. The blocks are labeled "Global Average Pooling", "Rescaling", "Conv2D", and "Conv2D". The module is labeled "Module 3" below the outline. The outline has a light pink background. * **Blocks:** Each block is a colored rectangle with text labels inside. Colors used are red ("Depthwise Conv2D", "Conv2D"), blue ("Batch Normalization"), purple ("Activation"), green ("Zero Padding"), orange ("Global Average Pooling"), and yellow ("Rescaling"). * **Arrows:** Black arrows connect the blocks, indicating the direction of flow from left to right within each module. * **Labels:** Text labels are present within the blocks (operation names) and below the module outlines (module names). **Textual Information:** * **Module 1:** * Depthwise Conv2D -> Batch Normalization -> Activation * Label: Module 1 * **Module 2:** * Depthwise Conv2D -> Batch Normalization -> Activation -> Zero Padding -> Depthwise Conv2D -> Batch Normalization -> Activation * Label: Module 2 * **Module 3:** * Global Average Pooling -> Rescaling -> Conv2D -> Conv2D * Label: Module 3 **Diagram Title:** MBConv **Chart Type:** Flowchart/Block Diagram **Main Elements:** * **Input:** Represented by stacked colored rectangles (orange, yellow, grey, purple, light purple). An arrow points from this stack to the first block. * **Blocks (Rectangles with text):** * "Conv 1x1, s1": Represents a 1x1 Convolution with stride 1. * "Depwise Conv k x k, s1/s2": Represents a Depthwise Convolution with kernel size k x k and stride s1 or s2. * "SE": Represents a Squeeze-and-Excitation block. * "Conv 1x1, s1": Represents a 1x1 Convolution with stride 1. * "Dropout": Represents a Dropout layer. * **Activation/Normalization Labels:** * "BN Swish": Appears after the first Conv block. * "BN Swish": Appears after the Depthwise Conv block. * "BN": Appears after the second Conv block. * **Operations (Symbols):** * "+": Represents an element-wise addition operation (residual connection). * **Output:** Represented by stacked colored rectangles (orange, yellow, grey, white, light red). An arrow points from the addition symbol to this stack. * **Arrows:** Indicate the direction of data flow through the network blocks. * **Skip Connection:** A horizontal arrow branches off from the output of the initial input representation, goes underneath the main path, and curves up to connect to the "+" symbol. **Flow Description:** The input data goes through a 1x1 Convolution followed by BN and Swish activation. Then it goes through a Depthwise Convolution (k x k, s1/s2 stride) followed by BN and Swish activation. Next is the SE block, followed by another 1x1 Convolution with stride 1, followed by BN. This is followed by a Dropout layer. The output of the Dropout layer is element-wise added to the original input data (via the skip connection), and this sum is the output of the MBConv block. **Diagram Description:** * Type: Flowchart or Neural Network Architecture Diagram. * Layout: Arranged horizontally as a sequence of blocks labeled Block 1 through Block 7, with data flow generally from left to right. There are also final layers after Block 7. * Elements: The diagram consists of various rectangular shapes with rounded corners, representing processing steps or modules (labeled Stem, conv, Module 1, Module 2, Module 3, Add, upsample, Final layers). These shapes have different background colors (pink, orange, blue, yellow, green). * Connections: Directed arrows indicate the flow of data between elements. Some arrows show sequential processing, while others represent skip connections bypassing one or more steps. **Textual Content and Structure:** * **Overall Structure:** Blocks are labeled Block 1, Block 2, Block 3, Block 4, Block 5, Block 6, Block 7. The diagram starts with 'Stem' and ends with 'Final layers'. * **Block 1:** * Contains: Stem, conv, Module 1, Module 3, Add. * Connections: * Stem -> conv * conv -> Module 1 * Module 1 -> Module 3 * Module 3 -> Add * Stem -> Add (skip connection) * **Block 2, Block 3, Block 4, Block 5, Block 6:** (These