Why we use LSTM instead of RNN?

We can say that, when we move from RNN to LSTM (Long Short-Term Memory), we are introducing more & more controlling knobs, which control the flow and mixing of Inputs as per trained Weights. And thus, bringing in more flexibility in controlling the outputs.

Can we use RNN for image processing?

Unlikely to CNN, RNN learns to recognize image features across time. Although RNN can be used for image classification theoretically, only a few researches about RNN image classifier can be found.

What RNN problem is solved using LSTM?

LSTMs solve the problem using a unique additive gradient structure that includes direct access to the forget gate’s activations, enabling the network to encourage desired behaviour from the error gradient using frequent gates update on every time step of the learning process.

Can we use Lstm for image classification?

Yes, the LSTM model can be applied for image classification. But you have first to extract features from images, then you can apply the LSTM model.

Can RNN perform better than LSTM?

After learning about these 3 models, we can say that RNN’s perform well for sequence data but has short-term memory problem(for long sequences). It doesn’t mean to use GRU/LSTM always. Simple RNN has it’s own advantages (faster training, computationally less expensive).

What is an LSTM in RNN?

LSTMs enable RNNs to remember inputs over a long period of time. This is because LSTMs contain information in a memory, much like the memory of a computer. The LSTM can read, write and delete information from its memory. In an LSTM you have three gates: input, forget and output gate.

What is an RNN algorithm?

The algorithm performs very well for sequential data such as time series, speech, text, financial data, audio, video, weather, and more. RNNs are able to form a much deeper understanding of a sequence and its context compared to other algorithms. In an RNN, the information goes through a cycle.

What is an RNN (recurrent neural network)?

RNNs are a robust and powerful type of neural network and are considered one of the most professional algorithms because they are the only ones with internal memory. Recurrent neural networks were first created in the 1980s, but only in recent years has their true potential been realized.

Is there a multiobject tracking algorithm based on long short term memory?

Multiple-object tracking is a challenging issue in the computer vision community. In this paper, we propose a multiobject tracking algorithm in videos based on long short-term memory (LSTM) and deep reinforcement learning. Firstly, the multiple objects are detected by the object detector YOLO V2.
