Tutorial: Achieving High-Quality Search and Recommendation Results with DeepNLP

In this technical blog post, learn how LinkedIn uses deep learning-based NLP technologies to better understand text semantics, which is key to any ranking model.

In this technical blog post, learn how LinkedIn uses deep learning-based NLP technologies to better understand text semantics, which is key to any ranking model.

Speech and natural language processing (NLP) have become the foundation for most of the AI development in the enterprise today, as textual data represents a significant portion of unstructured content. As consumer internet companies continue to improve the accuracy of conversational AI, search, and recommendation systems, there is an increasing need for processing rich text data efficiently and effectively.

However, one of the key challenges for achieving the desired accuracy lies in understanding complex semantics and underlying user intent, and effectively extracting relevant information from a variety of sources such as user queries and documents. In recent years, the rapid development of deep learning models has bolstered improvements for a variety of NLP tasks, indicating the vast potential for further improving the accuracy of search and recommender systems.

In this post, we introduce DeText, a state-of-the-art, open-source NLP framework developed at LinkedIn for text understanding, followed by a summary of the GPU-accelerated BERT assets available for you to jumpstart your NLP development.

Bayes by backprop implementation using tfp

I am trying to implement a simple bayes by backprop regression using the following tutorial

[http://krasserm.github.io/2019/03/14/bayesian-neural-networks/`](http://krasserm.github.io/2019/03/14/bayesian-neural-networks/)“`

But my regressor is no where near learning. below is my model, can anyone suggest a simple implementation of the tutorial?

“`

def prior(kernel_size, bias_size, dtype=None):
n = kernel_size + bias_size
prior_model = tf.keras.Sequential([
tfp.layers.DistributionLambda(
lambda t:tfd.MultivariateNormalDiag(loc=tf.zeros(n), scale_diag=tf.ones(n))
)
])
return prior_model
def posterior(kernel_size, bias_size,dtype=None):
n = kernel_size + bias_size
posterior_model = tf.keras.Sequential([
tfp.layers.VariableLayer(tfp.layers.MultivariateNormalTriL.params_size(n),dtype=dtype),
tfp.layers.MultivariateNormalTriL(n)
])
return posterior_model
model = tf.keras.Sequential([
tfp.layers.DenseVariational(units=20,input_shape=(1,),make_prior_fn=prior, make_posterior_fn=posterior,kl_weight=1/x_train.shape[0]),
tf.keras.layers.ReLU(),
tfp.layers.DenseVariational(units=20,make_prior_fn=prior, make_posterior_fn=posterior,kl_weight=1/x_train.shape[0]),
tfp.layers.DenseVariational(units=1,make_prior_fn=prior, make_posterior_fn=posterior,kl_weight=1/x_train.shape[0])
])
model.compile(loss=tf.keras.losses.MeanSquaredError() , optimizer=tf.keras.optimizers.Adam(lr=0.001),metrics=[‘mae’])
print(model.summary())
history = model.fit(x_train, y_train, batch_size=batch_size, epochs=500,verbose=2)

New Programmer question

New Programmer question

Hello everyone. I am an M.D. I am doing medical data analysis (not image at least now), I am using Matlab . I have seen TensorFlow, I wander is it worth for me to learn it? to make regression analysis KM plots etc. ? I tried to install to give a try. I wanted to use swift for tensor flow into Xcode. I couldn’t make it work. I installed the package. I can see that on toolchains.

can someone give me an idea about Tensor Flow , if it is worth to use for me ?

Any thoughts on measuring the water level of a glass using vision

I am thinking about the possibilities of measuring the water quantity of a container using any vision system.

I come across time of flight cameras which can work on short ranges and can give water level.

I would like to know about your thoughts on that.

The ants and the pheromones

TLDR; this is the last edition of The Morning Paper for now. Plus: one strand of research you won’t want to miss!

I was listening to a BBC Radio 4 podcast recently (More or Less: Behind the Stats – Ants and Algorithms) in which the host Tim Harford is interviewing David Sumpter about his recent book, ‘The ten equations that rule the world.’ One of those equations, the ‘reward equation’ models how ants communicate using pheromones, and our own brains keep track of rewards using dopamine.

About 4 and a half minutes into the podcast Tim asks a fascinating question: the reward equation includes a decay or ‘forgetting’ parameter, so what happens if you disrupt established solutions for long enough that their hold is broken? For example, the complete disruption to our established routines that Covid has caused over the last year? The answer for ants, if you disrupt all of the pheromone trails around their nest, is that they converge on a new solution in the environment, but it won’t necessarily look the same as the one they had before the disruption. (If you’re interested in the amazing problem-solving skills of ants and how we can learn from them in computer science, I covered ‘Ant algorithms for discrete optimization’ in a previous edition of The Morning Paper). It’s highly likely that the same thing will happen to us when we can eventually return to normal – the patterns that we establish won’t necessarily be the same as the ones we had before the series of lockdowns began.

The lockdowns (as I write this, we’re in another strict lockdown in England, with no end date given) have certainly disrupted my own routines. I’ve lost the time and space that I depended on for studying and writing The Morning Paper – the one-hour each way train journey on my morning commute, and more crucially with two older children both full-time studying from home, the time and space within the home for the many hours of concentrated work required. I don’t think my love of learning will ever leave me though, and at the same time I’ve been branching out and studying other things: philosophy, ethics, physics, a little maths, a little biology,… I’m really enjoying that. My love of computer science remains of course, but when we finally get to lay down our new pheromone trails and establish a new normal, I’m not sure I’m going to want to focus on computer science to the exclusion of all else. It’s been an intense six-and-a-half years doing largely that while writing the blog. For the time being then, I’m putting The Morning Paper back on pause.

Before I wrap up though, I can’t resist pointing you in the direction of one incredibly exciting research project from the Hydro team at Berkeley’s RISELab. Joe Hellerstein recently posted a whole bunch of links and resources in this Twitter thread:

The “PACT” paper is here: New Directions in Cloud Programming, Cheung et al., CIDR 2021.

Suggestions on building machine transliteration models

I’m trying to build a english to assamese transliteration model. I tried character level NMT with attention, but not satisfied with the results, considering the Assamese language consists of prefix/suffixes. Currently exploring WFST. Has anybody worked on something similar?
