Deep Learning: A Comprehensive Overview on Techniques, Taxonomy, Applications and Research Directions SpringerLink

Transformer neural networks (TNN), also known as transformers, are powerful neural networks that have been widely used in natural language processing [36]. Transformers were developed to solve the problems of sequence-to-sequence transduction and neural machine translation. They consist of encoder–decoder layers and are trained through pre-training and fine-tuning. In doing so, the model can thereby assign higher weights to relevant words or tokens and pay attention to them more effectively during processing. While transformers have been highly successful in natural language processing, they also have limitations. A typical neural network is mainly composed of many simple, connected processing elements or processors called neurons, each of which generates a series of real-valued activations for the target outcome.

Areas of application of neural networks

Biased data sets are an ongoing challenge in training systems that find answers on their own through pattern recognition in data. If the data feeding the algorithm isn’t neutral — and almost no data is — the machine propagates bias. Neural networks are widely used in a variety of applications, including image recognition, predictive modeling and natural language processing (NLP). Examples of significant commercial applications since 2000 include handwriting recognition for check processing, speech-to-text transcription, oil exploration data analysis, weather prediction and facial recognition. To summarize, deep learning is a fairly open topic to which academics can contribute by developing new methods or improving existing methods to handle the above-mentioned concerns and tackle real-world problems in a variety of application areas.


Next, the merged images were superimposed and merged using the manual alignment option. The optimization algorithm was an iterative closest point (ICP) algorithm without nonlinear deformation, which is often applied to rigid 3D objects63. First, the automatic alignment option of that IDEA was used to correct small disagreements between its 16 images, and integrated them. The merged image was obtained for the number of times it was recorded from the same object. Prior to slice preparation, mice are thoroughly anesthetized (1%-1.5% isoflurane), cervical vertebrae was dislocated, and brains are removed.

Areas of application of neural networks

At each point in time the agent performs an action and the environment generates an observation and an instantaneous cost, according to some (usually unknown) rules. At any juncture, the agent decides whether to explore new actions to uncover their costs or to use of neural networks exploit prior learning to proceed more quickly. Machine learning is commonly separated into three main learning paradigms, supervised learning,[112] unsupervised learning[113] and reinforcement learning.[114] Each corresponds to a particular learning task.

Signatures are one of the most powerful ways to authorize and authenticate anyone in legal transactions. The following are the areas where the Artificial Neural Network is being utilized. ANN has an interdisciplinary approach in its applications and development. Here the value of the outcome is unknown, but the network gives feedback on whether the result is correct or wrong.

Our review contains general information about AI, which was broken down into individual techniques that are used in it to familiarise readers with basic information on the subject. Other articles cover our selected topics in detail, often going into technical details or focusing on only one selected field of medicine. Only one of the papers we identified treated a similar topic, but its aim was different from ours. The review of Ahmad et al. presented a variety of approaches to the practical applications of AI in clinical practice that were extended with a theoretical elaboration that was broader than ours [90]. They provided a large number of examples, which were grouped according to the target specialty. We also provided numerous examples of different models’ usage but lacked the division to certain specialties.

The LSTM network has been applied to speech recognition65, language modeling66, and many other tasks. For example, the Transformer model52, which uses the self-attention mechanism to deal with correlation in sequential data, can potentially learn even longer temporal correlations than the LSTM model. This study collectively analyzed populations of neurons existing in the square region used for electrical measurements.

Another major healthcare field that makes extensive use of CNNs is drug discovery. It is also one of the most inventive uses of convolutional neural networks in general. These contain multiple neural networks working separately from one another. The networks don’t communicate or interfere with each other’s activities during the computation process. Consequently, complex or big computational processes can be performed more efficiently.

  • In case the actual outcome is different from the target outcome, the difference or error is found out.
  • Commonly, Artificial Neural Network has an input layer, an output layer as well as hidden layers.
  • A Both training data and prediction, generation, data are prepared from the same region in this evaluation.
