Supervised machine learning uses labeled data to train models for classification or regression over a set of targets. The performance of a model is a function of the data that is used to train it. The less data that is available, the harder it is for a model to learn to make accurate predictions on unseen data.

Convolution Neural Networks (CNN) learns image regognition the way human visual system does. It scans images by using filters which recognizes a unique feature. A little deeper layers identify low level features such as curves and edges, while the deeper layers idtentifies high level features such as eyes or windows. We use Keras library to visualize what CNN are learning to look when making a certain classfication.

In the late 2018 AWS announced two new features for Lambda to make serverless deployment much easier. They are:
· Lambda layers — which is a way to manage code and dependencies across multiple lambda functions.
· Lambda Runtime API — to develop lambda functions on any programming language or a specific language version.

In the 21st century, every person and organization, both public and private, are somehow connected. So, being able to quickly understand and efficiently analyze whether your third-party policy documents such as NIST 800–171, ISO 27001, ISO 9001, etc., meet the standards you set for them is critical to the success of your business. Current policy assessment tools are manual, inefficient, and don’t adequately reduce risk.
We at Mindboard developed a platform to solve these problems. We are utilizing machine-learning, semantic technology, a repository of standard-meeting model documents we provide the most advanced and efficient methodology for automating and evaluating policy documents.

AWS Lambda is a serverless computing service provided by Amazon Web Services. The definition of serverless architecture is — it is a stateless compute container designed for event-driven solutions just like microservice architecture where monolithic applications are broken into simple smaller services which are easy to code, manage and scale.

As deep learning technologies power increasingly more services, associated security risks become more critical to address. Adversarial Machine Learning is a branch of machine learning that exploits the mathematics underlying deep learning systems in order to evade, explore, and/or poison machine learning models. Evasion attacks are the most common adversarial attack method due to their ease of implementation and potential for being highly disruptive. During an evasion attack, the adversary tries to evade a fully trained model by engineering samples to be misclassified by the model. This attack does not assume any influence over the training data.
Evasion attacks have been demonstrated in the context of autonomous vehicles where the adversary manipulates traffic signs to confuse the learning model. Research suggests that deep neural networks are susceptible to adversarial based evasion attacks due to their high degree of non-linearity as well as insufficient model averaging and regularization.

Active learning is a special case of machine learning where a model can query a user for input. In this post, we will see how we can use active learning to label large data sets. For most machine learning tasks, large amounts of labeled data is needed is need for model training. However, the process of labeling data can be extremely time consuming and/or expensive. Using active learning, we can leverage a classification model to do most of the labeling for us, so that we only need to label samples when it is most needed.

A generative adversarial network (GAN) is a system composed of two neural networks: a generator and a discriminator. The discriminator takes a data instance as input, and classifies it as ‘Real’ or ‘Fake’ with respect to a training data set. The generator takes Gaussian noise and transforms it into a synthetic data sample with the goal of fooling the discriminator. The discriminator learns to classify samples as real or fake. The generator learns from errors in failed attempts at fooling the discriminator.
