Abstract
Description
Technical Field
[0001] The embodiments of the present application relate to the field of medical diagnosis technology, and in particular to an automatic evaluation method and system based on the Glasgow Coma Scale. Background Art
[0002] With the rapid development of medical information technology and artificial intelligence technology, the field of medical diagnosis and evaluation is undergoing profound changes. In modern clinical environments, accurate assessment of patients' coma status is crucial, especially in high-risk environments such as intensive care units and emergency departments. Traditional assessment methods rely on the subjective judgment of doctors, which has large individual differences and time delays. Therefore, there is an urgent need for a method that can automatically and finely assess the patient's coma level to improve the accuracy and efficiency of diagnosis.
[0003] At present, common coma assessment methods mainly include the traditional Glasgow Coma Scale and some rule-based semi-automated assessment tools. Although these methods can reflect the patient's coma state to a certain extent, they still rely on the doctor's experience and subjective judgment, and fail to make full use of multimodal data (such as behavioral response, verbal response, and eye opening response), resulting in incomplete information and affecting the accuracy of the assessment. In addition, most of the existing methods are based on fixed rules and lack a dynamic adjustment mechanism, making it difficult to adapt to the complex and changing clinical environment, especially in emergency situations, which may delay the best treatment time.
[0004] Although existing coma assessment methods are widely used in clinical practice, they still have significant defects, especially the low degree of automation and refinement of the assessment, which makes it difficult to capture subtle changes in the patient's condition, resulting in limited assessment accuracy. The manual assessment process is time-consuming and inefficient, and it is difficult to generate personalized medical advice based on the specific situation of each patient, which affects the optimization of treatment effects.

Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of this application.
[0059] Figure 1 A flowchart of an automatic assessment method based on the Glasgow Coma Scale is provided for an embodiment of the present application, such as Figure 1 As shown, the method includes:
[0060] 101. Collect patient behavioral response data, verbal response data, and eye-opening response data to generate an initial evaluation data set;
[0061] In this step, the behavioral response data includes information such as the patient's motor response and limb activity, which is used to evaluate the patient's motor ability and reaction speed to external stimuli. For example, the patient's limb movement frequency, strength, and reaction time are all part of the behavioral response data.
[0062] Verbal response data covers information such as the patient's voice, intonation, vocabulary selection, etc., reflecting their cognitive and language functions. By analyzing the verbal response data, we can understand the patient's level of consciousness, clarity of thinking, and emotional state.
[0063] The eye opening response data records the patient's eye activities under specific stimulation, such as eye opening frequency, pupil changes, etc., which is used to assess the level of consciousness and can help judge the patient's alertness and cognitive ability to the external environment.
[0064] The initial evaluation dataset is a data set formed by integrating the data of the above three modalities after preprocessing. It provides a basis for subsequent advanced feature extraction and sentiment analysis, and ensures the consistency and integrity of multimodal data.
[0065] In an embodiment of the present application, assuming that in an intensive care unit environment, first, the patient's behavioral response data is monitored in real time through smart sensors and wearable devices to ensure the continuity and integrity of the data; secondly, the patient's verbal response data is collected and processed using speech recognition technology and natural language processing tools to remove background noise and irrelevant information; thirdly, the patient's eye opening response data is captured in combination with a video surveillance system, and time synchronization is performed to ensure the consistency of data in different modalities; finally, all collected data is standardized and normalized to generate a high-quality initial evaluation data set to prepare for subsequent analysis.
[0066] 102. Based on the initial evaluation data set, use the gated recurrent unit algorithm to perform advanced sequence feature extraction processing on the behavioral response data, use deep sentiment analysis technology to perform deep sentiment tendency analysis on the verbal response data, and generate a behavioral verbal response score;
[0067] In this step, the gated recurrent unit is an improved recurrent neural network that can effectively capture dependencies in long time series and control the flow of information through a gating mechanism, thereby enhancing the model's ability to understand time series data. It is particularly suitable for complex dynamic patterns in behavioral response data.
