Recurrent Neural Networks have shown to be very powerful models as they can propagate context over several time steps. Due to this they can be applied effectively for addressing several problems in Natural Language Processing, such as Language Modelling, Tagging problems, Speech Recognition etc. In this presentation we introduce the basic RNN model and discuss the vanishing gradient problem. We describe LSTM (Long Short Term Memory) and Gated Recurrent Units (GRU). We also discuss Bidirectional RNN with an example. RNN architectures can be considered as deep learning systems where the number of time steps can be considered as the depth of the network. It is also possible to build the RNN with multiple hidden layers, each having recurrent connections from the previous time steps that represent the abstraction both in time and space.
This presentation on Recurrent Neural Network will help you understand what is a neural network, what are the popular neural networks, why we need recurrent neural network, what is a recurrent neural network, how does a RNN work, what is vanishing and exploding gradient problem, what is LSTM and you will also see a use case implementation of LSTM (Long short term memory). Neural networks used in Deep Learning consists of different layers connected to each other and work on the structure and functions of the human brain. It learns from huge volumes of data and used complex algorithms to train a neural net. The recurrent neural network works on the principle of saving the output of a layer and feeding this back to the input in order to predict the output of the layer. Now lets deep dive into this presentation and understand what is RNN and how does it actually work.

Much of data is sequential – think speech, text, DNA, stock prices, financial transactions and customer action histories. Modern methods for modelling sequence data are often deep learning-based, composed of either recurrent neural networks (RNNs) or attention-based Transformers. A tremendous amount of research progress has recently been made in sequence modelling, particularly in the application to NLP problems. However, the inner workings of these sequence models can be difficult to dissect and intuitively understand.
This presentation/tutorial will start from the basics and gradually build upon concepts in order to impart an understanding of the inner mechanics of sequence models – why do we need specific architectures for sequences at all, when you could use standard feed-forward networks? How do RNNs actually handle sequential information, and why do LSTM units help longer-term remembering of information? How can Transformers do such a good job at modelling sequences without any recurrence or convolutions?
In the practical portion of this tutorial, attendees will learn how to build their own LSTM-based language model in Keras. A few other use cases of deep learning-based sequence modelling will be discussed – including sentiment analysis (prediction of the emotional valence of a piece of text) and machine translation (automatic translation between different languages).
The goals of this presentation are to provide an overview of popular sequence-based problems, impart an intuition for how the most commonly-used sequence models work under the hood, and show that quite similar architectures are used to solve sequence-based problems across many domains.
"Mainstream access to deep learning technology will greatly impact most industries over the next three to five years."
So what exactly is deep learning? How does it work? And most importantly, why should you even care?
Deep learning is used in the research community and in industry to help solve many big data problems such as computer vision, speech recognition, and natural language processing.
Practical examples include:
-Vehicle, pedestrian and landmark identification for driver assistance
-Image recognition
-Speech recognition and translation

EXPERIMENTS ON DIFFERENT RECURRENT NEURAL NETWORKS FOR ENGLISH-HINDI MACHINE ...csandit
Recurrent Neural Networks are a type of Artificial Neural Networks which are adept at dealing
with problems which have a temporal aspect to them. These networks exhibit dynamic
properties due to their recurrent connections. Most of the advances in deep learning employ
some form of Recurrent Neural Networks for their model architecture. RNN's have proven to be
an effective technique in applications like computer vision and natural language processing. In
this paper, we demonstrate the effectiveness of RNNs for the task of English to Hindi Machine
Translation. We perform experiments using different neural network architectures - employing
Gated Recurrent Units, Long Short Term Memory Units and Attention Mechanism and report
the results for each architecture. Our results show a substantial increase in translation quality
over Rule-Based and Statistical Machine Translation approaches.

