Introduction :

Autoencoding” is a data compression algorithm where the compression and decompression functions are:

  1. lossy : which means that the decompressed outputs will be degraded compared to the original inputs
  2. learned automatically from examples rather than engineered by a human : which means that it is easy to train specialised instances of the algorithm that will perform well on a specific type of input. It doesn’t require any new engineering, just appropriate training data.

It is an unsupervised learning technique in…


Introduction :

Named-entity recognition (NER) (also known as entity identification, entity chunking and entity extraction) is a subtask of information extraction that seeks to locate and classify named entities mentioned in unstructured text into pre-defined categories such as person names, organisations, locations, medical codes, time expressions, quantities, monetary values, percentages, etc.

It adds a wealth of semantic knowledge to your content and helps you to promptly understand the subject of any given text.

Applications :

Few applications of NER include: extracting important named entities from legal, financial, and medical documents, classifying content for news providers, improving the search algorithms, and etc.

Approaches to tackle this problem:

  1. Machine Learning Approach…

AWS SageMaker

Introduction to AWS SageMaker.

Amazon SageMaker is a fully managed service that provides every developer and data scientist with the ability to build, train, and deploy machine learning (ML) models quickly. SageMaker removes the heavy lifting from each step of the machine learning process to make it easier to develop high-quality models.

It can build models trained by data dumped into the S3 buckets, or a streaming data source like Kinesis shards. Once models are trained, SageMaker allows us to deploy them into production without any effort.


If a human investor can be successful, why can’t a machine?

Machine Learning and deep learning have become new and effective strategies commonly used by quantitative hedge funds to maximise their profits.

This article will be an introduction on how to use neural networks to predict the stock market, in particular, whether to buy or sell your stocks and make the right investments.


Time series is different from more traditional classification and regression predictive modeling problems.

The temporal nature adds an order to the observations. This imposed order means that important assumptions about the consistency of those observations needs to be handled specifically.

The ability to make predictions based upon historical observations creates a competitive advantage. For example, if an organization has the capacity to better forecast the sales quantities of a product, it will be in a more favourable position to optimize inventory levels. …


Introduction

Caption generation is a challenging artificial intelligence problem where a textual description must be generated for a given photograph.It requires both methods from computer vision to understand the content of the image and a language model from the field of natural language processing to turn the understanding of the image into words in the right order.

A “classic” image captioning system would encode the image, using a pre-trained Convolutional Neural Network(ENCODER) that would produce a hidden state h.

Then, it would decode this hidden state by using a LSTM(DECODER) and generate recursively each word of the caption.


Introduction

Calibration in classification means turning transform classifier scores into class membership probabilities.

Instead of predicting class values directly for a classification problem, it can be convenient to predict the probability of an observation belonging to each possible class.
