Monitoring of pH is crucial for several chemical and biochemical processes. ISFET (Ion-Sensitive Field-Effect Transistors)-based sensors are promising candidates monitoring applications. However, devices prone to temporal temperature drifts, which severely affects the precision measurements. In this work, we collect experimental data drifts in an sensor formulate accurate SPICE macro model, incorporating both non-idealities. The developed model utilized generating training state-of-the-art...

Fine-tuning is widely used as the default algorithm for transfer learning from pre-trained models. Parameter inefficiency can however arise when, during learning, all parameters of a large model need to be updated individual downstream tasks. As number grows, fine-tuning prone overfitting and catastrophic forgetting. In addition, full become prohibitively expensive when many To mitigate this issue, parameter-efficient algorithms, such adapters prefix tuning, have been proposed way introduce...

Larger language models (LLMs) have taken the world by storm with their massive multi-tasking capabilities simply optimizing over a next-word prediction objective. With emergence of properties and encoded knowledge, risk LLMs producing harmful outputs increases, making them unfit for scalable deployment public. In this work, we propose new safety evaluation benchmark RED-EVAL that carries out red-teaming. We show even widely deployed are susceptible to Chain Utterances-based (CoU) prompting,...

Stock price prediction is one of the most complex machine learning problems. It depends on a large number factors which contribute to changes in supply and demand. In this paper, we propose stock analysis using based support vector machines (SVM), linear regression reinforcement learning. SVM are favored applications where text mining used for market prediction. SVMs can be both linearly non-linearly separable data sets. when separable, construct hyperplane feature space distinguish training...

Semi-parametric Nearest Neighbor Language Models (kNN-LMs) have produced impressive gains over purely parametric LMs, by leveraging large-scale neighborhood retrieval external memory datastores. However, there has been little investigation into adapting such models for new domains. This work attempts to fill that gap and suggests the following approaches kNN-LMs — 1) underlying LM (using Adapters), 2) expanding an additional adaptation datastore, 3) weights (scores) of retrieved neighbors...

Neural speech synthesis, or text-to-speech (TTS), aims to transform a signal from the text domain domain. While developing TTS architectures that train and test on same set of speakers has seen significant improvements, out-of-domain speaker performance still faces enormous limitations. Domain adaptation new can be achieved by fine-tuning whole model for each domain, thus making it parameter-inefficient. This problem solved Adapters provide parameter-efficient alternative adaptation....

Prompt Tuning has been largely successful as a parameter-efficient method of conditioning large-scale pre-trained language models to perform downstream tasks. Thus far, soft prompt tuning learns fixed set task-specific continuous vectors, i.e., tokens that remain static across the task samples. A prompt, however, may not generalize well diverse kinds inputs comprises. In order address this, we propose Vector-quantized Input-contextualized Prompts (VIP) an extension framework. VIP...
