## Diagram: Cognitive Functions and Computational Model ### Overview The image illustrates the process of building a computational model based on cognitive functions of the human brain. It shows the flow from brain activation data to a language computational model, highlighting key aspects like mechanisms of representation, neuron workings, and applications like dialogue systems and machine translation. ### Components/Axes * **Header:** Contains two main titles: "Cognitive functions of human brain" and "Build a computational model". * **Left Side:** * A line drawing of a human head in profile. * A brain scan image with highlighted regions in red, green, and yellow. * A graph showing brain activation data with three lines (blue, green, and red). * Label: "Brain activation data" * **Middle Section:** * Three bullet points: * Mechanisms of representation, learning, memory, et al. * Working mechanisms of neurons * Brain activation and behavior data * Two blue arrows indicating the flow of information. * **Right Side:** * A brain-shaped diagram composed of interconnected nodes and lines. * Four bullet points: * Dialogue systems * Machine translation * Emotion analysis * Speech recognition * Label: "Language computational model" ### Detailed Analysis or ### Content Details * **Brain Scan:** The brain scan shows highlighted regions. The approximate locations are: * Red: Frontal lobe, both hemispheres * Green: Parietal lobe, left hemisphere * Yellow: Temporal lobe, right hemisphere * **Brain Activation Data:** The graph shows three lines, each with varying amplitudes and frequencies, suggesting different activation patterns. * Blue line: Shows a relatively stable pattern with small fluctuations. * Green line: Exhibits more frequent and larger amplitude changes. * Red line: Shows a pattern with both high and low amplitude peaks. * **Computational Model:** The brain-shaped diagram on the right represents a neural network or similar computational model. The nodes are interconnected, symbolizing the complex relationships within the model. ### Key Observations * The diagram illustrates a progression from raw brain activation data to a computational model capable of language-related tasks. * The bullet points in the middle section highlight the key areas of study and modeling. * The applications listed on the right side (dialogue systems, machine translation, etc.) represent the potential outcomes of this research. ### Interpretation The diagram presents a high-level overview of how cognitive functions of the human brain can be translated into computational models, specifically for language-related tasks. It suggests that understanding the mechanisms of representation, neuron workings, and brain activation patterns is crucial for developing these models. The diagram implies a research direction where brain data informs the creation of AI systems capable of complex language processing. The connection between brain activation data and specific cognitive functions is a key element, suggesting that different brain regions and activation patterns are linked to different aspects of language processing.