[0068] Advanced sequence feature extraction is to extract representative feature vectors from behavioral response data. These features can reflect the patient's behavioral patterns and their changing trends. Through multi-level time series feature extraction, long-term dependencies can be captured and the accuracy of the assessment can be improved.
[0069] Deep sentiment analysis technology uses deep learning models to encode verbal response data, obtain context-related sentiment word vector representations, and identify key emotional information such as joy, anger, fear, etc. through sentiment classifiers to assess the patient's psychological state.
[0070] The behavioral and verbal response score comprehensively reflects the patient's behavioral and emotional expressions. By weighted fusion of the behavioral response feature vector and the emotional word vector, a comprehensive score is generated. This score not only takes into account the patient's behavioral pattern, but also includes the emotional component, thereby more comprehensively reflecting the patient's status.
[0071] In an embodiment of the present application, assuming that in an emergency department scenario, a gated recurrent unit algorithm is first applied to perform multi-level time series feature extraction on the behavioral response data to capture long-term dependencies and generate a behavioral response feature vector; secondly, a deep learning model is used to encode the verbal response data to obtain context-related sentiment word vector representations, and the behavioral response feature vectors are combined with the behavioral response feature vectors to input into a sentiment classifier to identify key sentiment information; thirdly, the behavioral response feature vectors and sentiment word vectors are fused through preset weighting rules to generate a behavioral speech feature vector; finally, the behavioral speech response score is calculated based on this feature vector, providing an important basis for subsequent comprehensive evaluation.
[0072] Optionally, in step 102, based on the initial evaluation data set, a gated recurrent unit algorithm is used to perform high-level sequence feature extraction processing on the behavior response data, and a deep sentiment analysis technology is used to perform a deep-level sentiment tendency analysis on the speech response data to generate a behavior speech response score, including: based on the initial evaluation data set, preprocessing the behavior response data to ensure that the data format is consistent and remove noise, and generate preprocessed behavior response data; based on the preprocessed behavior response data, a gated recurrent unit algorithm is used to control the flow of information through a gating mechanism, capture long-term dependencies in the time series, and generate a behavior response feature vector through multi-layer gated recurrent unit processing and fully connected layer mapping; based on the behavior response feature vector, the deep sentiment analysis technology is used to encode the speech response data, and a context-related word vector representation is obtained, which is combined with the behavior response feature vector and input into a sentiment classifier to identify key sentiment information and generate a behavior speech feature vector; based on the behavior speech feature vector, weighted fusion is performed through preset weighting rules to generate a behavior speech response score.
[0073] In this step, preprocessing the behavioral response data includes standardizing and denoising the behavioral response data in the initial evaluation data set to ensure consistent data format and remove noise. This process improves the accuracy of subsequent feature extraction and reduces interference from irrelevant information.
[0074] Behavioral response feature vectors are generated by applying multi-layer gated recurrent unit processing and fully connected layer mapping to the preprocessed behavioral response data. These feature vectors capture the time series characteristics of the patient's behavioral pattern and reflect their reaction speed and motor ability to external stimuli.
[0075] Behavior-speech feature vector: The behavior-speech feature vector is a comprehensive feature vector generated by combining the behavior response feature vector with the emotion word vector and inputting it into the emotion classifier to identify key emotion information. This vector not only includes the behavior pattern, but also covers the emotion component, reflecting the patient's condition more comprehensively.
[0076] First, the behavioral response data is preprocessed to ensure the consistency of the data format and remove noise to generate preprocessed behavioral response data; then, based on the preprocessed behavioral response data, the gated recurrent unit algorithm is used to capture the long-term dependencies in the time series, and the behavioral response feature vector is generated through multi-layer gated recurrent unit processing and fully connected layer mapping; then, the speech response data is encoded using deep sentiment analysis technology to obtain context-related word vector representations, and combined with the behavioral response feature vector, it is input into the sentiment classifier to identify key sentiment information and generate a behavioral speech feature vector; finally, based on the behavioral speech feature vector, weighted fusion is performed through preset weighting rules to generate a behavioral speech response score. This process not only improves the accuracy of feature extraction, but also enhances the depth of sentiment analysis, providing richer information support for subsequent evaluation.
