Study Notes
What is Recurrent Neural Network (RNN)?
- A type of artificial neural network that uses sequential data or time series data.
- Used for ordinal or temporal problems, such as language translation, natural language processing (NLP), speech recognition, and image captioning.
- Incorporated into popular applications such as Siri, voice search, and Google Translate.
How RNNs Work
- Pass sequential data to hidden layers one step at a time.
- Have a self-looping or recurrent workflow: hidden layer can remember and use previous inputs for future predictions in a short-term memory component.
Recurrent Neural Network Types
One-to-One
- Simplest type of RNN, allows a single input and a single output.
- Has fixed input and output sizes, acts as a traditional neural network.
One-to-Many
- Gives multiple outputs when given a single input.
- Takes a fixed input size and gives a sequence of data outputs.
- Applications include Music Generation and Image Captioning.
Many-to-One
- Used when a single output is required from multiple input units or a sequence of them.
- Takes a sequence of inputs to display a fixed output.
Many-to-Many
- Used to generate a sequence of output data from a sequence of input units.
- Divided into two subcategories: Equal Unit Size and Unequal Unit Size.
Equal Unit Size
- Number of both input and output units is the same.
- Application: Name-Entity Recognition.
Unequal Unit Size
- Inputs and outputs have different numbers of units.
- Application: Machine Translation.
Real-Life Example of RNN
- Apple's Siri and Google's voice search both use Recurrent Neural Networks (RNNs).
Information System (IS)
- A coordinated system of hardware, software, infrastructure, data, and people designed to generate, store, process, retrieve, and distribute information.
How IS can benefit from NLP, CNN, & RNN
Natural Language Processing (NLP)
- Helps IS understand and analyze text from emails, social media, or documents.
- Powers chatbots and virtual assistants to answer questions or help with tasks.
- Can summarize large texts automatically, saving time for users.
Convolutional Neural Networks (CNN)
- Help IS understand and analyze images, useful for tasks like identifying objects or scenes.
- Can read scanned documents or handwritten text, helping with tasks like digitizing documents.
Recurrent Neural Networks (RNN)
- Great for tasks involving sequences, like predicting future values in time series data or understanding speech.
- Can analyze user behavior over time to make personalized recommendations, like suggesting movies or products.