blocks share the same internal structure) * Each contains: Module 2, two instances of Module 3, two instances of Add. * Connections within this structure: * Input from previous block -> Module 2 * Module 2 -> Module 3 (first instance) * Module 3 (first instance) -> Add (first instance) * Input from previous block -> Add (first instance) (skip connection) * Add (first instance) -> Module 3 (second instance) * Module 3 (second instance) -> Add (second instance) * Add (first instance) -> Add (second instance) (skip connection) * Output of Add (second instance) -> next block * **Block 7:** * Contains: Module 2, Module 3, Add. * Connections within this structure: * Input from previous block -> Module 2 * Module 2 -> Module 3 * Module 3 -> Add * Input from previous block -> Add (skip connection) * **Final Layers:** * Contains: upsample, conv, Final layers. * Connections: * Output of Add in Block 7 -> upsample * upsample -> conv * conv -> Final layers * **Connections between Blocks:** * Output of Add in Block 1 connects to the input of Block 2 (connecting to Module 2 and the first Add). * Output of Add (second instance) in Block 2 connects to the input of Block 3 (connecting to Module 2 and the first Add). * Output of Add (second instance) in Block 3 connects to the input of Block 4 (connecting to Module 2 and the first Add). * Output of Add (second instance) in Block 4 connects to the input of Block 5 (connecting to Module 2 and the first Add). * Output of Add (second instance) in Block 5 connects to the input of Block 6 (connecting to Module 2 and the first Add). * Output of Add (second instance) in Block 6 connects to the input of Block 7 (connecting to Module 2 and the Add). * **Annotations:** * `x3` (red text) is located below the arrow connecting the output of Block 4 (second Add) to the input of Block 5. * `x3` (red text) is located below the arrow connecting the output of Block 5 (second Add) to the input of Block 6. * `x4` (red text) is located below the arrow connecting the output of Block 6 (second Add) to the input of Block 7. Chart/Diagram Description: * **Type:** Flowchart representing a neural network architecture. * **Main Elements:** * The diagram is organized into vertical columns labeled "Block 1" through "Block 7". * Components are represented by rounded rectangular boxes with text labels and distinct colors: * "Stem": Pink rounded rectangle, located on the left. * "Module 1": Orange rounded rectangle, located in Block 1. * "Module 2": Blue rounded rectangle, located at the top of Blocks 2 through 7. * "Module 3": Yellow rounded rectangle, located below "Module 1" in Block 1 and below "Module 2" in Blocks 2 through 7. Also located below the first "Add" in Blocks 2 through 7. * "Add": Green rounded rectangle, located below "Module 3" in Block 1 and below the first "Module 3" in Blocks 2 through 7. Also located at the bottom of Blocks 2 through 7. * "Final layers": Pink rounded rectangle, located on the right. * Connections are represented by black arrows indicating the direction of flow. * **Flow:** * An arrow goes from "Stem" to "Module 1". * An arrow goes from "Stem" to the first "Add" in Block 1 (a skip connection). * An arrow goes from "Module 1" to the first "Module 3" in Block 1. * An arrow goes from the first "Module 3" in Block 1 to the first "Add" in Block 1. * An arrow goes from the first "Add" in Block 1 to the "Module 2" in Block 2. * In Blocks 2 through 7, there is a main path: Input -> "Module 2" -> "Module 3" -> "Add". * In Blocks 2 through 7, there is also a skip connection: Input -> "Add". * The input to Block i (for i from 2 to 7) is the output of the "Add" in Block i-1. * An arrow goes from the "Add" in Block 7 to "Final layers". * **Labels and Annotations:** * Block labels: "Block 1", "Block 2", "Block 3", "Block 4", "Block 5", "Block 6", "Block 7" are placed above the respective columns. * Multiplier labels: Red text "x3" is placed below the bottom "Add" in Block 4. Red text "x3" is placed below the bottom "Add" in Block 6. Red