Applying Deep Learning Machine Translation to Language ServicesYannis Flet-Berliac
Recurrent neural networks (RNNs) have been performing well for learning tasks for several decades now. The most useful benefit they present for this paper is their ability to use contextual information when mapping between input and output sequences.
A deep neural network for machine translation implies the use of a sequence-to-sequence model, consisting of two RNNs: an encoder that processes the input and a decoder that generates the output.
To meaningfully assess the model’s performances, texts from a translation company and thoughts from skilled experts about specialized topics will be tested.

Spoofing attack on PMU (Phasor measurement unit)Mohammad Sabouri
A phasor measurement unit (PMU) is a device used to estimate the magnitude and phase angle of an electrical phasor quantity (such as voltage or current) in the electricity grid using a common time source for synchronization. Time synchronization is usually provided by GPS and allows synchronized real-time measurements of multiple remote points on the grid. PMUs are capable of capturing samples from a waveform in quick succession and reconstructing the phasor quantity, made up of an angle measurement and a magnitude measurement. The resulting measurement is known as a synchrophasor. These time synchronized measurements are important because if the grid’s supply and demand are not perfectly matched, frequency imbalances can cause stress on the grid, which is a potential cause for power outages.

2024.06.01 Introducing a competency framework for languag learning materials ...Sandy Millin
http://sandymillin.wordpress.com/iateflwebinar2024
Published classroom materials form the basis of syllabuses, drive teacher professional development, and have a potentially huge influence on learners, teachers and education systems. All teachers also create their own materials, whether a few sentences on a blackboard, a highly-structured fully-realised online course, or anything in between. Despite this, the knowledge and skills needed to create effective language learning materials are rarely part of teacher training, and are mostly learnt by trial and error.
Knowledge and skills frameworks, generally called competency frameworks, for ELT teachers, trainers and managers have existed for a few years now. However, until I created one for my MA dissertation, there wasn’t one drawing together what we need to know and do to be able to effectively produce language learning materials.
This webinar will introduce you to my framework, highlighting the key competencies I identified from my research. It will also show how anybody involved in language teaching (any language, not just English!), teacher training, managing schools or developing language learning materials can benefit from using the framework.

This is a presentation by Dada Robert in a Your Skill Boost masterclass organised by the Excellence Foundation for South Sudan (EFSS) on Saturday, the 25th and Sunday, the 26th of May 2024.
He discussed the concept of quality improvement, emphasizing its applicability to various aspects of life, including personal, project, and program improvements. He defined quality as doing the right thing at the right time in the right way to achieve the best possible results and discussed the concept of the "gap" between what we know and what we do, and how this gap represents the areas we need to improve. He explained the scientific approach to quality improvement, which involves systematic performance analysis, testing and learning, and implementing change ideas. He also highlighted the importance of client focus and a team approach to quality improvement.

