ABOUT

In this era, not only lifestyles and ways of life, but also risks such as pandemics are diversifying. We at VELDT believe that the various lifelogs that are produced every day hide great hints for changing the lives of individuals with different interests and goals. We will innovate how to utilize the data produced in the real world. We will pursue the following three themes: "Realization of personalized wellness" that is close to one person, "Preventive shift from cure to care" this increases the time that can be active in health and leads to efficiency of medical resources, and lastly "Supporting healthcare innovation from various industries" this is needed because of the care-centered era. VELDT is a data science company that creates a positive spiral in each person's life and future society.

The Innovation Issue:
just having data is not enough

In our survey of 200 people working for companies that are implementing or planning businesses in wellness and healthcare, approximately 90% answered that they have problems in setting ideas and themes. Of these, 60% recognize that they have data at hand but have not fully utilized it, and about 50% recognize that they rely on their personal experience and intuition.

Two Different Worlds of Health Data

Our data as patients and subjects are obtained for evidence purposes for medical treatment, testing, and research. While this data is highly reliable and accurate which is used in medicine and research, they are acquired infrequently, such as several times a year. Companies also accumulate data in specific areas that can be used in the health field. On the other hand, we in our daily lives produce life logs every day through wearables and apps. This data is often missing and varies in accuracy, but it can be obtained in time series or high frequency. Currently, due to differences in the accuracy, nature and handling of data, there is a chasm in utilizing these two types of data at the same time.

cover

Discover and virtually validate potential healthcare needs from data

Intermittent and highly reliable data available in the medical and research fields along with daily life log data, which are less reliable but have hints of what happened during that time, are a good complement to each other if the shortcomings are compensated for. By organizing and structuring data, exploring its mechanisms and causal relationships, VELDT provides a mechanism to assist companies and institutions in finding solutions to new problems in virtual verification of hypotheses. We believe that the ability to conduct a virtual validation process prior to conducting a clinical trial or experiment will lead to a more effective experimental design and results.

Our two approaches

Our Smallytics™ technology organizes the lifelog of users, which tends to be fragmented with many missing pieces, to help users manage their physical condition. It displays the symptoms of ailments and factors that may be related to the improvement of physical condition. xCausal is a platform that links these organized data with the data possessed by companies or institutions and utilizes it for innovation.

Service Outline

xCausal is a Web service for companies
and medical institutions used in conjunction with the app

xCausal uses you'd™, a conditioning AI app that makes physical condition discoveries by utilizing smartphone lifelogs. In addition, Smallytics™ is a powered algorithmic engine that links data from the user at a company or medical institution. The user's data that is within companies and medical institutions can be linked and used with permission. The data is anonymized and statistically processed before being used through VELDT's cloud-based dashboards and causal inference engine.

※ It is also possible to use your data alone without linking to the application.

Service overview and process flow

"Health Data Plug-in" service for general corporate customers

To use xCausal, you must first register your company on the web. If you wish to link your lifelogs with the app, you will need to obtain a personal code from the web and distribute it to your company's users. When using the app, the target user enters the assigned personal code into the app and will need to consent to the data linkage. Consent can be given on the app screen after downloading our personal conditioning AI app you'd™ (also available as a white label). You will upload your own data from the web and link it with your personal code (no personal information is required). After the data is linked, you can use the xCausal service in an anonymized and statistical form. It is also possible to upload your own data in csv format for use without linking to the application. The data that can be used via the app is the health data in the user's iOS™ Health Care on the user's smartphone or in Google Fit when the Android™ version is released. In addition, data on physical condition, symptoms, and habits entered by the user in "you'd™". The number of users will be limited to a small number. Items with a small number of users will be displayed when we have enough people and data to display them.