text "x4" is placed below the bottom "Add" in Block 7. * Note that Blocks 2, 3, and 4 have the structure Module 2 -> Module 3 -> Add -> Module 3 -> Add (with skip connections). There appears to be a repetition of Module 3 and Add within Blocks 2-7 based on the diagram's vertical layout, contrary to the simpler description above. Let's re-describe the blocks based on the actual connections drawn: * Block 1: Stem -> Module 1 -> Module 3 -> Add (skip from Stem to Add). * Block 2: Input -> Module 2 -> Module 3 -> Add (skip from input to Add). The output of this Add then goes to *another* Module 3 -> Add (with a skip from the first Add's output to the second Add). * Blocks 3, 4, 5, 6, and 7 have the same internal structure as Block 2: Input -> Module 2 -> Module 3 -> Add (skip from input) -> Module 3 -> Add (skip from the first Add's output). * Let's correct the previous description of Module 3 and Add repetition. The diagram shows: * Block 1: Stem -> Module 1 -> Module 3 -> Add (skip from Stem). Output goes to Block 2. * Block 2: Input -> Module 2 -> Module 3 -> Add (skip from Input). Output goes to Block 3 AND to the next Module 3 in Block 2. * Let's re-examine the arrows closely. The structure within Blocks 2-7 is: Input at the top (Module 2) -> Module 2 -> Module 3 -> Add. There is a skip connection from the input directly to this Add. This Add's output then goes to *another* Module 3, whose output goes to *another* Add. There is *another* skip connection from the output of the *first* Add to the *second* Add. * So, within Blocks 2-7, the structure is: Input -> [Module 2 -> Module 3 -> Add (skip from Input)] -> [Module 3 -> Add (skip from first Add)]. * The output of Block i is the output of the second "Add" in Block i. * Block 1 output (first Add) goes to Block 2 input (Module 2). * Block 2 output (second Add) goes to Block 3 input (Module 2). * Block 3 output (second Add) goes to Block 4 input (Module 2). * Block 4 output (second Add) has "x3" below it and goes to Block 5 input (Module 2). This confirms Blocks 2, 3, 4 are similar. * Block 5 output (second Add) goes to Block 6 input (Module 2). * Block 6 output (second Add) has "x3" below it and goes to Block 7 input (Module 2). This suggests Blocks 5 and 6 are similar, part of a group of 3. * Block 7 output (second Add) has "x4" below it and goes to "Final layers". This suggests Block 7 is part of a group of 4. * **Corrected Flow Description:** * Input enters "Stem". * Output of "Stem" feeds into "Module 1". * Output of "Module 1" feeds into "Module 3". * Output of "Module 3" feeds into the "Add" in Block 1. * A skip connection goes directly from "Stem" to the "Add" in Block 1. * The output of the "Add" in Block 1 is the input for Block 2. * Within Blocks 2, 3, 4, 5, 6, and 7, the structure is: * Input goes to "Module 2". * Output of "Module 2" goes to the first "Module 3". * Output of the first "Module 3" goes to the first "Add". * A skip connection goes from the input to the first "Add". * The output of the first "Add" goes to the second "Module 3". * Output of the second "Module 3" goes to the second "Add". * A skip connection goes from the output of the first "Add" to the second "Add". * The output of Block i (for i=2..7) is the output of the second "Add" in Block i. * The output of the second "Add" in Block 4 is labeled with "x3". * The output of the second "Add" in Block 6 is labeled with "x3". * The output of the second "Add" in Block 7 is labeled with "x4". * The output of the second "Add" in Block 7 goes to "Final layers". The diagram represents a structure with an initial Stem, followed by multiple stacked blocks (Block 1 to Block 7). Block 1 has a different internal structure (Module 1 -> Module 3 -> Add) compared to Blocks 2-7. Blocks 2-7 have a repeated internal structure involving Module 2, two Module 3s, and two Add operations with skip connections. The "x3" and "x4" labels likely indicate repetitions of similar block types in a larger architecture being represented by these diagram sections.
