Transformer Inference Without Embeddings for Randomized Data
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Transformer-based algorithms struggle with inference accuracy for non-NLP datasets, particularly those with high randomness and variance, due to issues with data normalization, embedding, and convergence in Attention mechanisms, leading to suboptimal performance compared to CNN and GAN models.
Innovation Solution
Normalize input data to a small range [0, 1], integrate Time2Vec components, and modify the Attention mechanism to include multi-head operations and cross-attention, bypassing word embeddings, to enhance convergence and accuracy for time series and classification tasks.

Engineering Contradiction Analysis
1Adaptability or versatility
If Transformer algorithms are applied to non-NLP datasets with high randomness and variance, then the model can handle diverse data types, but inference accuracy deteriorates due to normalization and convergence issues
Solution Approach 1:
The patent applies parameter changes by normalizing input data to a specific range [0, 1] using MinMaxScaler, transforming the statistical properties of the input data to improve convergence and inference accuracy for non-NLP datasets with high randomness and variance
Solution Approach 2:
The patent implements preliminary action through data preprocessing steps including normalization and the use of pre-computed positional encodings before feeding data to the Transformer model, which prepares the data in advance to ensure better convergence and accuracy
2Device complexity
If standard embedding layers are used for non-NLP data, then the model architecture remains simple, but convergence and accuracy deteriorate compared to specialized preprocessing
Solution Approach 1:
The patent extracts and removes the standard embedding layer from the Transformer architecture when processing non-NLP data, replacing it with direct normalized numerical inputs and specialized positional encodings, thereby eliminating a source of convergence issues while maintaining architectural simplicity
Solution Approach 2:
The patent inverts the conventional approach by skipping the embedding layer entirely and directly inputting normalized numerical data with positional encodings, reversing the typical NLP pipeline to better suit non-NLP datasets
3Device complexity
If Attention mechanisms are used without modification for non-NLP data, then the model maintains original architecture, but inference performance deteriorates due to lack of specialized mechanisms
Solution Approach 1:
The patent applies dynamics by implementing multi-head attention mechanisms that can dynamically adapt to different patterns in the data, allowing the model to flexibly focus on different aspects of the input sequence relevant to time series and classification tasks

AI summary
The patent described herein refers to an artificial intelligence Transformer algorithm, used with processing mechanisms in the data input blocks that allow inference probabilities near 1. The Transformer algorithm belongs to a class of trainable Artificial Intelligence algorithms with autoencoder functions and attention mechanisms for several classes of inference problems. Certain datasets that appear to have a high degree of randomness can be manipulated to make predictions or classification with near certainty. In many cases, classification can be performed with 100% accuracy, a singular inference process. These datasets cover many practical problems and theoretical cases.
