This means that all historical data sets can be used for RUL prediction (initial prediction data) (Chang: pg. 5670, section II.B; etc.); where the test condition data is test sample design data]; obtaining a determined result according to an error value of the initial prediction data with respect to test sample test data, comprising: [Specifically, a similarity weight, defined as the degree of affinity between two different LED’s degradation trends, is derived from the difference between a test unit’s degradation trend and a training unit’s degradation trend. Likewise, the RVM is used to represent a unit’s degradation behavior (Chang: pg. 5667, abstract; etc.), which includes training the RVM using training samples for test condition (design) and test result (test) data (Chang: pg. 5669, fig. 1; pg. 5671, section III; etc.); This prediction process can utilize any training data set that was conducted for all devices. This means that all historical data sets can be used for RUL prediction (Chang: pg. 5670, section II.B; etc.); where the model can be trained recursively (i.e., inputting the output of the model, to the model) (Chang: pg. 5668, section I; pg. 5669, section II; etc.), and includes adjusting model parameters by minimizing a predetermined error (loss) function (Chang: pgs. 5669-5670, section II.A; pgs. 5672-5673, section IV.A; pg. 5675, table III; etc.)]; wherein the test sample test data is test data of the test sample display device [Specifically, a similarity weight, defined as the degree of affinity between two different LED’s degradation trends, is derived from the difference between a test unit’s degradation trend and a training unit’s degradation trend. Likewise, the RVM is used to represent a unit’s degradation behavior (Chang: pg. 5667, abstract; etc.), which includes training the RVM using training samples for test condition (design) and test result (test) data (Chang: pg. 5669, fig. 1; pg. 5671, section III; etc.); This prediction process can utilize any training data set that was conducted for all devices. This means that all historical data sets can be used for RUL prediction (initial prediction data) (Chang: pg. 5670, section II.B; etc.); where the test result data is the test data of the test sample device (the LED(s))]; obtaining a prediction accuracy rate of the initial prediction model according to at least one determined result [an error percentage is calculated for the predictions of the model (Chang: pg. 5674, table II; etc.); which is a prediction accuracy rate]; and determining the initial prediction data as a performance prediction model [the RVM is used to make a RUL (performance) prediction of the LED (target display device) according to the similarity of the device and test conditions to the test datasets (Chang: pg. 5669, fig. 1; etc.); and an error percentage is calculated for the predictions of the model (Chang: pg. 5674, table II; etc.); which is a prediction accuracy rate].
While Chang/Dillman teaches a specified training phase for the machine learning model, including calculating an error value of the prediction data (see above), it has not been relied upon for teaching when the error value of the initial prediction data with respect to the test sample test data is less than or equal to a first pre-set threshold, determining that the initial prediction model predicts accurately, otherwise determining that the initial prediction model predicts incorrectly; and determining the initial prediction data as a performance prediction model when the prediction accuracy rate is greater than or equal to a second pre-set threshold value.
However, the examiner takes official notice that utilizing pre-determined accuracy/error metric thresholds to determine when a model has completed training or can be used for inference is old and well-known within the art. Therefore, it would have been obvious to one of ordinary skill in the art, before the effective filing date of the claimed invention to, when the error value of the initial prediction data with respect to the test sample test data is less than or equal to a first pre-set threshold, determining that the initial prediction model predicts accurately, otherwise determining that the initial prediction model predicts incorrectly; and determining the initial prediction data as a performance prediction model when the prediction accuracy rate is greater than or equal to a second pre-set threshold value, in the system taught by Chang, utilizing the error rate calculations of Chang, to achieve the predictable result of ensuring that the model is sufficiently accurate before utilizing its predictions, and provide a desired tradeoff between resource usage/training time and model accuracy.
As per claim 11, Chang/Dillman teaches, after the step of determining that the initial prediction model predicts accurately, further comprising: regarding the test sample design data as the training sample design data, regarding the test sample test data as the training sample test data, and updating the training sample set; and training the performance prediction model according to an updated training sample set [This method recursively updates the health degradation data with the online prognostics result in real time. (Chang: pg. 5669, section II and fig. 1; etc.) which can also include recursively updating the model with online updating (Chang: pg. 5668; section I; etc.)].
Response to Arguments
The objections to the drawings and to the title have been withdrawn due to the amendments filed.
The rejections of claims 10, 11, 16, and 18 under 35 U.S.C. 112(b) have been withdrawn due to the amendments filed.
Applicant's arguments filed 30 March 2026 have been fully considered but they are not persuasive.
Applicant argues that the cited art does not teach wherein the model to be trained is a fully-connected neural network or a transformer model, and there is at least one skip connection between different network levels of a fully-connected layer of the model to be trained; wherein, the at least one skip connection is used for inputting output values of network levels separated by at least two layers into a pre-set network layer after being fused; the pre-set network layer is a deep network separated from a fused network layer by at least three layers
However, as described above, Dillman teaches an ensemble of learning models can be used to improve prediction performance, including fully-connected neural networks and SVM models, etc., (paras. 0067, 0087, etc.), for the vector machine model of Chang, above, and where the neural network can include multiple skip connections between different fully connected layers and fusion blocks of the neural network(s), where different channels may be fused (Dillman: paras. 0081, 0090, etc.) which can skip more than 3 layers (see, e.g., Dillman: figs. 5, 11, etc., which show skipping more than 3 layers and connecting to the fusion network layers). Here the skip connections are skipping at least 3 layers in the fully connected network layers, providing outputs to the fusion network layers.
Examiner also notes that the applicant has not traversed examiner’s assertion of official notice. Therefore, the common knowledge or well-known in the art statement is taken to be admitted prior art. See MPEP § 2144.03(C).