"Medical Assist" service for physicians and medical institutions

The "Medical Assist" service is mainly intended for online health consultation and online medical care, and is available upon confirmation of the physician's credentials at the time of Web application. The process flow and data linkage is the same, but when obtaining consent, the user (patient) is asked to agree to disclose his/her health data and physical condition/illness symptoms on an individual basis. You can check the health data of the user by searching by his/her personal ID.

Infering causal structures and causal effects from data

The Causal Inference Option service allows you to infer causal structures from your data. The inferred structure can be modified as needed. In addition, a hypothetical "What-If ? (What-If ?)" changes can be made to simulate causal effects. The following is a simple example. "If I could double my daily steps, how would my blood pressure change?" It is possible to get an immediate prediction for such a question. As in the case below, after removing the influence from common causes (confounders) that affect both steps and blood pressure, the direct effect from steps on blood pressure can also be calculated to see the distribution of values before and after a hypothetical intervention. More advanced validation is available in the advanced version.

e.g. “how would sleep efficiency change if we could double our daily exercise?”

Quick modeling to assist discovery from data

Estimating the structure of a causal graph from a large number of data items requires a long computational process due to the increase in the number of combinations. In xCausal, Smallytics™ is an algorithm developed in-house that calculates and recommends data combinations that are highly relevant in consideration of causality. By using the recommendations to narrow down the number of items, a causal graph can be generated immediately. Because items can be replaced and interventions can be made immediately, trials of causal effects can be repeated quickly, leading to discoveries that have never been made before.

About Linked Apps

Collaborative apps used by users
you'd™

cover

you'd™ is an app that utilizes your daily activity and lifelog data stored in your smartphone to provide useful discoveries for managing your physical condition. The app automatically calculates and displays what is likely to affect you by inputting your own physical condition, symptoms when you are unwell, and habits that you are implementing to manage your physical condition.
you'd™ can be white-labeled and custom-made. You can incorporate it into your own service by changing the UI design, logo, etc., and customizing branding and functions.

Smallytics™ OEM (SDK provided) and
white label instructions

It is possible to use our health day for smartphones and analysis algorithm Smallytics™ as an SDK for existing apps. Smallytics™ has a structure that cooperates with VELDT's mother AI, and we plan to send parameters learned from anonymized data accumulated in the cloud to Smallytics™ for reinforcement. This provides a mechanism for continuously improving intelligence.

Service Menu

Consists of two basic services and
a causal inference option service

xCausal consists of two basic services with different usage patterns for general enterprises and physicians / medical institutions, and an optional causal inference service. The service for physicians and medical institutions provides access to the health data of individual users (or patients), subject to confirmation of medical qualifications.

Health Data Plug-in Service (for general companies)
By linking your company's data with health data based on the user's permission, you're able to rank in relation to the physical condition, symptoms of illness, and trend comparisons. You can use the service for one month free of charge by registering your credit card.
Medical Assist Service (for physicians and medical institutions)
By linking your company's data with health data based on the user's permission, you're able to rank in relation to physical condition, symptoms of illness, and trend comparisons. Personal data will be disclosed to physicians and medical institutions with the user's consent. This makes it possible to check the health data of individual users by searching with their personal IDs. Please contact us for details.
Causal Inference Basic Version
Based on statistical data from multiple users, causal graphs can be generated, causal relationships can be inferred for analyzed items, and causal effects can be calculated virtually. Efficient processing is achieved by utilizing relevance rankings pre-computed by VELDT's Smallytics algorithm.
Causal Inference Advanced Version
In addition to the agile causal inference and calculation of intervention effects that the Basic Version provides, the Advanced Version adds robustness assessment capabilities to test the reliability of the generated model and the ability to search for scientific papers on the spot that relate to the relationships found. This allows for a broader examination of the hypotheses obtained from the data. Also, the hypotheses derived from the data can be verified from a wide range of perspectives. In addition, the software includes functions to enhance the analysis of the causal relationships obtained.
Customization
Various customizations are possible. Customization of apps and systems, development of dedicated systems, etc.
