Designing neuromorphic sensory processing units (NSPUs) based on Temporal Neural Networks (TNNs) is a highly challenging task due to the reliance on manual, labor-intensive hardware development processes. TNNs have been identified as highly promising for real-time edge AI applications, mainly because they are energy-efficient and bio-inspired. However, available methodologies lack automation and are not very accessible. Consequently, the design process becomes complex, time-consuming, and requires specialized knowledge. It is through overcoming these challenges that one can unlock the full potential of TNNs for efficient and scalable processing of sensory signals. The current approaches to TNN development are fragmented workflows, as

An increasingly popular method for representing data in a graph structure is the usage of knowledge graphs (KGs). A KG is a group of triples (s, p, o), where s (subject) and o (object) are two graph nodes, and p is a predicate that describes the type of connection that exists between them. KGs are often supported by a schema (such as an ontology) that outlines the key ideas and relationships in a field of study and the constraints that govern how these ideas and relationships can interact. Many of the activities for which KGs are employed have a small

Python has become the most popular language in many rapidly evolving sectors, such as deep learning and data sciences. Yet its easy readability comes at the cost of performance. Of course, we all complain about program performance from time to time, and Python should certainly not take all the blame. Still, it's fair to say that Python's nature as an interpreted language does not help, especially in computation-intensive scenarios (e.g., when there are multiple nested for loops).

Linear algebra is essential to deep learning and scientific computing, and it’s always been a core part of PyTorch. PyTorch 1.9 extends PyTorch’s support for linear algebra operations with the torch.linalg module. This module, documented here, has 26 operators, including faster and easier to use versions of older PyTorch operators, every function from NumPy’s linear algebra module extended with accelerator and autograd support, and a few operators that are completely new. This makes the torch.linalg immediately familiar to NumPy users and an exciting update to PyTorch’s linear algebra support.

Uplift models seek to predict the incremental value attained in response to a treatment. For example, if we want to know the value of showing an advertisement to someone, typical response models will only tell us that a person is likely to purchase after being given an advertisement, though they may have been likely to purchase already. Uplift models will predict how much more likely they are to purchase after being shown the ad. The most scalable uplift modeling packages to date are theoretically rigorous, but, in practice, they can be prohibitively slow. We have written a Python package, pylift, that implements a transformative method wrapped around scikit-learn to allow for (1) quick implementation of uplift, (2) rigorous uplift evaluation, and (3) an extensible python-based framework for future uplift method implementations.

A context-preserving word cloud generator.
Recently I’ve started using PyMC3 for Bayesian modelling, and it’s an amazing piece of software! The API only exposes as much of heavy machinery of MCMC as you need — by which I mean, just the pm.sample() method (a.k.a., as Thomas Wiecki puts it, the Magic Inference Button™). This really frees up your mind to think about your data and model, which is really the heart and soul of data science! That being said however, I quickly realized that the water gets very deep very fast: I explored my data set, specified a hierarchical model that made sense to me, hit the Magic Inference Button™, and… uh, what now? I blinked at the angry red warnings the sampler spat out.

Last time we saw a geometric version of the algorithm to add points on elliptic curves. We went quite deep into the formal setting for it (projective space $ \mathbb{P}^2$), and we spent a lot of time talking about the right way to define the “zero” object in our elliptic curve so that our issues with vertical lines would disappear. With that understanding in mind we now finally turn to code, and write classes for curves and points and implement the addition algorithm.
Python decorators are a useful but flawed language feature. Intended to make source code easier to write, and a little more readable, they neglect to address another use case: that of the programmer who will be calling the decorated code. If you’re a Python programmer, the following post will show you why decorators exist, and how to compensate for their limitations. And even if you’re not a Python a programmer, I hope to demonstrate the importance of keeping in mind all of the different audiences for the code you write.

The challenge of managing and recalling facts from complex, evolving conversations is a key problem for many AI-driven applications. As information grows and changes over time, maintaining accurate context becomes increasingly difficult. Current systems often struggle to handle the evolving nature of relationships and facts, leading to incomplete or irrelevant results when retrieving information. This can affect the effectiveness of AI agents, especially when dealing with user memories and context in real-time applications. Some existing solutions have attempted to address this problem. One common approach is using a Retrieval-Augmented Generation (RAG) pipeline, which involves storing extracted facts and using techniques

Extracting structured data from unstructured sources like PDFs, webpages, and e-books is a significant challenge. Unstructured data is common in many fields, and manually extracting relevant details can be time-consuming, prone to errors, and inefficient, especially when dealing with large amounts of data. As unstructured data continues to grow exponentially, traditional manual extraction methods have become impractical and error-prone. The complexity of unstructured data in various industries that rely on structured data for analysis, research, and content creation. Current methods for extracting data from unstructured sources, including regular expressions and rule-based systems, are often limited by their inability to maintain
