In this paper, we investigate the ability of single-layer attention-only transformers (i.e. attention layers) to memorize facts contained in databases from a linear-algebraic perspective. We associate with each database a 3-tensor, propose the rank of this tensor as a measure of the size of the database, and provide bounds on the rank in terms of properties of the database. We also define a 3-tensor corresponding to an attention layer, and empirically demonstrate the relationship between its rank and database rank on a dataset of toy models and random databases. By highlighting the roles played by the value-output and query-key weights, and the effects of argmax and softmax on rank, our results shed light on the `additive motif' of factual recall in transformers, while also suggesting a way of increasing layer capacity without increasing the number of parameters.

Traditional methods, such as JPEG, perform image compression by operating on structural information, such as pixel values or frequency content. These methods are effective to bitrates around one bit per pixel (bpp) and higher at standard image sizes. In contrast, text-based semantic compression directly stores concepts and their relationships using natural language, which has evolved with humans to efficiently represent these salient concepts. These methods can operate at extremely low bitrates by disregarding structural information like location, size, and orientation. In this work, we use GPT-4V and DALL-E3 from OpenAI to explore the quality-compression frontier for image compression and identify the limitations of current technology. We push semantic compression as low as 100 $\mu$bpp (up to $10,000\times$ smaller than JPEG) by introducing an iterative reflection process to improve the decoded image. We further hypothesize this 100 $\mu$bpp level represents a soft limit on semantic compression at standard image resolutions.

A common assumption when training embodied agents is that the impact of taking an action is stable; for instance, executing the "move ahead" action will always move the agent forward by a fixed distance, perhaps with some small amount of actuator-induced noise. This assumption is limiting; an agent may encounter settings that dramatically alter the impact of actions: a move ahead action on a wet floor may send the agent twice as far as it expects and using the same action with a broken wheel might transform the expected translation into a rotation. Instead of relying that the impact of an action stably reflects its pre-defined semantic meaning, we propose to model the impact of actions on-the-fly using latent embeddings. We evaluate our AAP on two challenging visual navigation tasks in the AI2-THOR and Habitat environments and show that our AAP is highly performant even when faced, at inference-time with missing actions and, previously unseen, perturbed action space. Moreover, we observe significant improvement in robustness against these actions when evaluating in real-world scenarios. Humans show a remarkable capacity for planning when faced with substantially constrained or augmented means by which they may interact with their environment. For instance, a human who begins to walk on ice will readily shorten their stride to prevent slipping. Likewise, a human will spare little mental effort in deciding to exert more force to lift their hand when it is weighed down by groceries. Even in these mundane tasks, we see that the effect of a humans' actions can have significantly different outcomes depending on the setting: there is no predefined one-to-one mapping between actions and their impact. The same is true for embodied agents where something as simple as attempting to moving forward can result in radically different outcomes depending on the load the agent carries, the presence of surface debris, and the maintenance level of the agent's actuators (e.g., are any wheels broken?). We call this the action-stability assumption (AS assumption).

Creating efficiencies in your business is at the top of your list. You want your employees to be more productive, have them focus on high impact tasks, or find ways to implement better processes to improve the outcomes to your customers. There are various ways to solve this problem, and more companies are turning to artificial intelligence (AI) and machine learning (ML) to help. In the financial services sector, there is the creation of new accounts online, or in healthcare there are new digital platforms to schedule and manage appointments, which require users to fill out forms. These can be error prone, time consuming, and certainly improved upon.

Machine learning (ML) is an innovative tool that advances technology in every industry around the world. Due to its constant learning and evolution, the algorithms are able to adapt based on success and failure. Then, they can help people in daily life. Machine learning mimics the human brain. It entails deep learning from its neural networks, natural language processing (NLP), and constant changes based on incoming information. Of course, these algorithms aren't perfect, but they become more refined with every interaction.

With two releases every year, you may find it challenging to keep up with the latest features.* In fact, some people who work here feel the same way! This release, I asked the Product Managers about the new features related to deep learning that they think you should know about in release 20a. Here are their responses: Deep Learning Starting with Deep Learning Toolbox, there are three new features to get excited about in 20a.