[0077] Optionally, based on the pre-processed behavior response data, a gated recurrent unit algorithm is used to control the flow of information through a gating mechanism, capture medium- and long-term dependencies in the time series, and generate a behavior response feature vector through multi-layer gated recurrent unit processing and fully connected layer mapping, including: based on the pre-processed behavior response data, input into a gated recurrent unit network, perform initialization processing, and generate an initial state; based on the initial state, a gated recurrent unit algorithm is used to control the flow of information through an update gate and a reset gate, capture medium- and long-term dependencies in the time series, and generate an intermediate state representation; based on the intermediate state representation, high-level features are further extracted through multi-layer gated recurrent units, internal states are updated, and the current moment behavior feature representation is output through an output gate to generate a deep feature representation; based on the deep feature representation, mapping is performed through multiple fully connected layers to convert high-dimensional feature vectors into fixed-length feature vectors to generate a behavior response feature vector.
[0078] The method is based on the behavior response feature vector, uses deep sentiment analysis technology to encode the speech response data, obtains context-related word vector representation, combines the behavior response feature vector with the input into a sentiment classifier, identifies key sentiment information, and generates a behavior speech feature vector, including: based on the behavior response feature vector, performs adaptation processing through feature mapping to adapt the speech response data and generate an adapted behavior response feature vector; based on the adapted behavior response feature vector, uses deep sentiment analysis technology to encode the speech response data, introduces the adapted behavior response feature vector, and generates a context-related word vector representation; based on the context-related word vector representation, combines the adapted behavior response feature vector, performs weighted fusion processing to combine multiple effective information and generate a combined feature vector; based on the combined feature vector, inputs into a dedicated sentiment classifier, performs deep feature extraction and pattern recognition through a multi-layer neural network, identifies key sentiment information, and generates a behavior speech feature vector.
[0079] In this step, the gated recurrent unit network initialization refers to inputting the preprocessed behavioral response data into the gated recurrent unit network to generate an initial state.
[0080] The update gate and reset gate are the core mechanisms of the gated recurrent unit algorithm, which are used to control the flow of information. The update gate determines which information needs to be updated, while the reset gate determines whether to ignore the state of the previous moment.
[0081] Intermediate state representation refers to the temporary state vectors generated during the operation of the gated recurrent unit algorithm. These vectors reflect the behavioral characteristics of the current moment and serve as the basis for further feature extraction.
[0082] Deep feature representation refers to further extracting high-level features through multi-layer gated recurrent units, updating the internal state, and outputting the behavioral feature representation of the current moment through the output gate. These features capture deeper time series patterns and enhance the expressiveness of the model.
[0083] Fully connected layer mapping refers to converting high-dimensional feature vectors into fixed-length feature vectors through multiple fully connected layers. This process simplifies the feature representation and makes it more suitable for subsequent classification and regression tasks.
[0084] Adapting the behavioral response feature vector refers to adapting the speech response data by performing feature mapping processing on the behavioral response feature vector. This adaptation process ensures the compatibility between different modal data and provides a unified basis for subsequent sentiment analysis.
[0085] Context-related word vector representation refers to the use of deep sentiment analysis technology to encode and process speech response data, combined with word vectors generated by adapting behavioral response feature vectors. These word vectors not only contain the semantic information of the speech content, but also incorporate behavioral characteristics, enhancing the accuracy of sentiment analysis.
[0086] A combined feature vector refers to a comprehensive feature vector generated by weighted fusion processing, combining context-related word vector representation and adaptive behavior response feature vector. This combination method makes full use of a variety of effective information and provides richer input for the sentiment classifier.
[0087] A dedicated emotion classifier refers to a multi-layer neural network designed specifically for identifying key emotional information. Through deep feature extraction and pattern recognition, this classifier can accurately identify the patient's emotional tendencies and generate behavioral speech feature vectors.
