Data Streaming plays a major role due to data generated from infinite sources. Stream data is the continuous flow of data from heterogeneous sources. Stream data allows the system to process data in real time, responding much faster than other data processing methods. Unlike traditional batch processing, stream data processing utilizes less time to process the data and provide immediate response in real-time.
Deep learning models produce superior and accurate results in handling huge data streams generated from various sources with better prediction. Streaming data requires analysis of immediate insights extraction and fast decision-making, which is highly possible with deep learning models. In stream classification and data stream mining, an abrupt change in the distribution of data sets over time is considered concept drift.
Deep learning models detect the concept of drift and track the changes in data stream classification applications. Commonly used deep learning algorithms are the convolutional neural network, long short-term memory, general adversarial network, and active learning.
Online Learning: Static datasets are usually used for the offline training deep learning models. However, data stream processing deals with dynamic data that might be too big to store and retrain models.
Concept Drift: The term is used to describe the tendency for an underlying data distribution in data streams to shift over time. For deep learning models to stay accurate, they may need to recognize the mentioned changes and adjust accordingly.
Low Memory Footprint: Conventional deep learning model needs a large amount of memory frequently created to be memory-efficient in data stream processing, utilizing strategies like model compression and knowledge distillation.

Complex Pattern Recognition: Deep learning is smart at identifying relationships and patterns in data. Because of this, it works well with data streams that have complex and dynamic structures, enabling it to find important insights and identify anomalies that conventional approaches might overlook.
Adaptability to Concept Drift: Deep learning models can adjust concept drift, which is a shift in the data distribution. To remain relevant in environments with dynamic data streams, they can modify their parameters and update their knowledge regularly.
Feature Learning: By identifying and extracting relevant characteristics from data, deep learning models remove the need for human feature engineering. This is especially helpful in data stream processing, where the data may have complex dimesions and quickly changing characteristics.
High Accuracy: The capacity to achieve high predictive accuracy is an attribute of deep learning models. Organizations can use deep neural networks to handle data streams and make more precise predictions and decisions based on incoming data.
Scalability: Deep learning models tend to be resource and computationally-intensive. Deploying deep learning models in the circumstances with scarce assets can be difficult due to the computational strain of managing huge amounts of data in real-time using data stream processing.
Data Imbalance: Rare events or anomalies that happen infrequently can cause data streams to become extremely unbalanced. It might be difficult for deep learning models to identify these uncommon occurrences. Real-time strategies for managing unbalanced data are required.
Concept Drift: Data distribution can shift over time because data streams are, by nature, dynamic. It is difficult to modify deep learning models to account for concept drift. One major challenge is ensuring that models stay current and accurate as data changes.
Memory Restrictions: Deep learning models frequently require much memory, particularly when working with big datasets. Memory limitations may be a constraint in data stream processing. It is challenging to establish a memory-efficient deep learning model capable of productively processing data streams.
Real-Time Training: It is difficult to train deep learning models as new information comes in. Online learning algorithms and strategies must be used to update model parameters while maintaining stability and accuracy effectively.
