Biostatistical Analysis and Wavelet Analysis are widely utilized in various fields such as image processing, statistical learning, medical informatics, and so on. Both Biostatistical Analysis and Wavelet Analysis are still ongoing and applied to many fields. On the other hand, Validated Numerics is developed and expected to bridge the gap between a numerically observed phenomenon, and its mathematical counterpart, and it is expected to improve the accuracy of analysis and adequately deal with uncertain data in actual computation. In the track on Biostatistical Analysis, Wavelet Analysis and Validated Numerics, we intend to share the recent and advanced topics of these three fields and discuss new possibilities for developing new methods combining specialized knowledge of these fields.