[0088] In the embodiment of the present application, the pre-processed behavior response data is first input into the gated recurrent unit network for initialization processing, and the gated recurrent unit algorithm is used to control the flow of information through the update gate and the reset gate to capture the long-term dependency in the time series and generate the intermediate state representation; secondly, based on the intermediate state representation, high-level features are further extracted through multi-layer gated recurrent units, the internal state is updated, and the behavior feature representation at the current moment is output through the output gate, and the mapping is performed through multiple fully connected layers to convert the high-dimensional feature vector to a fixed-length feature vector to generate a behavior response feature vector. Thirdly, adaptation processing is performed through feature mapping to adapt the speech reaction data to generate an adapted behavior response feature vector, encoding processing is performed to generate a context-related word vector representation, and weighted fusion processing is performed to generate a combined feature vector; finally, it is input into a dedicated emotion classifier, and deep-level feature extraction and pattern recognition are performed through a multi-layer neural network to identify key emotional information and generate a behavior speech feature vector.
[0089] Assuming that in an environment of an Alzheimer's care center, the collected behavioral response data is first preprocessed to ensure that the data format is consistent and noise is removed, and high-quality preprocessed behavioral response data is generated and input into the gated recurrent unit network for initialization processing to generate an initial state; secondly, the gated recurrent unit algorithm is used to control the flow of information through update gates and reset gates, capture long-term dependencies in time series, generate intermediate state representations, further extract high-level features through multi-layer gated recurrent units, update internal states, and output the current moment behavioral feature representation through output gates, and map through multiple fully connected layers to convert high-dimensional feature vectors to fixed lengths. feature vector to generate a behavioral response feature vector; again, based on the behavioral response feature vector, adaptation processing is performed through feature mapping to adapt the verbal response data, encoding processing is performed, and the adapted behavioral response feature vector is introduced to generate a context-related word vector representation, and the context-related word vector representation and the adapted behavioral response feature vector are combined to perform weighted fusion processing to generate a combined feature vector; finally, it is input into a dedicated emotion classifier, and deep feature extraction and pattern recognition are performed through a multi-layer neural network to identify key emotional information and generate a behavioral speech feature vector, which provides doctors with a more comprehensive basis for patient status assessment and supports the formulation of personalized treatment plans.
[0090] The present application takes into account the problem that the prior art is not accurate enough in capturing the long-term dependencies of time series, so the embodiment of the invention proposes this optional solution, which enhances the ability to understand time series data by introducing the update gate and reset gate mechanism in the gated recurrent unit algorithm, so as to solve the technical problem that traditional methods are difficult to process long time interval information; in addition, the existing methods are relatively simple in expressing nonlinear characteristics, resulting in insufficient expressiveness and flexibility of the model; therefore, this solution introduces a variety of nonlinear activation functions and transformations, such as sine functions, exponential functions, etc., to capture potential time series dependencies and improve the expressiveness of the model.
[0091] Optionally, based on the initial state, a gated recurrent unit algorithm is used to control the flow of information by updating gates and resetting gates, capturing long-term dependencies in the time series, and generating an intermediate state representation, including:
[0092] Based on the initial state, concatenate the input data with the hidden state vector of the previous time step, and map them to a suitable feature space through linear transformation;
[0093] Apply nonlinear activation functions to introduce nonlinear characteristics, enhance the model's expressiveness, and introduce sine and exponential functions to further capture potential time series dependencies to generate update gate outputs;
[0094] The update gate output is calculated using the following formula:
[0095]
[0096] Among them, z t is the update gate output at time step t; W z is the weight matrix of the update gate; h t-1 is the hidden state vector of the previous time step; x t is the input vector of the current time step; b z is the bias term of the update gate; σ is the nonlinear activation function Sigmoid function; α is the coefficient for adjusting the exponential function; β is the coefficient for adjusting the amplitude of the sine function; γ is the coefficient for adjusting the frequency of the sine function;
[0097] Based on the update gate output, perform an element-by-element multiplication operation on the hidden state vector of the previous time step to control the flow of information, transform it through a specific weight matrix, and introduce a bias term to generate a reset gate output;
[0098] The reset gate output is calculated using the following formula:

[0101] Based on the reset gate output, element-by-element selective transmission is performed, and rich feature representation is introduced through high-order polynomial transformation and dynamic threshold adjustment.