3. Recurrent Neural Network
A Recurrent Neural Network (RNN) is a class of artificial neural
network that has memory or feedback loops that allow it to better
recognize patterns in data.
• Recurrent neural network (RNN) is a neural network model
proposed in the 80’s for modelling time series.
RNNs are an extension of regular artificial neural networks that add connections
feeding the hidden layers of the neural network back into themselves - these are called
recurrent connections.
4. Recurrent Neural Network
The structure of the network is similar to feedforward neural network, with t
he distinction that it allows a recurrent hidden state whose activation at each
time is dependent on that of the previous time (cycle).
5. Recurrent Neural Network
• Recurrent networks, on the other hand, take as their input not just the current input exa
mple they see, but also what they have perceived previously in time.
• This enables RNNs to have improved accuracy compared to MLPs, which only have t
he single input and no memory, RNNs can take several prior input and extrapolate out
with improved accuracy. In other words, RNNs take into consideration what it has lear
ned from prior inputs to classify the current input.
6. Some Example of Recurrent
Neural Network
The beauty of recurrent neural networks lies in their diversity of applicati
on. When we are dealing with RNNs they have a great ability to deal wit
h various input and output types.
• Sentiment Classification
• Image Captioning
• Language Translation
7. Some example of Recurrent
Neural Network
Sentiment Classification
This can be a task of simply classifying tweets into positive and negative sentiment. So he
re the input would be a tweet of varying lengths, while output is of a fixed type and size.
8. Some Example of Recurrent
Neural Network
• Image Captioning
Here, let’s say we have an image for which we need a textual description. So we have a si
ngle input – the image, and a series or sequence of words as output. Here the image might
be of a fixed size, but the output is a description of varying lengths
9. Some Example of Recurrent
Neural Network
• Language Translation
This basically means that we have some text in a particular language let’s say English, an
d we wish to translate it in French. Each language has it’s own semantics and would have
varying lengths for the same sentence. So here the inputs as well as outputs are of varying
lengths.
10. Recurrent Neural Network
So RNNs can be used for mapping inputs to outputs of varying types, lengths and are fairly
generalized in their application. Looking at their applications
11. Where to use a RNN?
• Language Modelling and Generating Text
Given a sequence of word, here we try to predict the likelihood of the next wo
rd. This is useful for translation since the most likely sentence would be the on
e that is correct.
• Machine Translation
Translating text from one language to other uses one or the other form of RN
N. All practical day systems use some advanced version of a RNN.
• Speech Recognition
Predicting phonetic segments based on input sound waves, thus formulating a
word.
12. Where to use a RNN?
• Generating Image Descriptions
A very big use case is to understand what is happening inside an image, thus
we have a good description. This works in a combination of CNN and RNN. C
NN does the segmentation and RNN then used the segmented data to recreat
e the description. It’s rudimentary but the possibilities are limitless.
• Video Tagging
This can be used for video search where we do image description of a video fr
ame by frame.
15. Mathematical Formulation
Recurrent neural networks learn from sequences. A sequence is define
d as a list of (xi,yi) pairs, where xi is the input at time i and yi is the d
esired output. Note that that is a single sequence; the entire data set co
nsists of many sequences.
16. Mathematical Formulation
In addition to the data in our data set, each time step has another input: the hidden state hi−1
from the previous time step. In this way, the recurrent neural network can maintain some int
ernal context as it progresses forward in the sequence. Thus, to summarize, at time i the rec
urren
t network has:
• Input vector xi (data)
• Output vector yi (data)
• Predicted output vector y^i(computed through forward propagation)
• Hidden state hi
17. Mathematical Formulation
When looking only at a single timestep, the recurrent network looks like a simple one-hidden-
layer feed forward network. It has an input layer for xi, an output layer for yi, and another inp
ut layer for the previous hidden state hi−1. Finally, it has one hidden layer between these. The
only unusual thing is that we have two input layers; both of the input layers are are connected
to the hidden layer as if they were really just a single layer.
Thus, we have three separate matrices of weights:
• Input-to-hidden weights Whx
• Hidden-to-hidden weights Whh
• Hidden-to-output weights Wyh
18. Mathematical Formulation
There are several things to note here. First of all, note that the predicted outputs are not su
bject to the nonlinearity. We may want to predict things other than the things in the range
of the nonlinearity, so instead we do not apply the nonlinearity. For specific use cases of r
ecurrent nets, this can be amended, and a nonlinearity specific to the problem can be chos
en. Finally, note that these equations are the same as the equations for a single hidden lay
er feed forward network, with the caveat that the input layer is broken into two pieces xi a
nd hi−1.
22. Jordan RNN
Pro: Fast to train because can be parallelized in time
Cons:
• Output transforms hidden state → nonlinear effects, information distorted
• The output dimension may be too small → information in hidden states is t
runcated
23. Elman RNN
Often referenced as the basic RNN structure and called “Vanilla” RNN
• Should see complete sequence to be trained
• Can not be parallelized by timestamps
• Has some important training difficulties….
28. RNN Problem
However, conventional RNNs have a few limitations. They are difficult to train and have a
very short-term memory, which limits their functionality. To overcome the memory limitatio
n, a newer form of RNN, known as LSTM or Long Short-term Memory networks are used.
LSTMs extend the memory RNNs to enable them to perform tasks involving longer-term m
emory.
