Real Time Predictions of VGF-GaAs Growth Dynamics by LSTM Neural Networks

نویسندگان

چکیده

The aim of this study was to assess the aptitude recurrent Long Short-Term Memory (LSTM) neural networks for fast and accurate predictions process dynamics in vertical-gradient-freeze growth gallium arsenide crystals (VGF-GaAs) using datasets generated by numerical transient simulations. Real time temperatures solid–liquid interface position GaAs are crucial control applications visualization, i.e., generation digital twins. In reported study, an LSTM network trained on 1950 with 2 external inputs 6 outputs. Based performance criteria training results, LSTMs showed very VGF-GaAs median root-mean-square-error (RMSE) values × 10?3. This deep learning method achieved a superior predictive accuracy timeliness compared more traditional Nonlinear AutoRegressive eXogenous (NARX) networks.

Morphological Segmentation with Window LSTM Neural Networks

Morphological segmentation, which aims to break words into meaning-bearing morphemes, is an important task in natural language processing. Most previous work relies heavily on linguistic preprocessing. In this paper, we instead propose novel neural network architectures that learn the structure of input sequences directly from raw input words and are subsequently able to predict morphological b...

LSTM Neural Networks for Language Modeling

Neural networks have become increasingly popular for the task of language modeling. Whereas feed-forward networks only exploit a fixed context length to predict the next word of a sequence, conceptually, standard recurrent neural networks can take into account all of the predecessor words. On the other hand, it is well known that recurrent networks are difficult to train and therefore are unlik...

Real-time learning capability of neural networks

In some practical applications of neural networks, fast response to external events within an extremely short time is highly demanded and expected. However, the extensively used gradient-descent-based learning algorithms obviously cannot satisfy the real-time learning needs in many applications, especially for large-scale applications and/or when higher generalization performance is required. B...
